Strobilomyces verruculosus sp. nov. from Japan

A new species, Strobilomyces verruculosus, is described and illustrated. It is morphologically distinct from other species of Strobilomyces by having a verruculose pileus with small subpyramidal scales, a long and thick stipe with small warty to appressed scales, subdecurrent tubes, and incompletely reticulate basidiospores. Molecular phylogenetic analyses using the mitochondrial cytochrome oxidase subunit 3 (cox3) gene support that it belongs to the genus Strobilomyces and is highly differentiated from the other members of this genus found in Japan.
