NEW BRITISH FUNGI. 
7 
mm.); paraphyses filiforai, slender. Stylospores in the same hyme- 
nium, elongated, cylindrical, with 5-8 nuclei, curved, on short 
sporophores seated amongst the asci ('03-'05 x '005 mm.). 
On inner bark of Cistus lauri folius. Kew. 
Valsa (Cxyptospoxa), Betulae, Tul. Sacc. Syll. 4124. 
Pustules orbicular, immersed ; perithecia 8-10, circulating, 
globose ; disc scarcely emergent, conical, ostiola punctiform, rather 
prominent. Asci cylindrical-clavate, attenuated below. Sporidia 
linear, obtuse at the ends, arcuate, continuous, hyaline (*035-*038 
X '0035-‘005 mm.). 
On branches of Betula. Kew pleasure grounds. Near Bristol. 
((7. BucJcnall). Sphaeriacei Brittanici. ( Plowright .) 
Although found in Britain for some years, the description 
appears to have been omitted. 
Valsa (Chorostate) Robexgeana, Desm. Sacc. Syll. 2388. 
Corticolous, immersed, minute. Perithecia 6-15, covered by 
the adnate epidermis, crowded in an irregular circle, black, at first 
globose, then collapsing and concave. Ostiola convergent, cylin- 
drical, erumpent. Asci somewhat fusiform, sporidia eight, bise- 
riate, somewhat elliptical, uniseptate or biguttulate, hyaline (’015 
X *005 mm.). 
On StapJiylea pennata. Pleasure grounds, Kew. 
What appears to be another species has been met with but once, 
with fusiform, acute, narrow, quadri-nucleate sporidia, about *014 
X '003 mm., which can hardly be any form of the present. 
Diapoxthe vixidarii, Sacc. Syll. 2568. 
Stroma broadly effused, immersed in the bark or wood of the 
branches, circumscribed by a flexuous line. Perithecia rather 
large, globose, then depressed ; neck very short; ostiola rather thick 
and obtuse. Asci somewhat fusiform. Sporidia ovate-fusiform 
(•015--016 x '005 mm.), uniseptate, constricted, obtuse at the ends, 
with 4 nuclei, hyaline. 
On slender twigs of Prunus lauro -cerasus. Kew. 
Sphaexia (Didyxnella) sphingiophoxa, Oadem. Diaporthe sphin- 
giophora, Sacc. Syll. 2414. 
Perithecia scattered, nestling beneath the epidermis, at length 
erumpent, furnished with a short neck perforated with a round pore. 
Asci oblong, with eight spores. Sporidia biseriate, oblong, obtuse 
at the ends, straight or slightly curved, uniseptate, hyaline ('017 
X '005 mm.). 
On small twigs of Cornus alba. Kew. 
This species and Sphceria salicella, Fr., cannot with any reason 
be included in Valsa or Diaporthe . 
Hypocxea dacxymycella Cke & PI. Grev. xii. 100. 
By some error this species was described again by Mr. Plow- 
right (Grev. xiii. p. 79), under the name of Hypocrea viscidula.
