A species formerly incorrectly confused with M. esculenta, with which it is analogous in this section; but now M. esculenta γ is often sold under this name! Stipe very hollow, long (about 2 inches), whitish, furfuraceous-squamulose covered with bran-like scales and not striated. Pileus from a roundish-ovate shape becomes obtusely conical, free to the middle, tapering toward the margin, yellow above, reddish, tawny-brown, darker when dry. Areolae smooth inside. On the ground in mountainous places, in spring. At Stockholm. Sw. (seen in specimen)

8. M. semilibera, with conical pileus free to the middle, longitudinal ribs joined by oblong areolae which are veined inside, and a smooth stipe.
