The anamorphic genus Calcarisporiella is a new member of the Mucoromycotina

The phylogenetic position of the anamorphic genus Calcarisporiella was investigated. Three isolates of Calcarisporiella, including an authentic strain and a newly obtained isolate, were analyzed phylogenetically using rDNA sequences. The result indicated that Calcarisporiella, which was classified as an ascomycetous anamorph, is a member of Mucoromycotina. It formed an independent clade separated from the other known orders of this subphylum.
