Ur. E. Palmer, in Mexico, agreeing accurately with specimens of this 
Uvomyc.es on Ahutilon Texense, from Dr. Fallow. In both these spec¬ 
imens, the spores are miicli more variable in size and sliape tlian one 
wmnld suppose from the description in Grevillea. They vary from nCcirly 
globose, 15—22 /J, to elliptical, or.obovate, 20—26 x It—16 :>■, distinctly 
thickened and mostly rounded at the apex, but in t!ie more elongated 
ones, obtusely pointed. In the .Mexican specimens, also, some of the 
.spores are nniseptate. with the septum often oblique, or even vertical. 
Septa were also observed, but more sparingly, in the specimens on Ahoti-

NOTEvS ON PEZIZA. 
Of all the families of Fungi, none, perhaps, is more prolific in intci - 
esting and beautiful forms than that division of the Discomycetes. 
including the Pezims. These are membranaceous, or more generally 
fleshy fungi of a discoid, or cup-shaped form, and growing either from 
the earth itself, or. oftener, from decaying wood or dead herbaceous 
stems. Like other fungi, they require for their growth and develop¬ 
ment a certain amount of moisture and of heat, though some of tin* 
species whicii grow on decaying wood appear to endure and even to tlour- 
ish at a very low temperatui-e. 't’he V>eautifid PezPtt coccine<u which 
glow’s on decaying limbs or pieces of decaying w’ood. partly buried in the 
ground, opens its scarlet-t inted cups in early spring, while yet tlie snow 
is oniy partly melted from the ground : while some of the smaller spe¬ 
cies that inhabit old logs appear in good condition late in the fall, even 
after tlie ground in the open fields is frozen. A species found by .Mr. S. d. 
ilarkness in the mountains of Utah iP. earina. —Gr. ear. spring) appears 
in full vigor on the decaying leaves of grasses still moist from the melt¬ 
ing of the winter’s snow’. A very interesting species, from its unusual 
place of growth, is described by Dr. Cooke, in the Bulletin of the Buffalo 
Soc. Nat. Sci., March, 1875. The species grow’S from the decaying petals 
of Maynolio. d’he Jlayuolra (jlauca. near the northern limit of its 
growth, blossoms early iii June. Soon after the petals have fallen, litllc 
cream-colored blotches, or swellings, will i)e noticed on some of them. 
These swellings are of a circ.ular, or subelliptica! shaj)e, and about i of 
an inch acro.ss. After a few days, they become darker colored and (piitc 
hard. Tf the alfVcted petals happen to fall on dry ground, this sw’eUing 
and discoloratiOii proceeds no further: but, as the .Magnolia grows 
in sw’ampy ground, many of the affected petals fall in the mud or water, 
and, when the leaves fall in the autumn, are pressed down and buried 
completely in the mud. w here they lie thrmigh the wilder. But wdien 
the siiring returns again, and the .Magnolias })ut forth their fragrant
