Pygmaeomycetaceae, a new root-associated family in Mucoromycotina from the pygmy pine plains.

A new genus, , and two new species are described based on phylogenetic analyses and phenotypic and ecological characters. The species delimitation was based on concordance of gene genealogies. The cultures were isolated from the roots of mountain laurel () and pitch pine () from the acidic and oligotrophic New Jersey pygmy pine plains; however, they likely have a broader distribution because their internal transcribed spacer (ITS) sequences have high similarity to a number of environmental sequences from multiple independent studies.

Cadophora meredithiae and C. interclivum, new species from roots of sedge and spruce in a western Canada subalpine forest.

Two new species of Cadophora are described based on multigene phylogenetic analyses and phenotypic and ecological characters. The species delimitation was based on concordance of gene genealogies. The cultures of the Cadophora species were isolated from the roots of long-beaked sedge and white spruce from a subalpine forest in western Canada; however, they probably have a broader distribution because their internal transcribed spacer (ITS) sequences have high similarity with a number of GenBank sequences from ecological studies of plant roots.
