“…The genus Thallomicrosporon was introduced with the type species Thallomicrosporon kuehnii, type strain CBS 119.64 (Benedek 1964). Benedek (1969) suggested that this species may have derived from another dermatophyte as a stable mutant. Molecular analyses in the current study showed that the type strain is identical to CBS 258.61, type of Nannizzia gypsea (99.7% LSU identity to NG064029 and 100% ITS identity to NR131271) and is therefore regarded as a synonym.…”

The order Onygenales is classified in the class Eurotiomycetes of the subphylum Pezizomycotina. Families in this order have classically been isolated from soil and dung, and two lineages contain causative agents of superficial, cutaneous, and systemic infections in mammals. The ecology and habitat choices of the species are driven mainly by abilities of keratin- and cellulose-degradation. The present study aimed to investigate whether the ecological trends of the members of the Onygenales can be interpreted in an evolutionary sense, linking phylogenetic parameters with habitat preferences, to achieve polyphasic definitions of the main taxonomic groups. Evolutionary processes were estimated by multiple gene genealogies and divergence time analysis. Previously described families namely, Arthrodermataceae, Ajellomycetaceae, Ascosphaeraceae, Eremascaceae, Gymnoascaceae, Onygenaceae and Spiromastigaceae were accepted in the Onygenales, and two new families, Auxarthraceae and Neogymnomycetaceae were introduced. A number of species could not be assigned to any of the defined families. Our study provides a revised overview of the main lines of taxonomy of the Onygenales, supported by multilocus analyses of ITS, LSU, TUB , TEF1 , TEF3 , RPB1 , RPB2, and ribosomal protein 60S L10 (L1) ( RP60S ) sequences, combined with available data on ecology, physiology, morphology, and genomics.

Nannizzia (N.) incurvata (formerly Microsporum incurvatum) represents a geophilic dermatophyte which has been previously classified as belonging to the species complex of N. gypsea (formerly Microsporum gypseum). A 42-year-old Vietnamese female from Saxony, Germany, suffered from tinea corporis of the right buttock after she returned from a 2-week-visit to her homeland Vietnam. From skin scrapings of lesions, N. incurvata grew on Sabouraud’s dextrose agar. Treatment by ciclopirox olamine cream twice daily for 4 weeks was successful. A 6-year-old Cambodian boy living near river Mekong with contact history to chicken, dogs and cattle suffered from tinea faciei and capitis. Symptoms of the favus-like tinea capitis and tinea faciei were erythema and scaly patches with areas of alopecia. N. incurvata grew on Sabouraud's dextrose agar. The boy was treated with oral terbinafine 125 mg daily, topical miconazole cream and ketoconazole shampoo. The symptoms healed within 4 weeks of treatment. Cultivation of the samples revealed growth of N. incurvata. For confirmation of species identification, the isolates were subject to sequencing of ITS (internal transcribed spacer) region of the rDNA, and addition of the “translation elongation factor 1 α” (TEF 1 α) gene. Sequencing of the ITS region showed 100% accordance with the sequence of N. incurvata deposited at the NCBI database under the accession number MF415405. N. incurvata is a rare, or might be underdiagnosed geophilic dermatophyte described in Sri Lanka and Vietnam until now. This is the first isolation of N. incurvata in Cambodia, and the first description of favus in a child due to this dermatophyte.

A number of species could not be assigned to any of the defined families.
