NEW BRITISH DISCOMYCETES. 
asci numerous, elongated, 8-spored ; paraphyses filiform ; sporidia 
very long, filiform, hyaline, continuous. 
Pocillum Boltonii, Phil., n.s. 
Minute, scattered, at first cylindrical, then becoming nearly tur- 
binato- truncate, glabrous, shining, horn-coloured, soft, watery, much 
contracted when dry ; hymenium plane or a little depressed ; asci 
broadly clavate ; sporidia 8, elongated, sub-cylindrical, obtuse at 
the ends, 40-50 x 8-4 p\ paraphyses filiform, thickened at the 
apices. 
On dead Equisetum , lying in water. Near Birmingham. (Col- 
lected by the late T. Bolton, after whom it is named, and com- 
municated by W. B. Grove.) 
Cups 100-200 /X broad, 800-400 p high. The sporidia, which 
are large for the size of the plant, are straight or a little bent, 
colourless, and furnished with several large vacuoles. They have a 
propensity to throw out long germ tubes while yet in the ascus. 
The excipulum is composed of elongated septate threads, but 
showing no colour as in the other species of the genus, P. Cesatii 
and P. Americanum. 
Lachnella callimoxpha (Karst). 
Cups gregarious, sessile or shortly stipitate, tomentose, somewhat 
plane, when dry spherical or hemispherico-contracted, hymenium 
yellow or orange-yellow ; asci subclavato-cylindrical ; sporidia 8, 
linear-fusiform, 6-8 guttm, or spuriously pluriseptate, straight, 
14-19 X 2-4 fi, paraphyses acerose. Lachnea callimorpha , Karst. 
8ymb., p. 250. Lachnum callimorphum , Karst. Myco. Fenn., 
p. 178. 
On dead leaves of Eriophorum angusti folium. Near Aberdeen. 
Spring. ( Jas . W. El. Trail.) 
Cups 800-500 p broad. Hairs short, not septate, colourless. Asci 
40-50 x 4 p. 
Qxnbxophila helotioides, Phil., n.s. 
Stipitate, solitary or casspitose, capitulate, pallid, glabrous, sub- 
gelatinous ; hymenium convex, margin thin, undulating ; stem 
cylindrical, a little flexuous ; asci cylindraceo-clavate ; sporidia 8, 
narrowly fusiform, straight, or slightly bent, 5-guttulate, 20-26 x 
2-3, 5 p, paraphyses filiform, hardly thickened at the apices. 
On dead stems of Equisetum in water. Autumn. Park Loch, 
near Aberdeen, 1886. ( C . B. Plowright.) 
Cup 1-2 lines broad, the whole plant 2-4 lines high, stem £ line 
thick. It differs from O. clavus in the sporidia. 
Berxnatea amaena (Tul). 
Cups sometimes csespitose, sometimes circinate, arising from the 
upper surface of a stroma which is occasionally black ; at first they 
are somewhat urceolate, then expanded and at length obconico- 
truncate ; disc orbicular, plane or convex, immarginate (not more 
than \ a line broad) ; when full grown they are fleshy, and very
