POLYPOREAE OF SOUTH AFRICA. 263 



24. Polyporus luteus, Nees. 



Pileus stipitate, spathulate to flabelliform 1-8 cm. to 8-5 cm. 

 by 2 cm. to 5 cm. by 0-3 cm. to 0-7 cm., firm to more or less flexible; 

 surface glabrous, zoned, yellow to dark-brown; context 1 mm. to 

 3 mm. thick, white, fibrous, corky, firm; tubes 1 mm. to 2 mm. 

 long, white to yellowish within; mouths minute, circular, 5 to 6 

 to the mm. ; edges entire, white to yellowish, shining; stipe lateral 

 1 cm. long by 0-5 cm. to 1 cm. diam., disciform. 



Distribution. — Recorded by W. Haygarth from the Ngoye 

 Forest, Zululand. 



25. Polyporus sanguineus (Linn), Fries. 



Pileus coriaceous, sessile, or attached by a reduced base and 

 substipitate, varying dimidiate, flabelliform, reniform, conchate or 

 circular and depressed in the centre, often imbricate and laterally 

 connate, 2-5 cm. to 7 cm. by 6 cm to 10 cm. by 01 cm. to 0-8 cm. ; 

 surface bright red, fading in old specimens to pure white, tomen- 

 tose to glabrous, zoned or azonate ; context 0-9 mm. to 3 mm. 

 thick, soft and floccose, red to yellowish-red, zoned or azonate; 

 tubes 0-3 mm. to 1 mm. long, concolorous; mouths angular or cir- 

 cular 4 to 6 to the mm. ; edges entire, bright red, fading like sur- 

 face; spores hyaline, globose; hyphae 3-7/x to 6ja diam. 



Distribution. — A common saprophyte on dead logs and stumps 

 and observed growing on live Aloe sp. Distributed throughout 

 the Union. 



The plant is recognised by its red colour throughout. Another 

 species with similar colour is ]'. cinnabarinus Jacq. ex Fr., which 

 appears to differ from P. sanguineus primarily in being thicker 

 and never substipitate. 



The stipe varies from a mere attenuation to 2 cm. long. 



26. Polyporus cinnabarinus (Jacq.) Fr. 



Pileus annual, at times reviving, sessile to somewhat reflexed, 

 dimidiate to laterally extended, leathery, tough, becoming firm 

 and rigid, 3 cm. to 7-5 cm. by 2-5 cm. to 5 cm. by 0-5 cm. to 1-5 

 cm. ; surface azonate to indistinctly zoned, orange to cinnabar-red, 

 paling in old specimens like P. sanguineus, velvety, tomentose to 

 glabrous; context zoned, soft corky, fibrous, red to yellowish red, 

 0-4 cm. to 1-3 cm.; tubes 0-5 mm. to 1 mm. long, concolorous; 

 mouths 3 to 5 to the mm. subrotund to angular; edges entire, 

 cinnabar red. 



Distribution. — Found around Durban and in Eastern Cape 

 Forest Conservancy, by the writer. 



This fungus is similar to Polyporus sanguineus and differs only 

 in being thicker and having its context more strongly zoned. 

 Several collections of P. sanguineus had specimens intergrading 

 into this. 



27. Polyporus occidentalism Klotzsch. 



Pileus sessile, or effused reflexed, coriaceous to firm and rigid, 

 dimidiate, applanate, frequently imbricate, 6 cm. to 13 cm. by
