BOLETUS ungulatus. Schæff. 136, 137? Bull. 401, & 491.
On willows most frequent. It is sessile, varying in shape, but often resembling an horse's hoof. The pileus, when young, is fox-coloured, and somewhat tomentose, but becomes very hard, though fibrous by age, so as to endure all seasons, and even defy the ravages of infects for more than 7 or 8 years, growing or dried. The tubes are long, and mostly cylindrical, very fine, growing under each other in layers periodically; in the beginning of each period, commonly giving a whitish farina, afterwards a ferruginous powder. This is the Agaricus chirurgorum, Edin. Pharm. formerly having been recommended as a styptic. It is manufactured for tinder, &c. on the Continent in many places, by beating, boiling in lye and saltpetre, &c. In Franconia, they are said to beat the inner substance into the form of leather, and few it together for garments.

BOLETUS fomentarius. Linn. Sp. 1645. F. S. 1252. With. 3, ed. 333.
Seems commonly confounded with the preceding,and often resembles it in every varied shape, but grows quicker, seldom enduring more than season, perhaps from August to December. The fibres are softer, and easily pervaded by insects. &c. It is made into tinder without beating, and used in Germany, particularly about the Hartze, so famous for its rich mines. I have the authority of the ingenious Dr. Afzelius, formerly a pupil of Linnæus, for authenticating this species. The tubes are mostly equal and exude copiously a glaucous farina in the growing state, which may be scraped off. In the latter state, they exude a ferruginous powder. Are not B. pseudo-ignarius Bull. 458, and B. ungulatus Schæff. 138, this species?
