HELOTIACEAE 
Pezizella subcinerea Rehm (Ann. Myc., 2: 37, 1904; 9, 1907). 
Apothecia scattered broadly sessile, at first globose then ureeolate, 
orbicular, disk subcinereous, exciple glabrous with elongated cells at 
the base, context almost prosenchymatous toward the margin, yellow¬ 
ish, hyaline within, waxy, when dry involute, 1-2 mm. in diameter. 
Asci clavate, rounded at the apex, 50-55x6-7 mic., 8-spored. Spores 
oblong, straight or slightly curved, 1-celled, hyaline, 6-8x2 mic., dis¬ 
tichous. Paraphyses filiform, hyaline, septate, prominent, 3 mic. 
thick. Pore of ascus I-f. 
On decayc-d wood, Madison, 1902 (no. 325, Harper). Differing from 
Mollisia cinerea in the structure of the thicker apothecia. Approach¬ 
ing Pezizella subcarnea (Schum.) Rehm. Known only from the type 
locality and collected but once. 
Arachiiopeziza Aurelia (Pers.) Fckl. 
These specimens show the spores have appendages as figured by 
Rehm, Disc., p. 694, figs. 1-5. Currey, Linn. Trans., XXIV, PI. 51, figs. 
15, 16, and Patouillard, Tab. An., fig. 285, represent these forms ex¬ 
cept as to the appendages of the spores. On acorn cups, Devil’s Lake, 
July 1903. 
Cliolorsplenmm aeruginascens (Nyl.) Karst. 
The spores of these plants are only 1—1.5x6—7 mic. and have two 
to four greenish granules. So far as I find this species differs from 
the following only in the size of the spores. In the mature spores w r e 
find, that there is a distinct septum, the v. 7 all appearing in sections as 
a fine straight line. On oak stub, Mauston 1909 (Dodge); on dead 
alder limbs, Serrahn’s swamp, Algoma, September 1909 (Dodge). 
Cliorospleniimi aeragmosum (Oed.) De Not. 
Like the preceding species this blue-green fungus colors both heart 
and sap wood a greenish blue. The mature spores, 10-14x2.5-3.5 mic., 
are also septate as figured by Saccardo, Fungi Ital., PI. 1348. Boud- 
ier, leones Myc., pi. 4S5, shows the general appearance of the' species 
as we find it. Blue Mounds, July 1902 and August 1903; Crandon, 
August 1903 (^Neuman); Eagle Heights, July 1904; Ladysmith, 
August 1905; (no. 360, Neuman); Detjen’s swamp, Algoma, August 
1905 (Dodge); Devil’s Lake, July 1907; Blue Mounds, August 1908; 
Lake Nehagaman, August 1908; Krohn’s Lake, September 1912 
(Dodge).
