ILLUSTRATIONS. Persoon Icon, et Desc. t. 1, tig. 3. I am satisfied that this figure is mis- 

 leading as to the usual plant, at least both as to the regular infundibuliform shape and the setulose 

 hymenium as shown. Neither of these characters are borne out by the specimens still in Persoon's 

 herbarium, nor by the usual plant as found in recent years. 



I have a collection from France recently that seems to bear out Persoon's figure, and it is possible 

 that the usual merismatoid plant of the museums (and of Persoon's herbarium) is not the same as the 



ilem for tl 



infundibuliform plant originally. It is a proble 



the future. 



STEREUM ACULEATUM. Known from but one collection in Southern 

 United States, is piobably only the American expression of Stereum pallidum. 

 While on comparison it appears more regular, thinner, with thin, eroded edges, yet 

 it has same habits, fibrillose surface, color (darker, it seems), and is in the main the 

 same plant. It is apparently extremely rare. But two specimens were ever col- 

 lected by Ravenel one is at Kew, the other in the British Museum. 



STEREUM CONFUSUM. Known from but one collection from New Zea- 

 land, is likewise probably only a form of Stereum pallidum. It has the same color 

 and general characters, but the few specimens known are more simple and not 

 surely merismatoid in habits. 



STEREUM PETALODES (Fig. 551). Pileus reddish brown, 

 sessile, cut into lacerate lobes which appear merismatoid. As to 

 surface and color, very much like the preceding. It is known from a 

 single specimen from San Domingo. At first sight it appears as 

 though consisting of separate, spathulate individuals, but is really 

 one lacerated plant. It is therefore not "petaloid." Ule's distiibu- 

 tion 2756 from Brazil of Henning's deteimination has not the most 

 remote resemblance to it (cfr. Stereum crenatum).
