Species Information
Summary:
Features include perennial flat growth on wood, a white to cream pore surface, white crumbly tissue under the tubes, relatively broad spores, cystidioles, and often oily to resinous irregular globules in microscopic preparation. The description is derived from Gilbertson(1).
Taste:
bitter
Microscopic:
spores 4.5-7 x 2.5-3.5 microns, broadly cylindric to oblong elliptic, inamyloid, colorless; basidia 4-spored, "15-10 x 5-7" microns [sic], clavate; cystidia none, but fusoid, non-projecting cystidioles up to 18 microns long usually abundant among the basidia, colorless to weakly yellowish; hyphal system dimitic, generative hyphae, 2-5 microns wide, thin-walled, with clamp connections, skeletal hyphae 3-5 microns wide, thick-walled to solid, sinuous, unbranched to occasionally dichotomously branched, inamyloid, microscopic preparations often filled with oily to resinous irregular globules, (Gilbertson), microscopic preparations of fruitbody tissues "often contain numerous oily globules" (Ginns)
Notes:
Resinoporia crassa is known from BC (Ginns(28)), and WA, ON, AK, MI, MT, NY, OH, PA, WI, and the inner parts of North and Central Europe, (Gilbertson(1))
Habitat and Range
SIMILAR SPECIES
Resinoporia sitchensis has a similar stratified fruitbody and may have resinous irregular bodies microscopically, but spores are narrower, cystidioles have a prolonged neck rather than being ventricose, and weakly dextrinoid hyphae are present in masses, (Gilbertson), Resinoporia sordida has a similar stratified fruitbody and may have resinous irregular bodies microscopically, but spores narrower, cystidioles absent or very rare, and weakly dextrinoid hyphae present in masses, (Gilbertson), R. sordida also has oily globules, but spores are narrower and skeletal hyphae have weakly amyloid walls, (Ginns).Habitat
perennial, on conifer wood, causes a brown rot
