in botany, a genus of the cryptogamia fungi. Of this genus there are 28 species, 24 of which are are natives of Britain. Several species of the agaric grow upon the trunks of the larch, the oak, and other trees. It is of a spongy substance, resembling the mushroom, and irregular in its figure and size. This plant has of late been tried for stopping hemorrhages after amputations; but the success has not been so remarkable as to bring it into general use.
