NOTE AND CORRECTION TO OHIO FUNGI EXSICCATI. 
W. A. KELLERMAN. 
A critical inspection of the nomenclature used for the first 
Fascicle of the Ohio Fungi might seem to warrant the conclusion 
that the judgment of more recent workers is sometimes ignored 
and that a too conservative course has been adopted. But it 
should be remembered that the main purpose is to furnish Ohio 
material accompanied by names (occasionally synonyms) that 
were undoubtedly applied to the species represented. I have 
preferred to use for the Rust on Sunflower, Puccinia helianthi, 
rather than P. tanaceti — recent work on other species suggesting 
that with this also when fully studied, a physiological distinction 
may supplement the too insignificant morphological difference. 
Again, I have used Aecidium album, which Clinton applied to 
the first stage of the Uredine found on Yicia, not ignorant of the 
fact that Dietel gives this as a stage of Uromyces albus — but 
should not this first be substantiated by cultures? It is to be 
added that through iuadvertancy Peck’s later name (Aecidium 
porosum) was used, hence here follows a corrected label with 
both Clinton’s and Peck’s descriptions : 
2. Aecidium album Clinton. 
Aecidium porosum Peck. 
On Vicia americana Mulil. 
Lakeside, Ottawa Co., O. May 17, 1901. 
Coll. W. A. Kellerman. 
“ Aecidium album Clinton, spots none ; peridia scattered, short, 
white, the margin subentire ; spots subglobose, white, about .0008 
inches in diameter.” Report on the State Museum, State of New 
York, 26 : 78. 1873. 
“Aecidium porosum, I’k. Spots none; cups crowded, deep- 
seated, broad, wide-mouthed, occupying the whole lower surface 
of the leaf to which they give a porous appearance ; spores orange- 
colored, subangnlar, .0008-.001 inch in length.” Botanical Gaz- 
ette, 3:34. April, 1878.
