380. Pilacre faginettj Berk. & Br. Stipite nigrescente prui- 

 noso; capitulo subgloboso; sporis buxeis. Onygena faginea, Fr. 

 Syst. Myc. vol. iii. p. 209. On beech sticks, Spye Park, Wilts, 

 Aug. 1844, C. E. Broome. 



About 2 lines high. Stem 1| line high, pruinose, at length 

 brown or blackish. Head subglobose or turbinate, at first prui- 

 nose, umbilicate or (in our specimens) without any trace of an 

 umbilicus ; flocci branched, especially above, somewhat fastigiate, 

 more or less flexuous ; spores minute, broadly elliptic, with a 

 distinct nucleus. 



This appears to be nearly identical with specimens from Ohio 

 gathered by Mr. Lea, and with others from the Santee river. South 

 Carolina, collected by Mr. Ravenel. In these latter however, 

 though the outward resemblance is perfect, the flocci are not 

 fastigiate, but are strongly curled and frequently anastomose ; the 

 spores in either are exactly the same. We have seen no authentic 

 specimen of the plant of Fries. The structure of a very similar 

 fungus from Valais, for which we are indebted to Dr. Montague, 

 is totally different, resembling that of some compound Oidium. 

 The species has little in common with Onygena except external 

 appearance.

 highly magnified. 



381. Lycogala parietinum, Fr. /. c. vol. iii. p. 83. Didymium 

 parietinum, Schrad. Nov. Gen. p. 24. t. 6. f. 1. On damp paper, 

 old willow baskets, &c., King^s Cliffe. 



382. Didymium melanopus, Fr. /. c. vol. iii. p. 114. On bramble, 

 Speke Hall, Lancashire, 1842, M. J. Berkeley. 



383. D. tigrinum, Schrad. Nov. Gen. p. 22. t. 6. fig. 2, 3. P%- 

 sarum tigrinum, Fl. Dan. t. 1434. fig. 1. On mosses and Jun- 

 germannise, Bolton Woods, Wharfdale, R. Spruce, Esq., Dec. 

 1841. 



Our plant agrees precisely with the * Flora Danica ' species, 

 which has stouter stems than that of Schrader, but which Fries 

 considers identical. The same species has been kindly sent by 

 M. Lenormand from Falaise. 



384. D. congestum, n. s. Congestum, stipitibus submembra- 

 naceis hyalinis, vix botryosis ; peridiis obovatis elongatis ; sporis 

 atris floccis candidis variegatis. On dead leaves, grass, &c., King^s 

 ClifFe ; also in Upper Carolina.
