372 E. S. SALMON ON NEW OR RARE BRITISH FUNGI. 



Hah. — New Pitsligo, Scotland, on Vicia sylvatica (in Berkeley's 

 Herbarium at Kew). 



The record of M. Bdumleri as a British plant rests on the 

 single specimen, above mentioned, in Berkeley's Herbarium at 

 Kew. This specimen was named " Erysiphe communis " {E. 

 Polygoni) by Berkeley, and to some forms of that species 

 M. Bdumleri bears a close resemblance. The present plant, 

 however, may always be recognised, when mature, by the definite 

 apical branching of the appendages (see Figs. 1 and 2). In 

 E. Polygoni, although the appendages often become much 

 branched, the branching is vague and never strictly apical. 

 M. Bdumleri is very closely related to M. Astragali (DC.) Trev. — 

 a species found in Britain on Astragalus Glycyphyllos — and 

 scarcely differs except in the more branched apex of the 

 appendages. 



The distribution of M. Bdumleri is as follows : — Germany, 

 Austria-Hungary, Italy, and Russia. Its host-plants are Vicia 

 cassuhica and V. sylvatica; and search for the fungus on the- 

 latter plant should be made in England.
