Species Information
Summary:
Features include 1) flat growth on wood with the pore surface exposed, 2) an ocher-whitish to pink to reddish orange or violet pore surface (quickly turning pink when handled), that starts development with isolated crater-like cups, 3) a narrow margin that is white to pinkish tan or purplish and webby or floccose, and 4) microscopic characters including large hyphae with whorled branching and occasional clamp connections.
Microscopic:
spores 3.5-5 x 1.5-2 microns, oblong to short-cylindric, smooth, inamyloid, colorless; basidia 4-spored, 14-16 x 4-6 microns, clavate, simple-septate at base; cystidia none; hyphal system monomitic, subicular hyphae 5-15 microns wide, colorless, thin-walled to slightly thick-walled, "mostly simple-septate, slightly swollen at the septa and frequently with whorled branching, rarely with single, double, or multiple clamps", tramal hyphae 3-4.5 microns wide, simple septate, (Gilbertson), 3.5-4.5 x 2-2.5 microns, elliptic to cylindric, sometimes slightly curved, smooth, inamyloid, colorless, with or without droplets, (Breitenbach)
Spore Deposit:
white (Buczacki)
Notes:

Habitat and Range
SIMILAR SPECIES
Ceriporia viridans is "presumed to be a synonym by some authors, in its typical form 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"). Porothelium fimbriatum is reminiscent because of development from isolated pores, (Breitenbach). See also SIMILAR section of Ceriporia purpurea, Ceriporia reticulata, and Porotheleum fimbriatum.Habitat
annual, growing on dead hardwoods, rarely on conifers, causing a white rot, (Gilbertson), on the underside of dead conifers and hardwoods, (Breitenbach), fall (Buczacki)
