Citation when using this data: Dong W et al. 2020 – Fungalpedia, Ascomycota.

Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig. 1

Classification: Torulaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on submerged wood. Sexual morph: Undetermined. Asexual morph: Colonies on the substratum superficial, effuse, gregarious, hairy, dark brown. Mycelium immersed, composed of septate, branched, thin-walled, smooth, pale brown hyphae. Conidiophores macronematous, mononematous, erect, cylindrical, usually with short branches near the apex, straight or flexuous, dark brown, septate, smooth. Conidiogenous cells tretic, with a distinct pore, integrated, terminal, doliiform or lageniform, subhyaline to pale brown. Conidia acrogenous, in branched chains, dry, clavate to subcylindrical, straight, pale green to brown, septate, verruculose, thin-walled (Su et al. 2016b).

Notes: Neotorula was introduced to accommodate a torula-like species N. aquatica collected from freshwater habitats in China (Su et al. 2016b). Neotorula shares similar characters with Torula Pers. in having clavate to subcylindrical, brown conidia forming in branched chains. However, the former has macronematous and septate conidiophores, while the latter has micronematous conidiophores reduced to conidiogenous cells or with one brown supporting cell (Su et al. 2016b). The placement of Neotorula was confirmed in Torulaceae based on sequence data of two freshwater species, N. aquatica and N. submersa Z.L. Luo et al. (Hyde et al. 2016b; Su et al. 2016b). Both species can be distinguished by the length of conidia (see key below).

Type species: Neotorula aquatica Z.L. Luo & K.D. Hyde.

Other accepted species: Species Fungorum – search Neotorula.
