MILDEW AND BRAND. 65 



to the records of science show him to be earnest 

 and vigorous still. 



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 us^ prompt us to dismiss these two-celled 

 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 Puccinia (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 woodrufi'_, bedstraw 

 (plate VIII. figs. 172^ 173)^ knotgrass^ ragwort_, and 

 other plants less common^ more locab or_, to the gene- 

 rality of the non-botanicab 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 by 

 no means minute^ but elongated and buUate ; the
