but they are all correct and none are "50 cm." in diameter. Leveille's 

 .description would point to Polystictus Persoonii though "pores minu- 

 tissimus" hardly agrees. 



plicatus (Blume Mss.). Type not found. 



perpusillus (Pers. Mss.). I saw this collection on a previous trip 

 to Leiden but did not look it up this time. It is in Persoon's herbarium. 

 It is a little Fomes but there is nothing to indicate that it came from 

 "America boreali" as Leveille states, and to my knowledge it is not an 

 American species. 



pulchella (Boletus apus Kuhl.) as Hexagona. Type not found 

 at Leiden. There is a specimen labeled by Leveille in Patouillard's 

 herbarium (Cfr. Hex. synopsis, p. 25) but it does not agree with 

 his description which was "zonis castaneis." In the original sense it 

 seems to be a common species in the East and in Africa, marked with 

 a dark red stain, and is called in my pamphlet Hexagona discopoda, 

 and is probably the same as tricolor of Fries. 



pusillus (Pers. Mss.). Type in Persoon's herbarium. It is the 

 frequent little species of the tropics, well known under Berkeley's name 

 Polyporus Rhipidium. (Cfr. Pol. Issue p. 33.) 



rhodophaeus (Rosa mala, Jungh.) Type in Box 171 has been re- 

 cently referred to semilaccatus of Berkeley. 



rigidus (Pol. No. 100). Type, not found. 



rugulosus (monochrous, Mont.? Pol. No. 57). Type not found 

 by me though I think it must be in some box as there is an index sheet 

 in the covers. This name has been lately taken as referring to the same 

 plant as Polyporus zonalis of Berkeley. 



sideroides (Pol. No. 24 & 101, KortlO Type No. 24 is in Box 95. 

 It is the most noteworthy species that Leveille named. In general 

 appearance it reminds me of Polyporus Schweinitzii. It has a pleuro- 

 podal, thick, spongy, tomentose stipe. The context is ferruginous and 

 the abundant spores are colored, globose, 8-9 mic. Polyporus Kor- 

 thalsii in the original sense of Leveille is probably a sessile form of 

 the same species. The only specimen I had previously seen of Poly- 

 porus sideroides is at Kew, named by Leveille, and this has a short, 

 lateral stipe. The best specimen of this species at Leiden is in Box 237. 



splendens (sericeus v. nitidus). Type in Box 132.* It is the 

 common Polystictus pergamenus. 



splendens (Herb. Miq.) as Daedalea. Type not found and prob- 

 ably could not be identified if it were. 



tener (Sumatra, Korthals) as Favolus. Type not found. 



tenuissimus (Pol. No. 4). Type not found. 



trachodes (tuberculosus, Jungh.) Type in Box 34. It is now 

 labeled correctly, Polyporus scruposus which is a form of Polyporus 

 gilvus. 



vittata (Korthals) Trametes. Type not found.
