On young living larch branches, Queen's Cottage Grounds. 



This fungus is a true parasite, but does little or no direct 

 damage. Indirectly, however, it is sometimes the cause of serious 

 injury as through the minute cracks formed in the living bark, 

 and the extrusion of sap and resin, the spores of the "Larch 

 canker fungus (Dasyscypha calycina, Fckl.) often effect an 

 entrance into the tissues of the host, and as a rule canker follows. 



The minute black conidiophores occur in dense clusters at 

 ditterent points on the branch. Allied to Exosporium Tiliae, 

 Link, but at once distinguished from this and every other known 

 species by the fusiform conidia.
