Davis — A Provisional List of Parasitic Fungi. . 9So 



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 fusoid-oblong sporules 10- 13 x 2^-3/u. 



Phyllosticta cruenta dt.scincta (Davis). Specimens from Blue Mounds 

 and Madison show sporules about 16 x 6/x. Ph. cruenta is referred to 

 Macrophoma by Ferraris (Ann. Mycol. 10, S, 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. orbicula 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. gravidas 

 is not distinct. It is doubtful however, if the form on Ambrosia with 

 larger sporangia and usually forming larger galls is conspecific. 



Puccinia pygmaea Erikss. The specimens of rust on Calamagroatis 

 that I have collected in Wisconsin and that have been referred to P. 

 stttatula 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^. 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. 



Septoria 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 sporules range mostly from 

 20-40 x 3-4/t. 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 fun- 

 gus is epiphyllous and the sporules are boras in acervuli and much
