Davis—A Provisional List of Parasitic Fungi. 983 
and R. Carolina, by Arthur (Torreya 9, 26) Rust on foreign roses in 
Wisconsin as far as examined appears to be Ph. americanum Diet, or 
or Ph. disciflorum. 
Phyllosticta caricis (Fckl.) Sacc. The specimens which I have re¬ 
ferred to this spe'cies bear fusoidoblong sporules 10- 13 x 2%-3 /a. 
Phyllosticta cruenta d/.scincta (Davis). Specimens from Blue Mounds 
and Madison show sporules about 16 x 6/*. Ph. cruenta is referred to 
Macrophoma by Ferraris (Ann. Mycol. 10, 3, 288). This would make a 
generic separation of the two forms listed although the globose sporules 
of var. pallidior are equal in content to the longer and narrower 
sporules of var. discincta. 
Phyllosticta decidua E. & K. The form on horse radish which I 
have' referred to this species appears to be Ph. orhlcula E. & E. Some 
of the forms that I have referred to this species cause angular alutac- 
eous spots. Perhaps they should all be referred to Phyllosticta anceps 
Sacc. 
Protomyces andinus Pat. Judging from the description of this spec¬ 
ies, the type of which was collected in Chili by Spegazzini, P. gravidus 
is not distinct. It is doubtful however, if the form on Ambrosia with 
larger sporangia and usually forming larger galls is ccnspecific. 
Puccinia pygmaca Erikss. The specimens of rust on Calamagrostis 
that I have collected in Wisconsin and that have been referred to P. 
stAatula Pk. are in part of this species and in part P. coronata Corda. 
P. striaiula Pk. apparently does not occur in Wisconsin. 
Ramularia modesta Sacc. I have not seen authentic specimens of 
this species. The specimens which I have referred here were collected 
at Spooner. 
Ramularia nemopanthis C. & P. Specimens collected in Burnett Co. 
have branching hyphae and catenulate conidia 7-13 x 3-4/4. Appar¬ 
ently a vigorous state. 
Sclerotium rhizodes Awd. The list of hosts of this species, except¬ 
ing Calamagrostis canadensis , is taken from Research Bulletin No. 18, 
of the University of Wisconsin, Agricultural Experiment Station: A. 
B. Stout; June 1911. 
Septogloeum salicinum (Pk). Sacc. In this collection the sporules 
are mostly produced into long slender tips, sometimes almost bristle 
like. 
Sept or ia dimera Sacc. This is the fungus on Silene antirrhina that 
was referred to Septoria saponariae (DC.) in the supplementary list. 
It occurs on stems as well as leaves and the sporule's range mostly from 
20-40 x 3-4/4. usually with one septum. 
Septoria rumicis Ellis. This is antedated by S. rumicis Trail from 
which, judging from the description of the latter, it may not be dis> 
tinct. In that case Trail should be cited as the author. 
Septoria salicifoliae (Trel.) E. & E. On Spiraea tomentosa the fum 
gus is epiphyllous and the sporules are barns in acervuli and much
