Hydropodia silvae-nipponicae ( Porotheleaceae), a new species from evergreen broad-leaved forests in Japan

Abstract

Hydropodia silvae-nipponicae, a new agaric species was described based on the specimens collected from evergreen broad-leaved forests in Japan. The present new species is distinct from H. subalpina, the type species of the genus by morphological characteristics and nuclear rDNA sequences. Hydropodia silvae-nipponicae is characterized by its nodulose cystidium-like terminal elements of pileipellis, cylindrical to clavate pileocystidia with irregular excrescences, and dimorphic pleurocystidia. It is the second species belonging to the genus Hydropodia.
