Minutoexcipula

Minutoexcipula is a genus of lichenicolous (lichen-dwelling) fungi of uncertain familial placement in the order Chaetothyriales.

The genus was circumscribed in 1994 by M. Violeta Atienza Tamarit and David Leslie Hawksworth, with Minutoexcipula tuckerae assigned as the type species.

The genus is characterized both by its black convex sporodochia-like conidiomata, as well as the well-differentiated exciple on these structures.

They appear as dark brown to black spots that are typically rounded, though they can occasionally be elongated or slightly irregular in shape.

Some species have a distinctive wall-like structure (exciple) around the edge, with the cells at the top often having unevenly thickened, darkly pigmented walls.
