firmly oemented, outer wall of a hill. There i- no reason 



however why it should not develop from the combs of the 

 subterranean base. 



Though easily recognizable, it varies greatly in size, form, 

 and colour, and hence it is not surprising that it has received 

 at least six names, especially as these have with one exception 

 been bestowed on dried specimens. Gardner sent two forms 

 to Berkeley, both apparently immature, for Berkeley named one 

 Lentinus cartilagineus and the other Armillaria eurhiza. 

 Twenty-five years later, Thwaites sent the first form again 

 to Berkeley : this time it was named Collybia spnrsibarbis. 

 it is really a pink-spored agaric, as Holtermann (7) decided 

 when he named it Pluteus Rajap, the specific name being that 

 by which it is known to the Malays. 



In its most frequently occurring form it is at first sight a 

 Pluteus (PI. XI. and XII. A). Thepileusis at first conico-cam- 

 panulate, then almost plane with a strongly developed umbo, 

 smooth or radially rugose, glabrous, viscid when moist . 

 blackish brown at the umbo becoming gray towards the edge, 

 sometimes wholly livid brown, sometimes gray. The pileus of 

 smaller specimens may be wholly pale brown when dry. The 

 margin is very irregular, and the pileus is usually split in 

 ■evetrai places almost to the centre. The outline may be 

 circular, oval, or irregularly lobed, the greatest irregularity 

 occurring in the wet seasons. The white flesh is differentiated 

 f 1 1 on the stalk and is very thin towards the margin. The 

 dtt meter varies from 6 to 15 centimetres. The gills are 

 tree equal, crowded, about 5 mm. broad, at first white, then 

 pink from the spores, and finally pinkish yellow in decay. 



The solid stalk is on the average about .'JO centimetres 

 long and l-L' centimetres in diameter. From one-thud to 

 one-fifth of t hi i above ground. Of the part below ground. 

 the low( : halt or sometimes the whole, is black. 

 Upper white portion is equal, often twisted, fibrous.
