Gloeosporium rihis (Lib.) Mont. & Desm. As it occurs in Wis¬ 
consin this usually has the characters of the forma ribis nigri 
americana Sacc. The sporules sometimes reach 30/*, in length. 
Gloeosporium tremuloides Ell. & Evht. 2nd suppl. list no. 526 
was omitted from the provisional list because of the belief that 
the species was founded on imperfectly developed material of 
Marssonina castagnei (D. & M.) Magn. which occurs in atypical 
forms in Wisconsin. Oudemans proposed the variety monili- 
ferae in which the acervuli are amphigenous although more abun¬ 
dant above. In Wisconsin they are often hypophyllous only and 
the sporules are often but 12-15/*, long. Marssonina brunnea (E. 
& E.) has been omitted, being considered, perhaps erroneously, 
a form of M. castagnei. 
Ramularia plantaginis Ell. & Mart. In the description of this 
species the spots are said to be minute. Specimens on Plantago 
Rugelii collected at Madison in September have spots up to 3 cm. 
in diameter. Conidia appear also on the ealyces. 
Ramularia alismatis Fautrey. This was reported in the third 
supplementary list under the name As cocky t a alismatis (Oud.) 
Trail. Dr. R. A. Harper has kindly compared Wisconsin ma¬ 
terial with the type of Ascockyta alismatis Ell. & Evht. in the 
Ellis herbarium and finds them to be the same. The very short 
undifferentiated conidia-bearing hyphae makes this an atypical 
Ramularia. It is not unlikely that Septoria alismatis Oud. is of 
the same character. The spots usually have a slight eminence 
in the center as if a pycnidium lay beneath. (See Diedicke, 
Ann. Mycol. 10:479). 
Ramularia uredinis (Yoss) Sacc. This is the fungus recorded 
in the supplementary and 3rd suppl. lists no. 330 under the name 
Fusarium uredinum E. & E. The tufts are sometimes pink or 
even testaceous. My measurements of the conidia, which are in 
branched chains, are from 7-17x3-4^. 
Ustilago osmundae Pk. This has been collected on Osmunda 
regalis in Washburn and Burnett counties. I have not been able 
to follow the author of the species in his reference of it to My- 
cosyrinx. (New York State Museum; Report of the Botanist 
1911, p. 43). When the fungus is present each frond arising 
from the rhizome bears the smut or else is sterile.
