Microthecium japonicum is a species of fungus in the family Ceratostomataceae.[2] It was first described as a new species in 1986, as Persiciospora japonica. The species epithet refers to Japan, where the type specimen was collected in 1975.[3] It was reclassified in Microthecium in 2018.[4]
It is distinguished by its ostiolate ascomata (fruiting bodies with a small pore-like opening) and ellipsoid to spindle-shaped (fusiform) ascospores with a pitted, net-like surface pattern. It resembles M. moureai in these general features, but differs in producing a phialidic asexual form and small bulbil-like propagules, which are absent in M. moureai. The spore surface in M. japonicum is also more finely reticulate, whereas M. moureai has a coarser reticulation.[4]
