NEW BRITISH FUNGI. 
3 
Russula (Fragiles) fingibilis, Britz. Hym. Sudb. iv,, /. 32 . 
Pileus yellow, convex, then plane or depressed, viscid, darker in 
the centre (about 2 in. diam.), thin towards the margin, but not 
striate. Stem equal, soft, white, spongy, at length hollow (2 in. 
long, J in. thick), flesh white, mild, inodorous. Gills rather 
unequal, attenuated behind, somewhat crowded, thin, white. Spores 
nearly globose, 8-10 /x. 
Under trees. Kew, July, 1882. 
As far as it is possible to identify any of Britzelmayr’s species 
this seems to accord, taking into account the additions we have 
made to the diagnosis. 
Hypocrea moriformis, Cke. Mass. 
Fleshy, hemispherical (1 mm. diam.), scattered, pallid, at length 
black ; perithecia convex, minute, rather prominent, pierced with a 
pore ; asci cylindrical, sporidia uniseptate, then dividing into cubi- 
cally globose frustules, olive, smooth (5-6 /x). 
On rotten wood. Carlisle. (Dr. Carlyle) . 
Perithecia distinctly indicated, resembling a miniature mul- 
berry. 
Nectxia pallidula, Cooke. 
Perithecia caespitose, globose, minute (i mm.), smooth, pale 
ochre, bursting through the cuticle in irregular tufts, sometimes of 
one or two, sometimes 12 to 20 perithecia, effused when growing 
on naked wood. Asci clavate-cylindrical, sporidia for the most 
part uniseriate, subfusiform, uniseptate, hyaline (12x3 p). 
On beech bark and wood. Carlisle. (Dr. Carlyle). 
Mucor lateritius, Cke. fy Mass. 
Mycelium forming a continuous dense, dry, bright-brown felt, 
spreading over the tuber. Fertile hyphas erect, simple or furcate ; 
capitulum globose, sporidia subglobose (12 x 9-10 /*), pale brick- 
red, smooth. 
On putrid potatoes. Kew. 
Trichosporium umbrinum, Link. 
Threads branched, bay-brown, forming a dense, long, and broadly 
effused interwoven stratum ; conidia globose, smooth, brown (12- 
14 fx diam.). 
Running over plant pots, &c. (“ Gardeners’ Chronicle.”) 
(Edocephalum sulfureum, Cke. Sf Mass. 
Tufts hemispherical or confluent, sulphur-coloured. Threads 
septate, dichotomous, globosely capitulate at the apex, papillate, 
conidia globose, hyaline (3-5 /x diam.). Epispore smooth. 
On rope. Herbarium grounds, Kew. 
Melanconium xusci, Cke. <$• Mass. 
Pustules scattered, orbicular, erumpent, covered by the lacerated 
brown cuticle. Conidia elliptical, continuous, sooty-olive (12 x 
7-8 M ). 
On phyllodes of Ruscus aculeatus. Kew. 
This cannot be a form of Sphceropsis rusci , for there is no peri- 
thecium, and the pustules are scattered and solitary.
