Apothecia erumpent through the outer bark of the host, 

 single, or occurring in clusters, often so numerous as to form 

 congested masses many cm. in extent and often almost entirely 

 surrounding the branches on which they grow, the individual 

 apothecia at first nearly globose, opening at the top so as to leave 

 an irregular margin, at maturity about 1 mm. broad and the 

 same in height, brownish, furfuraceous externally and longitu- 

 dinally striated; hymenium whitish, or bluish-white; asci clavate, 

 reaching a length of 130 ^ and a diameter of 7-8 tx, 8-spored; 

 spores fasciculate in the ascus, subfiliform, tapering toward 

 either end, sharp-pointed, 3-4 X 65-85 jx, becoming 7-septate at 

 maturity and often slightly constricted at the septa, hyaline; 

 paraphyses abundant, filiform. 



Pycnidia often accompanying the apothecia, at first closed, 

 becoming shallow cup-shaped, usually black; pycnospores fusi- 

 form, straight, or slightly curved, 3-septate, 3-4 X 28-30 ji. 



On branches of Salix. 



Type locality: Europe. 



Distribution: Ontario and Colorado; also in Europe.

This species was collected in abundance on willow at Tolland, 

 Colorado by the author in company with Ellsworth Bethel in 

 1910 and described as a new species, Godronia Betheli. Later 

 study revealed the fact that Lasiosphaeria striata Ellis & Ev. is 

 identical but owing to the fact that it had been placed in the 

 Sphaeriales it had been overlooked. The young apothecia are 

 strongly constricted which doubtless accounts for the fact that 

 Ellis placed it in that group. Later study has revealed the fact 

 that both Ellis and Everhart's species and the species of the 

 writer are identical with Cenangium fuliginosum of Fries.
