for determination, and he, following Graillard,* named the fungus Meliola 
manca. In a recent publication f F. L. Stevens writes as follows : 
" In ' Le G-enre Meliola,' G-aillard writes under Meliola manca the three 
species M. manca, M. sanguinea, and M. imiggarii, giving a new description 
of M. manca. This new description mentions larvaeform perithecial appen- 
dages. The original description of M. manca by Ellis and Martin mentions 
no such appendages, but does specifically state that there are no perithecial 
appendages. My own material of the two collections is ample. I have 
studied it carefully, also a specimen of the Heller collection, and a specimen 
Collected by Martin and distributed by Ellis as IST.A.F. No 1292, all of these 
upon the same host (Myrica cerifera L.). These specimens all agree perfectly, 
and agree with the original description. They do not have larvaeform 
perithecial appendages, and therefore do not conform with the description as 
given by Gaillard.

" The specimens of Meliola which have been found on Buhus agree well 
with the description of Meliola puiggarii. They have abundant larvaeform 
appendages, and cannot be placed under M. manca. Moreover, both the 
general characters of the mycelium and the capitate hyphopodia separate 
the forms on Buhus from those on Myrica, the hyphopodia on Buhus being 
much larger and more irregular in shape. I am forced, therefore, to regard 
the description given by G-aillard for M. manca as erroneous, and that of 
Ellis and Martin as correct, and to recognise M. puiggarii on Buhus as an 
entirely different species." 
In view of the evidence thus clearly set forth, and after examining 
specimens of both species kindly sent me by Mr. Stevens, I am driven to 
conclude that the South African specimens on Bosaceae which have abundant 
larvaeform perithecial appendages should be named M. puiggarii. The South 
African specimens agree with the Porto Rico specimens of M. puiggarii, the 
only difference being that the larvaeform perithecial appendages are, if any-
