Lembosia Agaves Earle. 



Our spores have at the fiill-ripe 

 stage (totally brown) an average size 

 of 17 — 20/^ X 7—9 /i (against 14- — 

 16^ X G — 7 fj. in Earl es diagnose). 

 The young asci are strongly thickened 

 in the apex.

 ascoma; c: Asci with paraphyses; d: Spores, 

 (a and 6: circ. ■'";i; c and d: '-^'li). 



Our fungus on leaves of Sac- 

 charum officinarum shows quite the 



same characteristic macroscopical aspect as the above species, what also 

 has been confirmed by comparing a type specimen of L. saccharicola 

 Henn., benevolently committed to us by the Botanical Museum of Berlin. 

 — Our asci are a little narrower (8 — 10« against 12 — 15«) and the 

 spores somewhat broader (5 — 5^2« against 4^«) as stated in Hennings' 

 description of the species; unfortunately the type specimen examined did 

 not contain any asci. 



A type specimen of SphaeruUna Sacchari P. Henn., likewise sent 

 to us from Berlin, is thoroughly identic with the above species as to the
