Type species – Montagnula infernalis (Niessl) Berl., Icon. fung. (Abellini) 2(2–3): 68 (1896).

Notes – Montagnula was introduced by Berlese (1896) to accommodate M. infernalis and M. gigantean. Based on the morphology and phylogeny, Ariyawansa (2014d) placed Montagnula in Didymosphaeriaceae. Montagnula species are characterized by globose or sphaerical, immersed ascomata with a clypeus, claviform asci, fusoid or ellipsoid ascospores with transverse septa and one or more longitudinal septa (Barr 1990a, Ariyawansa et al. 2014d). Wanasinghe et al. (2016b) transferred two Munkovalsaria species (M. appendiculata and M. donacina) based on phylogenetic analyses. Montagnula species play a vital role as saprobes growing on dead plants, especially dead wood and bark, sometimes on dead leaves (Ariyawansa et al. 2014d). A well-resolved revision of Montagnula is difficult since it lacks molecular data. Therefore, representative species of these Montagnula species need to be recollected and molecular data obtained for clarifying its phylogenetic affinity.
