Fig. 485 

 Melanopus Guyanensis (with pores enlarged X6). 



RHIZOMORPHUS (Fig. 479). Produced by long, black, woody 

 rhizomes which I judge are aerial. Known from abundant material 

 in Montagne's herbarium from tropical America. 



VERNICOSUS. Mesopodal, black. Quite peculiar structure, 

 having the dark hyphae prolonged into protruding pointed setae in 

 the pores. Known from a single specimen at Kew from Brazil. 



VELUTICEPS (Fig. 480). Quite different from all others of 

 this section, the pileus having the general appearance and color of 

 Polystictus perennis. Stem black, spores doubtless white. Not re- 

 lated to perennis however. Known from one collection from Africa 

 at Kew. 



HEMICAPNODES (Fig. 484). Slender, smooth, sometimes in- 

 fundibuliform at first. The slender, black stipe is sometimes meso- 

 podal and lateral in the same collection. Originally from Ceylon, 

 common in Samoa and seems to occur in the East generally.
