SECOTIACEAE 55 



about 75m thick, persisting in the mature and dried specimens, forming lamella-like 

 folds. Odorless when young; taste sweet and nutty like that of Boletus edulis. Edible 

 when young. 



Spores (of Xo. 7091) smooth, ovate, yellow under the microscope, 5.5-6.8 x 6.6-8/1, 

 a few irregular, larger ones. Hymenium 25-30/n thick; basidia club-shaped, 4-spored, 

 7.4-9.3|i thick, no cystidia. 



This is the first record so far as we can find of this fungus in the southeastern states, 

 but at the New York Botanical Garden we find a collection from Virginia by Dodge 

 (as 5. acuminatum). The only record we find of its occurrence in the Atlantic states 

 is from Pennsylvania (Barnett, as 5. Warnei; Peck, 1. c, 1882). It is apparently not 

 rare in the Mississippi Valley and westward, and is reported from Alabama and Texas. 

 This is the same as the plant described by Peck from Wisconsin as Lycopcrdon Warnei 

 (Bull. Torr. Bot. Club 6: 77. 1876) and later transferred to Secotium (Ibid. 9: 2. 

 ISSJi. 



We have examined and compared specimens and spores of S. Warnei from Ne- 

 braska (X. Y. Bot. Gard. Herb.; H. J. Webber, coll.) and specimens and spores of S. 

 agaricoides from Hungary (N. Y. Bot. Gard. Herb., determined by Hollos) and find 

 that they both agree with our Chapel Hill plants. We agree with Hollos that S. 

 rubigenum Harkness (Bull. Cal. Acad. Science, 1886, p. 257) is the same as the present 

 species. A specimen at the New York Botanical Garden from California, collected by 

 Harkness himself, has spores smooth, oval-elliptic, variable in size, 4.8-6.8 x 7-10.5^. 



Secotium arizonicum Shear and Griffiths (Bull. Torr. Bot. Club 29: 450. 1902) 

 seems to be a good species, as shown by the much larger spores (7.2-12 x 8.5— 15m) 

 of the type material in Washington (pi. Ill, fig. 14), and by the short, often aborted 

 columella (see note by Lloyd, Myc. Notes, p. 149). Secotium tenuipes Setchell (Journ. 

 Myc. 13: 239, pi. 107, figs. 4-8. 1907) and S. russidoides (Setchell) Lloyd (published 

 as Elasmomyces) are also good species, growing entirely concealed under leaves in 

 California. At the New York Botanical Garden is an abundant collection of the former 

 by Harper from Berkeley, California (type locality) . The plant (when dry) is small, 

 blackish red with a slender stem and a deep reddish brown gleba. The spores are 

 deep brown, smooth, ovate, 8.5-10.2 x 12-16//. Secotium australe Lloyd (Myc. Notes, 

 p. 788) is also apparently a good species, as the spores are said to be only 4-5/x thick. 

 Lloyd has seen the types of S. decipicns Peck (Bull. Torr. Bot. Club 22: 492. 1895) 

 and thinks it the same as the European Gyrophragmium Delilei (Myc. Notes, p. 150). 

 Later he uses the name G. decipiens and calls it the western form of the European 

 species (Myc. Notes, p. 196).
