Now and again, a supportive fan of the 1001 Mushroom Project will offer up some of their mushrooms for me to eat and blog about. Because I want to go through the whole process myself (finding, identifying, preparing, and eating a new species), I almost always decline their generous donations, But when a mushroom hunter shared with me photos of these gorgeous lilac "chanterelles", Gomphus clavatus, and asked if I'd like them for eating – they'd collected them before but weren't a big fan, or eating any mushroom for that matter – how could I say no?
ACTION ITEM: Sign a petition in support of students who want to change the name of the Entomological Society of America's annual competition, the Linnaean Games, and read their open letter to the ESA board on why it is necessary to do so. The text below offers further encouragment and background information, which is certainly relevant to mycologists as well.
Carl Linnaeus is one of many white historical figures whose legacy has been warped over time to hide away problematic aspects. We learn about Linnaeus at a very early age as the inventor of Latin binomials, a system of naming living organisms that is now highly encoded and regulated process for all life forms, including fungi. But what we don't learn about in school is his deeply racist beliefs of white supremacy, which were preserved in his scientific writings as an ordination of human races and ascription of pejorative moral and behavioral qualities to non-white people. It's awful stuff. As Linnaeus is the father of taxonomy, he is equally the father of scientific racism.

This magnificent and exceptionally delicious mushroom is universally regarded as rare. While mushroom hunters may never see Polyporus umbellatus, if you do find it, you will be able to come back year after year to the same location for a new harvest. P. umbellatus grows from the ground as a parasite and saprobe of the roots of hardwood trees. It appears from May to October (spring and fall, but typically not summer) across North America, growing as a fractal rosette of umbrella-shaped fronds. For some people, the mushroom has less appeal than what is going on in the soil. Over many years perhaps, P. umbellatus forms a large subterranean mass called a sclerotioum. Sclerotia are hard resting structures capable of longterm dormancy for survival in drought and cold. Some sclerotia are small like seeds and others are as big as basketballs. In the case of P. umbellatus, the sclerotia can be enormous, more than a foot in diameter, with a solid, corky interior and black rind. In traditional Chinese medicine, the sclerotium of P. umbellatus goes by the name Zhu Ling and is taken for a number of purposes, in particular as a diuretic (to stimulate urination).

Laetiporus sulphureus is a magnificent mushroom, easily identifiable by its bright yellow pore surface and overlapping, shelf-like growth on the standing or fallen trunks of hardwoods. It might just be my all-time favorite mushroom. The young mushrooms check all the boxes of a great wild edible:
That's right, if you find a mega flush, there will likely be more chicken than you can eat yourself and others will be eager to buy it from you. In Ann Arbor, chicken of the woods fetches about $16 a pound. The flush documented here, which I found when the mushrooms were just starting to bubble out of a large downed trunk, yielded about 50 pounds of tender chicken over the span of a week.
MycoBank Taxonomy: Fungi, Dikarya, Basidiomycota, Agaricomycotina, Agaricomycetes, Polyporales, Polyporaceae, Noefavolus
Mushrooms resembling Neofavolus alveolaris are common and widespread across eastern North America in the spring. They can persist through the summer, fall, and even into the winter, becoming hardened and bleached over time. Despite the common name, the pores are rarely perfectly hexagonal, instead usually vaguely and irregularly polygonal. Regardless, the hairy/scaly orange cap and large, elongated pores make this mushroom easily recognizable – that is, if we actually knew what we were identifying. Neofavolus alveolaris includes a number of cryptic species, which may not be all that suprising given that name has been applied to similar mushrooms occurring in temperate and boreal areas across the entire Northern Hemisphere (Sotome et al. 2013).

Coprinellus truncorum (or more commonly referred to as C. micaceus - more about that later) is an inky cap, which means before you know it, the mushroom will enzymatically digest itself in a soppy process called deliquescence. Inky caps are really the milquetoasts of the mushroom world, turning into complete mush soon after fruiting. Deliquescence is much more than feebleness, though. It is a process of spore dispersal that has evolved independently in multiple lineages of mushrooms. Deliquescence starts at the edge of the cap and moves towards the stem. Meanwhile, the spores mature in the same pattern, but one step ahead of the destructive enzymes. As a result, mature spores are always at the edge of the dissolving cap - a perfect position to catch air currents for dispersal. If you are interested in learning more about inky caps and their taxonomy, check out Michael Kuo's page on the topic.
For Michigan and much of the upper Midwest and Northeast, May marks the beginning of the six-month mushroom-hunting season and is heralded by a unique cast of tasty fungi. I recently received an email from the Michigan Mushroom Hunter's Club that listed the 26 species of common macrofungi that can be found in May. This list comes from a 1986 article by Walt Sturgeon entitled "May in Michigan Means Morels and More", which is what my alliterative header pays homage to. I wanted to share the list here, both as a phenological resource as well as a reference of edibility. The names are updated to reflect current taxonomy:

I bemoan the appearance of this beautiful mushroom. The colors of the cap are wildly variable, ranging from ochre to olive-brown to steely blue-grey. It's subtended by a cute stumpy stem that is sometimes freckled. The gills are close and have an orangey-yellow color. So why does it bring me sadness? I divide my year in half: six exuberant months of mushrooms and six horrid ones of frigid temperatures, denuded vegetation, and dormant fungi. True to its name, the late fall oyster signifies the end of the mushroom season and the beginning of the long winter hibernation. In the Great Lakes region, you can find Sarcomyxa serotina growing from hardwood logs in late October and November. And, sorry to say it, there won't really be any edible mushrooms popping up again until the end of May.
Mycobank Taxonomy: Fungi, Dikarya, Basidiomycota, Agaricomycotina, Agaricomycetes, Agaricales, Agaricaceae, Lycoperdon
In my opinion, unlike the giant puffball, Lycoperdon pyriforme is actually a good mushroom, even if the translation of its Latin binomial - pear-shaped wolf fart - doesn't suggest it. When young, it looks like a well-behaved toasted marshmallow with a uniform brown color on the outside and white flesh on the inside. As it matures, the entire inside is converted into spores, a tear forms on the top, and the mushroom, well, farts spores when it is impacted by raindrops, falling twigs, or other objects. L. pyriforme makes up for it’s relatively diminutive size and unfortunate Latin name by growing in large clusters on decaying hardwood and conifer stumps and logs, hence its common name: the stump puffball. Its pear-like shape, extensive white rhizomorphs, and growth on wood - a somewhat rare habit for puffballs - make this mushroom fairly unmistakeable.

Some fungi are "rare" simply because they are obscure and nobody besides myconerds looks for them. P. aurantiorugosis, on the other hand, is a gorgeous, photogenic mushroom. Despite the fact it stands out, it is seldom documented, and thus can be regarded as truly rare. For example, Michael Kuo from mushroomexpert.com has only found it once in 20 years of mushroom hunting.
I am continuously surprised by the forest behind my house. It's a cruddy place - buckthorn, honeysuckle, and box elder run the woods; trash is scattered about or heaped into dumpy piles; and invasive fungal pathogens are devastating the hardwood trees. Yet, it is full of treasures. In addition to the truffle I recently found, it is also where I discovered this mushroom. The scarlet-red fruiting bodies were growing off the end of a fallen, decorticated trunk. I puzzled over them for a long time. They were so distinct yet they didn't fit any description in my head. Once I noticed the free, pinkish gills, I knew it was a Pluteus species and identification was only a quick Google search away. To my surprise, this was the first documented encounter of P. aurantiorugosis in Michigan since the 1970s!
Mycobank Taxonomy: Fungi, Dikarya, Basidiomycota, Agaricomycotina, Agaricomycetes, Agaricales, Agaricaceae, Calvatia
Calvatia gigantea is not a good mushroom. It can be so huge, such a massive marshmallow, that I want so badly for it to be tasty. I’ve baked it as pizza crust, sautéed it, and deep fried it as puffball parmesan, but it’s never good. The smaller the ratio of puffball to other things (fried bits, sauce, veggies) the better. I’m no mathematician, but I think if you take that property to it’s limit, the best puffball dish is one that does not contain any puffball at all. In my opinion, this mushroom smells and tastes chemically, like a permanent marker. Chalk it up to bad cooking or subpar specimens, but I would argue that I’m a pretty good cook and that I’ve selected the finest, youngest, whitest, firmest, maggotless puffballs around, but Calvatia gigantea still makes good food taste bad. It’s not a good mushroom.

I did it! I’ve eaten 1001 different mushrooms! What, you thought my goal was to eat “one thousand and one” mushrooms? That’s absurd! Isn’t everything binary in this age of computers?
To celebrate the accomplishment of the binary version of this project (1001 = 9), I endeavored into the exquisitely funky world of truffles. While some people make the distinction between “true truffles” (Tuber spp.) and “false truffles” (everything else that grows underground), I’ll refer to them all as truffles. Recently, I learned that truffles are all around us. There are actually over 40 Tuber species native to North America (Guevara et al. 2013 listed 38, and more have been described since) and if you consider underground fungi in other genera, there might be hundreds of species present in the United States!
Mycobank Taxonomy: Fungi, Dikarya, Basidiomycota, Agaricomycotina, Agaricomycetes, Russulales, Hericiaceae, Hericium
This magnificent mushroom was growing right off a busy path in the woods. I watched it for days hoping it would grow bigger but not get snatched up by somebody else. Finally, it was ready (and I actually had time to harvest and cook it). Unlike more familiar edible mushrooms with gills or pores, Hericium coralloides has icicle-like spines, or teeth, similar to hedgehog mushrooms (Hydnum spp.). We might be inclined to lump these toothed mushrooms together into the same group, but spines are not a trait indicating shared ancestry. Rather, spines convergently involved in very distantly related taxonomic groups – in this case, Hericium in Russulales and Hydnum in Cantharellales – to achieve a similar mechanism of spore dispersal.
Mycobank Taxonomy: Fungi, Dikarya, Basidiomycota, Agaricomycotina, Agaricomycetes, Boletales, Suillaceae, Suillus
If Suillus species were placed under the Hogwarts sorting hat, most would be sorted into Slytherin. They are slimy and downright no good. Suillus ampliporus, on the other hand, would be sorted into Gryffindor because of its firm constitution. It was a pleasure to meet the this noble mushroom in the mossy boglands of northern Michigan. Also known as the larch bolete, S. ampliporus prefers soggy lowlands where it associates as a mycorrhizal fungus with tamarack (Larix laricina). Highlighted by the late afternoon sunshine on the first day of fall, these boletes greeted me in great numbers.
Mycobank Taxonomy: Fungi, Dikarya, Ascomycota, Pezizomycotina, Pezizomycetes, Pezizales, Morchellaceae, Morchella
Morels are one of the most sought-after fungi across the world. They are delicious and – for the most part – defy cultivation. Morchella taxonomy and ecology have long been active fields of mycological research, clarified in part by DNA studies, but a long way off from being fully understood. I am fascinated by their ecological dynamism, Morels seem to be saprotrophic, mycorrhizal, and endophytic, depending on the species and the lifecycle stage. Some species also have intimate relationships with fire. As a result, morels are found in an enormous range of habitats and most statements about ecology seem more like recommendations rather than definitive guidelines for how to find them. The same is true for morphology. In the past, species were defined by rigid dichotomies but now we know each species to exist as a probability cloud of various features in which a holistic view of a given specimen is required to determine the name that best applies. Identification is further aided by collecting locale as a good amount of regional endemism is involved in morel biogeography.
