P0LYP0REAE OF SOUTH AFRICA. 283 



Distribution. — A common plant on dead logs and stumps. 

 Found at Pretoria, Transvaal, on fence posts by the writer; at 

 Umfolosi, Zululand, by the writer; at Klapmuts, Cape Province, 

 on stumps of Popuhrs sp. and Finn? sp. by the writer; in the 

 Ngoye Forest, Zululand, by W. Haygarth. 



7. Trametes violacea, Lloyd. 



Plants annual, sessile, pileus dimidiate, applanate, imbricate, 

 connate, firm and brittle when dry, decurrent, 2-5 cm. to 5-5 cm. 

 by 1-5 cm. to 5-5 cm. by 0-2 cm. to 0-5 cm. ; surface corky, firm, 

 purple, zoned, 2 mm. to 3 mm. thick; margin entire; tubes 

 0-5 mm. to 1-5 mm. long, firm, concolorous with context; mouths 

 circular to angular, 5 to 6 to the mm., edges entire, thin, purple; 

 hyphae 3jx to 6/x. 



Distribution. — Saprophytic on logs. Mr. C. G. Lloyd named 

 the plant from specimens collected in Natal by A. T. Janse, and 

 the plant has also been observed around Pietermaritzburg, Natal, 

 by the writer. The plant is close to Polyporus vinosus, Berk., but 

 lighter in colour and more brittle. 



8. Trametes griseo-lilacina, n. sp. 



Plants annual, sessile; pileus coriaceous to corky, applanate, 

 imbricate, dimidiate to laterally extended, 3 cm. to 10 cm. by 

 2-5 cm. to 4 cm. by 4 cm. to 0-8 cm. ; surface concentrically sulcate, 

 tomentose to glabrous, fasciculate setose, rugulose, scrupose, grey 

 to greyish fawn, margin acute, tomentose on upper surface; con- 

 text corky, firm, fibrous, lilac-mauve to mouse coloured, 3 mm. 

 to 4 mm.; tubes 0-5 mm. to 2-5 mm. longf, lighter than context; 

 mouths unequal, irregular, round to elongated and angular, 2 to 3 

 to the mm.; edges thick, entire, concolorous, lilac-mauve; spores 

 hyaline, smooth, oblong, 3-7/x by 7-5/x ; hyphae simple, 3-5/a to 6/a. 



Distribution. — Single collection by Geo. Hobbs on railway 

 sleeper at Illovo River, Natal. (Tvpe in Natal Herbarium, 

 No. 921.) 



The context colour and colour of pore mouths is peculiar and 

 should aid in the identification of the fungus. The fungus is 

 evidently related to the Australian Trametes lilacino-gilva (Berk), 

 Lloyd, but with rougher surface and irregular pore mouths. 



9. Trametes keetii, n. sp. 



Plants sessile; pileus dimidiate, applanate, woody, firm and 

 rigid, slightly decurrent, 3 cm. to 6 cm. by 2 cm. to 3-5 cm. by 

 0-4 cm. to 1-5 cm. ; surface grey to purplish black, finely tomentose, 

 smooth to scrupose; margin acute to rounded, grey; context 0-2 cm. 

 to 1 cm., hard, rusty brown; tubes firm, 0-2 mm. to 4 mm. con- 

 colorous with context; mouths minute, subrotund, 6 to 9 to the 

 mm.; edges entire, thick, firm, concolorous; spores not found, taken 

 to be hyaline, setae present, slender, subulate 21p, to 28/a long; 

 hyphae 4/a to 6/a diam.
