pores (cfr. Note 176, Letter 53). Setae dense, rather short and thick, 



sometimes blunt, projecting 30-35 

 mic. Spores (B) elliptical, pale, 

 3x5 mic. 



This is a frequent plant in 

 Brazil, and well represented in the 

 museum. \Ve have specimens 

 from Rev. C. Torrend. 



HYDNOCHAETE FERRU- 

 GINEA. -- Resupinate, thin, 

 with byssine margin, ferruginous. 

 Setae abundant. Spores globose, 



Fig. 767. 



Teeth small, >^ mm. subulate. 

 3-4 mic. verrucose, ferruginous. 



It was described from Brazil by Father Rick. Unknown to me. 

 As it has colored spores, Professor McGinty proposes for it a "new 

 genus," Phaeohydnochaete. Those who recognize the other "Phaeo" 

 genera cannot consistently refuse to adopt it. 



HYDNOCHAETE JAPONICA (Fig. 768). Resupinate, with no 

 distinct margin, hard, rigid. Context thick, dark mummy brown. 



Fig. 768. 

 Hydnochaete Japonica. Showing section, surface, also spines, the latter enlarged 6 diameters. 



Imbedded in the context are rigid, thick, deeply colored setae, similar 

 to those found in Fomes pachyphloeus (cfr. Fig. 600, Fomes Synopsis). 

 Surface tubercular, with small, dense, rigid tubercules, paler (brown) 

 than the context. Tubercules densely covered with setae, projecting 

 40 to 50 mic. Spores not found, no doubt white.
