Abstract:
Hydnangium echinulatum, described originally from a single specimen collected in Malaysia, has been recollected, and based on morphological and molecular characters is recognized as representing a new gasteroid genus of boletes with affinities to the Boletineae, herein named Durianella. Diagnostic features include an epigeous, ovoid, pyramidal-warted, durian fruit-like basidiome with gelatinized glebal locules and a columella that turns indigo blue upon exposure, and subglobose basidiospores with long, curved, thin-walled and collapsible spines. A redescription, phylogenetic analysis and comparison with allied taxa are presented.
