Summary:
Features include flat growth on conifer wood with spore surface exposed, white to cream pore surface with a white margin, round to angular or slightly sinuous pores, 2-3 per millimeter on average, thin white flesh, and microscopic characters including finely asperulate amyloid spores, generative hyphae with clamp connections, dextrinoid skeletal hyphae, and rare gloeoplerous hyphae. The description is derived from Gilbertson(1).

Microscopic:
spores 5-6 x 4.5-5.5 microns, round, "finely asperulate", amyloid, colorless; basidia 4-spored, 15-20 x 4-8 microns, clavate; cystidia and other sterile hymenial elements absent; hyphal system dimitic, generative hyphae 1-3 microns wide, with clamp connections, skeletal hyphae 1.5-3 microns wide, thick-walled to solid, strongly dextrinoid, gloeoplerous hyphae "rare and scattered, irregular and often with blunt side-branches, slightly yellowish when mounted in KOH, but negative in Melzer''s reagent", width variable, mostly 3-6 microns, but parts up to 15 microns wide

Notes:
Wrightoporia lenta has been found in BC, WA, ON, FL, GA, NY, and SC, and known as well "from Central and South America and Africa", (Gilbertson).
