Strawberry Leaf-spot. 



[SEPT., 



salmon-colour; stem elongated whitish, with a sheath or 

 volva surrounding the base, 4 to 6 inches long, solid. 



This fungus is found on the ground, on heaps of decaying 

 leaves, &c, in summer and autumn. 



It bears a general superficial resemblance to the Sheathed 

 Agaric (Amanitopsis vaginata, Fig. 8), but is readily distin- 

 guished by the glutinous cap and the salmon-coloured gills. 



Verdigris Agaric (Stropkaria aeruginosa). (Fig. 24.) 



When in vigorous growth the entire fungus is of a clear 

 verdigris green colour. When growing in the open the cap 

 bleaches as it becomes old to a pale dingy yellow colour. The 

 cap is very glutinous, 2 to 3 inches across, stem scaly below 

 the ring; gills becoming purple. 



The most beautiful specimens occur in damp woods, 

 amongst grass and bracken in summer and autumn. When 

 growing in open places the bright colour soon disappears. 



Purple Agaric (Cortinarius purpurascens). (Fig. 25.) 



Cap expanded and more or less wavy, purplish-bay, very 

 glutinous, 4 to 5 inches across, flesh rather thick, clear blue; 

 gills broad, rusty-coloured when mature; stem with a bulb 

 at the base, solid, clear blue, about 3 inches long. 



This is found on the ground in pine woods, &c, in autumn, 

 Care must be taken to distinguish between this and Blewits 

 (Fig. 11), or the Amethyst Agaric (Fig. 13). In the Purple 

 Agaric the distinctly swollen or bulbous base of the stem and 

 the rusty gills are marked characters not present in the two 

 edible kinds mentioned. 



Both cultivated and wild strawberries are often severely 

 injured by a fungus called Sphcerella fragaricz, Tul., better 

 known in this country as Ramularia 

 Strawberry Tulasnei, Rab., a conidial form of the 



Leaf-Spot. Sphczrella, and for a long time the only 



known condition of the fungus. The 

 foliage is the part attacked, and the symptoms are unmis- 

 takable. Small reddish-brown spots appear on the leaves; 

 these often encroach on each other and form irregular patches. 

 By degrees the centre of each patch assumes an ashy-grey or 

 whitish colour, bounded by a reddish border, which becomes
