In external appearance this species agrees entirely with Asterinella 
lugubris Syd. from the same host. It differs, however, by the smaller 
perithecia which are usually not much elongated, by the smaller asci and 
sporidia, and in the absence of paraphyses. The pycnidiospores mentioned 
in our description seem to belong to the Asterinella, as they are formed 
m pycnidia quite similar to the perithecia of the ascigerous stage.
