Usually growing on bark and wood, sometimes on sawdust, earth,
fir-cones, stems of herbaceous plants, leaves, moss, etc. Some species
are phosphorescent. Young examples of some species of Corticium
may readily be confounded with Pezizm. The hymenium of some
species occasionally exhibits pale rose-coloured to deep crimson
stains caused by the presence of a parasitic mould, Hypomyces
rosellus. Species 1832—1866
