Laeticutis cristata is a species of fungus that belongs to the family Fomitopsidaceae. It is a crust-forming fungus that grows on decaying wood, typically oak and other hardwoods. In East and Central Texas, Laeticutis cristata has been found in forests, particularly in areas with abundant oak trees, where it forms thin, effused crusts on logs and stumps. The fruiting bodies are resupinate, meaning they grow flat against the substrate, and have a smooth to slightly wrinkled surface that ranges in color from white to pale yellow or gray. Microscopic examination reveals cylindrical to club-shaped basidiospores that are 4-6 μm long. Laeticutis cristata is considered a saprotrophic fungus, playing a role in decomposing organic matter and recycling nutrients in the ecosystem.
