288 POLYPOEEAE OF SOUTH AFRICA. 



1. Lenzites trahea, Otth. 



Plants annual, sessile, pileus dimidiate to laterally expanded, 

 at times imbricate, 1 cm. to 10 cm. by 1 cm. to 3-5 cm. by 01 cm. 

 to 0-6 cm., coriaceous to corky; surface cinnamon brown to greyish- 

 brown, corky, glabrous, to subtomeutose, smooth to rugulose, zoned 

 or azonate, context cinnamon-brown to snuff-brown, fibrous, corky, 

 1 mm. to 4 mm. thick; hymenophore poroid to labyrinthiform, 

 rarely entirely lamellate; pores or lamellae 1 mm. to 4 mm. deep, 

 in poroid forms the pores are irregularly angular and in lamellate 

 the lamellae freely anastomose; mouths 2 to 3 to the mm., con- 

 colorous with surface, edges thin, entire; spores smooth hyaline, 

 ellipsoid, l\x to 8ju, by 4jll to 7/x diam. 



Distribution . — Common on stumps and logs of Pinus and 

 Populus in Western Cape Province by the writer. 



2. Lenzites repanda (Pers), Fries. 



Pileus substipitate, circular to flabelliform or reniform, fre- 

 quently large, 2 cm. to 32 cm. diam. by 01 cm. to 1 cm. thick, 

 tough, coriaceous to somewhat firm and rigid; surface azonate to 

 zoned, pure white when fresh, glabrous, smooth or tuberculate, 

 margin entire to undulate and rarely lobed ; context 1 mm. to 

 3 mm., white to cream coloured, floccose, fibrous, corky, zoned; 

 hymenophore poroid to daedaloid and lamellate, lamellae 0-5 mm. 

 apart, 1 mm. to 4 mm. deep, coriaceous firm, branched and anasto- 

 mosing, edges white to discoloured; spores hyaline, oblong or sub- 

 allantoid, 5/x to 8-5/x by 2/a to 3ja; hyphae hyaline, branched, 4ju, 

 to 5-6/x diam. 



Distribution. — Common on dead logs and stumps. Recorded 

 by W. Haygarth from the Ngoye Forest, Zululand; Miss A. V. 

 Duthie, from Knysna, Cape; J. D. Keet, Eastern Cape Forest 

 Conservancy; common on Acacia mollissima stumps and logs in 

 midlands of Natal by the writer; Howick, Natal, by Geo. Hobbs. 



Daedalia elegans, Spreng., Trametes elegans, Fr., are really 

 the same fungus and the older name, Lenzites applanata (Klotz) 

 ex Fries is also held to be synonymous; Lenzites Palisoti, Fr., is 

 usually also held to be synonymous, but I have not seen specimens 

 so referred. There are other synonyms for this common fungus. 



3. Lenzites betulina (Linn), Fr. 



Plants annual, sessile; pileus, dimidiate to flabelliform, imbri- 

 cate, coriaceous, to corky, 1-5 cm. to 9 cm. by 1 cm. to 6 cm. by 

 0-3 cm. to 1 cm. ; surface tomentose marked with concentric zones, 

 prevailing colour greyish, and in one collection a red zone was 

 present; faintly furrowed to plicate; context 0-4 mm. to 2 mm., 

 white, coriaceous, azonate; hymenophore lamellate, rarely poroid, 

 lamellae coriaceous, white to cream; edges entire, undulating; 

 spores hyaline, oblong, 4/x to 6/m by 2/x to 2-5/x; cystidia hyaline, 

 sharp-pointed. 



Distribution. — A widespread and common saprophyte on dead 

 logs and stumps. Recorded by J. D. Keet on dead Olea laurifolia
