'riie ibrms here included under M. Alni have lieen assijrned by 

 dilVercnt authors to various species, distinuuished, for the most part, l)v 

 the number of the asci and sporidia. Tn all of these foiius, the size of 

 the perithocia, even when standinjr side by side on the same leaf, is 

 (juite variable, and, as a consequence, the numl)er anil shajie of the asci 

 they contain vary e(jually widely. Very small perithecia contain only 

 a few (2-4) suborbicular asci, while lar^'er ones contain a ureater nuiii- 

 l)er, which, owing to lateral crowding, are narrower and longer. The 

 sporidia are by no means con.^tant in number, even in asci from the 

 same perithecium. It is manifestly impossible to maintain specific dis-
