Myrmecridium Arzanlou, W. Gams & Crous, Stud. Mycol.58: 84 (2007)
Index Fungorum number: IF504559; 13 species with sequence data.
Type species – Myrmecridium schulzeri (Sacc.) Arzanlou, W. Gams & Crous
Notes – Myrmecridium accommodates ramichloridium-like taxa with hyaline mycelium and pale brown to hyaline, conidiogenous cells with pimple-like denticles. Among the 15 epithets listed in Index Fungorum (2020), M. montsegurinum is reported as a sexual morph in Myrmecridium (Réblová et al. 2016a) and the remaining 14 taxa are based on their asexual morphs. Because Myrmecridium sorbicola has septate conidia and it phylogenetically groups with species of Neomyrmecridium, it was transferred to the latter genus (Crous et al. 2018b). Myrmecridium montsegurinum, which is the only known sexual morph in Myrmecridium, occurs on decaying wood of various deciduous trees submerged in freshwater (Réblová et al. 2016a). Myrmecridium montsegurinum shares a close phylogenetic affinity to M. schulzeri and M. flexuosum, but statistical support for this alliance is not significant (Réblová et al. 2016a)
