40 Rev. M. J. Berkeley & Mr.C. E. Broome on British Fungi. 
On very rotten wood. Langridge, April 27, 1874, C. E. B. 
Walls composed of large cells; sporidia ‘0015 inch long, 
0007 wide. 
On the same wood with this species, and probably its stylo- 
sporous state, is a minute Spheronema, flask-shaped, with a 
long slender neck and minute globose spores. 
Puate I, fig. 9. a. plant, m situ; b, tissue of perithecia; c. ascus; 
d, sporidia. All more or less highly magnified. 
*Venturia alchemille, B. & Br.  Peritheciis minutis in 
maculas parvas stellatas congestis ; ascis brevibus lanceolatis ; 
sporidiis fusiformibus uniseptatis. 
On leaves of Alchemilla, on which it appears in the form of 
little jet-black stellate spots. New Pitsligo, Rev. J. Fergus- 
son, Dec. 31, 1873. 
Sporidia shortly fusiform, narrow, ‘0005 inch long, uni- 
septate. 
This is Asteroma, Grev., Stigmatea, Cooke; apparently 
owing its stellate appearance to the perithecia following the 
veins of the leaves. Fuckel’s specimens have the character- 
istic short hairs. 
* Dothidea betulina, Fr. 
Pyenidia of this species have been sent from the Rev. J. 
Stevenson, and very closely resemble those of D. udm, which 
have also been received from Scotland, and are equally refer- 
able to the genus Piggotia. 
1494. Hysterium arundinaceum, Schr., var. gramineum ; 
H. culmigenum, var. 8, Fr. Syst. v. 2. p. 591; Moug. & 
Nest. 
On leaves of grass. Torres, Rev. J. Keith. 
This agrees exactly with H. arundinaceum, and is the plant 
of Mougeot and Nestler, and not with H. culmigenum, to which 
the specimen in Cooke’s ‘ Exsiccata’ belongs. 
1495. Mucor pruinosus, B. & Br. Pusillus, niveus; vesi- 
culis globosis, reticulatis ; sporis irregularibus. 
Covering with a thin white stratum the soil of garden-pots, 
the plants in which in consequence perished. Sibbertoft, 
Nov. 1873. Spores ‘0007-0012 inch long. Some decayed 
seeds of kidney-beans had been in the soil, and probably were 
the nidus of the mould. 
1496. Thamnidium Van Tieghemi, B. & Br. | T. elegans, 
Ann. d. Sc. Nat. sér. 5. v. xvii. p. 321. 
On cabbage-stalks. 
Clearly quite different from 7’. elegans (Ascophora elegans, 
Cd.), as a comparison of Van Tieghem’s figure and Corda’s
