BriiisJi Fungi, 



great work/ comj^letely upsets all previous arrange- 

 ments, which familiarity rather than conviction has 

 endeared us to ; nevertheless, every attempt, from that 

 of Persoon up to the present day, has done something 

 towards the present state of things, and it cannot be 

 considered that finality has been attained in the pre- 

 sent arrangement, yet remembering that the basis of 

 the scheme rests on the only known sure foundation — 

 life-history of forms — mostly worked out by the 

 author himself, and in such numbers as to give a good 

 opportunity of distinguishing between important and 

 unimportant characters, is suflScient to commend the 

 result to all unprejudiced minds (pp. 72, 73). 



In a systematic work the Hj/phomycetes, Melan- 

 coniese, and Splimro'psidepe must find a place, conse- 

 quently the following modification of Bref eld's classi- 

 fication will be adopted in the present work.
