The order Onygenales is classified in the class Eurotiomycetes of the subphylum *** in this order have classically been isolated from soil and dung,and two lineages contain causative agents of superficial,cutaneous and systemic infections in *** ecology and habitat choices of the species are driven mainly by the keratin and cellulose degradation *** present study aimed to investigate whether the ecological trends of the members of Onygenales can be interpreted in an evolutionary sense,linking phylogenetic parameters with habitat preferences,to achieve polyphasic definitions of the main taxonomic *** processes were estimated by multiple gene genealogies and divergence time *** described families,namely,Arthrodermataceae,Ajellomycetaceae,Ascosphaeraceae,Eremascaceae,Gymnoascaceae,Onygenaceae and Spiromastigoidaceae,were accepted in Onygenales,and two new families,Malbrancheaceae and Neogymnomycetaceae,were introduced.A number of species could not be assigned to any of the defined *** study provides a revised overview of the main lines of taxonomy of 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.

Background: Onychomycosis results from invasion of the nail plate by dermatophytes, yeasts or mould species of fungi. This report documents the etiological agents of onychomycosis in Adana, Turkey. Methods: Results of mycological tests of nail clippings or subungal scrapings collected in the period between 1998 and 2002 were analyzed. Both the direct microscopy and the cultures of the nail mater ial were performed to identify the causative agent. Results: Out of a total of 3 88 cases examined, finger (12.4%) and toenail (87.6%) involvement, 155 (39.9% ), were mycologically proven cases of onychomycosis (15 finger, 140 toenail). Am ong the 98 specimens from positive fungal cultures, dermatophytes were isolated in 74 (75.5%), and yeasts in 24 (24.5%). Trichophyton rubrum was the most comm on causative agent (48.0%), followed by T. mentago phytes var. interdigitale (2 6.6%), Candida tropicalis (11.2%), C. albicans (9.2%), C. glabrata (2.0%), C . krusei (2.0%) and Epidermophyton floccosum (1.0%). Conclusions: Dermatophyte fungi, especially T. rubrum, and T. mentagrophytes var. interdigitale, were res ponsible for most of the infections.
