178 AGARICUS. 



Pleurotus. muscigenus or C. lobatus. A is the primary form described in Fr. Syst. Myc. 

 C, however, may be taken as the typical form of the species. 



On decayed wood, lawn, &c. Rare. Aug.-Dec.

1 1 1. RESUPINATI. 

 * Pileus fleshy, uniform. 



387. A. porrigens Pers. Wholly shining white. Pileus 2.5-10 

 cent. (1-4 in.) broad, at the first resupinate, sessile, adnate behind, 



forming excentric orbicular shields, with the gills concurrent in 

 an umbilicus, soon however extended laterally, ascending, ear- 

 shaped, narrow at the base, dilated above ; otherwise fleshy, tough, 

 flaccid, at length undulato-lobed, even, somewhat smooth, but 

 more or less tomentose towards the base ; flesh thin, compact. 

 Gills at first concurrent, somewhat veined, decurrent to the base 

 when the pileus is extended, thin, crowded, linear, very narrow, 

 sometimes divided. 



Inodorous, insipid, when full grown often imbricated in the form of steps. 

 It at length resembles A. petaloides. 



On stumps, chiefly pine. Frequent. Aug.-Oct.

388. A. septicus Fr. Wholly shining white. Pileus 2-10 

 mm. (1-5 lin.) broad, slightly fleshy, villous, at the first resupinate, 

 attached to the wood, then furnished with a short (2-4 mm., 1-2 

 lin.) incurved, villous stem, which becomes erect and at length 

 vanishes, so that the reflexed pileus then appears sessile, with 

 flaxy rootlets. Gills at first converging round the rudiment of a 

 stem, comparatively broad, somewhat distant. 



Very small, so changeable in form that it is difficult to recognise the same 

 individual in different stages of its growth. In form, and flaxy rootlets of the 

 stem, it is chiefly to be compared with A. byssisedus. It is smaller, however, 

 and more fleshy, and is wholly (also the spores) shining white. It resembles 

 A. variabilis, but the gills do not change colour on account of the spores being 

 white. 



On decayed wood, fungi, &c. Frequent. June.-Oct. 



Name septicus, putrefying. From its growing on rotten wood. Fr.
