APPENDIX. 
Cercospo'ra rubigo Cke. & Hark (?) 
Of the fungus doubtfully referred to this species the following notes 
were made: Spots angular-suborbicular, limited by the veins, reddish 
brown, 5-8 mm. in diameter; hyphae hypophyllous, fuligineous, assur- 
gent to ere'ct, often arising as branches from a superficial creeping 
mycelium, sometimes branched, usually crooked and denticulate or 
nodulose 25—GO x 2fjc; conidia hyaline, attenuate from a point about 
10 n above the base where the diameter of the conidium is greatest, 
straight or more often somewhat curved, pluriguttulate, 50-125 x 3-4/t. 
On Spiraea salicifolia, Spooner, Wis., July 20th, 1911. 
Cylindrosporium thalictri (E. & E.) {C. ranunculi (Bon.) Sacc. forma 
is borne on suborbicular spots which are first red on the upper surface 
becoming pale olive and finally sooty with the developing hyphae and 
conidia. 
Cylindrosporium thalictri (E. & E.) C. ranunculi (Bon.) Sacc. forma 
thalictri E. & E. Journ. Mycol. 8, 130 (1887). This seems to be dis- 
tinct from the form on Ranunculus there being no evidence that it is 
a conidial state of Erutyloma. The stroma from which the sporules 
spring is often spherical and these masses are often gregarious and 
crowded. Cylindrosporium clematidis E. & E. with different spots and 
epiphyllous acervuli can hardly be the same. I have not seen Sepioria 
thalictri E. & E. but judge from the description that it may not be 
distinct from this. Journ. Mycol. 4: 49, (1888). 
Entomosporium maculatum Lev. var. domesticum Sacc. The speci¬ 
mens that I have referred to this variety were collected in Burnett 
Co. on mountain ash. The sporules are mostly 16-20 x 8-9 /x. One col¬ 
lection on Amelanchicr spicata has sporules of about the same dimen¬ 
sions. Specimens on quinces from the Madison market, obtained by 
Mr. A. G. Johnson, show sporules 20—23 x 7—10 p. It is doubtful if 
the variation in size is of any taxonomic significance. 
Gloeosporium fragariae (Lib.) Mont. My measurements of the spor¬ 
ules of the fungus referred to this spe’cies range from 12-24 x 4-5 p. 
It was collected at Spooner. 
Marssonina coronaria (Ell. & Davis) This is Asoochyta ooronaria 
Ell. & Davis, 3rd supplementary list No. 580 and also Marsonia cor- 
onariae Sacc. & Dearn. (Ann. Mycol. 10, 3, 313.) 
Phragmidium disciporum (Tode) James. The form on Rosa 
blanda is Ph. americanum Diet, while that on Rosa woodsii (?) and 
R. pratincola (?) is Ph. rosae-arkansanae Diet. Wisconsin is included 
in the range of Ph. rosae setigerae Diet. which occurs on Rosa setigera
