Gloeosoma
Gloeosoma is a genus of crust fungi in the family Stereaceae (order Russulales). Species in this genus form thin, effused fruiting bodies that adhere tightly to their substrate, often appearing as smooth to slightly wrinkled crusts without a distinct cap or stipe. The genus is characterized by its smooth, hyaline spores and a hymenium that lacks cystidia. Gloeosoma species are saprotrophic, decomposing dead wood in forest ecosystems.
