Murkill: Polvporaceae of North America 101 



Peck's species, described from plants collected by J. J. Brown 

 on the Roata-n Islands off the coast of Honduras, is well repre- 

 sented, by a number of specimens collected recently in Honduras 

 by Wilson, and I do not find it distinct in its mature stages from 

 Hooker's plant. The fresh young sporophores have a strong 

 resemblance, as Peck says, to forms of Agaricus confragosus. 



This species is fairly common and, in some localities, rather 

 abundant in tropical America. Among the plants examined the 

 following may be mentioned : Guayaquil, Lagerheim ; Colombia, 

 Baker ; Nicaragua, C. L. Smith, Shimek ; Honduras, Wilson 4, 

 410, 770; Mexico, C. L.Smith; Cuba, Wright 315, Wilson. 



2. Favolus variegatus (Berk.) 

 Hexagona variegata Berk. Ann. Mag. Nat. Hist. II. 9: 196. 



1852. Proc. Amer. Acad. Arts & Sci. 4 : 122. 1858. 



This species was first described from plants collected in San 

 Domingo, as follows : 



" Pileo tenui coriaceo dimidiato rugoso crebri-zonato multi- 

 colori velutino ; hymenio umbrino poris mediis." 



It is a very showy plant and rarely escapes the collector, being 

 large and much expanded, with surface brilliantly marked with 

 variegated zones of red and brown tints. The typical form occurs 

 in southern Florida and the West Indies in fair quantity, while it 

 ranges either in this form or in one with smaller pores, called var. 

 membranacea at Kew, to various parts of Central America and 

 into South America. The well-known tendency of species in this 

 genus to vary in pore measurement prevents me from founding a 

 species on the variety just mentioned. Possibly when more is 

 known of the plants in the field, such a separation may be found 

 desirable. 



Specimens are at hand from Florida, Calkins, Small & Nash, 

 Small & Carter ; Costa Rica, Entires ; Nicaragua, Wright, C. L. 

 Smith; Mexico, Egcling ; Colombia, Baker; Brazil, Glasiou, 

 Balanza ; Peru, Pearce ; Bolivia, Bang.
