Halonatospora gen. nov with H. pansihalos comb. nov and Glomus bareae sp nov (Glomeromycota; Glomeraceae)

We established single-species pot cultures of the former Glomus pansihalos, a member of the Glomeraceae, and obtained sequences of the SSU-ITS-LSU nrDNA segment and the RPB1 gene of the species. Phylogenetic analyses of the sequences indicated that G. pansihalos represents a separate Glade at the rank of genus in the Glomeraceae. Consequently, the new genus was named Halonatospora, and G. pansihalos was renamed Halonatospora pansihalos comb. nov. We also grew an AMF that produced clusters with glomoid spores in single-species cultures and obtained SSU-ITS-LSU and RPB1 sequences of the fungus. Studies of pot cultures, morphological and histochemical characters of the spores, as well as phylogenetic analyses of the sequences proved that it is an undescribed species of the genus Glomus sensu stricto, which is associated with roots of Ammophila arenaria colonizing maritime sand dunes located in north-western Poland.
