Perichaena chrysosperma

Abstract

Diagnostic features. The doughnut-shaped plasmodiocarps occasionally produced in moist chamber cultures, and the prominently spiny capillitium make P. chrysosperma particularly distinctive. The macroscopic characters of this species, however, vary widely, and this may result in confusion with atypical forms of P. corticalis (Batsch) Rostaf., P. vermicularis (Schwein.) Rostaf. and even Trichia contorta (Ditmar) Rostaf. It may be distinguished from these three species by the short, wider and occasionally branched plasmodiocarps, the darker colour, spiny capillitium and smaller spores.
