Summary:
Features include flat growth on wood with the pore surface exposed, the color cream to light buff or pale straw-colored when dry, small angular pores, leathery texture, an associated white saprot, and microscopic characters including small spores. The description is derived from Gilbertson(1).
Antrodiella romellii has been found in BC, WA, OR, ID, AB, AZ, CO, MN, and MT, (Gilbertson).
Cap:
growing flat on wood with pores exposed, in small to confluent patches, up to 0.4cm thick, leathery, dense and hard when dry and semitranslucent in section as if partly soaked in an almost colorless resinous substance
Flesh:
up to 0.1cm thick; white
Pores:
6-8 per mm, angular, some may become larger when dry; "cream to light buff or pale straw-colored when dry"; tube layer up to 0.2cm thick, colored as pore surface
Microscopic:
spores 3.5-4 x 2-2.5 microns, oblong-elliptic to short cylindric, smooth, thin-walled, inamyloid; basidia 4-spored, 9-15 x 3-5 microns, clavate, with basal clamp; cystidia not present although hyphal pegs may occur; hyphal system dimitic or trimitic: generative hyphae 2-3 microns wide, thin-walled, clamped, skeletal hyphae 2-4 microns wide, colorless, thick-walled, also some slightly more branched hyphae of even thickness 1.5-3 microns wide that may be interpreted as binding hyphae
