It also occurs on Dicotyledonous trees. It grows out ^rst as a. 

 great cusl)ion of tissue, creainy-wliite in colour, gradually 

 becoming bracket-sliaped. Tlie margin is sterile, thick, and white 

 at first. The pores open rather late. When untouched the surface 

 of the hymenium is white, but is easily bruised, and turns dark- 

 greyish. When mature it sheds an enormous quantity of spores, 

 which cover logs or grass beneath the fructifications with a brown 

 coat. When fresh the fungus is almost spongy in texture, very 

 moist and extremely difficult to dry satisfactorily.

Tlie specinieas show the great variability in babit of this 

 species, from entirely resnpinate forms to tlie thick perennial 

 frnit bodies of a typical Fomcs. One of the specimens was found 

 on the Oil Palm (Elaeis gutneensis) ; Petch states that it does 

 not occur on Palms or Bamboos in Ceylon,* but it may be noted 

 in this connection that it has been received from Singapore grow- 

 ing on Bamboos, and has also been recorded on monocotyledons 

 in the Federated Malay States.

 Pileus of varying size, from 4 inches to a foot or more wide, and 

 u]) to 8 or 9 ins. across, applanate or sometimes more or less 

 triangular in section, but never truly ungulate. Surface covered 

 with a horny crust, at first deep umber-brown, velvety pubescent, 

 de^ly concentricall;^^ furrowed, later becoming blackish, rough. 

 and cracked. Margin paler, obtuse. Flesh radiating, colour of 

 flesh and tubes '' antique brown " (Eidgway 17 O.Y,, k). Pores 

 minute, deep brown. Spores brown, subglobose or elliptical, 

 5 X 4-4-5 ^. Setae usually present, abundant, 5 p. diameter, 

 projecting 12-15 p. Two specimens of this collection show no 

 setae, while possessing abundant spores. These may possibly be 

 conidial forms. The species is close to Fomes rimosus,\iVit is- 

 distinguished by the much more yellow-brown colour of the flesh, 

 the velvety surface, and the presence of setae in the pores 



In moist, high forest, growing at the base of trees, and possiblv
