the power of one man to render of the first rank. The Ascomycetes 

 stand in great need of revision in our flora ; and the groups of 

 imperfect forms (Splicer op sideoz and Hyphomycetes) require discussion 

 from the sides alike of life-histories and of classification. A Myco- 

 logical Flora of the British Islands will be valuable in proportion as 

 it supplies information with regard to groups not recently treated 

 of by competent writers, that information being reliable and com- 

 plete up to the date of issue. 



It may be pointed out that the advance in the number of 

 recorded British species is even more striking than the above 

 extract from " Grevillea " shows. In the 2809 species in Cooke's 

 "Handbook" are included upwards of 100 species of Afyxogastres, 

 a group not included in the second enumeration just referred to.
