PEZIZACEAE. 
Detonia Constellatio (B. & Br.) Rehm in Utt . 
Easily distinguished by the hook-shaped paraphyses as figured by 
Cooke, Mycog., pi. 2, fig. 81. On the ground among moss. Mile Bluff, 
Mauston, June 1909 (J. Dodge); on rich black earth, Krohn’s lake, Al- 
gonia, August 1900 (Dodge). Rehm vid. 
Detonia convexella (Karst.) 
On burned places, Devil’s Lake, June 1905, 1907. 
Detonia fulgens (Pers.) Rehm. 
The greenish spots on the exterior and the round spores, 4-6 mic. 
across, serve to distinguish this species from other orange-colored 
forms. Boudier, leones Myc., pi. 819 o, no. Jp7, and Patouillard. Tab. 
An., fig. 317, give good figures of the species. Among needles under¬ 
hemlock and white cedar, covering the ground foT several feet, 
Schmeiling’s grove, Algoma, May 1905, (Dodge.) 
Detonia laeterubra Rehm (Ann. Myc., 3: 516, 1905). 
Apothecia sessile, gregarious, at first closed globose, finally plate¬ 
shaped , then irregularly orbicular, with a distinct margin, the disk 
bright red, exterior glabrous and paler reddish, 1—4 mm. in diameter, 
fleshy. Asci cylindrical, rounded at the apex, 180—200x12 mic., 8- 
spored. Spores globose, glabrous, with one large oil globule, hyaline, 
10 mic. in diameter, monostichous. Paraphyses filiform, septate, 
hooked at the apex, 1.5 mic. thick, hyaline. II.—Cemetery woods, July 
1904 (Harper). 
Rehm, l. c. says that the species is distinguished from D. convex¬ 
ella Karst, by the color of the disk and the much smaller spores, and 
from D. gloMfera B. & C. in the color and in the hooked paraphyses. 
A second collection from Devil’s lake, July 1904 (Harper). 
Detonia mininta (Crouan) Rehm in litt. 
This species is larger than D. constellatio, 5—8 mm. broad, dark red 
to golden brown. The spores are rough and the paraphyses are 
straight, Cooke Mycog, pi. 5, fig. 17, notes these differences. On the 
ground, Mile Bluff, Mauston, June 1909 (Dodge); Rehm vid.
