manner, and rarely exceeding an inch and a halt' in breadth. The surface
is finely cottony, and pure white or greyish, marked by a few indistinct
zones. Beneath, the lamellæ are radiating, subparallel, hairy, coriaceous,
and of a reddish-brown or brown-grey colour. Lamellæ double ; that is,
composed of 2 rather remote plates, united at their back, and with their
sides involute, so that in a dry state they appear tubular when transversely
divided. They are arranged in distinct fasciculi : each double lamella
soon after its origin] divides into branches, each of which becomes again
subdivided in a fan-like mode ; but all these divisions are mithin the original
lamella ; that is, the outermost plate of the bundle of lamellæ, is
continuous, to the margin of the pileus, is larger, and rolled over the inclosed
divisions, and placed back to back with the adjoining boundary
plate of the next fasciculus. An examination of the figure will render the
mode of division more intelligible. Hymenium in the exterior surface of
the lamellæ. Sporules very minute, white.
A very curious fungus, found in every quarter of the globe ;
and, though extremely different from every known Agaric, was
retained in that genus until separated by F r i e s . One of its
greatest peculiarities is the singular mode of division of the lamella,
and which it is most difficult to describe. Another
equally striking one is their villosity. The tomentose surface
of the pileus is so thin, that it has occasionally been accidentally
removed ; and E u i . l i a r d informs us, that the plant has,
in that statCj been preserved as an extraordinary and precious
rarity.
