A new genus of Boletaceae from eastern North America.
Bothia is described as a new genus in the Boletaceae based on Boletinus castanellus described by C.H. Peck from eastern North America. A widespread, occasionally encountered taxon, Bothia castanella possesses a combination of macro- and microscopic features that has prompted past placement in seven different genera. Yet, as a species it is readily recognizable with its chestnut brown, dry pileus, decurrent, pale brown hymenophore with radially elongated tubes, a short, sometimes eccentric, exannulate stipe, yellow brown spore deposit and constant association with Quercus. Phylogenetic analyses of large subunit rDNA and BLAST searches using the ITS region confirm the placement of B. castanella as a unique generic lineage in the Boletaceae.
