(Bol. annulatus. Seineff. Ag. chirurgorum. Ed. Pharm. E.) On various 
kinds of trees. I have chiefly seen it on the cherry and plum. (On 
willows frequent. Sowerby. 
Poisonous. Purt. probably more so mechanically than chemically, as is the 
case with many such indigestible substances. E.) 
:V? Bol. fomenta'rius. (Linn.) Tubes sea-green: pores circular, 
equal: pileus white, convex, thick at the edge, uneven.

Bol. acaulis pulvinatus inoequalis obtusus , poris teretibus cequalibus glaucis. 
Exactly resembling a horse’s hoof, white above, hardly villose. Pores nu¬ 
merous, roundish. Linn. (Copiously emitting a glaucous powder when 
in a growing state; afterwards a ferrugineous powder. Grows quicker, 
• and is less permanent than the preceding species. E.)

It is used in Germany and some parts of England for tinder (also in most other 
parts of Europe and Asia.—Clarke’s Travels. E.) The Germans boil it in strong lye, 
dry it, and boil it again in a solution of saltpetre. The Laplanders burn it about their 
habitations in order to keep off a species of gadfly which is fatal to the young rein¬ 
deer. It is used to stop the bleeding from arteries after amputations. Phil. Trans, vol. 
48. p. 588. For this purpose the hard outer part is cut off, and the soft inner substance 
beat with a hammer to make it still softer. It is best when gathered in August or Sep¬ 
tember : (but its efficacy is not comparable to that of the ligature. In Franconia, ac¬ 
cording to Gleditsch, slices of the inner part beat to the consistence of leather, are sewed 
together to form garments. E.) 
$ (This species also serves for tinder, with less preparation than the former, and is 
used as such in the Hartze mountains. Indeed Baron de Beauvois asserts that this, 
rather than the preceding, is the real amadou of commerce so essential to German 
smokers, and sometimes rolled in gunpowder to render it more combustible, when thus 
impregnated called black amadou; otherwise red. It is produced in pieces about the 
size of cabbage leaves, and usually sold for one shilling or eighteen pence an ounce. 
The Highland shepherds prepare it for themselves. E.)
