MILDEW AND BEAND. 65 



science prove bim to have been earnest and vigo- 

 rous up to the 'day of his death. 



We have by no means exhausted the catalogue 

 of Fungi belonging to this genus found in Britain, 

 nor even those commonly to be met with ; but the 

 fear of prolixity, and the desire to introduce a 

 description of other forms into the space still re- 

 maining to uSj prompt us to dismiss these two-ceUed 

 brands with but a brief allusion to such as we cannot 

 describe. Box-leaves are the habitat of one species, 

 and those of the periwinkle (plate VI. fig. 132) of 

 another. One vegetates freely on the leaves of violets 

 through the months of July and August, and another 

 less frequently on the enchanter's nightshade. Se- 

 veral species of willow-herb (Epilobium) are attacked 

 by one Fuccinia (plate IV. figs. 78, 79), and a single 

 species by another. Plum-tree leaves, bean-leaves, 

 primrose leaves, -and the half-dead stems of aspa- 

 ragus, have their separate and distinct species, and 

 others less commonly attack the woodruff, bedstraw 

 (plate VIII. figs. 172, 173), knotgrass, ragwort, and 

 other plants less common, more local, or, to the gene- 

 rality of the non-botanical, but imperfectly known. 



We have found, not uncommonly in the autumn, 

 the scattered pustules of a brand on the stems and 

 leaves of the goat's-beard, occupying the places 

 which were scarred with the remains of cluster-cups 

 that had flourished on the same spots a month or two 

 previously (plate IV. fig. 76) . The pustules are bj 

 no means minute, but elongated and buUate ; the
