Keratinomyces ceretanicus was described as a new taxon distinct from Trichophyton ajelloi. Because of the morphological similarity between the two species, their mating behaviour was studied. The optimum temperature for growth of K. ceretanicus was found to be 25 degrees C rather than 17 degrees C. The type culture produced moderate numbers of microconidia on potato glucose agar after 2 weeks at 25 degrees C and a large number of smooth, thick-walled, cylindro-fusiform, 7-to 12-celled macroconidia. On Sabouraud glucose agar containing chloramphenicol and cycloheximide growth was partially but not completely inhibited. When crossed on a soil-hair medium, K. ceretanicus produced fertile gymnothecia typical of Arthroderma uncinatum with 10 (-) mating type isolates of A. uncinatum. As a result, it is concluded that K. ceretanicus is a facultative synonym of T. ajelloi.
塞雷坦角状毛癣菌被描述为一个不同于阿杰洛毛癣菌的新分类单元。由于这两个物种在形态上相似，因此对它们的交配行为进行了研究。发现塞雷坦角状毛癣菌生长的最适温度为25℃，而非17℃。该模式培养物在25℃下于马铃薯葡萄糖琼脂上培养2周后产生适量的小分生孢子，以及大量光滑、厚壁、圆柱形至梭形、7至12个细胞的大分生孢子。在含有氯霉素和放线菌酮的沙氏葡萄糖琼脂上生长受到部分但未完全抑制。当在土壤毛发培养基上进行杂交时，塞雷坦角状毛癣菌与10株阿杰洛毛癣菌的（-）交配型分离株产生了典型的阿杰洛毛癣菌可育裸囊壳。因此，得出结论：塞雷坦角状毛癣菌是阿杰洛毛癣菌的兼性同物异名。
