Gomphocantharellus, a new genus of Gomphales

ABSTRACT

The genus Gomphocantharellus and species Gomphocantharellus cylindrosporus are proposed as new based on morphological assessments and molecular phylogenetic evidence inferred from nucleotide sequences of mitochondrial (mt) adenosine triphosphate (ATPase) subunit 6 (atp6) and mt small subunit rDNA (mtSSU). Basidiomes of G. cylindrosporus are characterized by the peach to pinkish orange color, cantharelloid habit with a gill-like hymenophore with obtuse edges, smooth and cylindrical to allantoid basidiospores, and cylindrical to narrowly clavate flexuous pleurocystidia. The species resembles a species of Cantharellus but differs from the latter by the cylindrical basidiospores. Phylogenetic analyses confirm the placement of Gomphocantharellus as an independent lineage within the order Gomphales.
