Periconia Tode, Fung. mecklenb. sel. ( Lueneburg) 2: 2 (1791)

Notes.

Periconia was established by Tode (1791) to accommodate dematiaceous hyphomycetes that were unique in forming macronematous, mononematous, branched, septate, pigmented conidiophores, bearing spherical conidial heads that produced globose to ellipsoidal, aseptate, verruculose to echinulate, pigmented conidia ( Tanaka et al. 2015; Hongsanan et al. 2020; Yang et al. 2022b). Species of Periconia are typically known by their asexual morph; only a few species have been reported with their sexual morph ( Tanaka et al. 2015; Hongsanan et al. 2020; Yang et al. 2022b). Periconia species have been commonly reported as saprobes occurring on various host substrates in terrestrial and aquatic habitats worldwide. However, some species have been reported as endophytes, plant pathogens (e.g. P. circinata , P. digitata and P. macrospinosa ) and human pathogens, as well as producing economically-important bioactive compounds ( Sarkar et al. 2019; Gunasekaran et al. 2021; Hongsanan et al. 2020; Samarakoon et al. 2021; Azhari and Supratman 2021; Yang et al. 2022b; Su et al. 2023). Even though over 200 species of Periconia were listed in Index Fungorum (http://www.indexfungorum.org; accessed on 25 May 2023), less than half of a quarter have molecular data to clarify phylogenetic placement. Of these, the type species of Periconia , P. lichenoides , also lacks molecular data. This suggests that there is a huge research gap in the taxonomic classification of the genus Periconia . In the present study, we follow the latest taxonomic treatment of Yang et al. (2022b) and Su et al. (2023) and the new species Periconia kunmingensis occurring on fern, is introduced.
