Polyporus Madagascarensis. 



NOTE 106. Flesh ochraceous, thick, spongy, in some specimens ij cm. thick. 

 Hymenium umber brown. In all other respects it is same as Polyporus dichrous, of which 

 it is only a variety. 



Section with dark purple context. 

 Polyporus vinosus. 

 Polyporus durus. 



Section with brown context. 

 Polyporus gilvus. 

 Polyporus minuto fruticum. 



NOTE 107. Pileus very small, orbicular, i /2 to 1 cm. in diameter, ferruginous 

 brown. Context soft, spongy, concolorous. Pores darker, minute, the mouths round or 

 elongated irregular. Spores hyaline, globose, 4-4 Va mic., smooth. 



This little species is attached to twigs in the same manner as Polyporus fruticum. 

 It has the same color, and might be held as a small form, but we think it is distinct. 

 The spores are larger and the discrepancy in size of the plants is too marked to be classed 

 together. 



Section isabelline context. 

 Polyporus bicolor. 

 Polyporus pruinatus. 



Two collections, one thinner than the other. 



Polyporus anebus. 



(cfr. Letter No. 47.) Very close to pruinatus, but with smooth pileus. 



Section colored context and spores. 



Polyporus hispidus? 



The pores are not developed. We find no spores, and the surface is not so 

 "hispid" as it should be.
