NEW AND RARE BRITISH FUNGI. 
approaches very closely to Fuckel’s Quaternaria NitschJcii, which 
Saccardo considers a corticolous state of Melogramma gastrinum. 
217. Valsa (Valsella) clypeata, Fckl, 
Conceptacles shield-like, oblong, 1*5 mm. long by 1 mm. wide, 
black, immersed in the substance of the bark, olivaceous within ; 
disc rounded or oval, projecting through a fissure in the epider- 
minis, whitish ; perithecia 4-8, crowded, globose, minute black ; 
ostiola punctiform, black ; asci sessile, oblong, polyporous, *052 x 
*007 ; sporidia cylindrical, obtuse at both ends, slightly curved, 
simple, •006--007 mm. long by *0015 mm. wide.

On dead bramble stems. Forres. Rev. James Keith. April, 1880. 
218. Cucurbitaxia lauxo-cexasi, Ph. Sf PI. 
Perithecia erumpent, 1 to 4 in a group, globose, smooth, small ; 
ostiola inconspicuous ; asci cylindrical, •12- , 125 X ’02 mm. ; 
sporidia uniseriate, dark brown, oblong, ovate, slightly constricted 
about the middle, muriform, -02--025 X *012 mm. 
On cherry laurel. Forres. Rev. J. Keith. May, 1880. 
This species comes near Fuckel’s C. coryli (Nach. I., p. 20), as 
far as the size of the sporidia, but differs in other characters. 
The sporidia have often seven primary transverse septa — four in 
upper half of the sporidia and three in the lower.

219. XlfXassaxia tiliae, Ph. Sc PI. 
Perithecia subcuticular, globose, then depressed, black ; ostiola 
minute, just piercing the epidermis ; asci subcylindrical ; sporidia 
eight, hyaline involved in gelatine, triseptate, constricted at the 
septa, quadrinucleate, *04--06 mm. long by *01 mm. wide. 
On lime twigs. Forres. Rev. J. Keith. May, 1880. 
This species comes very near Massaria eburnoides, Sacc., but the 
sporidia are twice the size of Saccardo’s plant.

220. Soxdaxia pleiospoxa, Winter. 
Perithecia scattered, semi-immersed, globose ; neck conical ; 
apex curved, thick, obtuse, attenuated almost to the length of the 
perithecia, brownish-black, covered by short thick black hairs, 
about *38-’42 mm. in diameter ; asci large, elongate, ventricose, 
16-64 sporous, *36 mm. x ’08- *12 mm. ; paraphyses tubular 
branched, shorter than the asci ; sporidia ovate, opaque, black- 
brown, truncate at both ends, and appendiculate, terminal append- 
age, hyaline, curved as long as the sporidium, inferior append- 
age, straight, twice or thrice the length of the sporidium ; sporidia 
without the appendage, *024-’033 X ’016--019 mm.
