New Species of Fungi 
169 
in the center, with a narrow, slightly raised, darker border, 2-5 
mm. diam., subconfluent, scattered over the green parts and also 
over brown, dead areas of the leaf. Perithecia amphigenous, 
innate in the substance of the leaf, 100-110 fx diam., the apex 
erumpent, broadly perforated and finally collapsing, cirrhi light 
horn-color. Sporules filiform, curved, faintly guttulate hyaline, 
35-40 X lJ-2/X. 
S. similacina Dur. & Mont, has no spots and differs otherwise. 
Micropera vaccinii E. & E.— On old stems of Vaccinium 
corymbosum, Millers, Ind. Oct. 1903. (E. T. & S. A. Harper, 
89°). 
Perithecia ovate-conic, flesh-color, subcuticular, erumpent in 
a small (1 mm.) black tubercle. Sporules arcuate, ends acute and 
hyaline, 40-50 x 3 fx. 
Myxosporium fumosum E. & E.— On dead limbs of Tilia 
americana. River Forest, Ill. May 1903. (E. T. & S. A. Har- 
per, 799). 
Acervuli sunk in the surface of the inner bark, pale at first, 
becoming black, subcircinately arranged or scattered, discharging 
the conidia through a common opening and forming a depressed- 
conical mass of a sooty-black color on the surface of the bark. 
Conidia lunate, continuous, hyaline, abruptly contracted and sub¬ 
acute at the ends, 12-15x4-6/x; much resembling those of Mar- 
sonia populi (Lib.). 
Gloeosporium heterophyllum E. & E.— On leaves of 
Artemisia heterophylla, near Claremont, Calif. Jan. 1. 1904. 
(C. F. Baker, 3982). 
Acervuli sunk in the substance of the leaf on black spots 2-3 
mm. diam. soon erumpent, subconical, black. Conidia oblong or 
clavate-oblong, guttulate, curved, hyaline, 14-18 x 3-5 fx, ends 
obtuse. 
Gloeosporium maculosum Sacc. on Artemisia vulgaris s on 
the stems, has smaller acicular conidia 18-10 x 2/x) and the 
acervuli are scarcely erumpent. 
Amphisphaeria granulosa E. & E.— On old oak barrel 
staves lying on the ground. Lyndonville, N. Y. Sept. 1900. 
(Dr. C. E. Fairman). 
Perithecia erumpent-superficial, globose or depressed-glo¬ 
bose, granular-rougbened, about mm. diam., quite evenly and 
thickly scattered; ostiolum minute, papilliform. Asci cylindrical, 
short-stipitate, 65-70 x 4 fx, obscurely paraphysate. Sporidia un- 
iseriate, oblong, uniseptate, scarcely constricted, pale-brown, 
slightly narrowed at each end, 10-12 x 3-3^. 
A.confertissima E. & E. has rather smaller perithecia and 
broader sporules. A. conferta Sz. has the perithecia seated on a 
radiate-fibrose mycelium but is otherwise much like this.
