172 DECADES OF FUNGI. 



zones, so as to resemble the section of some dicotjledonous wood; mar- 

 gin arched. Stem 2-3 inches high, 1-2 lines thick, tolerably regular, of 

 the same colour as the pileus, pruinose, Hymenium cinereous-umber ; 

 pores punctiform ; edge tomentoso-grauulated ; trama slightly grooved. 



A very beautiful species. The pileus is rather dull in appearance ; 

 but possibly when growing may have a shining sericeous aspect. 



547- P. (MesopuB) omphalodes, n. s. ; pileo orbiculari crassiusculo 

 convexo umbilicato rugoso zonato hepatico ] stipite gracili quandoque 

 furcato; hymenio cinereo ; pons punctiformibus, acie pruinosa ; trama 

 impressa; contextu albo zonato. Spruce, n. 32, 194. 



Hab. On the ground, more rarely on trunks, in Caatingas. Panur^. 



Pileus 1-2 inches across, moderately thick, convex, umbilicate, 

 liver-coloured, sometimes with a yellowish tinge, rugose and lineate ; 

 edge entire or crenate. Stem 4-6 inches high, 1-2 lines thick, some- 

 times forked, pale brown, pruinose, rooting- Hymenium concave, 

 cinereous ; pores punctiform, their edge pruinose, with the trama 

 slightly grooved, terminating abruptly. The stem sometimes sinks 

 deeply into the hymenium. 



Those individuals with a yellowish tint have a smoother pileus and 

 are more frequently zoned ; the hymenium too is not cinereous ; still I 

 believe them to be the same species, because there is a specimen pre- 

 cisely intermediate, with the colours of the former and the sculpture of 

 the latter, and both are intermixed. The variety may be called F. 

 omphalodes, VBx.fulvaster. 



548. P. (Mesopus) ocellatusy n. s.; pileo orbiculari convexo hepatico 

 zonato sublaBvi radiatoque rugoso, opaco L sericeo, nitido ; stipite gra- 

 cili ; hymenio convexo cinereo ; poris ocellatis ; trama leviter sulcata ; 

 contextu sericeo cinnaraomeo. Spruce, n. 193. (Tab. X. fig. 3.) 



Hab. On the ground in Caatingas. February, 1853. Panure. 



Pileus 1^-3 inches across, convex, umbilicate, liver-brown, some- 

 times shining, sometimes opaque, even or radiato-rugose, zoned, con- 

 vex, thin, coriaceous. Stem 4^-7 inches high, J-l line thick, sometimes 

 compound above, umber, pruinose. Hymenium cinereous ; pores punc- 

 tiform, with a white edge ; trama slightly grooved. Substance of pileus 

 silky, bright cinnamon-red. 



This could scarcely be distinguished from P. omphalodes without at- 

 tending to the texture, which is totally different. (Tab. X. fig. 3. P. 

 ocellalus, nat. size,)
