1921] MILES—LEAF SPOTS OF ELM IQr 
Under this name I am recording the occurrence of a fungus having the 
following characteristics: Spots indefinite, immarginate, orbicular, light- 
brown, becoming cinereous above and lacerate, finally falling away in frag- 
ments, 3-7 mm. in diameter, sometimes confluent; pycnidia epiphyllous, 
scattered, black, globose to depressed, 60-80 uw; sporules globose to elliptical, 
olivaceous-hyaline, continuous, 3-62-34. On Ulmus americana, Tisch 
Mills, August 3, 1917. Ulmus racemosa, August 5, 1917. This is probably a 
member of a group of forms of which various names have been applied in 
Europe and America 
It has also been reported from a number of other states, among 
them Michigan, where it is said to occur on Ulmus fulva. 
PHYLLOSTICTA CONFERTISSIMA Ell. and Ev.—Spots red-black, 
amphigenous; pycnidia 75 «in diameter; spores allantoid, hyaline, 
3-4X1 uy. On leaves of Ulmus fulva in Kansas. 
Puoma crincta B. and C.—Spots irregular, depressed, with a 
white border; spores oblong, narrow, 6-8 u long. Reported on 
leaves of Ulmus americana in South Carolina. 
EXCIPULA ULMICOLA Schw.—Causes widely expanded indeter- 
minate spots on the upper side of the leaf, becoming somewhat 
spotted with gray on both sides, with a broad, fuscous margin; 
pycnidia copious, immersed, excipuloid, punctiform, black, de- 
pressed in center and becoming gray. Reported as somewhat rare 
on cast-off leaves of Ulmus fulva about Bethlehem, Pennsylvania. 
CoRYNEUM TUMORICOLUM Peck.—Forming scattered, suborbic- 
ular, pale spots, bounded by a red-brown border on living leaves 
of Ulmus americana in the Adirondack Mountains. 
SPHAERIA APERTIUSCULA Schw.—Scattered, fuscous-black, 
minute, arising from the swollen parenchyma; at first innate, 
at length opening by a very wide mouth, but evacuate within; 
resembles a small Peziza. Recorded as occurring on the lower 
side of leaves of Ulmus fulva in New York. 
RuytisMA Utmr Fr.—Minute, difformous, gyrose with an 
elevated margin, at length dehiscing labiately. Reported on 
leaves of Ulmus in North America. 
MELASMIA ULMICOLA B. and C.—Spots reddish, indefinite; 
pycnidia punctiform; spores minute, oblong-botuliform. Cook 
(0) speaks of it as the Melasmia stage of Rhytisma Ulmi, and 
reports it as very common in New Jersey.
