170 DECADES OF FUNGI 



Pileus 2 1 inches across, orbicular, sometimes attached behind, broadly 

 umbilicate, marked with a few radiating ridges and numerous raised 

 lines, brown, painted with many darker zones ; margin arched. Stem 

 3 inches high, \ of an inch thick, straight, nearly even, brown, prui- 

 nose ; hymenium white ; pores punctiform. 



A very beautiful and distinct species. 



542. P. (Mesopus) partiius, n. s. ; pileo tenui coriaceo infundibuli- 

 formi e basi ssepius sursum diviso zonato rufo-variegato lineato, mar? 

 gine lacerato-lobato ; stipite elongato umbrino pruinoso ; hymenio niveo ; 

 poris mediis acie prominente. Spruce, n. 20, 200. (Tab. X. fig. 1.) 



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



Pileus 2-3 inches across, thin, coriaceous, infundibuliform, split up- 

 wards from the base, and sometimes entirely divided, variegated with 

 red-brown tints, zoned, rough with fine lines j margin lobed and 

 jagged. Stem 4-6 inches liigh, 1^ line thick, umber, opaque, finely 

 pruinose. Hymenium snow-white when fresh, acquiring a slight ochra- 

 ceous tinge in drying. Pores ^ of an inch across, angular ; dissepiments 

 rather rigid ; edge projecting ; sometimes the edges of several pores are 

 united and raised above the transverse partition so as to form linear 

 compound sinuses ; where they arc most perfect they are hexagonal. *

The pileus is 5 inches across, and split up from the very base so as 

 to form a large wedge-like expansion. Though on a larger scale, I 

 can see no distinction. (Tab, X. fig. 1. P, partitas, nat. size.) 



543. P. (IVIesopus) renatus, n. s. ; pileo ex infundibuliformi laterali, 

 lobato vel subintegro crenulato tenui rigido-papyraceobadio rufo-lineato 

 rugoso glabro; stipite elongato umbrino pruinoso; hymenio albido, 

 poris augulatis parvis. Spruce, n. 169. 



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



Pileus 1-2 inches broad, infundibuliform, at length lateral, of a rich 

 red-bay, slightly zoned and variegated, rough with little raised innate 

 lines, sometimes so much so as to be rugose ; thin, rigido-papyraceous. 

 Stem 4-6 inches high, ^-1 line thick, pale umber, pruinose. Hyme- 

 nuim pale umber. Pores tender when young, gradually expanding into 

 regular hexagonal cavities ^\^ of an inch broad, sometimes produced 

 on a part only of the hymenial surface, as if they were a secondary 

 growth; edge regular, entire.
