3] 8 MINNESOTA BOTANICAL STUDIES. 



On ground in woods often among moss. Usually on sandy 

 soil. 



Hennepin, July 1903, C. C. Conser ; Washington, Aug. 

 1903, Wheeler; Ramsey, Sept. 1903, Freeman 1380. 



The collection 1380 Freeman agrees in color and form with 

 L. cMorocephala. The stipe is green and only slightly lighter 

 than the cap and the plants are more slender. As many grada- 

 tions may be found between this and typical L. lubrica forms 

 so all of the above specimens have been listed under L. lubrica. 

 The dried material from collection 1380 Freeman shows a yel- 

 lowish stipe. 



The specimens agree with Thuemen Fungi Austr. 517, the 

 average spores of which measure 20 x 5 mic. ; Sydow Mycoth. 

 March 278, 667, the average spores of which measure 20 x 4 

 mic.; Thumen Mycoth. Univ. 1112, the average spores of 

 which measure 18-20 mic. x 4-5 mic. 



They agree with the descriptions and figures of Rehm Krypt. 

 Fl. Vol. I. ubi.Jfg. 1-4. 1896 and of Massee Monograph of 

 Geoglossaceae, Ann. Bot., Vol. n, -pi. XIII., Jigs. 61, 65.

 spores of which measure 35-45 x 2 mic. ; Ellis and Everhart 

 N.A. Fungi 3533, the spores of which measure 35-40 x 2 mic. ; 

 D. Saccardo Mycoth. Italica 873, the spores of which measure 

 35-45 x 2 mic.
