Osservazioni sulle raccolte fotografate La raccolta è stata determinata dopo analisi macroscopica. La specie è stata inserita recentemente nel nuovo genere Butyriboletus Arora & J.L. Frank: The butter boletes (Boletus s.l. sect. Appendiculati) are an economically important group of ectomycorrhizal fungi whose basidiocarps have a yellow tube layer that often bruises blue, yellow reticulate stipe, mild flavor and firm yellow-tinged flesh that may or may not turn blue when exposed. Morphological characters and molecular data (ITS and LSU) place this group in a separate phylogenetic clade from Boletus sensu stricto. Here we establish a new genus, Butyriboletus, to accommodate 14 species of butter boletes that range from Asia to Europe, north Africa and North America. Da Mycologia, 106(3), 2014, pp. 464–480.
