Орбилиевые - Orbiliaceae 9/27/25

The Orbiliaceae are a family of saprobic sac fungi. It is the only family in the monotypic class Orbiliomycetes and the monotypic order Orbiliales. The family was first described by John Axel Nannfeldt in 1932 and now contains 288 species in 12 genera. Members of this family have a widespread distribution, but are more prevalent in temperate regions. Some species in the Orbiliaceae are carnivorous fungi, and have evolved a number of specialized mechanisms to trap nematodes. Orbiliaceae do not have stromata, dense structural tissue that produces fruit bodies. They have small disc-shaped apothecia, that are typically convex, brightly colored or translucent. Their ascospores are small (typically less than 10 x 1 μm), hyaline, and have an oval or ellipsoidal shapeю Species are usually found in wood on both wet and dry habitats. Anamorph species are hyphomycetous.
