BRITIBH FUNGI. 119 



Lactarius exsuccus. Smith. 

 Pilous clothed with adpressed down, fleshy, depressed, with an 

 involute margin ; gills decurrent, white, shaded with verdigris, 

 connected by veins and forked; stein white, very short, clothed 

 with adpressed down ; whole plant rigid and brittle, milkless. — 

 Smith, Jour. Bot., 1873,/?. 33G. Lact. vellereus var. /3. exsuccus. 

 Fries, Sys. Myc. i. p. 77. Buxb. Cent. iv.,t. 4. 

 In pine woods, &c. 



Smith observes that this plant can no longer be considered a 

 mere variety of L. vellereus. The fruit of the two plants, as well 

 as the general habit is very different. 



Lactarius minimus. Smith 

 Journ. Bot., 1873, p. 205, with figs. 

 In a small wood. Abergavenny. Oct., 1871. 



Russula subf ceteris. Smith. 

 Pileus bullate, subviscid, disc fleshy, margin submembranaceous ; 

 gills thick, distant, and branched ; stem not so stout as in R. fcetens, 

 smaller, odour somewhat disagreeable ; taste slightly acrid. — Smith, 

 Journ. Bot., 1873, p. 337. 

 On the ground. 



Smith observes that this is the plant referred to by Fries in Sys. 

 Myc, i., p. 58, as a variety of R.fragilis, but that plant has crowded, 

 thin, and generally entire gills, whilst those of the present plant 

 are thick, distant, and branched. It is much nearer R. fcetens. 

 Nyctalis caliginosa. Smith. 

 Pileus very fleshy, white when dry, flocculoso-pruinose, when wet 

 marked with colours (as in Ag. butyraceus) ; margin involute, 

 slightly exceeding the gills, gills thick, branched, decurrent ; stem 

 solid, flocculoso-pruinose, base naked ; odour and taste rank and 

 disagreeable (like Polyporus squamosus). Smith, Jour. Bot., 1873, 

 p. 337. 



Amongst earth and dead leaves. Highgate. 

 Closely allied to N. parasitica, but at once distinguished by its 

 truly decurrent gills and other characters. 



Marasmius terginus. Fr. 

 Inodorous. Pileus rather fleshy, convex, then plane, obtuse, 

 shining, becoming whitish ; stem fistulose, smooth above, shining, 

 pallid, reddish below, villous and rooting ; gills seceding, then free, 

 rather crowded, narrow, pallid. — Fries, Sys. Myc, ii., 128. Fries, 

 Epicr., p. 377. B. $ Br. Ann. N. H., 1361. 

 Amongst leaves in a wood. Batheaston. Nov. 

 Pileus T 5 ^- in. broad, faintly striate, of a pale reddish brown, 

 darker in the centre; stem about 3 in. high, ^ line thick, smooth, 

 pale-brown, satiny ; gills reddish-ochre, adnate by a tooth, but 

 sinuated, moderately distant.
