34 MurrRILL: 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 vernus and fas- 
ciculatus. P. luridus of Berkeley and Curtis is to be referred q 
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; Bet- 
lin, Sydow ,; Finland, Karstex; Sweden, MWurrill ; Canada, Dear- 
ness, Macoun,; Maine, Ricker; New Hampshire, Mess Minus; 
Connecticut, Wright ; New York, Shear, Underwood, Overackers 
Delaware, Commons ; Ohio, Morgan ; Wisconsin, Lapham, 59 
mour ; towa, Holway ; Montana, Anderson.

This species is founded upon a single collection by Wright in 
Cuba, the types being at Kew. It is readily recognized by its 
peculiar goblet-shaped form, resembling a long-stemmed Pesisa 
or a young stage of Cantharellus cibarius. Its substance is rela- 
tively quite thick, the depression at the center being shallow in- a 
stead of deep as might be expected from its shape. The margitl, 
if not straight, is rolled inward instead of outward, and the stipe 1s 
long, slender and undulate.

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.

This minute species is represented by a single specimen, two 
millimeters in diameter, collected on decayed wood in Cuba.
