Scattered or gregarious, perithecia prominent but long covered 

 by the thin epidermis, orbicular, at length subdepressed, bright- 

 coral-red, smooth, soft, perforated by an obscure ostiolum, 400 

 mic. in diameter; asci numerous, cylindrical, with a stem-like 

 base, 100 X 8 mic; spores obliquely i-seriate, hyaline, minutely 

 granular within, i-septate, subelliptical, ends acutish, 17X4 mic. 



On dead stems of Pedicularis crenulata. 



Type locality: Colorado. 



Distribution : Known only from type locality. 



Specimens examined: Colorado, Baker & Earle 230 (type). 



The species is distinct in the large perithecia and spores. 



2. Nectriella peponum (Berk. & Curt.) 



Nectria peponum Berk. & Curt. Grevillea 4: 16. 1875. 



Nectria perpusilla Berk. & Curt. ; Ravenel, Fungi Car. Exsicc 



51.. 



Perithecia scattered or gregarious, at first covered by the thin 

 epidermis, becoming subsuperficial, but nestling in minute cavi- 

 ties in the substratum ; ovoid, with a prominent, obtuse ostiolum, 

 175 X 200 mic, bright red, nearly scarlet, component cells of the 

 perithecial wall distinct, 5 mic. in diameter; asci clavate, 35-40 

 X 5-6 mic, 8-spored; spores i-septate, fusoid, hyaline, 10 X 4 

 mic. 



On dead gourds. 

 Type locality: South Carolina.

 Exsiccati : Ravenel, Fungi Am. Exsicc. 338 and Fungi Car. 

 Exsicc. 51. 



The species very closely resembles Nectria sanguinea (Bolton) 

 Fries, but differs in its habitat and subhypodermal character, as 

 well as in the color of the perithecia.
