Systema Mycologicum, Vol 2

These four varieties, each of which enjoys countless forms (Cf. Sterb. t. 10 Menzel. l. c. Bradley Farm. dir. p. 65. etc.), are not to be distinguished, for the color is not sufficiently constant *) and the form of the areolae evidently depends on the pileus.

2. M. deliciosa, with subcylindrical acute pileus attached at the base, firm longitudinal ribs, connected by transverse wrinkles, with a smooth stipe.

Boletus flavicans, with leafy head! Vaill. par. p. 21.
Fungus cavernosus cavernous fungus. Weinm. herb. t. 533. f. 1.
(also Menzel. var. 2 approaches this)

Tastier than the previous one, very related to var. δ, but not easily joined to it because of sufficiently acute characteristics. Stipe hollow, shorter than the pileus, hardly ever reaching an inch, about 3-4 lines a line is 1/12 of an inch thick, somewhat equal, but it varies, being thickened and compressed at the base; seen under a lens, it is covered with a thin villus fine hair, separating into small scales upon drying. Pileus conico-cylindrical, 1-2 ½ inches long, with almost parallel ribs, hardly anastomosing, but joined by transverse wrinkles. Areolae oblong-linear, deep. Color hitherto observed as yellowish, rarely livid-pale. In grassy, leafy places at the edges of fields, in spring. (v. v.)

3. M. elata, with conical somewhat obtuse pileus attached at the base, with membranaceous longitudinal ribs joined by transverse ones, with a scurfy stipe.

Stipe 2-3 inches long, an inch thick and more, very hollow and fragile, irregularly lacunose, paling, testaceous-whitish. Pileus ovate-conical,

*) The most accurate Bulliard, neglecting form, enumerates three varieties according to color: a.) white, then straw-colored. b.) ash-colored, g.) brown, then blackening. Cf. Dec. Fr. 2. p. 213. Of these, the latter is closest to our δ, the former to β, the other to α.
