300 AGARICACE^E Marasmius 



tinuous with but heterogeneous from the stem. P ileus arid, pliant, 

 more or less thin. Stem central, cartilaginous or homy, 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. Marasmius 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. 



Species 1391—1431 



A. Pileus fleshy-pliant, at length somewhat coriaceous, sulcate or 



wrinkled ; margin at first involute. Stem somewhat 

 cartilaginous. 



a. Scrotete. Stem solid or stuffed, then hollow, internally 



fibrous, externally cartilaginous and covered with villous 

 down which is easily removed. Gills separating-free. 



Stem woolly or strigose at the base. 1391 — 1393 



Stem naked at the base, often composed of twisted fibres. 



1394—1396 



b. Terg'mce. Pileus thinner than a in section, hygrophanous, 



even or striate. Stem rooting, tubular, cartilaginous, not 

 fibrous. Gills separating-free. 



Stem woolly downwards, smooth upwards. 1397 — 1400 



Stem wholly pruinato-velvety. 1401 — 1405 



c. Calopodes. Pileus convexo-involute, then plane or depressed. 



Stem curt, not rooting, inserted, often with a basal floccose 

 tubercle. Gills adnate or subdecurrent. 



Stem smooth and shining upwards, base simple. 1406 — 1410

margin at first straight and adpressed to the stem. Stem 

 horny, fistulose, sometimes stuffed, tough, arid. Mycelium 

 rhizomorphoid, corticate.

rooting or adnate by a dilated disc. 1415 — 1417
