Trechispora microspora is a corticioid fungus producing very small spores, as its name indicates. It grows as a thin, white to cream-colored crust on the underside of decaying hardwood and conifer logs in temperate and boreal forests. This saprotrophic fungus decomposes dead woody material, contributing to nutrient cycling in forest ecosystems.
