This makes a total of fifty-two species, and is the second

 vSwansca, in i(ji5, forty-seven species; Shrewsbury in 1916 

 and Wrexham in 1910 each gave us forty-four species ; Hasle-

 directed to the Flowering Plants. The striking beauty of so 

 many of them, their wonderful diversity in form and colour 

 and fragrance, and the manifold ways in which they could be 

 made use of for the advantage of man, early arrested the eye, 

 and stimulated curiosity, and led to their closer study. But 

 Fungi had a hard fight to be included in the awakened interest 

 in trees and shrubs and herbs, and it is only in comparatively 

 recent times that they have won their way to adequate recog-

 Treatise on Materia Medica which was for many centuries 

 received as a standard authority, and in which Fungi are not
