Endogone corticioides sp. nov. was described from subalpine conifer forests in Japan and China. This species is similar to E. pisiformis in its yellowish sporocarps and zygosporangia on the equal empty gametangia. Endogone corticioides was clearly distinguished from E. pisiformis based on its resupinate sporocarp, the presence of hyphal peg-like structures on the peridium, and abundant thick-walled hyphae in the gleba. Phylogenetic analysis of the small and large subunit nuclear ribosomal RNA and the elongation factor-1α genes suggested that E. corticioides is closely related to E. pisiformis. Limited vegetative growth from the surface-sterilized sporocarps on agar media was shown.
