STEREUM SPONGIAEPES (Fig. 533). Pileus infundibuli- 

 form, reddish brown, with a spongy, tomentose pad. Hymenium 

 even. Cystidia none. Spores globose, hyaline, smooth, 4 mic. 

 Stipe with a thick pad of spongy tomentum. 



This species is related to Stereum caperatum, but is much more 

 scantily known. The type (Australia) is in the British Museum. The 

 type is not so typically " spongiaepes " as our figure, but evidently 

 same species. No specimen is at Kew excepting a recent collection 

 from New Caledonia. The species was listed by Berkeley both as 

 Thelephora and Stereum, and is compiled under both genera in 

 Saccardo. It is rare in the museums of Europe, and the only speci- 

 mens I have seen are at London and a misnamed specimen from 

 Australia at Berlin. 



SYNONYMS, ETC. 



Cladoderris infundibuliformis is quite a different plant from Stereum caperatum, but many 

 specimens of the latter are labeled in the museums as being Cladoderris infundibuliformis. 



Stereum Golias, South America, Spegazzini. Cotype at Paris is typically Stereum caperatum 

 subsessile specimen. 



Stereum infundibuliforme, South America, Hooker (as Thelephora) (not Cladoderris infundi- 

 buliformis as often determined). Xo type exists. I found none at Kew and Berkeley states some- 

 where that he never saw one. From the short description it is almost surely the same plant as now 

 known as Stereum caperatum. Stereum infundibuliforme was compiled in Fries' Epicrisis, but seems 

 to have escaped Saccardo. 



SECTION 2. 



Stipitate, with a mesopodial stipe. Smooth, white or pale. I suspect that 

 some plants are included in Section 4 which are brown as found in the museums and 

 "white or pale" when growing.

 Stereum diaphanum. 



STEREUM DIAPHANUM (Fig. 534.) Pileus infundibuliform, 

 with thin margin. Smooth, pale or white. Stipe mesopodial, slender, 

 glabrous, or white with mycelial pubescence, rooting. Hymenium 

 even, white. Cystidia, none. 



This plant occurs very rarely in the United States, and there is 

 one collection known from Japan. It is quite different from our other
