ADDITIONAL NOTES ON POLYPOROID ISSUE No. 2. 



It seems that we were a little late in prophesying that the fleshy section of 

 Hexagona would some day be discovered to be a "new genus." It develops that 

 this has already been done. 



Also we learn that Polyporus Rhipidium (Fig. 357) is a genus of Aga- 

 rices. That may explain why it was not included in North American Flora. 

 The author may have taken it for an agaric. It 

 looks to me about as much like an agaric as does 

 Daedalea quercina, which we were at one time in- 

 formed was the "nomenclatural type of the genus 

 Agaricus" (sic). 



We have learned a little additional history of 

 Polyporus Rhipidium at Paris. It develops that Le- 

 veille's type of "Gloeoporus pusillus" is the same 

 plant. It is a miserable little remnant that has never 

 been recognized since Leveille "described" it sixty 

 years ago. I have seen it often, and while well 



acquainted with Polyporus Rhipidium I have never 



Pig 357 recognized it, and probably never would if I had 



(Enlarged 6 x ) n t traced its connection to Persoon's specimens at 



Leiden (cfr. p. 24). I have not looked up the 



"dates," but it may prove of interest to the date experts. Nothing seems to 

 give them so much pleasure as to change a name such as Polyporus Rhipidium 

 that has been universally used for many years, and I hope this discovery may 

 prove of service to them. 



I present here a figure (358) of the stalked form of Polyporus volvatus, 

 called "var. Torreyi." It was the first collection known and the figure is made 



from a specimen in Fries' herbarium. As 

 I have previously stated I consider it prob- 

 ably an abnormal development of a "stipe." 

 As will be noted the "volva" has been 

 broken away from this specimen. 



Additional synonyms" have developed 

 for Polystictus pinsitus. Polyporus tener 

 and Polyporus gibberulosus, as named by 



Fi 358 Leveille, are both in my opinion this plant. 



I have seen in the collection of Professor 



Patouillard a specimen which Ellis sent him as Hexagona vittata. It is Poly- 

 stictus pinsitus. We use the name Polystictus pinsitus in its usual sense, 

 a very common species in the tropics, with dark pores. It was originally named, 

 by Swartz from Jamaica, Polystictus villosus, but the Friesian name is gener; 

 applied to it. Still Fries states that Polystictus pinsitus has white pores and 

 develops that there is a form in Brazil (whence the plant was named) with whi 

 pores. It may be better to restrict the name Polystictus pmsit 

 pored form.
