Asterophora     Genus

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)

Amanita onustaWhite Spored     Suborder
Spore print "light-colored": white or buff, sometimes tinged with pink or tan. Greenish and (except for the Russulales) yellow spore prints also go here
Stalk fibrous, not fracturing like a piece of chalk

TricholomataceaeTricholomataceae     Family
None of the special features distinguishing the other white-spored genera:
Gills not free, as in the Lepiotas and Amanitas
Basidia not extra-long, as in the Hygrophoraceae
Spores smooth, except for Lentinellus

Asterophora parasiticaFungicolous Trich     Subfamily
Cap less than an inch across
Growing on other fungi, usually on their blackened and squishy remains

Asterophora     Genus     Ditmar: S. F. Gray

Asterophora parasitica


Microscropic Characters

Narrow down your identification:

Asterophora parasiticaAsterophora lycoperdoides
Resembling a puffball when young: gills usually contorted, thick
Entire fruiting body originally white or whitish
Cap becoming misshapen and covered with brown powder as its cells grow thick-walled and detach themselves from each other, becoming chlamydospores

Asterophora parasitica
Quite rare
Gills and stem well-developed, entire fruiting body white, silky
It is the gills here that disintegrate into chlamydospores, from the margin on up
Cap remains smooth, although it may darken to brownish-grey in age
