مستخلص: | Background: Fungi clinically relevant to human skin comprise prevalent commensals and well-known pathogens. Only rarely human skin harbours fungi that evade identification. Objective: To characterise an enigmatic specimen isolated from a skin lesion. Methods: A comprehensive clinical and mycological workup including conventional methods for phenotypic characterisation and sequencing based on internal transcribed spacer (ITS) and large subunit (LSU) regions to infer a phylogenetic tree. Results: Cultures on common solid media were macroscopically inconspicuous initially until mycelial tufts developed on the surface, notably on potato dextrose agar. Polymorphous chlamydospores were detected but no aleurospores and ascomata. At 26°C, the isolate grew on standard agars, plant materials and garden soil and utilised peptone, keratins, lipids, inulin, erythrocytes and cellulose. It also grew at 5°C and at 37°C. Nucleotide sequences of its ITS region showed 93% similarity to sequences of different Malbranchea species. The closest matches among LSU rRNA sequences were obtained with the genera Amauroascus, Arthroderma, Auxarthronopsis and Malbranchea (93%-95%). A combined phylogenetic analysis placed the fungus in a sister clade to Neogymnomycetaceae, classified as incertae sedis in Onygenales, on a large distance to either Diploospora rosea or 'Amauroascus' aureus. Conclusions: The genus Inopinatus gen. nov. (MB854685) with the species Inopinatus corneliae sp. nov. (MB854687) is introduced to accommodate our isolate (holotype: DSM 116806; isotypes: CBS 151104, IHEM 29063). Probably Inopinatus corneliae is a geophilic species that, although potentially harmful, was no relevant pathogen in our case. Its ecology, epidemiology and pathogenicity need to be further clarified. (© 2024 The Author(s). Mycoses published by Wiley‐VCH GmbH.) |
