262 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



viscid, ivory-white. Stem j-1 incli high, not a Hne thick, in- 

 crassated upwards, smooth, soHd, pure white. Gills thick, broad, 

 arched, decurrent, very few and distant, with a few shorter ones 

 intermixed. The whole plant exhales a strong musky smell like 

 that of Russian leather, or Potentilla atrosanguinea,\ihic\i it some- 

 times retains for years. 



The only species which approaches very near to this is Ag. 

 ptychophyllus, Corda. It is at once known by its delightful 

 odour.

 Aug. 1838. 



The determination of the species of this genus is surrounded 

 with many difficulties. This and the two following, gathered 

 near Bristol, being clearly characterized and exactly described by 

 Fries, we venture to give as certain contributions to the list of 

 British Fungi. Other species may be added when strictly de- 

 termined. The present is known by its very acrid taste and free 

 gills, between which and the stem is a distinct channel as in the 

 Pluiei. 



334. R. Integra J Fr. Ep. p. 360. Leigh Wood near Bristol, 

 Aug. 1848. 



Distinguished by its mild taste, its at length sulcate and tu- 

 berculated margin, its white stem and its gills which gradually 

 assume a pale dirty yellow hue. 



335. R. aurata, Fr. /. c. Leigh Wood, Aug. 1848. 



A most splendid species, distinguished by its golden yellow 

 shining pileus and yellow margined gills. It is equal in beauty 

 to Ag. muscarius. 



336. Cantharellus Browniiy n. s. Ochraceo-albus ; pileo tenui 

 convexo subumbonato; stipite gracili, farcto; plicis subdistan- 

 tibus angustissimis obtuse decurrentibus. Amongst grass (to 

 the roots of which it was attached) in the park, Hitchin, Mr. Isaac 

 Brown and Mr. W. Dawson, Oct. 1844. 



Whole plant of a pale ochraceous cream-colour. Pileus orbi- 

 cular, thin, convex, subumbonate, half an inch across, sometimes 

 rather larger, obscurely silky. Stem slender, l|^-2 inches high, 

 scarce 1 line thick, nearly equal, subfurfuraceous, furnished with 

 a little white fibrillose mycelium at the base, which sometimes 

 forms a small earthy ball, rather tough, stuffed. Folds linear, 

 •very narrow, sometimes slightly forked, obtusely decurrent ; in- 

 terstices smooth ; occasionally quite obsolete except towards the 

 margin. Hymenium nearly white. 



There is no described species allied to this except Canth. au- 

 rantiacus, which approaches to it by means of its white variety. 

 It is a very neat and beautiful fungus, with very much the habit 

 of Ag. hemisphceincuSj and with the stem stuffed as in that species.
