Davis — Parasitic Fungi in Wisconsin — I. 79 



Gnomoniella fimbriata (Pers.) Sacc. This was inserted in the 

 provisional list because of an immature specimen in the herbar- 

 ium of the University of Wisconsin which is perhaps of this 

 species. It was collected at Osceola by E. Sheldon in 1892. 



Phyllosticta destruens Desm. In writing the provisional list I 

 followed Ellis & Everhart (North American Phyllostictas, 40) in 

 referring to this species specimens on Prunus virginiana and al- 

 so on Amelanchier. 'The former has been described under the 

 name Phoma virginiana Ell. & Hals. ( Journ. My col. 4 :8. (1888) ) 

 the latter as Phyllosticta innumerabilis Pk. (Bull. Torr. Bot. Club. 

 36:336 (1909)). Specimens on Amelanchier were distributed 

 under the name Phyllosticta destructens Desm. in Fungi Colum- 

 bians continued 1447. I have seen no European specimens of 

 Ph. destruens Desm. which is said to ocour on Celtis as well as 

 Prunus and to have epiphyllous pycnidia, but I infer that Mr. 

 Ellis had good reason for using that name. Before the list was 

 printed I removed Amelanchier as a host of Phyllosticta 

 destruens Desm. with the intention of inserting Ph. innumerabilis 

 Pk. an intention which I failed to carry out, so that Amelanchier 

 as bearing the Phyllosticta appears only in the host index. Mor- 

 phologically I see no distinction between the fungi on the two 

 hosts. 



In the provisional list of parasitic fungi in Wisconsin Pa- 

 touillard is given as the author of the binominal Protomyces 

 andinus as is done in the Sylloge Fungorum. An examination 

 of Patouillard's paper however shows that it was published as 

 Protomyces andinus Lagh. sp. nov. Lagerheim, not Spegazzini, 

 collected the type material in Ecuador, not Chili. 



Phyllosticta mulgedii Davis, a name that was proposed in the 

 4th supplementary list (No. 709), was omitted from the provi- 

 sional list. The fungus has not been collected again and is prob- 



>jj ably one of the Plwmae that have been described as occurring on 



^i the leaves of Compositae. 



Phyllosticta desmodii Ell. & Evht. This was described (Journ. 

 ^ My col. 5: 146: 1889) from a single small collection in Walworth 

 Co. Much better material has been collected at Madison on Des- 

 modium canescens. The pycnidia are epiphyllous, brown, sub- 

 spherical, 125-160/x in diameter ; sporules oblong, often somewhat
