Index Fungorum, Facesoffungi, MycoBank, GenBank

Classification: Neolauriomycetaceae, Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi

Mycelium consisting of hyaline, smooth, branched hyphae. Anamorph: Conidiophores solitary, erect, subcylindrical, straight, slightly flexuous, unbranched, dark brown, smooth, septate, thick-walled, basal cell slightly swollen, lacking rhizoid, terminating in a pale brown penicillate conidiogenous apparatus. Penicillate conidiogenous apparatus pale brown, smooth; primary branches subcylindrical to doliform, medium brown, smooth; secondary branches doliform to subcylindrical, medium brown, smooth, giving rise to 1–2 phialides. Conidiogenous cells phialidic, ampulliform, medium brown, smooth, with apical cylindrical collarette. Conidia endogenous, extruded in short and dry chains, hyaline, smooth, subcylindrical, aseptate, ends truncate (Adapted from Crous et al. 2018b). Teleomorph: Unknown.

Ecology/substrate/host: Saprobe on dead leaves of trees.

Geographical distribution: Australia and China.

Description and illustration: Crous et al. (2018b).

Notes: The genus Neolauriomyces was created for N. eucalypti, which morphologically resembled Lareunionomyces in conidiogenous apparatus and conidial morphology, but differed phylogenetically (Wingfield et al. 1987; Crous and Wingfield 1994; Jacobs et al. 2003; Crous et al. 2018b). In Lareunionomyces conidiogenous apparatus are more intricate, with numerous tightly aggregated branches and phialides, and conidia are formed in slimy droplet or cylindrical slimy mass; while in Neolauriomyces, conidiogenous apparatus are much simple with 1 primary branch and 1–2 secondary branches, each bearing 1–3 ampulliform-shaped conidiogenous cells, and conidia are formed in short and dry chains (Crous et al. 2016b, 2018b). Three species, including two new species, are accepted under the genus (Fig. 127; Wenping Wu et al. 2023).

Type species: Neolauriomyces eucalypti Crous.

Other accepted species: Species Fungorum – search Neolauriomyces.
