Notes.

Microthecium brevirostrum , Mi. fallax and Mi. fimbriatum produce ostiolate ascomata and ellipsoidal to citriform, often plataniform, smooth-walled ascospores with an apiculate germ pore at each end. Microthecium fimbriatum is easily distinguished by its smaller (100-110 µm diam.), reddish ascomata, while Mi. fallax differs in the production of bulbils.
