Urnnla terrestris (Niessel) Sacc. 
The bright sulphur color of the disk is in striking contrast to the 
rough, dark-brown exterior. The paraphyses may be either T-shaped or 
merely hook-shaped at the apex. Among needles and moss on old 
coniferous trunks and roots, Perry’s swamp, Algoma, August 1909 (J. 
Dodge). 
PMcaria alutacea (Pers.) Fckl. 
Rehin, Ann. Myc., 7: 526, 1909, found that tjxese specimens differed 
from the European forms in having only one large oil globule in the 
spore and in being much rougher. The cups are sometimes divided 
on one side and are often alutaceous. Cooke, Mycog.,pZ. 54, fig. 214> and 
Boudier, leones Myc., pi. 327, no. 238, give good figures. Krohn’s lake, 
Algoma, Amgust 1909 (no. 1856, Rehm. Asc., Dodge); Devil’s lake, 
June 1909. 
Plicaria foadia (Pers.) Fckl. 
Some forms of our plants show a purplish or even violet tinge. Fig¬ 
ures usually given for the American forms agree well with the large 
plants found in woods; cf. Boudier, leones Myc., pi. 283; Berkeley, 
Out., pi. 23; fig. 4‘ Specimens distributed as No. 1860, Rehm Asc. Exs., 
from rich black soil near Krohn’s Lake are very small and almost 
black. These are quite different plants, but may be the same species.

Plicaria chrysopela (Cooke) Rehm. 
On flower pot in grrenhouse, Madison, January (no. 414, Harper), 
Rehm vid. Cooke describes the spores as 12x6 mic., Mycog., p. 156. 
Rehm, Disc., p. 1005, gives the measurements 15-17x8 mic. The spores 
of these specimens are 19-20x10 mic. Pustularia vesiculosa is often
