Phyllosticta Monardae Ellis & Barth.; Smyth, Trans. Kansas Acad. 16: 165. 1899, 
Spots definite, circular or subcircular in form, the tissue of the infected spot becoming 
very thin and translucent, bounded by a slightly elevated border, reaching a diameter of 1-2 
mm., the infected tissue occasionally breaking out and leaving the leaf punctured with holes; 
pycnidia minute, scattered over the infected spot, usually on the upper side of the leaf, nearly 
globose and almost superficial at maturity, with a conspicuous ostiolum which reaches a . 
diameter of 10 4, the pycnidium reaching a diameter of 1504; spores ellipsoid, about 2 X 
3-5 p. 
Specimens on Nepeta Cataria are accompanied by a Pleosphaerulina which may repre- 
sent its perfect stage. Specimens on Mentha and Teucrium are accompanied by a Myco- 
sphaerella which appears to represent its perfect stage. If so. more than one species may 
be represented in what has been regarded as the same Phyllosticta on different hosts.
