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).

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.

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 unknown truffle species 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!

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.

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.
Mycobank Taxonomy: Fungi, Dikarya, Ascomycota, Pezizomycotina, Pezizomycetes, Pezizales, Discinaceae, Gyromitra
Elephant ears mushroom is the most common Gyromitra species in Wisconsin. It grows as a saprotroph and possibly as a mycorrhizal fungus with oaks. You can find it fruiting during morel season along with other spring ascomycetes such as the scarlet cup fungus and devil's urn. These mushrooms can get huge, which is all the more reason to wonder, can I eat them? Confusion and uncertainty reigns about the edibility of this species and other Gyromitra mushrooms. In field guides, Gyromitra is universally labeled as poisonous, even deadly. However, other sources suggest a much more nuanced picture.

Finding devil's urn wasn't a problem until I was hunting for it. In the past I would stumble across large flushes of this mushroom and be intrigued by its bizarre look, but honestly I never considered eating it. Then I read about it in Michael Kuo's 100 Edible Mushrooms and was on the hunt. Suddenly, it wasn't so easy to find.

Things have been slow in the field. Right when it seems like there should be morels, it snows. No worries, our refrigerators and pantries are full of fungi. While most of these are molds that we don't want, Rhizopus oligosporus growing on soybeans is one that we do. Better known as tempeh, this Indonesian fermented food is almost more fungus than bean. The white mass holding the beans together is the mycelium of the fungus, which is composed of string-like cells called hyphae. The black spots are areas where R. oligosporus has sporulated. Black, white, and grey are all normal colors on tempeh – more colorful filamentous molds are not. Raw tempeh is edible but like all fungi it is best cooked. Cooking aids in digestion by breaking down chitin in the cell walls – the same substance found in the exoskeletons of arthropods. Would you want to eat a raw shrimp shell? Cook your mushrooms!

I wanted to start the 1001 Mushrooms Project on the right foot by eating a morel. However, it is fitting that Sarcoscypha dudleyi was my first. This is one of the very first mushrooms that fruit in the spring in northern United States. Seeing this red dollop on the forest floor is a little unbelievable after six months of white snow and brown plant debris. Furthermore, S. dudleyi represents the bizarre culinary possibilities of fungi as well as the strange mushrooms that will constitute a large portion of the 1001 mushrooms that I eat.
I divide up the mushrooms I eat into three simple categories of edibility: bad, good, and great. I do not seek out mushrooms that taste bad to me. I will not hesitate to collect mushrooms that I think are good. And mushrooms that are great - I am on the hunt! If the mushroom is poisonous or possibly poisonous, I will simply avoid eating it again unless enough evidence accumulates to suggest that mushroom is actually safe to eat, and I recommend you do the same.
