Notes.
This species produces non-ostiolate ascomata and citriform, smooth-walled ascospores. Other species previously placed in Melanospora characterized by the production of non-ostiolate ascomata and smooth-walled ascospores are Mi. hypomyces , Mi. levitum and Mi. zobelii . Microthecium hypomyces is distinguished by its fusiform ascospores (citriform in the other species), and Mi. levitum by the presence of bulbils and a phialidic asexual morph. Microthecium geoporae and Mi. zobelii are distinguished by the size of their ascospores [28-30 × 12 –13(– 15) µm in Mi. geoporae and 18-25 × 8.5-12 × 6-9 µm in Mi. zobelii ]. Microthecium tenuissimum shows similar morphological features to these species but its ascospores are finely reticulate under SEM and its ascomata are smaller (less than 120 µm) than in the other species.
