NEW OR CRITICAL BRITISH FUNGI. 
where the specimens appeared ; nevertheless, it is not usual for 
members of the Gastromycetes to come up from spores, not at 
least when the spores are sown with the hope of producing the 
fungus. Its discovery in other parts of Great Britain will be 
necessary, we presume, to remove it from the list of “ probably 
introduced species,” which it will at present figure in. 
Neottiella microspora, C. $ Mass. 
Ceespitose, cups fleshy, subsessile, regular or deformed by mutual • 
pressure, subglobose, then expanded, immersed at first nearly to 
the margin, externally whitish, clad with minute, flexuous, septate, 
hyaline hairs ; disc concave, then plane, greenish sulphur colour. 
Asci cylindrical, spores eight, uniseriate, elliptical, smooth, 
hyaline, 7 x /a; paraphyses filiform. 
On a dunghill. Scarborough. 
Cups 2 mm. to 1 cm. broad. External liairs 50 p. long, 3-5 [x 
thick. Base of the cups a little obconical, immersed. 
Orbilia flexuosa, Crossl. 
Scattered, sessile, 1-2 mm. broad, disc at length plane, pale, then 
dark reddish amber, similarly coloured externally ; margin raised, 
usually lobed and wavy, composed of narrowly clavate, closely 
septate hyphse ; asci cylindrical, narrowed towards the base, spores 
eight, uniseriate, elliptic-fusiform, usually biguttulate, smooth, 
colourless, 8-10 x 4-5 /x ; paraphyses numerous, filiform. 
On decaying bark. Horny when dry ; margin sometimes even 
and almost plane. 
Lightcliffe, near Halifax. (Crossland, No. 53.) 
Oxbilia inflatula, Karsten = Calloria inflatula {Karst.), Phill ., Brit. 
Disc., p. 335. 
This species has been found by Mr. Rea in abundance on the 
inside of birch bark in Wyre Forest. Owing to a slip, the 
measurement of the spores in Brit. Disc, is given as 4-7 X 5 fx, 
instead of 4-7 x ‘5 fx. 
Fatinella macxospora, Mass. 
Scattered, 1-1*5 mm. across, sessile and broadly applanate, 
margin slightly raised at first, often becoming quite plane with age, 
blackish, somewhat coriaceous ; marginal cells erect, densely 
packed, slightly clavate, closely septate ; asci cylindrical, narrowed 
below the sporiferous portion into an oblique pedicel, spores eight, 
uniseriate, broadly elliptical, ends rather acute, usually 1-guttulate, 
colourless, smooth, 11-12 x 6-7 /x ; paraphyses numerous, cylin- 
drical, septate, about 1-5 /x thick. 
On rotten wood. Halifax. (Crossland, No. 20.) 
Vexticillium Rexianum, Sacc. 
Forming a pure white, minutely velvety layer ; sterile hyphas 
creeping, branched, septate, much interwoven, 4-5 /x diameter ; 
fertile hyphce numerous, erect, straight ; 80-125 X 3-4 /x, septate, 
the upper two-thirds furnished at intervals with spreading 
branches, opposite or rarely in threes, tips of branches with 1-3
