Species Information
Summary:
{See also Trametes versicolor and similar polypores Table.} Cerrena unicolor is easy to recognize because of the hirsute (coarsely hairy) cap, the black line in the flesh, and the labyrinthine pore surface. This species was identified as the fungal symbiont of the wood wasp Tremex columba on Fagus grandifolia in eastern Canada.
Microscopic:
spores 5-7 x 2.5-4 microns, cylindric-elliptic, smooth, inamyloid, colorless; basidia 4-spored, 20-25 x 5-6 microns, clavate, with basal clamp; cystidia 40-60 x 4-5 microns, hyphoid (not clearly differentiated from vegetative hyphae), thin-walled, with basal clamp; hyphal system trimitic: generative context hyphae 2-4 microns wide, thin-walled, nodose-septate, skeletal context hyphae 2.5-5 microns wide, thick-walled, aseptate, binding hyphae 2-4 microns wide, thick-walled, aseptate, much-branched, tramal hyphae similar, (Gilbertson), spores 5.5-7 x 3-3.5, elliptic, smooth, inamyloid, colorless, (Breitenbach)
