176 AGARICUS. 



Pleurotus. The stem becomes at length obsolete, and the pilei overlap each other. 

 Name- mitis, mild. From its insipid taste. Pers. Syn. p. 481 (but not the 

 fig. in Obs. Myc.) Fr. Monogr, i. p. 249. Hym. Eur. p. 177. Berk. Out. p. 

 136. t. 6.f. 9. C. Hbk. n. 122. Illust. PL 258. b. S. MycoL Scot. n. 218. 



381. A. gadinoides Sm. Whole plant white. Pileus rather 

 fleshy, tender, dimidiate, clothed with fine adpressed flocci, hygro- 

 phanous, with no gelatinous upper stratum. Stem minute, lateral 

 or none. Gills somewhat crowded, slightly branched. 



Allied to A. mitis. Spores 8x3 mk. 



On tree-fern stems. Chelsea, 1872. May. 



Name from Gadinia, the name of a beautiful white bivalve. Smith in 

 Journ. Bot. 1873. p. 65. C. Illust. PI. 276. a. 



382. A. limpidus Fr. Pileus about 2.5 cent, (i in.) hyaline- 

 white when moist, shining white when dry, slightly fleshy, obovate 

 or reniform, horizontal, even, smooth, hygrophanous, and without 

 a viscous pellicle, margin very thin, shortly inflexed. No separate 

 stem, but the pileus is narrowed behind into a stem-like base. 

 Gills thin, crowded, decurrent at the base, white. 



It cannot be confounded with any other, and can only be compared with A. 

 mitis. Its habit and substance are almost the same as those of A. mitis, but 

 it is somewhat sessile and wholly shining white. The rudimentary stem is 

 neither squamulose nor villous. The gills are decurrent on the stem-like base, 

 but end determinately. Taste mild.

383. A. reniformis Fr. Pileus 6-10 mm. (3-5 lin.) broad, 

 cinereous, slightly fleshy, horizontal, reniform, plane, emarginate 

 behind, the regular margin entire, spreading; flesh very thin, 

 somewhat gelatinous, diaphanous. Stem a very short villous rudi- 

 ment. Gills running cut from the stem-like tubercle, and diver- 

 gent, thin, linear, grey.

384. A. lauro-cerasi B. &. Br. Pileus rather more than 2.5 

 cent, (i in.) broad, brown, oyster-shaped, sulcate, cuticle very 

 thin. Stem obsolete. Gills connected by veins. 



The cuticle is extremely thin, and gives way at the furrows, so as to expose 

 the substance of the pileus.
