MAEASMIUS. Fries. 



Pileus regular, thin, tough and pliant ; gills pliant and 

 'gather tough, somewhat distant, variously attached or free, 

 edge thin and quite entire, often connected by veins ; stem 

 cartilaginous or horny, continuous with the substance of the 

 pileus, but differing in structure. The species are tough, 

 dry, shrivelling and drying up (not putrescent), and ex- 

 panding when moistened. 



Marasmius, Fries, EjDicr., p. 372 ; Cke., Hdbk., p. 344. 



A very distinct genus, but distinguished more especially 

 by biological characters, and differing from Collyhia and 

 3Tycena, its nearest allies, by not deliquescing at maturity, 

 "but drying up and again assuming the original form when 

 moistened. The species are comparatively rare in temperate 

 regions, but are numerous in the tropics, where the gills are 

 often narrow, very distant, and connected by prominent 

 -veins. Many species have a smell resembling garlic. 



.Mjst species grow on wood, branches, or leaves. 



ANALYSIS OF THE SPECIES. 



I. COLLYBIARII. 



Flesh of pileus pliant, at length somewhat coriaceous, 

 .grooved or wrinkled, margin incurved at first; stem some- 

 • what cartilaginous ; mycelium woolly, absent in only very 

 ifew species. 



A. Scortei. 



Stem solid, or stuffed then hollow, fibrous inside, outside 

 the cartilaginous cuticle is covered with down ; gills 

 :_6'"parating from the stem and becoming free.
