CALIFORNIAN SPHJERI.E.

Sphaeria meg&locarpa. Ploro . — Perithecia superficial, very large, 
3 mill, in diameter, spherical, dull black, slightly rough, becoming 
rugulose with age ; ostiola very minute, scarcely prominent, 
surrounded by a paler areola; asci cylindrical or clavate, ’07-T3 
X ’Ol-'Olb mm.; sporidia dark brown, oval, colourless when 
young, then binucleate, •012--015 X *003-’005 mm.; parapliyses 
numerous, flexuose. (PI. 120, fig. 1.) 
On the bark of dead maple (956). 
This is a very remarkable species on account of the large size of 
its perithecia, which vary from 1^ to 3 mm. in diameter, scattered 
or crowded ; when occurring in latter condition the perithecia are 
mutually compressed. 
Sphaeria pulvis-pyxius. Pers.— On dead pine (986). 
Sphaeria xnyriocarpa. Fr. — No. 627 ; on Sambucus (944), on 
Pinus contorta (1015), on willow (1022), on decorticated black 
ash (1012). 
Sphaeria arctostaphylos. Plow.— Perithecia irregular, unequal 
in size, flattened, subrotund, collapsing, superficial ; ostiola almost 
obsolete; asci clavato-pyriform, *07 X *015-*02 mm. ; sporidia 
simple, ovate, somewhat curved, hyaline, '015--018 x ‘004--005 mm. 
On bare wood of Arctostaphylos glaucus (617). Perithecia 
accompanied by pycnidia, which contain a mass of phoma-like 
spores, oval, hyaline, *003-*004 X *001 mm. 
Sphaeria sequoiae. Plow.— Pycnidia rather large, gregarious, 
subimmersed ; spores hyaline, oval, binucleate, -003--004 mk. 
Perithecia rather large, immersed then suberumpent, seated on 
bleached spots ; asci cylindrical ; sporidia hyaline, oscurely trisep- 
tate, slightly unequal, the upper half being the larger, -025--03 X 
•008--01. 
On dead bark of Sequoia gig antea (634). Nos. 654 and 665 
appear to be conditions of the same fungus. 
Sphaeria confertissima. Plow.— Perithecia minute, densely 
crowded in patches, more scattered circumferentally, mutually com- 
pressed, subspherical; asci cylindrical, •01--008 X ’01- 015 ; sporidia 
biseriate, uniseptate, hyaline subequal, , 0015- , 002 X 005 mm. 
On cones of Sequoia sempervirens (861). 
Sphaeria sustenta. Ploro.— Perithecia immersed; ostiola burst- 
ing between the bleached fibres of the matrix ; asci cylindrical 
*15 X -015--010; sporidia ovate, dark brown then black, ’02-‘025 
X •Ol-’Oll mm. 
On bleached stems of Arctostaphylos (381). 
Sphaeria propagata. Plow . — Perithecia in lines, erumpent then 
superficial, middle sized sometimes confluent; ostiola distinct 
papillate; asci cylindrical, *05- 06 X ‘OOS-^Oll mm.; sporidia 
8 hyaline, sausage-shaped, *008-*01 X *002-*003. 
On grape cuttings (1053).
