SECTION PETALOIDES. 



Fig. 442 

 Petaloides megaloporus with the peculiar cystidia. (Drawing by Miss Wakefield). 



b. WITHOUT SETAE. 



COCHLEARIFORMIS. Plant black now but has probably 

 changed in drying. Spathulate with a long stipe. Context thin, of 

 peculiar, thick-walled hyphae cells such as have not been otherwise 

 noted by me. Pores small, dark now. Spores globose, 5 mic., white. 

 Only known from types at Kew, from Malay. 



TRISTICULUS. Color dark, almost black, thin, smooth. Pores 

 small. Stipe short, lateral. Known from but two specimens, one at 

 Paris and the other at Kew. 



(Cfr. also stereinus and holotephrus in Sect'on 22.) 



20. POLYPORUS. COLORED CONTEXT AND SPORES. 



(All of the preceding are supposed to have white spores.) 



I do not know that there are any species with colored context and spores 

 and lateral stems except in the section Ganodermus. The cotype specimen 

 Kew of Polyporus sideroides has these characters, but the type specimen at 

 Leiden has a thick, spongy, pleuropodal stipe and would be looked for in section 

 35 of Spongiosus.
