W. A. KELLERMAN, Ohio State University. It is proposed to distribute exsiccata of the Ohio species of Fungi, issuing small fascicles from time to time as material may be available. The original descriptions of all the species, or that given in connection with the first use of the binomial or technical designation, will be printed on the labels in addition to the data usually given. Complete synonomy will not be attempted. The number of copies will be limited, but it is hoped that all mycologists who might be especially interested in the specimens, and those wishing to exchange, may be furnished with the fascicles as they appear. Fascicle 1, containing Nos. 1 to 16, issued November 20, 1901, represents the following species: 1. Aecidium impatientis Schw., on Impatiens biflora Walt. 2. Aecidium porosum Peck, on Vicia americana Muhl. 3. Aecidium sambuci Schw., on Sambucus canadensis L. 4. Cintractia sorghi (Link), on cultivated Sorghum (S. vulgare Pers.) 5. Cintractia sorghi (Link), obtained by inoculation. 6. Cintractia sorghi (Link), on Broom Corn (S. vulgare Pers.) 7. Cintractia sorghi (Link), obtained by inoculation. 8. Peronospora arthuri Farl., on Onagra biennis (L.) Scop. 9. Phyllosticta asiminae E. & K., on Asimina triloba (L.) Dun. 10. Puccinia helianthi Schw., on Helianthus divaricatus L. 11. Puccinia helianthi Schw., on Helianthus mollis Lam. 12. Puccinia marie-wilsoni Clinton, on Claytonia virginica L. 13. Puccinia podophylli Schw., on Podophyllum peltatum L. 14. Puccinia smilacis Schw., on Smilax glauca Walt. 15. Septoria podophyllina Peck, on Podophyllum peltatum L. 16. Ustilago zeae (Beckm.) Ung., on Zea mays L. Thanks are extended to the mycologists who have rendered advice and assistance, especially to Messrs J. B. Ellis, J. C. Arthur, A. P. Morgan, and C. G. Lloyd. Acknowledgment for assistance in collecting will be found on the labels accompanying the several specimens. The labels to the sixteen specimens of the first Fascicle are here reproduced. 1.
