Item 4. The recent death of Thomas Meehan, horticulturist and botanist, removes from the list of active American workers one whose numerous, accurate and original observations contributed greatly to the advancement of botanical science.
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 Vicia, 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 inadvertency 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 Muhl.
