to me. All specimens known of Stereum cristatum (cfr. in Section 9) 

 have a somewhat similar growth. Hennings discovered that Stereum 

 hydrophorum was a "new species" of Hymenochaete (sic). The 

 discovery is chiefly noteworthy from the fact that it was neither a 

 "new species" nor a "Hymenochaete." 



STEREUM HOLLANDII (Fig. 549). Pileus infundibuliform 

 with a very short stem. Inner surface uniform, brown, pubescent 

 with narrow, raised, concentric zones. Hymenium smooth, yellowish 

 brown. Cystidia, none. 



Fig 549 



Stereum Hollandii. 



This is known from a single specimen (and figure) at Kew, found 

 in the cyathiforme cover and collected in Old Calabar, Africa, by 

 J. H. Holland. It approximates to some extent Stereum hydrophorum 

 of the American tropics, but the hymenium is glabrous and the 

 hyphse tissues are pale. 



Stereum cristatum will be found in Section 9 as the type specimens are petaloid. Some of the 

 cotype specimens at the British Museum are eccentric, with a tendency toward infundibuliform. I 

 presume the plant when perfectly formed is infundibuliform and belongs in this section. But one 

 collection known (Ravenel) from Southern United States. 



Stereum obliquum. Most of Zollinger's collections. No. 983, are petaloid, as shown in our figure 

 in Section 9. A few I have seen (at British Museum) like cristatum show a tendency toward infundi- 

 buliform and might be sought in this section. I believe Stereum obliquum to be same species as Stereum 

 affine, but a more slender form. Stereum affine also rarely takes infundibuliform shape. 



SYNONYMS. 



Hymenochaete (sic) crateriformis, Brazil, Hennings = Stereum hydrophorum. 



Stereum cyathiforme. South America, Fries. This is more a tradition than anything else. I do 

 not suppose any type exists, and Plunder's old crude figure which Fries cites does not represent any- 

 .hmg that grows nowadays. The probabilities are that cyathiforme was hydrophorum or caperatum, 

 though the crude figure Fries cites has no resemblance to either. Berkeley referred three collections to 

 Stereum cyathiforme, all of which are caperatum with short stipe and subeven hymenium (viz.: 

 Stereum hylocrater).
