TENTH REPORT. 
pared by slicing and frying in egg and bread crumbs. Peck quotes from 
the Country Gentleman an account of a specimen eight feet in circumference 
and weighing forty-seven pounds. This is the extreme size, though they 
occasionally grow to a diameter of 1 . 5 to 2 feet in our area. 
(b) Calvatia cvathiforme (Bose.) (In sense of Morgan.) 
Other names: 
Calvatia lilaeina (B. and M.) Lloyd. (Lloyd insists that this name 
should be used instead of the above.) 
Lycoperdon cvathiforme Bose. (In Peck.) 
Lycoperdon fragile Vitt. (The European name, according to Lloyd.) 
Bovista lilaeina B. and M. 
Lycoperdon lilacinum (B. and M.) Speg. (In Engler and Prantl.) 
The upper part falls away leaving a wide cup filled with purplish spores 
and capillitium; sometimes a strong lilac tinge is apparent. Spores globose, 
distinctly warted or echinulate, 5-7 m diameter. Throughout the state. 
Mostly in fields. Common around Ann Arbor. 
(c) Calvatia caelata (Bull.) (In sense of Lloyd and Morgan.) 
Other names: 
Lycoperdon caelatum Bull. (In Engl, and Prantl, Massee, Peck.) 
Lycoperdon favosum Rostk. (In Trelease.) 
Fields and roadsides. Also found on a well-kept lawn at Houghton. Thru- 
out the state. Often somewhat areolate, like the preceding, due to the par- 
tial separation of the cortex. Spores globose, 4-4.5 mic. 
(d) Calvatia elata Mass. (In sense of Morgan.) 
Other name: 
Calvatia saccata Vahl. Said to be the European form of our plant. 
Our plants have some of the characters of both C. saccata and C. elata. 
The stem of this Calvatia is more differentiated, and deeply wrinkled, than 
the preceding. Low grounds, 1st Sister Lake, Ann Arbor. 
6. Bovistella. (In sense of Lloyd.) 
(a) Bovistella pedicellata (Pk.) Lloyd.

Cortex of long spines, falling away and leaving a smooth inner peridium. 
Gleba olive or brown. Spores globose, smooth, 4-5 mic., with very long- 
pedicels, 20-24 mic. long. The only other plants in our flora with such 
shaggy spines on the peridium are Lycoperdon pulcherrimum B. & C. and 
Lycoperdon echinatum Pers. In woods; throughout the state. Not very 
common. 
(b) Bovistella ohinesis Ell. & Morg. has not been reported from our flora. 
Other names: Scleroderma Ohiense DeToni. (In Saccardo.) Mycen- 
astrum Ohiense Ell. & Morg. (In Jour, of Mycol. Vol. I.) 
“Cortex a dense floccose coat, leaving a smooth pale brown or yellowish 
surface to the inner peridium . ” Gleba olive or brown. Spores 4-5, mic. 
globose, with pedicels 10-12 mic. long. Fruit-body plicate underneath with 
a thick, cord-like root. 
(c) Bovistella echinella (Pat.) Lloyd. 
A rare puff-ball, sent to Lloyd from Michigan by Longyear; very small, 
half a centimeter in diameter, dark reddish brown. Cortex of minute tufted 
spines, in patches. Sterile base none. Gleba olive-brown. Spores glo- 
bose. 4_5 mic. smooth, with pedicels about 10 mic. long. Usually grows on 
Funaria hygrometrica.
