dimidiate, thick, rigid. Surface hirsute, strigose (denuded in Fig. 

 1068). Context brown. Teeth mouse grey, irregular, tubercular, 

 somewhat daedaloid. Basidia hyaline, forming a palisade layer. 

 Cystidia similar to basidia, but longer, hyaline, thick walled, smooth. 

 Spores 4x8, hyaline. The subhymenial hyphae are deeply colored.

The general position of the plant is doubtful. It is perhaps a 

 better Radulum and it might be called Daedalea. While I would 

 not suggest that it is a variant of Polystictus versatilis, I am satisfied 

 that there is some relation between the two plants that I can not 

 explain. 



FOMES SETULOSUS, FROM MISS MARGARET L. FLOCK- 

 TON, COLLECTED BY MR. BLAKELEY, AUSTRALIA. (Com- 

 pare Synopsis Fomes, page 243.) The 

 presence or absence of setae on the 

 hymenium is usually considered of 

 specific importance in the Fomes with 

 brown context. Indeed in our Synopsis 

 of the genus, we grouped the species 

 on this character. Species that have 

 setae like Fomes conchatus, Fomes 

 torulosus, Fomes Everhartii, Fomes 

 senex, etc., seem to always have them. 

 Others, like Fomes ribis, Fomes fomen- 

 tarius, never have setae. 



But we are convinced that Fomes robustus of Europe and the 

 United States is the same species as Fomes setulosus of Ceylon and 

 Australia, although with us the species never has setae to my knowl- 

 edge. From Australia we get collections sometimes without setae, 

 sometimes with a few setae, and sometimes with abundant setae 

 (Fig. 1069) as in the specimen just received from Miss Flockton. 

 In every other feature the plants are the same, and we believe are in 

 reality the same species.
