The Morels and Puff-Balls of Madison. 109 



A poor specimen was once picked up on the shore of Fourth Lake. The 

 species is also reported from Wisconsin by Bundy, and has been collected 

 at La Crosse (Pammel), River Falls (King), and Sparta (Miss Rose Schuster): 

 it ranges over the entire country, from the Atlantic to the Pacific, and is 

 abundant in Europe.

2. Geaster saccatus Fr.— Outer peridium usually eight to ten lobed, 

 the sinuses extending halfway to tlie base, the lobes reflexed; varying from 

 cream-color to dark brown, the darker specimens occasionally white-striped 

 on the outside from the cracking of the oiitermost layer. Inner ijeridium 

 usually a little paler, sub-globose. Mouth iDrominent, conical, on a distinctly 

 marked disk, silkystriate, sometimes darker than the rest of the peridium. 

 Spores brown, semi-opaque, coarsely warted, 3.7 to 5 /<. PI. 1, f. 2. Abun- 

 dant in damp woods. August and September. 



This species, extremely variable in size and color, has been variously re- 

 ferred by writers. The type (represented in the Lapham herbarium, from 

 the Penokee Iron Range) is larger and coarser than our form, which corre- 

 sponds nearly to G. vittatus, Kalchbr., but the white striping of the outer 

 peridium is exceptional, for specimens growing together differ in this re- 

 S])ect, though evidently belonging to a single species. In size and general 

 appearance our plant resembles G. fimhriatus Fr., the mouth of which, as 

 indicated in descriptions and shown by European exsiccatae, is less promi- 

 nent and not on a sharply limited disk.

3. Geaster Rabenhorstii Kunze. — Small. Outer peridium at length 

 papery, whitish buff, mottled with dark brown; divided into six to eight 

 strongly reflexed lobes. Inner peridium lead-color or brown, distinctly 

 stalked with a prominent apophysis at summit of stipe. Mouth conical or 

 cylindrical, deeply furrowed longitudinally. Spores dark brown and 

 opaque, irregularly globo^^^e, coarsely papillate, 4.5 to 5 jn- — PI. 1, f- 3. —

Found once in smaU numbers under a clumi) of larches on the Univer- 

 sity grounds. I have seen tlie same plant in the collection of Professor 

 Peck, at Albany. It has doubtless often passed for a small form of G. 

 striatus (DC), and is referred to that species by Peck (38 Rep. N. Y. Mu- 

 seum, 94). It is G. Schmideli Vitt. of Winter's Kryptogamen Flora, and 

 may really be the plant figured by Vittadini. 



4. Geaster limbatus Fr.— Lai-ge. Outer peridium seven or eight lobed, 

 the segments stronglj' reflexed but with incurved tips. Inner peridium 

 brownish or gray, globose or somewhat depi'essed, raised on a short com- 

 IDressed sliglitly apophysate stipe. Mouth fimbriate, on a more or less evi-
