bulb, brown and clothed for three-quartersof its height with depressed velvety 

 pubescence, incrassated above where it passes into the pileus, white sprinkled 

 with furfuraceous particles; gills distant, broad in front, very decurrent be- 

 hind, whitish inclining to flesh color; interstices more or less reticulate. 



Allied to Marasmius insititius. Remarkable for its very decurrent gills. 



' The gills have anastomosed in these specimens to such an extent as to 

 form a solid wood mass. 



' Lentinus ciESPiTosus : eximie csespitosus; pileo piano, alutaceo, flbril- 

 lis brunneis adpressis sparsis ornato, margine incurvo ; stipite elongato, striate, 



griseo-albo, fibrilloso; lamellis integris, albis, longe decurrentibus. Pilei 



forming tufts of thirty or more individuals, one and a half to two inches across, 

 plane tough, yellowish-buff, clo.thed with close-pressed, brownish-red fibrillse ; 

 margin incurved ; stems three inches high, two lines thick, flexuous, tough, 

 striate, grayish-whit«, fibrillose, solid formed of fibres; gills white, very decur- 

 rent and attenuated behind, quite entire. A very curious species, with the 



habit of Agaricus contortus, Bull. It is easily distinguished from L. sitaneus 

 and its allies by its entire gills, 



3 Lentinus sulcatus : parvus, pileo primum subconico, demum hemi- 

 spherico, carnosulo, diffracto squamoso, sericeo-virgato, rufescente, margine 

 sulcato; stipite central!, brevi, solido, subconcolore, furfuraceo ; lamellis distant- 

 ibus, latuisculis, subcrassis, postice emarginatis, pailidis. Berk, in Hook. Bond. 

 Journ., V. iv. p. 301. Pileus not three-quarters of an inch broad, hemispher- 

 ical or nearly so, at first slightly conical, of a more or less rufous tint, broken 

 up into irregular scales, sericeo virgate (sometimes the scales are more or less 

 indistinct) ; fleshy; margin deeply sulcate, with the interstices darker, which 

 gives the pileus a very neat appearance; stem aboutthree-quartersof an inch 

 high, one and a half line thick, often slightly attenuated downwards, solid, of 

 the same color as the pileus, furfuraceous, sometimes confluent; gills distant,
