204 DECADES OF FUNGI. 



dentatis. — In the Serra Mey, British Guiana (Rob. Schomburgk, a 

 single specimen.) 



3. Tachia BchomlnrgYiana ; foliis quintuplinerviis, calyce 5-alato, 

 laciniis lanceolatis tubo longioribus (demum fere pollicaribus). — On the 

 mountains covered with thick forest between Eoraima and the Cuyuni, 

 at an elevation of 3000 to 4000 feet (Rob. Schomburgk, a single spe- 

 cimen. Rich. Schomburgk, n. 1546). 



The three species closely resemble each other in general habit, m 

 the shape of the leaves, and in the size of the yellow flowers.

461. Cyathus llooken^ n. s. ; peridio cyathiformi pallido intus 

 stria to vel omnino Isevi; sporangiis amplis ; integumento tenuissimo, 

 cortice nigro, sporis minutis. 



Hab. On dead wood, Khasia. On moss and lichen covered with 

 sawdust, KoUoiig rock, Khasia HiUs, 1850. (Dr. Hooker.) 



3 5 



Crowded, pale wood-coloured. Peridia cyathiform, sessile or obso- 

 letely stipitate, clothed with squarrose acute scales, obscurely striate 

 within or quite smooth. Sporangia 1 line broad, wrinkled. Integu- 

 ment very thin ; bark nearly black ; hyraenium thick. Spores obovate, 

 j^^ of an inch long. 



The spores of this are smaller than in any species except C, micro- 

 sportis. It is certainly very distinct. 



462. C. Umodensis, n. s. I albidus, campaniformis, basi angnstata, 

 subsessilis, superne late apertus, striis plane destitutus, extus fascicula- 

 to-tomentosus, margine stellato-ciliato ; sporangiis umbrinis Isevibus, 



Hab. On dead wood, Sikkim. Lachen, 12-13,000 feet. (Dr. 

 Hooker.) 



Dirty white. Peridium rather thick, clothed with spongy down 

 collected in little fascicles, quite smooth within ; margin fimbriated with 

 the projecting hairs, about 4 lines high, and scarcely so much wide.
