102 Murrill: Polyporaceae ok North America 



Brazil. The pileus is said to be nine inches broad, five inches long - 

 and as thin as paper, resembling most a species gathered by Schom- 

 burgk in Brazil communicated by Berkeley to Montague under 

 the name of Hexagona varicgata, but considered by him only a 

 non-setose state of his Hexagona aculeata. 



A specimen in the herbarium of the Agricultural Department 

 at Washington, collected by Wright in Nicaragua and labeled 

 Hexagona papyracea Berk., differs from plants ordinarily called 

 Hexagona varicgata in its thinner, flexible pileus and smaller, stag- 

 colored pores. There is such a specimen also in the herbarium of 

 the New York Botanical Garden collected in the Peruvian Andes 

 by Pearce and marked Hexagona varicgata Berk. Both of these 

 specimens, however, are only var. membranacea of Hexagona 

 varicgata, as type plants at Kew show. 



Hexagona cingnlata Lev. Ann. Sci. Nat. III. Bot. 2: 200. 

 1844. Described from material collected in Hispaniola as follows : 



" Pileo coriaceo reniformi membranaceo nudo zonato pallide 

 cinereo nitente, alveolis mediis fuscis e rotundo hexagonis intus 

 cinereis." 



" Petite espece reniforme, nue, zonee, de couleur pale cendree, 

 et brillante, large de 2 a 4 centimetres ; ses alveoles sont parfaite- 

 ment regulieres, de moyenne grandeur, fauves, obtuses a la marge, 

 et cendrees a l'interieur." 



From the above description this species can hardly be different 

 from Favolus tennis (Hook.). 



Hexagona leprosa Fr. Nov. Symb. 101. 185 1. Described as 



follows : 



" Pileo suberoso crasso. pulvinato laevigato leproso-pruinoso 

 umbrino, alveolis profundis amplis acutis fusco-umbrinis, intus 

 nudis." 



" In Insula San Jan, Indiae occidentalis. Oersted." 



Plants of this name at Kew are very distinct from other North 



American species, being much thicker and having much longer 



tubes, reminding one somewhat of a wasp's nest. Further study 



is necessary before their exact relations are known. 



Hexagona unicolor Fr. Nov. Symb. 10 1. 185 1. Described 



from " America calidiori " as follows : 



" H. unicolor, dilute ferruginea, pileo coriaceo rigido subflexili 

 applanato concentrice sulcato glabro, alveolis mediis vadosis 

 angulatis."
