Phylloporus gajari, a new species of the family Boletaceae from Bangladesh

• Phylloporus gajari is the first described species of Phylloporus from Bangladesh.
• Phylloporus bellus differs from P. gajari by its pallid yellow stipe and size of spores.
• This species is putatively an ectomycorrhizal fungus, associated with Shorea robusta.

Phylloporus gajari, a new species, based on morphological and molecular data, is described and illustrated from tropical Asian forests dominated by Shorea robusta. It is morphologically circumscribed by its reddish brown to yellowish brown, sub-tomentose and rimose pileus when mature, sub-crowded cyanescent lamellae, red to reddish brown stipe, bacillate basidiospores, and habitat in forests dominated by Shorea robusta. Molecular phylogenetic analysis using the nuclear ribosomal large subunit RNA also supports the new species in Boletaceae. We compare it with phenotypically similar and molecular phylogenetically allied taxa.
