Index Fungorum, Facesoffungi, MycoBank, GenBank

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

Anamorph: Conidiophores solitary, erect, subcylindrical, straight, slightly flexuous, unbranched, medium brown, smooth, septate, terminating in a phialide, or in a penicillate head: primary branches subcylindrical to doliform, medium brown, smooth; secondary branches doliform to subcylindrical, medium brown, smooth, giving rise to phialides. Conidiogenous cells phialidic, ampulliform, medium brown, smooth, including the apical collarette, cylindrical, medium brown. Conidia occurring in chains, unbranched, hyaline, smooth-walled, cylindrical, aseptate, ends truncate (Adapted from Crous et al. 2018a, b). Teleomorph: Unknown.

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

Geographical distribution: Australia, China, Colombia, France and Thailand. 

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

Accepted chalara-like genera: Exochalara, Lareunionomyces, Neolauriomyces and Minichalara.

Notes: The family Neolauriomycetaceae was created to accommodate three hyphomycetes genera, namely Exochalara, Lareunionomyces and Neolauriomyces (Crous et al. 2018a, b). None of these fungi was known with teleomorph (Crous et al. 2016a, b, 2018a, b, 2019). Based on this study (Figs. 3, 127; Wenping Wu et al. 2023), the family was further expanded with a new genus Minichalara and 5 additional species, including one new combination and four new species. In the phylogenetic trees (Figs. 3, 127; Wenping Wu et al. 2023) generated from two different datasets of integrated LSU and ITS sequences, separation of Exochalara, Lareunionomyces and Neolauriomyces was strongly supported, and species of each genus formed a distinct lineage with strong support in at least one of the dataset. Two species of Minichalara, M. aseptata and M. microspora did not cluster into one strongly supported group. However, these two species were morphologically very similar, and treated as one genus for now. Roseodiscus sinicus also clustered together with other members of Neolauriomycetaceae. Roseodiscus sinicus was clearly genetically distinct from the type species of Roseodiscus, R. rhodoleucus (Johnston et al. 2014a, b). Future study with involvement of more species and marker genes might support a better resolution of the family.

Type genus: Neolauriomyces Crous.

Other accepted species: Species Fungorum – search Neolauriomycetaceae.
