NEW AND RARE BRITISH FUNGI. 
Spheres, exclusive of flocci, '2 mm. diameter. This species differs 
from other British species in the flocci not radiating from the centre 
of the spore-mass, but arising from a beautiful latticed frame- 
work surrounding the spore-mass like a spherical cage. It is 
near M. ochracea , B. & B., but it has no deflexed branches on the 
flocci, and the spores (conidia) are elliptical. 
250. Tubercularia vinosa, Sacc. Mycol. Venet. No. 1089. Michel, p. 
262. Fungi Ital. No. 963. 
Very similar to T. persicince , Ditmar, but differing in the 
cluster being larger and vinous. Conidia subglobose or ovoid, 11- 
12 x 10 (not 7 to 8 mk. in diameter), basidia shorter, thicker, and 
simple. 
On Rcestelia lacerata. Downham, July, 1884. On sEcidium 
asperifolii. Castle Bising, Oct., 1884. 
251. Uzocystis Fischeri, Kornicke. Hedwigia , 1877, p. 34. 
Uredo Agropyri, Preuss. Urocystis Agropyri, F. v. W. 
Spore-balls with 1 or 2, more rarely 3, central spores, 20 to 45 
mk. in diameter. Central spores intersecting, somewhat larger 
than those of Ur. occulta , generally 17-19 mk. Accessory spores 
firmly attached in large numbers, quite encircling the central spores, 
almost as darkly coloured. 
On the leaves of Carex glauca. Mr. Soppett, Nov., 1884. 
252. Ustilago hypogaea, Tul. Fungi Hypogcei, 1862, p. 196. 
Spores rounded or rounded-polygonal, 20 to 24 mk. long, by 14- 
20 wide ; dark brown, scarcely transparent ; contents very olea- 
ginous. 
Forming a compact mass around the root-stock of Linaria 
spuria , intersected with white fibres. 
Freshwater, Isle of Wight. Dr. John Lowe, 1869. 
253. Entyloma bicolor, Zopf. 
Spores spherical, elliptical or polygonal, of very various sizes, 
(about 12-17 mk. in diameter, to 23 mk. long). Epispore gela- 
tinous, of variable thickness, at first colourless, afterwards brown. 
Conidia on simple or branched conidiophores, which emerge through 
the stomata on the under surface of the leaves in clusters. Cylin- 
drical, curved, smaller at the base, rounded above, simple or septate, 
colourless, 10 to 22 long by 3 mk. wide. 
On the leaves of Papaver rhceas. North Wootton. July, 1882. 
254. Uromyces poa, Rbh. 
I. ^Ecidiopores , sEcidium Ranunculi repentis , and Jicarice. 
II. Uredospores. Sori rounded, elliptical, lanceolate or linear, 
long, covered by the epidermis, which at length splits longitudi- 
nally. Spores roundish, elliptical or ovate, finely echinulate, orange- 
yellow, 16 to 25 mk. in diameter, without paraphyses. 
III. Teleutospores. Sori small, punctiform, or rather elongate, 
covered by the- epidermis. Spores rather long, thin, pedicels very 
varying and irregularly formed, mostly elliptical or ovate, brown
