The term Ceriomyces speciosus (Frost) Murrill is synonymous with obsleto.

Etymology –
The term Boletus is of controversial etymology: according to some authors it derives from the Greek βωλήτης bolétes, with which the Greeks called a kind of mushroom (from βωλος bólos with the meaning of gleba, clod, bush, because growing among the clods or bushy places); others instead believe that the meaning of βωλος is to be extended to the ball, since the hat of most mushrooms is globose; for other still it derives from Bolites name with which the Romans indicated the best edible mushrooms, even if originally referred only to the ova (Amanita cesarea), but soon used to call also the porcini mushrooms. The specific epithet speciosus derives from spécies beltà: good-looking, showy, elegant.

Recognition –
Boleto specioso is recognized for having a hat 6-15 cm in diameter, convex, with a cuticle dry, smooth, light red or pink and sometimes with yellow hues.

The stem has dimensions of 5-13 x 1.5-4 cm; it is compact, yellow with reddish hues at the base, cross-linked and quickly turns blue to the touch. The meat is yellow in color, often yellow-chromium at the base of the stalk, turns quickly to blue and has not significant odor and taste. Under the microscope, spores of 11-15 x 3-4 μm, smooth, brown-olive in bulk can be noticed.
