memoir which ought to be well studied by every investigator 

 of the more obscure phenomena of Cryptogamic plants*. 



87. Peziza taniosa, SchracL, Journ. Bot. 1799, ii. p. 64. 

 Two specimens of this very curious species, which appears not 

 to have been found since the date given above, occurred at 

 King's Clitic- early in the present autumn, upon soil overrun 

 with Thelephora incrustans. As it Is of such rare occurrence 

 I have thought it right to give a figure. 



Plate VII. tier. ~. a, Peziza saniosa, nat. size; b, vertical section; c, asci 

 with their paraphyses and Bporidia magnified ; d, a single sporidium highly 

 magnified. 



88. Peziza melaloma, A. and S. p. 33G. t. 2. f. 5. South- 

 wick, Norths, abundantly on ground where a fire had been 

 made, after the first autumn rains. 



*89. Peziza rhabarbarina, Berk., Eng. Fl. vol. v. part 2. 

 p. 197. This is clearly the same with Montagne's Pez. Arden- 

 nensis, Ann. de Sc. Nat. n. s. vol. v. p. 287. If it be retained 

 in the genus Peziza the former specific name must be pre- 

 served. But there is reason to believe that M. Desmazieres, 

 who finds it in the north of France, is correct in referring it to 

 the genus Patellaria. He proposes in this case to give it the 

 specific name of Rosacearum. The sporidia are longer than 

 Montagne figures them. He is correct in representing para- 

 physes, though he does not seem to have ascertained their 

 form, which is linear with spathulate tips. 



*90. Dacrymyces Urticce, Fr. Syst. Myc. v. 2. p. 251. Fu- 

 sarium Tremelloides, Grew Sc. Cryp. Fl. t. 10. Eng. Fl. vol. 

 v. part 2. p. 355. The structure of this fungus is not to be 

 ascertained clearly without high magnifying powers. On a 

 slight inspection with rather low powers the structure some- 

 what resembles that represented by Dr. Greville, but a close 

 inspection will show that the mass consists not of long fusi- 

 form sporidia but of erect branched subdichotomous threads, 

 which consist of articulations not to be seen without a very 

 nice adjustment. The structure is very nearly that of Dacry- 

 myces stillatus, nor does it differ sufficiently to warrant the

 found in Meyen's Report of the Progress of Vegetable Physiology, in the 

 year 183G. Philosophical Magazine, vol. xi. p. 386.
