Notes.

Lambert et al. (2019) introduced Hypomontagnella to accommodate H. monticulosa as the type species and included several species previously described under Hypoxylon . Hypomontagnella differs from Annulohypoxylon and Jackrogersella by smooth perispores or transversally striate ornamentations. Additionally, Hypomontagnella species are distinguished from Hypoxylon species by woody to carbonaceous stromata that lack colored granules ( Lambert et al. 2019). They have papillate ostioles, usually with black annulate discs, without apparent KOH-extractable pigments in mature stromata ( Lambert et al. 2019). The cultures of Hypomontagnella species produce sporothrolide-type strong antifungal polyketides. Species in this genus have been reported as saprobic or endophytic on plants ( Lambert et al. 2019). Six species are listed under Hypomontagnella in Hyde et al. (2024) and Index Fungorum (2025).
