Melanospora aculeata E.C. Hansen, Vidensk. Meddel. Dansk Naturhist. Foren. Kjobenhavn 59: 15. 1877.

Notes.

Cultures of this species are not available, but it was originally described as producing small asci (18-21 × 7-8 μm) and ascospores (4-6 × 3-4 μm). This species produced ostiolate ascomata without a neck, typical of Microthecium; however, such small ascospores have never been seen in Microthecium .
