34 Murrill: Polyporaceae of North America 



low, or vernal, form which Retz described, while Schrader was 

 dealing with the darker autumnal form of the plant. In his synop- 

 sis, Persoon separates the two forms as varieties vermis and fas- 

 ciculatus. P. hiriihts of Berkeley and Curtis is to be referred to 

 the latter variety. 



This species is found on various kinds of decaying wood in 

 forests and groves, usually upon branches lying on the ground. 

 Its persistence far into the winter in the fresh state led Persoon to 

 give it the name by which it is generally known. Among the 

 specimens examined are the following : Tyrol, Bresadola ; Ber- 

 lin, Sydoiv ; Finland, Karstcn ; Sweden, Murrill ; Canada, Dear- 

 ness, Macoim ; Maine, Richer; New Hampshire, Miss Minns; 

 Connecticut, Wright; New York, Shear, Underwood, Overacker ; 

 Delaware, Commons ; Ohio, Morgan; Wisconsin, Lapham, Sey- 

 mour; Iowa, Hokvay ; Montana, Anderson. 



7. PoLYPORUS Tuba B. & C. Jour. Linn. Soc. Bot. 10 : 



305. 1868 

 This species is founded upon a single collectiqj^ by Wright in 

 Cuba, the types being at Kew. It is readily recognized by its 

 peculiar goblet-shaped form, resembling a long-stemmed PerAza 

 or a young stage of Cantharelliis cibariiis. Its substance is rela- 

 tively quite thick, the depression at the center being shallow in- 

 stead of deep as might be expected from its shape. The margin, 

 if not straight, is rolled inward instead of outward, and the stipe is 

 long, slender and undulate. 



8. PoLYPORUS craterellus B. & C. Jour. Linn. Soc. Bot. 



10 : 305. 1868 

 The type collection of this species was made by Wright in 

 Cuba. The name is well chosen and refers to a character by which 

 the plant is easily distinguished from its near allies. Plants col- 

 lected in Louisiana by Langlois are even more deeply infundibuli- 

 form than the types and are also somewhat larger. The species 

 occurs on decaying wood and appears usually in small clusters. 



9. PoLYPORUS Acicula B. & C. Jour. Linn. Soc. Bot. 10 : 



304. 1868 

 This minute species is represented by a single specimen, two 

 millimeters in diameter, collected on decayed wood in Cuba.
