POLYPORUS DISCOIDEUS (Fig. 503). Pileus thick, fleshy, 

 with a smooth brown cuticle. Stipe excentric (or sub-lateral) short, 

 thick. Pores probably white when fresh, discolored in the dried speci- 

 mens, minute, round. Spores not found by me.

Polyporus discoideus (small specimens). 



This is a tropical American species, originally from Cuba. Recently speci- 

 mens have been sent me by Rev. Rick, Brazil, from which our figure (503) 

 has been made. The original specimen from Cuba was larger, about four inches 

 in diameter. It grows on logs as I understand it, hence has been placed in the 

 section Lentus. It is so much more obese and fleshy than the true Lentus that I 

 think it is better placed in Ovinus. 



POLYPORUS POPANOIDES. Pileus uniformly pale, isabelline 

 color. 17 Flesh rather soft. No distinct cuticle, but the surface seems 

 harder than the flesh. Stipe short, thick, excentric, inserted very near 

 one side. Pores minute, concolorous, about 5 mm. deep. Spores sub- 

 globose, 3/^2-4, hyaline, smooth. 



This is known from one collection at Kew made in Mauritius, but the col- 

 lector's name is not given. It is about ten inches in diameter, an inch thick and 

 has a short, thick stem near one side. 



POLYPORUS LUTEOLUTEUS. This was named by Professor McGinty 

 from the United States, and probably belongs to this section but is unknown 

 to me.
