86 AGARICUS. 



Clitocybe. brick colour or Vw er-rufescent, ^es/zy, somewhat fragile, in no wise 

 flaccid, convexo-plane, obtuse, then infandibuliform and undulated, 

 even, very smooth, moist when fresh, but never guttate, sloping- 

 towards the margin, varying excentric ; flesh not thick but com- 

 pact, someivhat of the same colour as the pileiis. Stem sometimes 

 stuffed, commonly hollow, hence compressed, externally with a 

 slightly rigid outer coat, not elastic, without a bulb, smooth, 

 whitish, somewhat rooted and white-villous at the base. Gills 

 truly decurrent, scarcely 4 mm. (2 lin.) broad, crowded, simple, 

 whitish, but then of the same colour as the pileus at the edge. 



Odour peculiar, slightly acid. It corresponds with A. infundibuliformis 

 Schasff'., and like it presents two forms — one, which is at the first gibbous, being 

 the rarer ; the other, which is destitute of an umbo, being the more frequent 

 and nearest to A. splende?is. It differs from A. gilvus in its entire nature. 

 The primary form is regular, solitary, with the stem attenuated upwards, and 

 of the same colour as the pileus. More frequently it is somewhat ccespitose, 

 with the stems curved and compressed, and the pileus very obtuse, unequal, 

 and somewhat repand. A. lobatus Sow. is a luxuriant condition of this ; stem 

 thickened upwards, pileus somewhat date-brown and undulato-lobed. 



In woods, chiefly pine. Frequent. Aug.-Nov. 



When dry the pileus has a very smooth oiled appearance. Spores 3 mk.

172. A. flaccidus Sow. — Pileus 5-7.5 cent. (2-3 in.) broad, 

 tawny-ferrugi7ious, shining, not becoming pale, slightly fleshy, 

 tough, orbicular, _^<3:^aV/ (especially when dry), at the first u?nbili- 

 cate, always without an umbo, then infwidibttliforjn, the spreading 

 border slightly convex, smooth, even, rarely rimuloso-squamulose ; 

 flesh thin, pallid, somewhat fragile when fresh, flaccid however 

 when dry. Stem curt, 2.5-5 cent. (1-2 in.) long, thin, 4-6 mm. 

 (2-3 lin.) thick, somewhat hollow, elastic, tough, somewhat equal, 

 polished, naked, rubiginous-ferruginous, thickened and villous at 

 the base. Gills deeply, almost obconico-decurre?it, remarkably 

 arcuate, very crowded, narrow, scarcely 2 mm. (i lin.) broad, 

 simple, whitish then becoming yellow. 



Gregarious, forming rings, the stems often growing together under the soil, 

 but also solitary, regular. The gills become yellow sometimes wholly, some- 

 times only at the edge. Allied to A. inversus. 



In woods. Frequent. Sept.-Nov.
