stage only, on Stereum hirsutum and other leathery fungi.

in two places in the white plasmodium stage, looking rather like
bread-crumb, among bracken, grass and dead leaves. It matured
indoors in a tin box; as usual when the plasmodium of this
species and also of F. septica matures in a still moist atmosphere,

form a number of small aethalia, some of them hardly more than
curved plasmodiocarps.

grass.
