asexual spores

The chlamydospores on the cap are formed by mitosis and are asexual, rather than being formed by meiosis like the basidiospores in a hymenium. thus there are no basidia on the cap or on the underside. therefore no hymenium. it’s a keen mushroom.

So, A. lycoperdoides has the shape of a “typical mushroom”, but the hymenium is on the pileus rather than where you would expect to find gills or pores??

Unless you’re the one being parasitized, of course…first saw this one in Pennsylvania at a NEMF foray; a nice sop for hunting in hundred degree weather. So very uncivilized. Give me the cool of a CA mushroom season any day…
