SPORONEMA CAMELLIAE n. sp. 
Epiphyllous on large white brown-bordered spots or areas, — 
2-5 cm. in diameter; perithecia thickly scattered, buried, eleva- — 
ting the epidermis, orbicular or somewhat elongate, usually n= 4 
mosely dehiscent, occasionally stellate-laciniate, becoming discoid, | 
of firm cellular texture, about 200 #7; spores cylindric, ends ob- | 
tusely rounded, sometimes curved, usually bi-guttate, 12-18x 4-5 
_ basidia short and thick, about equalling the spore, usually simple. | 
On living leaves of Camellia Japonica, Auburn, Ala., March 
and April, 1896. J, S. Burton. : 
The spots resemble very closely those caused by Pestalozau 
Guepini Desm. 
SPORONEMA ILICIS n. sp. 
Epiphyllous on large deadened and whitened areas, usually — 
involving the apical portion of the leaf; perithecia often some- 
what concentrically arranged, or thickly scattered, large, brown, — 
membranous, buried in the epidermis and coming off with it, — 
usually somewhat elongate, elevating the epidermis and at length — 
cracking it longitudinally or stellately ; spores continuous, elliptic, — 
hyaline, on short simple hyaline basidia about 12-15 x 4-6 ps. 
On languishing leaves of //exr opaca, Auburn, Ala., Decembert> — 
1895 ; January, February and March, 1896. Underwood & Earle. 
From a fourth to a half of the leaf is usually dead and con- — 
spicuously whitened. The living portion is usually bounded by | 
a broad intermediate dark purplish border. The gross appearance — 
is much like Phyllosticta opaca E. & E.,N. A. F. 3443, but the | 
spores are entirely different. é
