 ■entire, reddish purple to blackish ; spores (teste Lloyd) hyaline, 

 .allantoic!, 4/i to 5/x by 1-5/ul ; hyphae 4/x. 



Distribution. — On dry Podocarpus sp. and Rhus Icevigata in 

 Eastern Cape Conservancy; W. Haygarth, Ngoye forest, Zululand; 

 Nottingham Road, Natal, by the writer. 



Recognisable by dark coloured gelatinous tubes separable from 

 the context. 



7. Polyporus conchoides, Mont. 



Pileus thin, sessile, imbricate, laterally connate, coriaceous, 6 

 cm. to 10 cm. by 5 cm. to 7 cm. by 0-5 cm. to 0-7 cm. ; surface 

 glabrous to hirsute, rough, pure white when fresh, becoming yellow- 

 ish ; context thin. 0-5 mm. to 0-6 mm. soft-fibrous ; tubes short, 0-5 

 mm. or less, white, drying flesh colour, gelatinous when fresh or 

 moistened and separable from context as an elastic layer ; mouths 

 ■sub-rotund to angular, 4 to 5 to the mm. ; edges thin, entire, white 

 become flesh colour; spores hyaline, allantoid, 4-5/x to 5/a by l/i to 

 1-8/x ; hyphae 3-6/x to 5 /a. 



Distribution. — W. Haygarth at the Ngoye Forest, Zululand, 

 •on logs. 



Distinguished from P. dichrous by different colour of pores. 



8. Poly/porus ochroleucus, Berk. 



Pileus sessile, applanate to ungulate, small, 1-4 cm. to 2 cm. 

 by 0-7 cm. to 1 cm. in a few specimens attached by a reduced base, 

 ^urface yellowish-ochre, dark coloured in old specimens, rough with 

 appressed fibres, or smooth, indistinctly zoned; context 3 mm., 

 hard, fibrous, pale yellowish, tubes 1 mm. to 4 mm. long, white 

 becoming yellowish; mouths circular 4 to the mm., edges entire, 

 thick, white, spores oblong, hyaline, truncate, 13/x to 15/x by 7-4/a : 

 hvphae 4/i. to 6/a diam. 



Distribution. — Found saprophytic on Trie hod ad us sp. and on 

 ■Curtisea faginea in Eastern Cape Forest Conservancy by J. D. 

 Keet and the writer. 



The hyaline, truncate, spores combined with the small size and 

 •colour of the pileus would serve to recognise this fungus. On the 

 under surface the pileus is often convex. 



D. Polyporus biformis, Klotz. 



Pileus sessile, effused reflexed, coriaceous, soft and pliable when 

 fresh, the reflexed portion dimidiate, applanate, imbricate, laterally 

 •confluent, 3-5 cm. to 6 cm. by 1-3 cm. to 3 cm. by 0-6 cm. to 1-3 cm. ; 

 surface white to yellowish-buff, rough with appressed fibrils or 

 rarely smooth; context soft corky, fibrous, white to yellowish, 

 ,1 mm. to 5 mm. thick; tubes 2 mm. to 5 mm. long, white when 

 fresh becoming discoloured; mouths irregular, circular to angular, 

 1 to 2 to the mm. ; edges thin, soon breaking up into teeth; spores 

 hyaline, oblong, curved, 6-4/x to 7/t by 2-7/x ; hyphae 3/x to 4/x diam.
