(The name of a fungus considered a great delicacy among the Romans, derived from )8<, a clod, probably to denote the round figure of the plant.) Hymenium wholly composed of small tubes, connected together in a stratum the surface of which is dotted with their poriform mouths, and which is distinct from the hymenophore on account of the latter not descending into a trama. Tubes packed close together, easily separating from the hymenophore and from one another. Pores or mouths of the tubes round or angu- lar (in the subgenus Gyrodon sinuous or gyroso-plicate). Spores normally fusiform, rarely oval or somewhat round. Growing 071 tJie ground, fie shy, putrescent, with central stems. Mostly edible, and of importance as articles of food; a few poisonous. A well-marked and sharply de- fined genus, although some of the species depart so much from the type that they have been referred to distinct genera. Fr. Hym. 495. Compare Epicr. p. 408 and Syst. Myc. i. p. 385. The colour of the spores of many of the species is unknown,. LX. Boletus edulis.
