Diaporthomycetidae family incertae sedis, Papulosaceae, Fluminicola

Index Fungorum number: IF28031; 4 morphological species (Species Fungorum 2020), 3 species with sequence data.


Saprobic on wood in freshwater habitat. Sexual morph: subglobose to globose or ellipsoid, immersed to erumpent with neck protruding through host surface, black, solitary, coriaceous. Neck short, centrally or laterally positioned, brown to black, periphysate. Peridium multi-layered, consisting of brown-walled compressed cells. Paraphyses septate, hyaline, wider at the base, tapering towards the apex. Asci 8-spored, unitunicate, cylindrical, short pedicellate, comprising a J-, bipartite or discoid, apical apparatus. Ascospores uniseriate or overlapping uniseriate, hyaline, 3-septate, fusiform, smooth or verruculose, with or without cup-like, bipolar appendages. Asexual morph: Undetermined (adapted from Wong et al. 1999, Réblová et al. 2013, Zhang et al. 2017).


Type species: Fluminicola bipolaris S.W. Wong, K.D. Hyde & E.B.G. Jones, Fungal Diversity 2: 190 (1999)


Notes: Wong et al. (1999) introduced Fluminicola for the freshwater species F. bipolaris. Five species are accommodated in the genus, i.e. F. aquatica, F. bipolaris, F. coronata, F. saprophytica and F. thailandensis (Zhang et al. 2017, Index Fungorum 2021). Fluminicola coronata has, however, not been validly published (Index Fungorum 2021).
