conglobate in versiform glomerules, compressedly angular, brown, 
semi-opaque (10u diam.). Sacc. Syll. IV., No. 2442. 
On fading and dead blotches on leaves of apple. Sci. Com., R.HS. 
Scarcely to be deemed a parasite, as evidently it is not the cause 
of the withering of the leaves. Compared with authentic specimens 
and found to be the same. Orriginally discovered on leaves of Cornus, 
CEdomyces leproides Trabut. Sacc. Syll. XI., p. 234. 
Forming large nodulose, fleshy tumours on the upper part of the 
root of beet and on young potato tubers. Spores globose depressed, 
umber (40-50 X 30), acrogenous ; mycelium inflated into a vesicle 
below the spores; spores produced in masses within spherical cysts 
in the substance of the tumours. 
On beet root and potato tubers. Destructive. 
Hitherto the tumours have been found in Britain on beet root, but 
without spores. Upon potatoes for the past two years the disease 
has been but too common, fully producing spores, and laying waste 
extensive crops. Dr. Magnus has determined the fungus of the 
potato tumour to be identical with that of the beet root, although 
it has been described under a different name as Chrysophlyctis endo- 
biotica (Schilbersky).*
