margin; pycnidia occurring on the upper side of the leaf, globose-conic, brown, reaching a 
diameter of 90-110 uw; spores minute, very numerous, hyaline, 1 & 4.5-6 pu. 
ON BuXACEAE: 
Pachysandra procumbens Michx., North Carolina. 
TYPE LocALITy: Biltmore, North Carolina, on Pachysandra procumbens.

135. Phyllosticta cylindrica Sacc. & Syd. in Sace. 
Syll. Fung. 14: 853. 1899. 
Phyllosticta Heucherae Ellis & Ev. Am. Nat. 31: 428. 1897. Not P. Heucherae Brunaud, 1890. 
Spots subcircular but rather indefinite in outline, reaching a diameter of about 1 cm., 
becoming blackish by reason of the large number of pycnidia, about equally visible on either 
side of the leaf; pycnidia closely gregarious, reaching a diameter of 100-180 #; spores abun- 
dant, minute, rod-like, about 1 < 5-6 n. 
ON SAXIFRAGACEAE: 
Heuchera cylindrica Dougl., Idaho. 
TYPE Locality: Near Lake Waha, Idaho, on Heuchera cylindrica, 
DISTRIBUTION: Known only from the type locality. $ 
136. Phyllosticta hibiscina Ellis & Ev. Jour. Myc. 4:9. 1888. 
Phyllosticta Hibisci Peck, Ann. Rep. N. Y. State Mus. 42: 125. 1889. 
Spots circular or subcircular or occasionally slightly irregular in form, yellowish or whit- 
ish, usually surrounded by a narrow dark-brown border, the infected tissue becoming very 
thin and often breaking out, reaching a diameter of 1 cm. or occasionally larger, indistinctly 
visible on the under side of the leaf; pycnidia rather numerous, scattered over the infected 
spot, usually restricted to the upper side of the leaf; spores ellipsoid or fusoid, 1-2 X 6-8 p. 
On MALVACEAE: 
Hibiscus Moscheutos L,., Connecticut, Louisiana, New Jersey. 
Hibiscus mutabilis L., Louisiana, 
Type LocaLity: Louisiana, on Hibiscus mutabilis. 
DIsTRIBUTION: Connecticut, New Jersey, and Louisiana. 
Exsiccati: Ellis & Ev. Fungi Columb. 1559. . . 
A specimen on A butilon umbellatum Sweet, from Porto Rico, referred to this species by F.L. 
Stevens, conforms well in spore-characters but is much more indefinite, so that the determination 
is doubtful. 
137. Phyllosticta Antirrhini Sydow, Hedwigia Beibl. 38: 134. 1899. 
Phoma sp. Stewart, Bull. N. Y. Exp. Sta. 179: 110. 1900. 
Spots marginal or apical, reaching a diameter of 1 cm., definite in outline, occasionally 
subzonate, pallid above, greenish below; pycnidia occurring on the upper side of the leaf, 
globose, reaching a diameter of 100-180; spores ellipsoid, hyaline, 1.5-2 X 4-6u. 
On SCROPHULARIACEAE: : 
Antirrhinum majus L. (cult.), Indiana, Massachusetts, New York. 
Type LocaLiry: Europe, on Axtirrhinum sp. 
DISTRIBUTION: Massachusetts to Indiana; also in Europe. 
ILLUSTRATIONS: Phytopathology 9: 315-322, f. 1-8; 10: 243-247, f. 5-8. 
This species has been reported by Guba and Anderson as occurring on the stems of the above 
host where it causes a damping-off disease of the young plants. These observations have 
been confirmed in culture by E. M. Smiley (Phytopathology 10: 232-248). 
138. Phyllosticta erratica Ellis & Ev. N. Am. Phyllost. 43. 1900. 
Spots usually marginal, dark-brown, often entirely surrounding the leaf and gradually 
encroaching on the living tissue, the boundary line indefinite; pycnidia sparingly scattered 
over the infected spot, erumpent, reaching a diameter of 80 »; spores rather abundant, sub- 
globose or ellipsoid, granular within, reaching a diameter of 6-8 u 
On ULMACEAE: 
Ulmus americana, Alabama. 
Ulmus fulva Michx., Alabama. . 
Typr Locality: Alabama, on Ulmus americana. 
ISTRIBUTION: Alabama. 
Billie loc. cit., also records this species on Rosa sp and Thea sp. from Alabama. The occur- 
rence of the same species on such widely different hosts is rather unusual.
