On willows moft ficfiiient. It is felTile, varying in 

 lliape, but often refcmhling an hoiil's hoof. 'J he pi- 

 leus, when }-oung, is fox-coloined, and Ibmewhat to- 

 mentofe, but becomes very hard,tliOiigh fibrous by age, 

 lb as to endure all feafons, and even defy the ravages of 

 infects for more than 7 or 8 )'ears, growing or dried. 

 The tubes are long, and moftly cylindrical, very fine, 

 growing under each other in layers periodically ; in 

 the beginning of each period, commonly giving a 

 whitilh farina, afterwards a ferruginous powder. 1 his 

 is the Agaricus chirurgorum, Edin. Pharm. formerly 

 having been recommended as a liyptic. It is manu- 

 factured for tinder, 8cc. on the Continent in many 

 places, by beating, boiling in lye and faltpetre, &:c. In 

 Franconia, they are faid to beat the inner fubllance 

 into the form of leather, and few it together for gar- 

 ments.

Seems commonly confounded with the preceding,and 

 often refembles it in eveiy varied fliapc, but grows 

 quicker, feldom enduring more than afcafon, perhaps 

 from Au^ult to Decem])cr. The fibres are fbfter, and ea- 

 fily pervaded by infedfs. See It is made mto tinder with- 

 out beating, and ufcd in Cicrmany, particularly about 

 the Ilart'/e, fo famous for its rich mines. I have the 

 authorit}' of the ingenious Dr. Af/.clius, formerly a pu- 

 pil of Linnxus, for authenticating this foecies. The 

 tubes are moftly e(]uaL and exude copioufiN' a glaucous 

 farina in the gro\Ning ftate, which ma\' be fcraped olY. 

 In tlic latter Itate, tliey exude a ferruginous powder.
