Phylogenetic placement of Diplocystis wrightii in the Sclerodermatineae (Boletales) based on nuclear ribosomal large subunit DNA sequences

Diplocystis wrightii is an enigmatic gasteroid basidiomycete from the Caribbean. It has taxonomic affi liations with Lycoperdaceae, Broomeiaceae, and Sclerodermataceae. This study sampled ITS and 28S ribosomal genes from three D. wrightii specimens to determine the phylogenetic placement and the closest relatives of this species. Results of database searches and phylogenetic analysis indicate this species to be a member of the Sclerodermatineae and most closely related to the genera Astraeus and Tremellogaster.
