396 THELEPHORACEjE 



FAM. IV. THELEPHORACE.E 



Erect and stipitate, cup-shaped, effused, with the upper portion 

 free and reflexed or resupinate. Hymenium inferior or amphigenous, 

 coriaceous, waxy or gelatinous, even to rugulose, ribbed or papillose, 

 the surface glabrous, finely pulverulent or minutely velvety, with 

 projecting setae. Basidia clavate, i-4-spored, normally tetrasporous. 

 Spores usually aseptate, 3-septate in the non-British Hcterobasidhtm 

 chlorascens. The papillae are for the most part accidental, generally 

 arising in the resupinate species from Sp/ueriee, growing on the bark 

 beneath and not existing when the fungus grows on a surface free 

 from Sphceria. True papillae, however, sometimes occur on the 

 pileate, terrestrial species. Some species are occasionally phosphor- 

 escent, as 1861. In the gelatinous species the aseptate and tetras- 

 porous basidia distinguish them from certain members of Tremdlinacece, 

 where the basidia are longitudinally and cruciately septate, or if the 

 spores are aseptate the basidia are deeply bifurcate and bisporous. 

 Hypomyces rosellns often stains the hymenium of T/ielephora, Corficiitm, 

 and other genera of Thelephoraccce a bright purple-rose colour. 



Massee has published a Monograph of the Thelephoracetz in 



Jonrn. Linn. Soc. (Bot.) xxv. (1889) and xxvii. (1890). The sequence 



of the genera adopted here is that of P. A. Saccardo, Sylloge Fnngornm, 



vol. vi., which is a slight modification of the order as given in Fries's 



Hymenomycetes Enropai. Species 1781 1925
