Notes – Lambert et al. (2019) erected Hypomontagnella to accommodate several species previously described as Hypoxylon species. Hypomontagnella differs from Annulohypoxylon and Jackrogersella by smooth perispores or with transversally striate ornamentations. It differs from species of Hypoxylon in having woody to carbonaceous stromata lacking coloured granules, papillate ostioles usually with a black annulate disc, and without apparent KOH-extractable pigments in mature stromata (Lambert et al. 2019). Cultures of all Hypomontagnella species studied so far produce the strongly antifungal polyketides of the sporothrolide type, which have never been found in any other species of Xylariales and are otherwise only known from spurious endophytes.
Type species: Hypomontagnella monticulosa (Mont.) Sir, L. Wendt & C. Lamb., in Lambert, Wendt, Hladki, Stadler & Sir, Mycol. Progr. 18(1-2): 190 (2019).
Other accepted species: Species Fungorum – search Hypomontagnella.
