62 AGARICUS. 



Tricholoma. Solitary or gregarious, scarcely csespitose. Stature always robust, obese, but 

 colour very changeable and variable. A. pileus cinereus, Sow. B. pileus 

 lilac Fr. C. pileus and gills white, stem violaceous Berk. In a very obese 

 form it has been found becoming wholly cinereous-livid. In late autumn taller, 

 becoming wholly fuscous, with a sulcate, fibrillose stem -as much as 10 cent. (4 

 in.) long, and very broad gills. 



In woods and pastures. Common. Oct.-Nov. 



Sometimes confounded carelessly with Cortinarius violaceus. It is some- 

 times difficult to distinguish brightly coloured specimens from A. nudus. 

 M.J.B. Edible. Known in England by the name of " Blewitts," which Bad- 

 ham conjectures means " Blue-hats." It is excellent when gathered in dry 

 weather. When wet it absorbs too much moisture. Spores sphaeroid-ellipsoid,

118. A. nudus Bull. Pileus about 7.5 cent. (3 in.) broad, be- 

 coming purple-violaceous then changing colour, rufescent, fleshy, 

 comparatively thin, convexo-plane then depressed, obtuse, even, 

 smooth, with a pellicle which is moist and manifest in rainy 

 weather; margin inflexed, thin, naked ; flesh thin, pliant, coloured. 

 Stem about 7.5 cent. (3 in.) long, 12 mm. (% in.) thick, stuffed, 

 elastic, equal, almost naked, mealy at the apex, violaceous then be- 

 coming pale. Gills rounded then decurrent (on account of the 

 depressed pileus), crowded, narrow, of the same colour as the 

 pileus or deeper violaceous, but soon changing colour, at length 

 rufescent without the least tinge of violet. 



Always thinner than A. personatus, with a pleasant acid odour. Often 

 confounded with A. sordidus. 



In woods, chiefly among pine. Frequent. Sept.-Nov. 



Brighter coloured than A. personatus M.J.B. Not recommended as edible.
