Dodge—Wisconsin Discomycetes . 
1033 
subcurved, 1-celled with a large central oil globule, hyaline, 20-24x5-6 
mic., monostichous. Paraphyses filiform, septate, hyaline, 2.5 mic. 
thick, apex obtuse, 3 mic. thick. On decaying wood of conifers buried 
in the ground. 
“A very beautiful discomyeete with large spores similar to Ciboria 
Dallasiana E. & E. (Sace. Syll. XVIII, p. 45), but different in the color 
of the disk and does not have spindle-shaped spores; the paraphyses 
are also different.” 
Small plants are similar in appearance to what is commonly called 
Geoyyxis nebulosa (Cooke) Sacc. In mature plants the apothecia are 
nearly plane or salver-shaped. The writer found the spores were often 
larger than the measurements given by Rehm. The spores of G, nebu- 
losa are rough (Cooke, Mycog. fig. 163), while those of Ciboria fusco- 
cinerea are perfectly smooth. See also under Tarzetta cinerascens

Ciboria pachyderma Rehm. 
Madison (no. 419, Harper). Rehm vid. 
Ciboria pygmaea (Fr.) Rehm. 
These specimens were at one time identified as Dasyscypha pygmaea 
by Morgan. The figures in Linn. Trans . XXV, p. 432, pi. 55 , figs. 
7—9 , IS , seem to be fairly good for these forms. Devil’s Lake, July 
1903; Madison, June 1906. 
Ciboria renispora (Ellis) Sacc. 
On oak leaves, Palmyra, October 1903 (Harper) Rehm vid. 
Ciboria snlfurella (E. & E.) Rehm. 
Durand, Bull. Tor. Bot. Club, 29: 461, 1902, gives a good description 
of this species. The characteristic sulphur color is entirely lost in 
drying and the specimens generally become dark brown, almost black. 
This no doubt accounts for a second description of the species under 
the name C. tabacina Ellis & Holw. in Bull. No. 3, Minn. Nat. Hist. 
Surv., p. 35, 1886, where it is stated that the description of the colors, 
etc., was taken from the dried specimens. An examination of the type 
specimens shows that the species are identical. The type material 
distributed as no. 1880, Rehm Asc. Exs. as C. tabacina (?), were all 
collected on ash petioles, Perry’s swamp, Algoma, August 1909

Gtborfa snbrabescens (Rehm.) Ann. Myc., 7; 524, 1909. 
Apothecia gregarious, occasionally many closely aggregated together 
on the thickened bark of decaying roots, at first globose, closed, then
