From 1-2 in. across, often irregular, furnished with a mass 
of mycelium forming a branched rooting base. Recognised 
by the thin peridium, olive-brown spores, and yellow trama, 
which becomes floccose, and persists as an imperfect capil- 
litium consisting of septate threads with clamp-connections.

peridium thick, almost smooth, splitting in a stellate manner
