Kiebacher, T. & Meier, M. 2020. The generic placement of Grimmia teretinervis Limpr. – Herzogia 33: 544 –547.
Grimmia teretinervis is a dioicous moss of the Grimmiaceae that has never been found with sporophytes. Consequently, its generic placement is uncertain, and although it is mostly referred to Grimmia, some authors assign it to Schistidium. The phylogenetic analysis of the nuclear ITS region indicates that it is a species of Schistidium and that it is related to the likewise dioicous S. tenerum.
