This is a pretty fungus and very showy, even in the the dried 
state, by reason of the clear golden-yellow color of its spores. 
^ciDiuM IsoMERiNUM.— Spots pallid, thickened; peridia amphi- 
genous, short,^ scattered or crowded; spores subglobose, ovate or 
elliptical, whitish (when dry) .0008 to .0011 of an inch long, epispore 
thin.

Sometimes the fungus occupies nearly the whole leaf, which, in 
such a case, is considerably thickened and distorted. 
^ciDiUM Anisacanthi. — Spots none or indistinct ; peridia 
amphigenous, elongated, pinkish -gray, crenafely lacerated at the apex; 
spores very variable in shape, subglobose, ovate, elliptical, oblong or 
oblong-pyriform, sometimes pointed at one end, yellowish or brown- 
ish yellow (in the dried state) .0009 to .0018 of an inch long, .0008 
to 00095 broad.

Sph^rella Arbuticola. — Maculicolous, spots suborbicular, un- 
equal, blackish or subcinereous, brown on the lower surface of the 
leaf; perithecia minute, black, epiphyllous, scattered or collected in 
small groups, piercing the whitened epidermis; asci oblong, some- 
times narrowed above, .0016 to .005 of an inch long; spores crowded, 
narrow, colorless, uniseptate, .00045 to .0006 of an inch long, ,00016 
broad.

The septation of the spores is rather obscure, but this is probably 
due to their being immature. The epidermis is slightly elevated 
around the perithecia and has there a whitish appearance. 
Microsph^:ria erineophila. — Mycelium arachnoid, subpersis- 
tent; perithecia .003 to .004 of an inch broad, sometimes collapsed 
or peziz^eform; appendages 6 to 12, shorter than or about etpial to 
the diameter of the perithecia, colored, the tips paler and two to three 
times dichotomous; asci 4, sometimes 3 or 5, eight-spored; spores 
.0008 to .0009 of an inch long, .00045 ^^ -0005 broad, usually con- 
taining one or two large nuclei. 
On the Erineum of beech-leaves. Illinois. F. S. Earle and Prof. 
A, B. Seymour. 
This fungus is closely related to M, penicillata^ of which perhaps 
It may be a mere variety, but it is readily distinguished by its colored 
appendages and nucleated spores. Its habitat is very peculiar. In 
all the specimens seen it occurs only on the Erineum. 
Proterogyny in Spartina juncea.— Has this been noticed? My 
attention was attracted to it this morning on the beach here. The 
plumose stigmas of all the spikes on a particular plant are protruded, 
while the stamens are still full and retained in the palets. l\\ other 
plants where the purple anthers are ])rominent, I find the stigmas 
withered.
