Habitat and Range
SIMILAR SPECIES
Ceriporia viridans is presumed to be a synonym of Ceriporia excelsa with its pores of variable color, by some authors: in its typical form C. viridans "is supposed to be greenish when dry and to have spores less than 2 microns wide" and has smaller pores that do not discolor when bruised, (Breitenbach who also observed that the initial stage was "reticulate-porose in C. viridans and bowl-shaped in C. excelsa")Habitat
annual, on hardwood, more rarely on conifer wood, mostly on rather rotten wood, causing white rot in hardwoods, (Gilbertson), summer to fall (Buczacki)
