Type speciesNemania serpens (Pers.) Gray

NotesNemania is a species rich and well-established genus in Xylariaceae (Daranagama et al. 2018, Wendt et al. 2018) characterized by stromata not associated with bark rupturing structures, lack KOH-extractable pigments and finely papillate ostioles. Maharachchikumbura et al. (2016b) and Réblová et al. (2016b) proposed the use of Nemania over Geniculosporium following Stadler et al. (2013). Nemania bipapillata is illustrated in this paper (Fig. 267).
