A new genus, Complexispora, with two new species, C. multistratosa and C. mediterranea, and Epigeocarpum japonicum sp. nov.

Abstract

Abstract Morphological analyses of three glomoid spore-producing fungi suggested that two of them are undescribed species of Glomeraceae or glomoid spore-producing members of Entrophospora in Entrophosporaceae (phylum Glomeromycota), and the third differed slightly from Dominikia glomerocarpica and Epigeocarpum crypticum, recently described in Glomeraceae. The first two fungi originated from the Mediterranean Sea sand dunes of the Peloponnese, Greece, and the third was originally found in a tree plantation in Yokohama City, Japan. Phylogenetic analyses of sequences of the 45S nuc rDNA region and the RPB1 gene showed that the three fungi are undescribed species in Glomeraceae. The first two species represented a new genus, here described as Complexispora with C. multistratosa sp. nov. and C. mediterranea sp. nov. The third species enlarged the monospecific genus Epigeocarpum, as E. japonicum.
