Plate I, Fig. 5, is from a camera lucidu drawing of a mature

 which was kindly loaned me by Rev. J. B. Ellis. A majority 

 of the perithecia were young and possessed straight appendages. 

 Figs. 6, 7 and 8 are from the same specimen. Figs. 9, 10 and 

 11 are from a South Carolina specimen; all from camera lucida 

 drawings.
