170 FUNGI. [Thelephora. 



variegated with bands of different shades running pru*allel with the 

 surface. When broken it gives out a milky juice which in taste and 

 smell resembles exactly that of Agancus quietus. Specimens which 

 had been placed in a tin box, when taken out after some months had a 

 broad byssoid margin, very different from their original state. A most 

 singular and distinct species, and undoubtedly a true Thelephora. 



27. T. gigdntea, Pers. (large ivliite Thelephora) ; subcartila- 

 ginous very broad liyaline, when dry resembling paper, milk- 

 white, circumference at first strigoso-radicate. Pers. Myc. Eur, 

 V. \,p. 150 T. pergammea^ Pers! I, c. Fr. El. v. I. p. 213. 



On fir-wood. Appin, Captain Carmichael. Rae Hill Woods, 



Dumfries, Professor Hoolier The specimens noted above and similar 



ones, gathered by myself in Scotland, differ from an authentic specimen 

 of Persoon now before me in having a less milky appearance, but the 

 hymenium seems to be less perfectly developed and the most advanced 

 individual differs very little. The circumference is very broad and almost 

 byssoid and shows only here and there a tendency to become spinuloso- 

 radiate. There is no doubt, however, that T. gigantea is the correct 

 name. Persoon makes several species of its different states. 



28. T, incrustans, Pers. (creejying Thelephora) ; eifused sub- 

 carnose rugose tuberculated pale, circumference somewhat 

 fibrous. Pers. Syn. p. 377. Fr. Syst, Myc, v.\, p, 448. — 

 T, sehacea, Pers. Myc. Eur. v. \, p. 135. 



On the ground and mossy trunks of trees ; not unfrequent, after 

 much rain. Braid Hermitage ; Autumn. Dr. Greville. King's Cliffe, 

 Norths., running-up tufts of Aira cccspitosa. Rev. M. J. Berkeley. — 

 *' 1 — 4 inches broad, soft, fibrous at the margin spreading over mosses 

 and culms of grass, small twigs or any thing that lies in its way, and 

 often so completely enveloping them as to make them resemble minute 

 stalactites. Hymenium smooth, very irregular and uneven, tuberculose 

 and papillose." Grev. I. c. Asci rather large, obovate, containing one 

 or two oblong sporules. 



29. T, cdlcea, Pers. (chalk-ivhite Thelephora) ; effused wax- 

 like closely adnate quite smooth even cracked when dry dirty- 

 white, circumference like the rest of the hymenium. Pers. Sy?i, 

 p. 581. Fr, Syst, 3Iyc.v. 1. p. 453. Grev. Fl. Ed. p, 411. 

 Fr.El.v. I, p. 215. 



" On decaying wood and trees. Frequent. Braid Hermitage, on a 

 dying elm. Autumn. — Unequal in thickness, effused, hard, extending 

 over several inches. Hpnenium white, discoloured in age, much cracked, 

 papillose, sometimes quite plane and smooth." Grev. I. c, 



SO. T. Samhuci, Pers. {Elder-wood Thelephora); effused 

 membranaceous thin, margin entire, liymenium white smooth 

 subpapillose. Pers. Myc. Eur. v, \.p. 152. Grev. Fl. Ed. p. 

 411. Scot. Crypt. Fl. t. 242. 



On elder and birch : very common. — The papillce. arise apparently 

 from the inequalities of the bark or wood on which it grows. 



31. T. ochrdceaiYr. (ochraceoiis Thelephora); effused very 

 broad thin, hymenium of an ochrey pale yellow, circumference
