The cause of Yunnan Sudden Death Syndrome revealed: mushrooms

A friend of mine posted this article from the BBC concerning the lethal poisoning of over 400 Chinese people in Yunnan province. The Yunnan Sudden Death Syndrome had been observed for over 30 years, and the cause has recently come to light. A small mushroom, Trogia sp. (Marasmiaceae), has been found to produce toxic amino acids, which may be acting synergistically with environmental barium. Interestingly, the Yunnan province is known for its wild mushrooms, many of which are exported around the world. This Trogia, however, has been deemed too small to be marketable, and is eaten locally.

Humungus Fungus Fest

Coming up 12-15 August 2010, the Humungus Fungus Fest in Crystal Falls, Michigan. The festival pays tribute to the Armillaria bulbosa thallus which lives is the area.

Armillaria
spp. are basidiomycete, mushroom-forming fungi which feed off living and dead plant roots and stems, decaying them in the process. There are some situations where Armillaria can be an aggressive pathogen, killing even otherwise healthy individuals, but many are weakly pathogenic, opportunistic, or saprobic. The taxonomy of Armillaria has been rather confused, but is being worked out using molecular (DNA-based) tools. Also using these tools, and also through cultural experiments, it has been shown that single genetic individuals (genets) can be found occupying very large areas. The humongous fungus near Crystal Falls is estimated to cover 38 acres, and be at least 1,500 years old, and may be as much as 10,000 years old. The report was published in the prestigious journal, Nature. An excellent and more accessible summary of the article can be found here.

I think this has to rate as one of the top coolest things about fungi. Because this giant living organism is, most of the time, almost totally invisible. Armillaria does produce mushrooms, but only when conditions are right. The body of an Armillaria (or thallus, in mycospeak) is comprised predominantly of microscopically fine threads of mycelium, though these may coalesce and form rhizomorphs, which are sclerotized (toughened) tubes of hyphae that move resources like water and nutrients around the thallus. Dense mycelial fans can also be found under the bark of some affected trees. And most of it is underground, or hidden under bark. Thus, while invisibility comes in being hidden below ground, and also in being microscopic. And in a third sense it is invisible. In being so large that the eye could not see the entire limit of its body from a single vantage point.

However, the fungal record for largest and oldest living thing, being only the first one to surface, did not last. A 600 hectare thallus was identified in Washington state, and an Armillaria ostoyae thallus in the Blue Mountains of eastern Oregon was ascertained to cover 965 hectares, or about 2,385 acres, and could be as old as 8,650 years. As far as I know, this is the current record holder for Armillaria thalli.

I don't know if I'll make it to the festival in Michigan. It does look like a lot of fun. (I will not type "-gi" next to that, I will not. Because that would be totally corny). Cribbage Tournament!

New rare fungus discovered in England

Multiclavula vernalis (Basidiomycota, Cantharellales, Clavulaceae) was recently discovered and confirmed in England. This fungus is rare, and while reported from more northerly parts of the British Isles, this is a first report for England proper. The genus is odd in that it's members are frequently mycobionts (the fungal partners in lichens) in basidiolichens . The vast majority of lichenized fungi are ascomycetes.

The fruiting body (like most true clavariaceous fungi) is like a fleshy tube. Coral fungi, though similar in morphology, are not closely related, but are considered allied in the "clavarioid" fungi.

Trip to the Netherlands

I just got back from a trip to the Netherlands and Belgium, accompanying my wife to one of her professional meetings. Before going I made plans to meet up with some professional contacts of my own. Fortunately, I did get to see Prof. Duur Aanen at Wageningen, and unfortunately I did not get to drop in at CBS to visit with Dr. Pedro Crous. By Friday, I was pretty wiped out from my travels and didn't feel up to getting on another train.

We stayed in Maastricht, in the Limburg region of the Netherlands, and it was quite nice. I got to eat plenty of the 'white gold of Limburg', which is their white asparagus. Though it looks like an achlorophyllous plant, the white color is achieved by etiolation, or deprivation of light. Soil is mounded up around the emerging stalks which then do not produce chlorophyll, yielding stalks that are tender and milder in flavor. Etiolation is part of the process used to produce enoki mushrooms from Flammulina velutipes. I once isolated from a F. velutipes sporocarp (mushroom), which grew in culture but not very happily. It actually produced tiny little mushrooms on the Petri plate, as if to say, "Get me the heck out of here!".

But I did get to meet with Duur Aanen, which was a great pleasure. One of his research foci has been fungus-farming termites. I got to help his students on some mound excavation when I was doing dissertation research in South Africa. I got to see his lab at Wageningen, and chat with some of his students.

Know Your Mushrooms, my review

I finally got to see "Know Your Mushrooms" (2008), the documentary by director Ron Mann. I've blogged about this movie a couple of times before, how it was being made, how it features music by the Flaming Lips.

The film was shot primarily at the Telluride Mushroom Festival in Colorado, and features Larry Evans, a mycophile and "mushroom gypsy". Also featured is Gary Lincoff, who is the technical consultant on the film. They go on a foray, give lectures, and even have a mushroom parade.
The film explains and expands upon many of the common ideas about mushrooms. The most common mushrooms (Agaricus bisporus), mushrooms as sources of hallucinogenic substances, wild mushrooms as edible and choice vs. poisonous and toxic.

The film features several quick quizzes including questions about the Humongous Fungus, and some old timey footage from documentaries and other sources as well. And snippets of interviews and talks with mycophiles including composer John Cage, physician Dr. Andrew Weil and Terence McKenna

Also, there is some speculation about the role of psychedelic mushrooms in driving human evolution, the importance of mycorrhizal fungi, and the potential for mycoremediation and mycomedicinals .

At the end, there is a message. "End Fungiphobia now". I highly recommend this film for anyone who cares enough about fungi to have read to this point. While there was little new information for a big myco-nerd like me, the material is accurate, and presents an excellent introduction to the world of fleshy sporocarps.

Cedar quince rust

Yesterday it rained, which was greatly needed to take some of the yellow out of the air. The pollen has been off the charts. I took my car to the car wash and a few hours later it was dusty yellow again. But another effect of the cool, wet conditions was the fruiting of this fungus on our small juniper trees. At least I think they're junipers, definitely Cupressaceae. Yesterday the fruitings of this fungus looked slimy, like this...
and this...

But today, they've dried up and look more like this...
And this...
What is this strange orange ooze? Spoiler alert! It's in the title of this post. Cedar quince rust is in the same genus of rusts as apple cedar rust, Gymnosporangium. And like G. juniperi-virginianae and most species in the genus they are heteroecious (requiring two hosts to complete the life cycle) and demicyclic (lacking a uredinial stage). The hosts are in the Cupressaceae and Rosaceae. But clearly this is not cedar-apple rust. The telia of G. juniperi-virginianae are formed out of gall-like growths on the stems. When conditions are right, the telial horns project out of orifices, kind of like the eyes and ears of a stress-doll.

THAT up there is cedar apple rust

Cedar-quince rust, on the other hand, isn't associated with complex galls like cedar-apple rust, though it may cause branch swellings and flaky bark. It's the most important Gymnosporangium rust on the rosaceous hosts, quinces and others, according to Sinclair et al. I can't seem to find my newer version right now, oh wait, there it is! The causal fungus is G. clavipes, and it infects far more than just quince, including more than 480 rosaceous species in 11 genera (again, according to Sinclair and Lyon)! As you can see from the photos above, the smaller juniper branches are killed by the fungus, though the basal infections don't appear to be killing the tree in any hurry.

I just went out to check on my cedar apple rust gall on the juniper in my front yard, and it's gone! I thought I'd see if it fruited after yesterday's rain, but it's no longer there. I guess I never posted pictures of it either. They were a little blurry. But I do see some more small infections of G. clavipes on the big tree in the front yard. And here's a link to an even better photo of a G. clavipes infection, as well.

Phyllotopsis nidulans

Just got out in the woods yesterday. Probably my last time at this site over near Tuscaloosa. I came upon these lovely orange babies on a snag.
They look superficially like oysters, but on pine? No, these are the orange mock oyster, Phyllotopsis nidulans. Astipitate (without a stipe or stalk), on wood, these ones didn't smell fetid to me though they are reported to be nasty smelling. The pileus is fluffy in appearance on the top.


I just recently discovered another mycoblog, Mycorant. They have a link to my blog (thanks!) and do have some of the same material (i.e. fungal news), but a lot more of it. Did they get the inspiration for the name from looking upon my blog? Maybe. I'd like to think that imitation is the sincerest form of flattery. I recommend checking it out.

Jack O'Lantern Mushrooms


My eye was drawn to these babies as I was driving around town this afternoon. I do believe what we have here is jack o lantern mushrooms (Omphalotus sp.). They are common at the base of oak trees or on adjacent roots (as these were). These ones were really bright orange, so they stood out and I just had to stop and tiptoe across a bit of lawn to get these pics.
I've had a friend mistake these for chanterelles, as they do have decurrent gills, but fortunately she didn't eat them, as they are poisonous. Probably won't kill you, but you won't be happy for a while if you do try eating them.

Montana!

So, if you've visited my blog from stem to stern, you've seen the map of all the states I've visited. It's only there to shamelessly burnish my own glory, I admit. Well, right now I'm in Montana, which means I've added a state to my life list, leaving only Alaska, Delaware, Missouri, North Dakota, and South Dakota. I may have visited Delaware and not remembered it.

I'm planning on starting a post-doc out here in January, at least part-timing between Montana and Alabama, since I've got some roots in Alabama the Beautiful.

Here's a pic taken in Alabama by a friend of mine. I wish I could've seen this in person. That does appear to be a Hericium (coralloides or ramosum?), which is edible and choice.

Lots of interesting stuff out there....

I've been remiss in my blogging, especially so since there are SO MANY FUNGI fruiting out there, with all the rain we've been having. I recently went out with a friend to Tuskegee National Forest, where we saw a ton of stuff. And just about everywhere you look in the loveliest village on the plains, you see fairy rings.
Here's one.
And another.
And another.
And yet another. Really, these things are EVERYWHERE. I've blogged about them before, like in my neighbor's yard (UPDATE: she moved away! The new neighbors do not appear to be so mycophobic).

Today I was out in the woods near Tuscaloosa, and saw some fine fungi out there. I'm most jazzed about the gilled bolete I found, Phylloporus rhodoxanthus (sensu lato). I knew of its existence, and I can't remember if I'd ever found one before, but I saw the cap from above (being taller than most mushrooms) and thought "Aha, bolete!"

Turning it over, I was quite pleasantly surprised to find this:
It reminded me of a time (in California) when I picked up a Douglas-fir cone with a mushroom growing out of it, which I thought was Strobiluris trullisatus, and was surprised to find teeth (it was Auriscalpium vulgare). This mushroom looks just like a gilled mushroom (or "agaric") only with a bright yellow hymenium like a bolete. This particular one did not stain blue, which can happen, but does have forked gills (click on photo to zoom in), like a transitional form between true gills and the poroid (actually tuboid, boletes have tubes, not pores).
Also on the topic of boletes, I found some nice specimens of Strobilomyces dryophilus, "old man of the woods", good enough to eat, which I just might do!

Russula in my backyard

This photo and the following two are of a mushroom I found in my backyard. It's a Russula sp. How do I know? Well, for one, the bright white gills which reflect the white spore print. Okay, that's not a great character because gill color often doesn't betray spore print color. But the next clue is the crisp break in the stalk. This is a giveaway for the Russulaceae, and is caused by distinctive boxy shaped cells called sphaerocysts. The two main genera in the Russulaceae are Russula and Lactarius. Lactarius spp, as the name suggests, exude a milky secretion when the cap or stem are broken. So that leaves us with Russula. Which Russula? I don't know. There are no distinctively green capped Russula spp. in Bessette et al. Some Russulaceae are edible and choice, others not so much and could hurt you.

Lots of material for bawdy jokes in this one.

The stinkhorns are a group of mushrooms that are even more phallic than most mushrooms, and include a genus, Phallus. There's a new species of Phallus to be described in the next Mycologia from Sao Tome and Principe. It is to be named after the expedition leader, a herpetologist

Boletes

Found some more boletes. I think I'm ready to try some. They look like
B. hortonii But I'll drop some ammonia ok just to be sure. Also looks
like some are being parasitized by Hypomyces (white stuff)

A-looky heeyah!

I was walking out of the lab today and came across this bright orange something. It turned out to be a chanterelle, the first I've seen in Alabama. All this late wet weather we've been having has brought out all kinds of strange things.

This one is most likely either Cantharellus confluens or C. lateritius. Bessette et al. have pictures of both but indicate that they may be a single species. The folds are not well developed, so they don't look very much like gills, as chanterelles are not directly related to gilled mushrooms in the strict sense. Chanterelles are some of the more 'easily identified' mushrooms, but as always, that's a relative term.

So what did I do? I said I wasn't going to eat it, because it looked a little beat up, but the more I looked at it and the more certain I became of my ID, the more it seemed to be crying out for some brushing off, chopping, and frying in Amish butter. So that's what I did. Just brush off the dirt (soggy mushrooms aren't very nice), chop, fry in butter with a pinch of salt. Dee-licious!

I'd almost forgotten how delicious fresh wild mushrooms can be. What a treat!

Cornell University to return fungal collection to China

In 1937, as the Japanese invaded China during World War II, a Chinese mycologist, educated in the United States, packed up some of the most prized specimens from a national botanic institute in Nanking. He loaded them on oxcarts and had them smuggled them out of the country to his alma mater in the 'States, Cornell University.

Now, these specimens are being repatriated including the rare Lentinus tigrinus, pictured above. (a local species of Lentinus is pictured in the masthead). A neat story you can read all about here. And here's a nice quote about the specimens from Cornell's Herbarium Director Kathie Hodge "To an average person, they look like something you would sweep off your kitchen floor. But under the microscope they're beautiful and exciting and incredibly diverse." How very true.

But of course, because the story is about fungi, it's filed under STRANGE (sigh).

March is Maitake Mushroom Month

From the "now you tell me department". Still a little bit of the Maitake Mushroom Month left, so go and get you some! I haven't had maitake in a long while. I've never seen them around Auburn, but I'm sure you can get them in Atlanta. I had some friends who used to grow maitake and other less well know cultivatable edibles out in California. Maitake is Japanese for the dancing mushroom, because finding this fungus fruiting led the finder to dance with joy. This mushroom can be found growing in the wilds of the Northeast and out to Idaho, according to Wikipedia.

Okay, a recipe

Most of the what I get from Google news alerts are recipes. Not that I'm opposed to mycophagy, I just don't like posting lots of recipes that I haven't tried making or eating. But this one happens to be from Alabama, so I'll make an exception.

Paul Stamets says Fungi can save the world

Here's an interesting TED lecture (warning, 18 minutes long) by Paul Stamets, which outlines several ways in which fungi are very, very cool. He shows how fungi can bioremediate toxic spills, provide anti-viral pharmaceuticals, control pest insects, produce ethanol, and solve world hunger. See for yourself:



Thanks to my good buddy Dave for forwarding this along to me!

Otzi's fungi

Here's an article about a copper age mummy, Otzi, who died 5000 years ago in Europe, and happened to be carrying a few sporocarps about with him. The article refers to them as 'mushrooms', which irks me a bit, because they're conks, not really mushrooms. Mushrooms are really more fleshy, conks woody. But it's understandable given the level of myco-literacy among the laity. I once joked that I though mycology should be taught in the third grade. Probably not, but then it would be nice if mycologists had more company, I think.
