Glomeromycota: three new genera and glomoid species reorganized

Abstract

Species in the orders Glomerales and Diversisporales ( Glomeromycetes ) with glomoid spore formation are reorganized based on combined ribosomal sequence and morphological analyses. Within the Glomerales two genera in the Glomeraceae ( Septoglomus, Simiglomus ) and one genus in the Claroideoglomeraceae ( Viscospora ) are proposed as new. Paraglomerales species (thus far monogeneric) also form glomoid spores that may all germinate directly through the spore wall instead through subtending hyphae as in Glomerales .
