34 Rey. M.J. Berkeley & Mr.C. E. Broome on British Fungi. 
Looks at first sight like a little Sphinctrina. So minute that 
it is quite invisible to the naked eye. 
1454. Peronospora calotheca, De By. 
On Galium aparine. Forden, April, Rev. E. Vyse. 
1455. P. interstitialis, B. & Br. Maculis luteis, a venis 
limitatis ; floccis brevissimis, flexuosis; sporisovatis terminatis. 
On leaves of primrose. Glamis, Rey. J. Stevenson; Men- 
muir, Rev. M. Anderson. 
Spots hypophyllous, yellow, confined to the interstices of 
the veins, or very rarely extending slightly beyond them ; 
spores often seated obliquely, ‘0006-0007 inch long. Alhed 
to P. obliqua, Cooke. 
1456. P.rufibasis, B. & Br. Maculis epiphyllis nitidis fulvis; 
hypophyllis pallidis ; sporophoris linearibus ;_ sporis obovatis 
elongatisve variis, oblique sitis, brevissime pedicellatis. 
On leaves of Myrica gale. Glamis, Rev. J. Stevenson. 
The spots on the upper surface of the leaves are very con- 
spicuous. Closely allied to P. obliqua and the last. Spores 
very variable in length. 
1457. Penicillium megalosporum, B. & Br. Niveum, breve ; 
floccis fasciculatis ; sporis globosis elongatisque levibus. 
In an old chicken-coop. Menmuir, Rev. M. Anderson. 
Spores *0005-"001 inch in diameter, or equally variable: when 
oblong. 
* Fusarium minutulum, Cd. 
On rotten boards. St. Catherine’s, Bath, Jan. 5, 1874. 
Spores *0002 inch long. 
1458. Cylindrosporium rhabdospora, B. & Br. Maculis 
amphigenis, orbicularibus, brunneis; sporis albis radiantibus, 
oblongis, triseptatis, obtusis, utrinque paululum excavatis. 
On leaves of Plantago. Glamis, Rev. J. Stevenson. 
Spores forming little radiating fascicles, oblong, slightly 
hollowed out at the sides, ‘0008-002 inch or more long. 
Sometimes a second is developed at the tip of the first. 
*C. ficarie, B. 
Common on leaves of Ranunculus ficaria. 
This is placed by Cooke in Glwosporium ; but the spores are 
not contained in a perithecium. Cylindrosporium concentricum, 
Grey., is, on the contrary, a true Glwosportum, and is not un- 
common on cabbage-leaves. 
1459. OC. nivewm, B. & Br. Maculis fusco marginatis ; 
sporis niveis, oblongis, uniseptatis, breviter pedicellatis. 
On Caltha palustris. New Pitsligo, Rev. J. Fergusson. 
Spots numerous, crowded, one or two lines across, often 
confluent ; spores oblong, uniseptate, when fully grown about 
‘002 inch long.
