This species has been much confused; all those specimens 
which I have seen on leaves of Vinca belong to Ceuthospora 
Feuricht Bubak, and many of those on Euonymus to Ceuthospora 
Euonymi Grove. It is nowhere common, but is recorded also 
on the Continent on leaves of Acer, Crataegus, Quercus, Smilax, 
ete. It is quite possible that all these are only leaf-forms of those 
species of Cytospora which occur on the branches and twigs : 
é.g. when on leaves of Huonymus it is possibly merely a form of 
Cytospora Euonymi (q.v v.). The variable size of the spores given 
in books, “up to 12 p,” is probably a result of this confusion, 
for on Euonymus leaves they measure only 4-6 x.
