Laestadia Ailanthi, Grove sp. n. 



Perithecia subdense sparsa, membranacea, lentiformia, atra, 

 ca. 150 fx diam., tecta, dein erunipentia. Asci clavulati, GO x

In company with the Colletotrichum. The similarity of the 

 spores of these two species is very great, only those of the 

 Laestadia are a little shorter, broader, and more fusoid in shape. 

 To the naked eye the size and general appearance of the two 

 fungi are also very similar, and they are mingled indiscriminately 

 on the twigs. 



. (3). The Diplodia referred to is Diplodia ailanthiria, Spe£. 

 (Sacc. Syll. iii. 332) in all essential respects, but would be 

 better described as a non-caespitose form of 





Botryodiplodta Ailanthi, Sacc. (var. simplex, m.).
