 Pers. Syn. p. 655. Fr. Sf/st. 3Iijc. v. 2. p. 132. 



On stumps, especially on the inside of the bark. Winter. Very 

 common in Northamptonshire, Rev. M J. Berkeley — Gregarious, ex- 

 tremely minute, very thin, soft, often irregular, white at length turning 

 yellowish in patches. When dry it resembles minute grains of white 

 sand scattered over the brown bark. 



52. P. sulphur ea, Pers. (sulphur-coloured PezizaJ; sessile 

 subglobose strigoso-tomentose sulphur-coloured, disc pallid. 

 Pers. disp.p. 33. Fr. Syst. Myc. v. 2. p. 104. Scler. Sued 

 n. 453. Grev. So. Crypt. FL t. 83. Fl. Ed. p. 420.— P. hyd- 

 Qioeidea, Purt. v. 2 4- 3. n. 1049. 



On stems of herbaceous plants, especially nettle. Spring. Common. 

 — Often brown when dry. 



53. P. plano-umhilicdta, Grev. (ivhite wnhilicated Peziza) ; 

 small sessile gregarious, wliole plant white globoso-concave at 

 length quite plane ciliated with horizontal white hairs at the 

 margin, hymeniuni gently unibilicated. Grev. Fl. Ed. p. 420. 



On the decayed stems of Urtica dioica. Summer and autumn. 

 Capt. Waiich.—Oi the same size as the preceding, wholly white, re- 

 markably plane with a small dimple in the centre of the hymeniurn, 

 which in old age assumes a yellowish tinge. The external surface is 

 covered with white hairs which form a beautiful ciliated margin, not 

 in the least raised. The margin is so regular, that, if there had been 

 fewer ciliae, it might have been called pectinate." Grev. I. c. 



54. P. villosa, Pers. (villous gramdiforni Peziza); sessile 

 minute persistent globose villous white orifice subconnivent. 

 Pers. Syn, p. 655. Fr. Syst. Myc. v. 2. p. 104 — P. granuli- 

 formis, Pers. Syn. p. 651. Grev. Fl. Ed. p. 421. Johnst. FL

 garious very minute, cups farinoso-subtomentose (subhirsute, 

 Grev.) pale umber. P. nidulas, Grev. Fl. Ed. p. 420. Johnst. 

 Fl. Berw. v. 2. p. 149. 



On the stems of larger herbaceous plants. Autumn. Near Edin- 

 burgh, Dr. Greville. Near Berwick on the cow-parsnip, Dr. Johnstone. 

 — Dr. Greville's plant is certainly, from a comparison of authentic 

 specimens with those published by Mougeot and Nestler, not the plant 

 of those authors, as Dr. Johnston rightly suspected. It differs in 

 colour, in the nature of the external coat, and above all in its being 

 nearly free, while that is almost immersed. It appears to approach 

 near to P. micacea, Pers., but is of a firmer consistence, insomuch 

 that Dr. Greville describes it as coriaceous. Several species undoubt- 

 edly belonging to this subgenus, collected by Captain Carmichael, appear
