Retiboletus (Boletaceae) in northern Thailand: one novel species and two first records.Morphological characters and multi-gene phylogenetic analyses were used to identify Retiboletus specimens collected in northern Thailand.  Retiboletus brevibasidiatus is described as new to science, whereas R. fuscus and R. nigrogriseus are reported for the first time from Thailand.  Retiboletus brevibasidiatus produces medium-sized basidiomes, with a dark blonde to clay pileus and densely reticulate stipe mostly on the upper part with pale yellow to chrome yellow basal mycelium.
