Sclerotinia tuberosa (Hedw.) Fckl. 
Milwaukee, April 1905; Madison, May 1909 (R. Allen); Cemetery 
woods, Madison, June (J. Dodge); The Dells, Kilbourn, June 1909 
(Dexter). 
Sclerotinia Wisconsinensis Rehm (Ann. Myc., 6: 317, 1908). 
Apothecia from a suborbicular sclerotium convex below in upper 
part plain or umbilicate, exterior black, interior white, wrinkled when 
dry, 3-6 mm. broad, 2.5-3 mm. thick, in clusters of 2-5, rarely solitary. 
At first spheroid, then disk-shaped, with a thin margin,1.5-3 mm. broad 
and high, yellowish-brown, glabrous, when old tawny brown with a long 
stipe. Stipe cylindrical, about 0.15-0.2 mm, thick, expanding belpw the 
excipulum, 2-3 cm. long, glabrous, erect, curved, brownish-yellow' Apo- 
thecium with the stipe longitudinally wrinkled when dry, the disk var¬ 
iegated whitish. Asci clavate, apex rounded, 150-180x12-15 mic., 8— 
spored. I-f. Spores fusiform, more or less rounded at the the ends, 
generally with one or two large oil globules, hyaline, 20-22x7 mic., 
monostichous, rarely distichous. Paraphyses filiform, projecting, ob¬ 
tuse, septate, hyaline, 3-4 mic thick. In damp woods, Madison, March 
1908 (no. 75, Arzberger). 
“The specimens were slightly imbedded in earth mixed with decayed 
plants and small dry twigs of ash. Isopyrum biternatum and Os- 
morrhiza longistylis grew abundantly in the neighborhood, but Arz¬ 
berger found no connection between these plants and the sclerotia, 
though this must probably be assumed to exist. &. gracilis Clements 
(Sacc., Syll. XVI, p. 723) is distinguished by its larger lobed sclerotia 
and its spores 26-32 mic. long.”
