H ab. On th e ground, in Spring. Foxhall, near Edinburgh, Captain

Plant solitary, 2-5 inches in diameter, of a reddish-brown within, whitish
or brownish-white, on the outer surface, and somewhat farinose. In the
young state, the cup or pileus is roundish, depressed, the margin very
connivent, and the base within umbilicate and pUcate. During the period
of growth, the g eneral form becomes more depressed, and a number
o f lacerations are produced, of w hich one or more often reach nearly to
th e centre. In the last stage, the pileus is nearly spread out on every
side, so as to rest on the ground, the extreme margin, however, still retaining
its involute tendency : the centre is now much reticulated with
anastomosing ribs, undulate and unequal, especially when there is a
stipes, from the sides being p a rtly deplexed. Stipes either present or
nearly wanting : when present, h a lf an inch high or more, and nearly
as thick, somewhat lacunose. Substance carnose, fragile, one-tenth to
one-eighth of an inch thick. Sporules 8, oval.
