NEW OR CRITICAL BRITISH FUNGI. 
121 
Sarcoscypha tenuispoxa, Cfce. # Mass. 
Cups stipitate, at first clavate, often distorted and confluent, 
reaching 1 inch in height and 1 inch diameter, fleshy, soft, ex- 
ternally white, clad on the stem especially with short white woolly 
hairs, which diminish to the almost naked margin. Stem thick, 
variable, scarcely so long as the cup, into which it is gradually 
expanded. Disc plane, seldom concave, whitish, becoming dusky, 
scarcely marginate ; substance of the cup thick and fleshy. Asci 
cylindrical, spores very narrowly elliptical, rounded at the ends, 
binucleate, 16-20 x 4-5 p, paraphyses slender, scarcely thickened 
above, externally granular. 
On sticks and dead leaves. Scarboro’ (G. M.). Halifax 
(Crossland). 
Remarkable for the scarcely depressed disc, and especially for 
the very narrow spores, which are comparable to those of no 
other large Peziza. 
Txichopeziza caxinata, CJce. fy Mass. 
Sessile, ^ m.m. broad, gregarious, snow-white, at first globose 
with a narrow mouth, at length more expanded, externally deeply 
and longitudinally channelled, so as to present from 5 to 7 distinct 
acute ridges or keels, clad with short white tomentose down, without 
septa, asci sessile, clavate, spores biseriate, subfusiform, nucleate, 
12-16 X 3 p. 
On fern stems. Halifax (Crossland). 
Allied to Trichopeziza hexagona , Fckl., but with much larger 
sporidia. 
BIBLIOGRAPHY. 
Rust or Mildew on Wheat Plants , is the title of a small 
pamphlet issued by the Board of Agriculture, and contains a con- 
siderable amount of information on the subject. The points of 
greatest interest are probably the following : — 
Puccinia ruhigo vera is reproduced year after year in frightful 
quantities by the uredospores only. 
Puccinia graminis is far more destructive to corn crops in 
countries where the Berberidace^ are not indigenous than in 
Europe ; hence this species, like P. ruhigo vera, must either be 
able to reproduce itself year after year from the uredospores only, 
or the aecidiospore condition is developed on some plant not 
belonging to the Berheridaceae. The first alternative is most 
probable, but not yet definitely proved. 
Spraying with a fungicide has, on the whole, proved beneficial. 
Rust resisting varieties of wheat are characterized by a thick 
cuticle, tough leaves, and copious bloom on the stem of the 
growing plant.
