﻿Cordyceps stylophora Berk. & Br. in Minnesota. 



On the 28th of April, 1898, I found a single specimen of this 

 rare American species growing upon the larva of a carabid beetle 

 among Hypnum at Minnehaha Falls near Minneapolis. The 

 plant was originally described from specimens of Ravenel collected 

 in South Carolina and was distributed by Ravenel in Fung. Car. 

 Exsic. 5 : no. 49. It is figured in Berkeley's paper, * but the ripe asci 

 were not seen by the authors. Another figure of the plant is given 

 by Massee f in his monograph of the genus, and in this paper the 

 first measurements of asci and spores are recorded from the type 

 specimen in the Kew Herbarium. I do not find that the 



M 



sota plant conforms exactly to these measurements. According 

 to Massee the spores are 125-135 X I ft and the component cells 



11 about 3.5 /jt long." The Minnesota plant shows spores 1 50-180 



7 ji long. In all other respects the 

 plant found at Minnehaha agrees quite exactly with the descrip- 

 tions and figures. In Saccardo % and Ellis § no microscopic 

 measurements are given. This new discovery is apparently in- 

 dicative of a comparatively wide range for the species.
