: Bryostigma muscigenum.

Bryostigma muscigenum is a species growing over mosses, bark and even rock. It is characterized by minute, distinctly convex, black apothecia growing on a scurfy-granular thallus with a chlorococcoid photobiont. The colorless spores are 1-septate. It is difficult to distinguish from similar species without microscopical examination.
