Exactly according with the Ceylon specimens, and with others from 

 Brazil. The Cuba plant is rather thinner, and that from South Caro- 

 lina has rather larger pores. The old specimens look very much like 

 the lumps of iron ore which occur in ferruginous limestone districts. 

 Young quickly grown specimens, with the pileus deeply and regularly 

 sulcate, are very pretty.

Hab. On dead wood. Khasia Mountains. (Dr. Hooker.) 

 Extremely hard and ponderous. Pileus 1 foot or more across, 4 

 inches long, decurrent behind, reflected in front, marked with a few 

 deep furrows, and very rugged and uneven, at first somewhat velvety: 

 substance dark purple-brown. Pores minute, stratose, but with layers 

 of the pileus interposed. 



A very distinct species, remarkable for its hard, dark-brown sub- 

 stance, resemWing exactly in colour Geranium phteum ; this is beauti- 

 fully zoned, especially where it is attached to the wood.

Corky, ponderous. Pileus 12 inches across, 4 inches long, obliquely 

 ungulate, decun'ent behind, deeply sulcate, rugose, covered with a resi- 

 nouSj red, laccate coat, which is in parts minutely wrinkled, and occa- 

 sionally cracked so as to expose the pale, wood-coloured, corky sub- 

 stance, which is very faintly zoned. Hymenium concave, wood-coloured. 

 Pores about -^-^ of an inch across, round or slightly angular, sometimes 

 elongated ; dissepiments rather thick ; edge rather obtuse, nearly even. 



This is closely allied to P. inarginatus^ but the pores are very much
