fprinkled with the little ftarry whitifh orifices of the heads, 

 full of orange powder. Lycoperdon epiphyllum of Hudfon 

 and Lightfoot are different from this, and perhaps from each 

 other. Uredo tujftlaginis refembles our plant in general 

 afpeft, but on near examination will be found lefs diftinft, 

 in the form of an orange powder, intermixed with the cot- 

 ton of the Colt's-foot leaf, without diftinft white ftarry 

 heads. 



Ae. lerberidis. Barberrj- jEcidium. Perf. n. ii. Sowerb. 

 Fung. t. 397. f. 5. (Lycoperdon pocuhforme ; Jacq. Coll. 

 V. I. 122. t. 4. f. I.) — Bafe orbicular, fcarcely convex. 

 Heads cylindrical, fomewhat elongated, yellow. — Found on 

 leaves of the Barberry, in cold wet autumnal weather, fome- 

 times in the fpring, confifting of very confpicuous and pro- 

 minent tawny fpots, the heads projefting much. The orifice 

 of each is neither dilated, nor confpicuoudy toothed or 

 jagged. The whole turns brown, or black, in decay, and 

 may be obferved in that ftate on the fallen leaves during 

 winter. 



Seft. 2. Simple. Heads fc ottered, not combined by any 

 diflinEf critjl, or bafe. Six fpecies. 



Ae. euphorbia. Spurge Aecidium. Perf. n. ij. " Humb. 

 Friberg. 128." (" Lycoperdon euphorbiae ; Schrank. Ba- 

 var. v. 2. 631." Efula degener ; Rivin. Tetrap. Irr. t. 113. 

 f. 2.) — Simple, crowded. Heads pale, cylindrical, reflexed 

 at the margin. Powder orange-coloured. — Frequent in 

 fummer on the leaves of Euphorbia Cyparijftas, in Germany, 

 France, and Switzerland, caufing the whole plant to aflume 

 a difeafed appearance, and often to fail of producing flowers. 

 We fcarcely think Rivinus, as Perfoon hints, meant to con- 

 fider this difeafed Euphorbia as a diftinft fpecies. 



Ae. tragopogi. Goat's-beard ^cidium. Perf. n. ty, b. 

 Sowerb. Fung. t. 397. f. 2. — Scattered. Heads fomewhat 

 elliptical, with an irregularly torn white margin. Powder 

 yellow. — On the ftem and leaves of Tragopogon pratenjis. 

 Confpicuous for its (hort white heads. Perfoon. Tiiat 

 author certainly means to defcribe this as a diftinft fpecies 

 from the laft, though by an error, which ought to have been 

 corrected in printing, he has given the fame number to both. 

 Hence he has really twenty fpecies in all, though apparently 

 but nineteen. 



Ae. anemones. Wood-Anemone .fficidium. Perf. n. 17. 

 Uft. Annal. v. 20. 135. (Lycoperdon anemones; Pulten. 

 Tr. of Linn. Soc. v. 2. 311.) — Simple, fcattered. Heads 

 cylindrical, rather prominent, pale, moftly toothed, filled 

 entirely with white powder. — Found in the fpring on leaves 

 of Anemone nemorofa, rendering the plant fickly, and often 

 barren. Dr. Pulteney obferved that this fungus originates 

 under the cuticle, and may be feen, in a young ftate, through 

 that membrane. At length each individual aflumes a nearly 

 globular form, burfting with lacerated edges, the cavity 

 being lined Avith white po-v/dery feeds, intermixed with mi- 

 nute fibres. In fading, each turns yellowifh, then brown, 

 and finally " each fungus is refolved into a farinofe particle, 

 refembling the fruftification of a Polypody." Pulteney. 

 The JE. fufcum, Relh. Cant. 546. Sowerb. Fung. t. 53, 

 found on the leaves and petals of the fame fpecies of Ane- 

 mone, without injuring the plant, is the Puccinia anemones, 

 Perf. Syn. Fung. 226, a genus defcribed as deftitute of a 

 head, or peridium. In this refpeft we find it difficult to 

 draw a line between Mr. Sowerby's figure, and his various 

 reprefentations'of jEcidia, t. 39S, though we doubt not the 

 fpecific difference of the above two plants. Which of them 

 is the " Conjurer of Chalgrave's Fern," Dill, in Raii Syn. 

 124. t. 3. f. I, may be doubted ; but we rather fuppofe the 

 Puccinia.

Ae.punaalum. Yellow-Anemone jEcidium. Perf n 18 

 Uft. Annal. v. 20. 135. (Ae. anemones; Hoffm. Germ. 

 v. 2. t. 1 1, f. i.)_« Simple, fcattered. Heads partly funk, 

 their border nearly clofed. Powder compaft, brownifh."— 

 Found rarely on the leaves of Anemone ranunculoides, which 

 It marks with brown dots. The border of the onfice is but 

 (lightly, if at all, toothed. Seeds chefnut-coloured. Perfoon. 

 We have not heard of this fpecies in Britain. 



Mr. Sowerby has reprefented feveral more fpecies of this 

 genus m his Englijl, Fungi, t. 397, 398, fuch as £. corni, 

 confuens, rubi, fragaria, nenlhx, falicis, cardui, rhei ; but 

 we do not fee clearly how the generic difference between 

 yEcidium and Puccinia is, in moft of them, to be determined.
