Molecular evidence for a new putatively ectomycorrhizal bolete,"Boletus coccolobicola", from Belize.

An undescribed bolete, "Boletus coccolobicola", has been collected several times in the Chiquibul Forest of Belize. Although the collected material resembles a recently described taxon, Boletus neotropicus B. Ortiz and T. J. Baroni, it differs by having yellow (not white) mycelium at the stipe base, by its association with Coccoloba sp rather than Quercus, and by its shorter and slightly wider spores. ITS sequences, a phylogenetic analysis, and morphological data all highlight the difference between B. neotropicus and the new species. Ectomycorrhizae found below the stipe base of one collection of this bolete made in a small stand of Coccoloba sp were cloaked in yellow mycelia identical to that on the stipe base of the basidiome, providing evidence that this taxon is an ectomycorrhizal associate of Coccoloba sp.
