266 POLYPOREAE OF SOUTH AFRICA. 



when fresh becoming more firm and rigid on drying, 7 cm. to 

 20 cm. by 4 cm. to 16 cm. by 0-5 cm. to 3 cm.; surface finely 

 tomentose to glabrous, fleshy white to lemon or orange yellow ; 

 margin undulate to lobed; context white to yellow, of a cheesy 

 consistency and friable when dry, 0-3 cm. to 2-7 cm. thick; tubes 



1 mm. to 4 mm. long, readily produced on any part of the fungus 

 according to situation and position; mouths angular to somewhat 

 irregular, 2 to 4 to the mm.; edges entire, yellow or white; spores 

 hyaline, subglobose to oval; hyphae 7/x to 19/x, diam. 



Distribution. — Observed not uncommonly as a wound parasite 

 on trunks of Quercus in the Stellenbosch district and around Cape 

 Town by the writer and in the same localities on Eucalyptus stumps 

 and in fire wounds on live Eucalyptus trees; collected at Knysna 

 by J. D. Keet. 



The plant is recognisable by the densely imbricated pilei ; 

 fleshy nature when fresh, soft cheesy and friable consistency of 

 context and the ease with which pores develop on almost any part. 

 The writer has frequently seen the plant growing without showing 

 any trace of yellow, but the other characters are sufficiently dis- 

 tinct to aid in recognition. Fetch records from Ceylon this fungus 

 to be brick-red in colour, and this has also been observed in some 

 South African specimens, though it appears to be uncommon here. 



34. Polyporus anebus, Berk. 



Pileus sessile, imbricate, dimidiate, decurrent behind, at times 

 somewhat attenuated at attachment, 2 cm. to 5-5 cm. by 



2 cm. to 3-5 cm. by 0-2 cm. by 0-5 cm., firm and rigid; surface 

 hard, dark fawn, indistinctly zoned, minutely pubescent, undulat- 

 ing and smooth to rugulose; context fibrous and corky, pale yellow 

 to yellow brown; 1 mm. to 2 mm.; tubes 1 mm. to 3 mm.; mouths 

 cinnamon coloured, subrotund 5 to 6 to the mm. ; edges entire, 

 cinnamon coloured; spores globose, hyaline, smooth, 3-7/x diam.; 

 hyphae 4/j, to 7j± ; setae none. 



Distribution. — Found by W. Haygarth in the Ngoye Forest, 

 Zululand. 



35. Polyporus nigrolucidus, Lloyd. 



Plants terrestrial annual, stalked; pileus circular, depressed 

 in centre, rarely reniform, 4 cm. to 9 cm. diam. by 5 cm., surface 

 black, laccate, rugulose; context whitish to brown, 1 mm. to 3 mm. 

 thick, soft; tubes 1 mm. to 3 mm. long, white within; mouths 

 subrotund to angular 5 to 6 to the mm.; edges thin, entire, white, 

 becoming discoloured; spores coloured, apiculate, truncate, 4fA to 

 5-5/x by 6/tx to 7-5ju, ; hyphae 5-5/x to 7-5/a; stalk central, rarely some- 

 what excentric or lateral, or deeply rooted, 12 cm. to 20 cm. long 

 by 5 mm. to 7 mm. diam., interior soft. 



Distribution. — Found at Durban, Natal, by J. M. Wood, and 

 collected here also by the writer. 



Distinguished bv black laccate surface of pileus and stalk.
