The Naturalist. 



specimens of Limncea peregra from Coverdale, which he found in damp 

 grass in swampy places near the river. — Wm. Denison Roebuck, Leeds. 



Leptoscijphus interruptus (Nees). — This very rare hepatic has lately 

 been found in Cheedale, Derbyshire, by Mr. G. A. Holt, of Manchester. 

 In Dr. Carrington's British Hepaticfe," no mention is made of any 

 locality in Derbyshire for this species ; it is, however, given in the 

 London Catalogue of British Mosses and Hepatics " for province 8, which 

 includes Derbyshire. Can any reader say if this species has previously 

 been found in Derbyshire, and where ? or is Mr. Holt's discovery new to 

 the county? — W. H. P. Since sending. the above, with reference to 

 Leptoscyphus interrnjjtus (Nees), 1 find that it is recorded in Synopsis 

 Hepaticarum," (1844). In AngUa (Matlock, Derbyshire), leg., W.

Ehizomorpha suhcorticalis in Yorkshire. — Mr. C. C. Hanson, of West 

 Yale, has sent us a curious specimen of fungoid vegetation to be named. 

 He writes us that he found it ' ' on stripping the bark off a dead maple 

 tree ; it was between the bark and the wood, but adhering to the wood, 

 on which it left a beautiful imprint, and was many yards in length." 

 Being unable to name it ourselves, we sent it to Mr. J. G. Baker, F.R.S., 

 of Kew Herbarium, who determines it to be the celebrated Ehizomorpha 

 suhcorticalis (see Berkeley's Outlines, p. 42), and that it is an abnormal 

 condition of the mycelium of various species of fungi of the genera Poly- 

 porus and Xylario., vegetating under the bark. In Sir J. E. Smith's 

 Eng. Flora, by Sir W. J. Hooker, vol. v. pt. 2, p. 235, it is referred to 

 Xylaria (S2jhcEria) Eypoxijlon, where it is further remarked — ''though, 

 as Fries observes, every production so named is not to be referred to this 

 species. Withering long ago perceived the connection. The editor of 

 the last edition is, however, most probably wrong in referring it to 

 Rh. imperialis. I perfectly agree with that most judicious author, 

 M. Fries, as to the desirableness of excluding from the list of fungi all 

 such doubtful productions. Nothing, however, can be more interesting, 

 and, as regards the physiology of these plants, more instructive, than the 

 correct reference of such abortive forms to the perfect species." — We 

 should be glad to learn whether any other observer has come across any 

 specimens of this curious production, and under what circumstances. —

NOTICES OF BOOKS.—" On Cephalozia (a genus of Hepatic?e) : 

 its Sub-genera and some Allied Genera : By Richard Spruce, Malton. — 

 Printed for the Auther, 1882." — This, the latest work of a distinguished 

 naturalist and explorer, will be studied intently by all who are interested 

 in the Hepaticse, for in it are given some of the results of many years of 

 careful observation in difierent parts of the world : whether in the woods, 

 dales and heaths of his native county ; or in the South of Ireland bota- 

 nizing with the late Dr. Taylor ; or rambling in the Pyrenees with his 

 friend Dr. Southby ; or alone in the wilds of South America ; supple- 

 mented by years of quiet microscopical study, only interrupted by painful
