Botryobasidium is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps (fruit bodies) are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution.
