18. Scliizophyllum, Fries. 



Pileus thin, without flesh, dry, flaccid and tough, tomentose, 

 sessile, fan-shaped ; gills radiating from the point of 

 attachment, forking, splitting along the edge, the split

SchizophyU'um, Fries, Obs., i., p. 103; Sacc, Syll. v., 

 p. 654. 



A small but cosmopolitan genus, most abundant in tropical 

 and subtropical countries. Characterized by the thin dry 

 substance of the entire fungus and the gills splitting along 

 the edge. Growing on wood.

Pileus very thin, dry, sessile, resupinate or usually at- 

 tached laterally and spreading like a fan, entire or variously 

 lobed ; pileus tomentose, greyish, 1-6 cm. broad ; gills radi- 

 ating from the point of attachment, forking, narrow, dry, 

 splitting along the edge, split surfaces minutely downy, grey, 

 then tinged purplish-brown ; spores hyaline, elliptical, apicu- 

 late, 5-6 x 4/x. 



On trunks, branches, and worked wood. Common in New 

 Zealand, and very general in tropical and subtropical regions, 

 becoming rare in colder regions. 



Very variable, sometimes resupinate and almost entire, 

 usually lateral and spreading from the point of attachment 

 in a fan - like manner. Sometimes cut into deep narrow 

 lobes.
