On stems of Vaccininm Myrtillus. Appin, Captain Carmichael — 

 This is a very distinct species, a true Hysterium and quite dificreut 

 from H. degenei'anSy a species included in Loudon's list. In its early 

 stage of growth it a[)pears like a brown spot ; as it swells, the cuticle 

 is raised up and at length splits longitudinally and for a long time 

 closely covers the two lobes of the perithecium. H. pulicarcj Johnst. 

 Fl. Bene. v. 2. p. ISO, is probably this species.
