300 AGARIC AC E& Marasmius 



tinuous with but heterogeneous from the stem. PUeus arid, pliant, 

 more or less thin. Stem central, cartilaginous or horny, absent in 

 1431. Gills usually simple, pliant, somewhat distant, edge acute, 

 entire. Spores white. (Fig. 66.) 



The species are commonly small, thin and epiphytal, those which 

 appear to grow on the ground are generally on putrid leaves or 

 roots of grasses ; many have a strong odour, sometimes fetid, or of 

 garlic, never of meal. Marasmins is closely allied to Collybia, but 

 the true Marasmii shrivel in dry weather and revive in rain. Some 

 are edible, others are esteemed for flavouring, 1391 is dangerous.
