Mr. C. (i. Klovd, and thi> sprcinuni i> tliickcr than rolyporus 

 Jncidiis as usually found in South Africa, and the siu-face more 

 resinous. I have several s])eeiniens oi Polyf^onis rrsiiiosKS 

 Schrad.. also named for nie hy Mr. C. G. Lloyd, and thc>o he 

 regards as hul sessile forms of P. liicidiis. The surface is 

 decidedly resinous. Polyporns Ciirtisii Berk, is close to P. 

 Incldus. the only difference heinj.;- that in tlie former the surface 

 is more yellowish or almost white. 



As stated hy Lloyd,* the following description will ai)i)ly 

 to all the annual Caiwdcnniis Polyporus forms: " l^ileus sessile. 

 applanate, with a thin, reddish-l)ro\\n. nuM-e or less laccate sur- 

 face. Context dark burnt uml)er, \aryin^ light. Lores small, 

 round, from 1 to I'S cms. Vnv^, with white or yell<AV mouths. 

 Spores obovate, truncate at base, (> — 10 to 8 — ■ 10 X i- — 14 y^, 

 smooth, varying- to strongly ])unctate. There have been numerous 

 new specimens named, to all of which the above description will 

 apply. The only thing that can be done is to ado})t names for 

 the most extreme forms, and then refer the specimens to the 

 nearest one. The spores even in the same specimens vary from 

 smooth to strongly punctate, but tiie latter are said to be rough." 



It is evident that Polyporus lucidus is not necessarily stalked, 

 and we must regard the ifcllowing as close to it, and some cer- 

 tainly svnonvnious : — 



Polyporus rcsiiiosus Schrader. 



Polyporus rcsiiiaccus Boudier. 



Polyporus fulvcllus Bresadola. 



Polyporus scssilis Murrill { (ianodcruia sessile). 



Polyporus Curtisii Berk. 



In Saccardot this fungus figures as Foiues lucidus ; l)ut I only 

 know it as an annual, and have thus far not come across a speci- 

 men with the pores in strata, as is tyiiical of Pomes. 



Later we hope to deal more fully with the fungi related to 

 P. lucidus; in the meantime an\- s])ecimens will be of material 

 assistance. 



Hosts ox wiiicti roLvroRis lucidus has b?:e\ okskiu'ed. 



Polyporus lucidus has been recorded on the following 

 hosts : — 



Acacia, sp. ; on roots and stem of live Salix (willow) ; base 

 of dry Pticroxylon utile ( sneezewood ) base of dead ZLzyphus 

 mucronata ( wacht-een-beetje) ; live Olea verrucosa (wild olive). 

 In addition I have a numl)er of s])ecimens from undetermined 

 hosts. Polyporus rcsiiiosus is common on dead stumps in and 

 around Durban, where I have twice found Polyporus Curtisii on 

 dead logs. 



An interesting occurrence of this fungus was brought to 

 my notice by Mrs. J. E. Farrar. of Dur]:)an, in whose house it 

 was breaking through a concrete floor in three ])laces close to-
