KEY TO APHYLLOPHORALES 



THELEPHOKACEAE. 



1. Hymenium separated from the mycelium by an 

 intermediate layer of hyphae. 



Receptacle erect, much branched, branches] 



flattened in a lamellar, or plate-like manner, > Sparassis. 



fleshy. Hymenium smooth. Spores white 



Receptacle simple, or branched, stipitate, ses-\ 



sile, effuso-reflexed, rarely resupinate, cori-l 



aceous. Hymenium smooth. Flesh pale. Spores i 



white. Cystidia hyaline J 



Like Stereum, but cystidia, or setae coloured.] 

 Flesh coloured. Spores white, or coloured 



[Like Stereum, but hymenium smooth, granu-j 



lar, or faintly ribbed. Flesh coloured. Spores f [Phylacteria.] 



coloured, angular, echinulate, or verrucose] j 



Receptacle sessile, or produced behind into a-j 



stem-like base, coriaceous, or woody. Hy-l 



menium with fan-like folds, or radiating woody, [ 



branched ribs, or veins. Spores white J 



2. Hymenium seated directly on the mycelium. 

 Receptacle resupinate, waxy, or floccose. Hy-\ 

 menium smooth, with scattered protuberances 



caused by the breaking through of fasciculate, \- Epithek. 



Stereum 1 



Hymenochaete. 



Cladoderris. 



sterile, mycelial hyphae. Spores white. 

 tidia 



Cys-l

Receptacle saucer-shaped with a free margin, \ 



or resupinate and adnate, floccose, or crusta- 



ceous, becoming coriaceous. Hymenium 



smooth, pulverulent, with much granular, or Y Aleurodiscus. 



crystalline matter. Spores white, large ; basidia 



large, sterile basidia or paraphyses moniliform, 



or racemose 



Receptacle resupinate, waxy, crustaceous, or 



floccose. Hymenium waxy, smooth, or tuber- 



cular, continuous, often cracked. Spores white, L Corticium 2 . 



rarely faintly coloured, smooth. No cystidia; 



sterile basidia (cystidioles) sometimes emergent/ 



Like C&rtirium but the hyphae and hymenium] r> f - 



traversed by long, cystidia-like bodies, whose I . , 



walls are never thickened, nor incrusted withj L, U ^-j- \ 



crystalline deposits (gloeocystidia)
