Stirps Ferrugineus

Singer (1976: 217) grouped M. ferrugineus and its variety (elevated herein to species), and M. anomalus , M. bambusinus Fr. , M. guzmanianus Singer , M. hypophaeus , M. montagneanus Singer , M. nogalesii Singer , M. phaeocystis Singer , and M. tenuisetulosus (Singer) Singer in this stirps. The clade Ferrugineus (Fig. 1) seems consistent with stirps Ferrugineus as it includes M. ferrugineus sensu Antonín et al. (2012) from South Korea with additional strains from China and M. gardneri from Brazil. Data including M. ferrugineus topotypic collections along with other species are needed to further elucidate this group. Based on morphology, M. bambusinus described below seems to belong to this group but sequencing failed in this study. On the other hand, M. anomalus grouped with M. hinnuleus sensu Grace et al. (2019) , M. grandisetulosus (very similar to M. tenuisetulosus ) and M. hypophaeus sensu Wannathes et al. (2009) forming a monophyletic group distant from clade Ferrugineus. The authentic M. hypophaeus should branch in clade Ferrigineus though.
