15. Ltcoperdon glabellum Pk. — Depressed globose, or elongated and 

 stipitate, more or less umbonate, three-fourths to two in. high. Peridium 

 buff, very finely furfuraceous. Spores and capillitium purple or more or less 

 brown, the former 5 to 6 /<, with coarse warts, and short-pedicelled. — PI. 3, 

 f. 5. — On the ground in woods, accompanying i. gemmatum; 'River ¥&]!& 

 {King). 



Tulostoma finibriatimi Fr., a small puff-ball raised on a solid cylindrical stipe about 

 one-eighth in. in diameter and as much as an inch long, may be recognized by its subglobose 

 more or less granulated peridium, opening by a small scarcely protruding fimbriate mouth, 

 brick-colored, remotely spinose, round spores 4-5 f.i in diameter, and pale blunt anasto- 

 mosing capillitium. I have received it in quantity from Professor King, of River Falls. 



SECOTIUM. 



1. Secotium ACUMINATUM (Mont.) {S . Tlvunii Sclvalzer . S.WarneiVk.) — 

 Short stipitate, subglobose to conical ovoid, rounded or frequently more or 

 less acuminate above. 



Peridium rather leathery, dull yellowish-white, passing into buff; smooth 

 or mostly with crenated scale-like elevations often free at their lower 

 edge, dehiscing ii-regularly about the stipe, which is prolonged through 

 the sporiferous portion as a stout columella one-fourth to one-half in. 

 in diameter, and firmly united with the peridium at apex. Spore-bearing 

 mass snuff-brown, extending laterally from the columella in a series of 

 eroded friable thin gills. Spores yellow-brown, smooth, stalkless; extremely 

 variable, spherical, ellipsoidal, or more or less regularly ovoid, 4-9x6-14, 

 raost commonly 6x8 /-i. — PL 2, f. 7. — Abundant in late summer and fall in 

 open pastures, etc. My largest specimens were obtained on the bare 

 ground in a potato patch. 



Reported from Wisconsin by Bundy {I. c. 399, — the specimens preserved 

 in hb. Peck), and Peck (Bull. Torrey Club), and included in the collections 

 of Dr. Brown, of Sheboygan, and F. H. King, of River Falls. Edible 

 ■when young. 



According to Schulzer von Muggenburg (Hednigia, 1883, 43), this species, 

 described by Peck, as Lycoperdon Warnei (Bull. Torrey Bot. Club, vi, 77), 

 Podaxon Warnei (U. S. Sp. Lycoperdon, 34), and Secotium Warnei (Bull. 

 Torrey CI. ix, 2), is identical with the European S. Threnii Schulzer, which 

 is ref errible to >S'. Acuneinatum (Mont.) Tul. S. Szabolcsense Hash, judg- 

 ing from his figure and the abstract of his paper in Jost's Bot. Jahres- 

 bericht for 1876, p. 161, must be extremely closely related.
