292 POLYPOREAE OF SOUTH AFRICA. 



to discoloured, soft, tough; tubes 2 mm. to 3 mm. long, decurrent 

 on stipe; mouths angular, radially elongated, 1 mm. to 2 mm. by 

 0-5 mm. ; edges thin, ultimately becoming split into irregular 

 teeth; spores (teste Bresadola) hyaline, oblong, 9/a to 12^ by 4/x to 

 5/a; setae present, coloured, aculeate and with aculeate spines. 



Distribution. — Found at Durban on log, by the writer. Easily 

 recognised by the coloured, spiny setae in the hymenium. 



In addition to the species named, Favolus dermoporus (Pers), 

 Lloyd, Favolus euro'paeus, Fr., and Favolus spathulatus (Jungh), 

 Bres., have been collected by the writer, but the material of these 

 has been very scanty. Medley Wood has further recorded Favolus 

 rhipidium, Berk., from Natal. 



2. Favolus brasiliensis, Fries. 



Pileus stalked, thin, applanate, coriaceous, spathulate, flabelli- 

 form or reniform, 2 cm. to 7 cm. by 1-5 cm. to 5 cm. by 01 cm. 

 to 0-4 cm. ; surface white, radially striate, minutely pubescent to 

 glabrous; margin thin, undulate to lobed and fissured with age; 

 context thin, up to 1 mm. white, soft; tubes 1 mm. to 3 mm. long, 

 decurrent on stalk, mouths 4 to 6-angled, elongated radially, 2 mm. 

 to 5 mm. by 0-8 mm. to 1 mm.; edges white changing to yellowish, 

 thin, splitting into irregular teeth ; spores hyaline, smooth; setae 

 absent; hyphae 2/x to 4jx; stalk lateral 0-5 cm. to 2-5 cm. long by 

 3 mm. to 5 mm. diam; somewhat dilated at attachment, finely 

 tomentose. 



Distribution. — Found around Durban by the writer, common 

 on dead logs. 



Favolus jacobaeus, Sacc. (Polyporus favoloides, Henn) is close 

 to above and differs in somewhat smaller pores. It is probably 

 best held as a small-pored form of it. In some collections of this 

 small pored form the surface was somewhat tessellate, and these 

 tended to connect this species with Favolus tessel/atus, Mont. 

 Favolus freisii, Berk and Curt., is a thin white species, but specimen? 

 so far seen of it have been very scanty. It, however, appears to 

 be too close to above. Specimens preserved by J. Medley Wood 

 (No. 99) under the name F. vibecinus, Fr., are evidently also 

 referable to the small pored form. 



Laschia, Mont. 



Small annual gelatinous pore-fungi, centrally or laterally 

 stipitate or sessile. Surface most frequently tessellate. Majority 

 coloured (a few white). Colour contained either in ordinary cuti- 

 cular cells, in stalked gland-like bodies, or in long cylindrical colour 

 cells.* In addition, some have hyaline cristated cells which may be 

 either oval and crowned with spiny processes or of the nature of 

 long cylindrical cells covered with spiny processes. Pores angular, 

 honeycombed, usually shallow. Spores hyaline. 



* This appears to have been first investigated by Mr. C. G. Lloyd.
