Importance and distribution

Species of Bryosphaeria are lichenicolous or coprophilous and grow on gametophytic or sporophytic structures of bryophytes, muscicolous species, blighting mosses, and hepati(ci)colous species inhabiting liverworts (Hepaticae) (Dobbeler 1997). They are important in carbon and nutrient cycling and play an important ecological role in polar regions (Currah and Davey 2006). Bryosphaeria megaspora was reported to be pathogenic on Antarctic mosses (de Menezes et al. 2019). Bryosphaeria comprise nine morphological species but no sequence data is available. Species are distributed among nine hosts in Brachytheciaceae, Bryaceae, Dicranaceae, Distichiaceae, Hylocomiaceae, Hypnaceae, Pottiaceae, Metzgeriaceae and Mniaceae. Bryosphaeria is reported mainly from cold regions such as Antarctica and Europe (Austria, former Yugoslavia, France, Romania and Sweden).
