Notes.

Microthecium fimicola is characterized by ostiolate ascomata and coarsely reticulate ascospores with strongly apiculate germ pores at both ends. The other species with ostiolate ascomata and reticulate ascospores are Mi. internum and Mi. quadrangulatum . The main differences among them are the shape and size of the ascospores, being citriform in Mi. fimicola , spindle-shaped in Mi. internum and fusiform in Mi. quadrangulatum . The production of bulbils has only been observed in our fresh isolates of Mi. fimicola , although this was not previously reported.
