Mating behaviour ofKeratinomyces ceretanicuswithArthroderma uncinatum

Re-evaluation of the synonymy betweenKeratinomyces ceretanicusandTrichophyton ajelloi

“…Results of our mating experiments (Table 1) concurred with Padhye et al [5] that CDC B-4562 (as ATCC 58594) produced fertile ascomata when mated with (-) mating type strains of A. uncinatum (UAMH 2930 and 3272). Although purportedly derived from the type specimen, CDC B-4562 behaved differently from UAMH 5384, which failed to mate with any tester strain of A. uncinatum.…”

“…Padhye et al [5] placed K. ceretanicus in synonymy with Trichophyton ajelloi based on the production of fertile ascomata when ATCC 58594, a strain purportedly derived from the type of K. ceretanicus, was mated with (-) mating type strains of Arthroderma uncinatum. Padhye et al reported that ATCC 58594 produced smooth, thick-walled cylindro-fusiform 7-12-celled macroconidia, moderate numbers of microconidia, and grew optimally at 25°C rather than 17°C.…”
