On branches of beech. [Mid. Carolina.]
The branches on wbiob it grows, and which it generally surrounds, are of
a bright red-brown. The perithecia vary in size andin the number grouped
together, which is from 3-8, tbeir ostiola collected in an erumpent brown
disc. Sporidia ('0003-'0004 in.) -0076-'01 m.m.

Perithecia about six together, minute, ovate, circinating, converging,
as well as the round, somewhat attenuated, erumpent
ostiola; sporidia dark brown, suhcymbiform, irregular, frequently

The peritbecia are under the bark so as not to be seen above, except by tbe
undulations of the bark.—F. 0,

Small, pustulæform ; perithecia circinating, laterally compressed
; ostiola scarcely distinct, umbonate ; asci linear ; sporidia
broadly oblong, uniseptate, brown.—U««/. HooTc. Journ, no.

On oak. King’s Cliffe.
Scarcely a line broad, forming little pustules witb a black umbo ; peritbecia
circinating, closely packed, so as to present, when cut through, a triangle
witb one curved and two straight sides ; ostiola in general indistinct ;
asoi linear, containing 8 brown broadly oblong uniseptate sporidia, like
those of many Diplodioe.
Tbis curious species has been known to me for some years, but has never
been published in consequence of the doubt attached to its position,because
of its growing on living bark. Externally it is notunlike Sph. turgida. The
perithecia vary from 5-10, always laterally compressed, so that a section reminds
one of the carpels of an orange.—M.J.B.
Series 5. Pseudovalsa. Sporidia multiseptate, hyaline or
coloured.
2507. V a lsa d e tru sa . Fr. “ Barberry Valsa.”
Conical; stroma bright yellow, immersed in the wood, encircled
above with a conceptaculum; ostiola united, umbilicate;
sporidia biseriate, colourless ; endochrome quadripartite, elliptic.

On twigs of alder.
Forming minute pustules which pierce tbe cuticle by means of tbe flat
pallid disc, studded with black ostiola ; asoi linear ; sporidia four ('OOOg-'OOl

Fruit strongly resembling th a t of S.elongata.—B. & Br.
