April 1st, Cornocybe nuttalliiodes The weird and distinctive fruiting bodies of this odd-ball are distinctive, although it is rarely found or identified by mushroom hunters. The taxonomy of this, like many fungi is in flux, It was originally called (but never officially published as) Inocybe boletinoides. It resembles Inocybe strobilomyces from the top, and is said to have spores that are amygdaliform, smooth, brown and similar Pleurocystidia; fusoid, thick-walled only near apex, brown, rarely crystals encrusted, scattered. kaimaibush.co.nz/Fungi/Inocybe%20strobilomyces.html However, as you can see, this lacks gills, but the argument was made that is was similar growth pattern to Lentinus tigrinus f. secotioides, which is a secotioid form of a gilled mushroom. mushroomobserver.org/observer/observation_search?pattern=Lentinus+tigrinus+f.+secotioides Thats when genetics came into play. Recent sequences have shown that it isnt even remotely related to Inocybe, and now has been placed into the new genus Cornocybe; (which I believe means hard head after its dense cap flesh). The proposed species name is nuttalliiodes, because it resembles the acorn caps of Nuttall Oak, Quercus nuttallii. It apparently is widespread through the Sierra and Cascade Mountains of CA and the PNW, occurring in the fall. The same researchers have found a spring fruiting species that is not yet described, with a tighter inrolled margin to the cap, and spores born on the cap surface, similar to Asterophora lycoperdoides. mushroomobserver.org/observer/observation_search?pattern=Asterophora+lycoperdoides It also has a parasite that forms a red growth on the cap, (think Lobster Mushroom that just covers the cap).
