In dark, sooty, epiphyllous blotches. The spores agree well 
with the figures and measurements of Spegazzini. (Fungi 
Chilenses p. 190), but the number of septa is often as much 
as eleven with 3 to 4 more close septa at each end. The my- 
celium which is associated with it is also more beaded than in 
the figure of Spegazzini.
