278 BRITISH FUNGI 



dingy cinnamon ; stem whitish, with an imperfect white, silky, 

 apical ring, ii-2j in. long. 



Our only Hcbdoma where the \'eil forms a ring on the stem. 



On naked soil. 



Naucoria 



Cap regular, more or less flesh}', conical or convex, then ex- 

 panded, edge at first incurved ; gills ne^'er decurrent ; stem 

 central, cartilaginous or more or less polished. 



Nearest to Galera, which differs in the edge of the cap being 

 straight, and not incurved when young, and in the thinner, often 

 striate cap. 



I. Pileus smooth (not floccose nor squamulose). 



* Gills adnexed or almost free. 



N. lugubris. — Cap i|-3 in. across, becoming wavy and gibbous, 

 pallid, then rusty ; gills free, broad, crowded, becoming rusty ; 

 stem 3-4 in. long, smooth, rooting, pallid, rusty below. 



On the ground among grass, moss, etc. 



N. festiva. — Cap convex, rather gibbous, even, glutinous, usually 

 brownish olive, dirty pale ochraceous when dry, about i in. across ; 

 gills free, ventricose, crowded, pale, becoming ferruginous ; stem 

 2-3 in. long, equal, narrowed and rooting at the base, smooth, 

 even, usually whitish, but sometimes variously coloured, hollow. 



A very fine species, but from the variable colours somewhat 

 difficult to define. Gills whitish at first, then sometimes olive, or 

 yellowish, or blood-red. Cap straw-colour, with an olive tinge 

 when dry. 



Among grass. 



N. arvalis. — Cap up to i in. across, tough, rather thick; convex,

 pulverulent, yeUowish, continued into a long rooting base. 



Allied to A^. semiorhicnlaris, but distinguished from this, and 

 every other known species, by the long rooting base of the stem. 



On the ground in cultivated fields, gardens, etc. 



iV. hydrophila. — Cap campanulate, then slightly expanded, 

 acutely umbonate, smooth, striate when moist, pale ochraceous tan 

 with a distinct tinge of green here and there, flesh very thin,
