248 OvERHOLTS: DIAGNOSES OF AMERICAN Portas—Il 
and Louisiana. Issued in N. Am. Fung. No. 313 as P. obliquus 
from which it is quite distinct. 
Redescription: Perennial or at least persisting for three or 
four years, effused for 6-30 cm. in narrow elon ngate — patches! ea 
small shr ubs 0 or branches and 1~3.5 cm. broad, inseparable, 
(honey yellow to clay color) sterile border rarely more than 1 
mm. broad; subiculum extremely thin, cai alah: brown; 
tubes usually oblique, 1-3 mm. long, not str tratified though in- 
creasing in length for several successive seasons, the mouths 
dark honey yellow to snuff brown or cinnamon brown, finally 
e 
3-4 per mm., the dissepiments rather thin but entire; hymenium 
much cracked in mature specimens; spores broadly ellipsoid 
and flattened on one side, or nearly globose, brown, smoot 
5-6 X 3-4; cystidia and setae none; hyphae light to dark 
brown, mostly unbranched and with cross walls = in the 
lighter ‘tered hyphae, no clamps, diameter 2.5-3 v. 
On dead limbs and trunks of a limited sindber of small 
shrubs; including Alnus, Ilex, and Nemopanthus. 
Specimens Examined: Amherst, Massachusetts; Tripoli, 
West Fort Ann, and Bronx Park, New York; Scotia and Bear 
Meadows (three collections), Pennsylvania; Ann Arbor, Michigan. 
Ellis and Everhart report the species, as will be noted, as 
occurring on limbs and shrubs of various deciduous trees, though 
no statement is made as to just what hosts are involved. The 
species is well represented at New York but I have not studied 
the collections, though Mr. Percy Wilson who has collected it 
many times tells me that he always finds it on Ilex. This and 
Nemopanthus, a closely related genus, represent the usual hosts 
on which I have been able to discover it, though Dr. P. J. Ander- 
son sends me a Massachusetts specimen on Alnus, and I -have 
myself made one collection on that host.
