Crossing of Trichophyton rubrum with Arthroderma simii yielded many ascomata around the fluffy T. rubrum colonies. One of the 35 supposed ascospores isolated from matured ascoma was shown to be a hybrid of the two species. Hybrids were observed within the genotypes of four different genes, i.e., rRNA, actin, DNA topoisomerase II and cytochrome b. These results strongly suggest that T. rubrum is not an asexual or clonal species.
红色毛癣菌与须毛癣菌杂交后，在毛茸茸的红色毛癣菌菌落周围产生了许多子囊壳。从成熟的子囊壳中分离出的 35 个假定子囊孢子之一被证明是两个物种的杂种。杂种出现在 4 个不同基因的基因型中，即 rRNA、肌动蛋白、DNA 拓扑异构酶 II 和细胞色素 b。这些结果强烈表明红色毛癣菌不是无性或克隆种。
