<i>Inocybe alboaurantiaca</i> (Inocybaceae), a new species from Asia

A new Inocybe (Inocybaceae) species, Inocybe alboaurantiaca , is described and illustrated from Asia (Japan and Pakistan), based on morphological and phylogenetic analyses of the nrITS and nrLSU regions. Phylogenetically, the most closely related sequences belong to the current mainstream European concept of Inocybe fibrosa. Inocybe alboaurantiaca is characterized by its white to yellowish‐orange basidiomata, conic‐subcampanulate and uncracking pileus, nodulose basidiospores (8.90 × 6.06 μm) having blunt knobs, and short‐plumpish fusiform hymenial cystidia. Morphological descriptions, colored photographs, microscopic structures, and a comparative nrITS‐ and nrLSU‐based phylogenetic analyses are presented with reference to the newly described species.
