1 1 2 AGARICACEiE Leptonia 



simple, cartilaginous, tubular or stuffed, glabrous, sublustrous. Gills 

 adnexed or adnate, readily separating from their attachment to 

 the stem, not decurrent, variable in colour. Spores smooth or rough, 

 salmon. (Fig. 26.) 



Many of the species are gregarious and grow in troops, they are 

 mostly small, inodorous, except 517 and 524, and often beautiful in 

 colour, shades of light or dark blue or green being frequent. 



All grow on the ground except 521 ; they chiefly grow in mossy 

 pastures and marshy places. One non-British species — L. parasitica 

 Quel. — grows on the hymenium of 1370. They are most common 

 in rainy seasons. The species generally are suspected to be 

 poisonous.
