A PARTIAL LIST OF THE PARASITIC ASCOMYCETES OF IOWA

J. C. GJLMAN The paras1t1c fungi have been a subject of continued interest to Iowa botanists from the early collections of Bessey, Halsted and Holway to the present. This interest is evidenced by the large number of specimens deposited in the herbariums of the state and the listing of them in various scientific publications. ·These lists have been made for special groups such as the Erysi­ phaceae or for special regions as the list of "Wilson for Fayette County, but until the present no attempt has .been made to bring together the members of the entire g-roup of Ascomycetes of Iowa into a single publication. \Vith therecent advances in our knowledge of the ascomycetous life-cycle particularly the connecting of members of the Fungi Imperfecti with members of this group and with it the new views of the type of parasitism exhibited by Ascomycetes it was thought that a compilation of the available material from the literature and herbarium would be valuable as a reference and also as a start­ ing point for further investigations in this field. In this compilation the literature was covered as completely as possible and the material in the herbarium of Iowa State College, which consists chiefly in the collections of Dr. Pammel and parts of the Holway herbarium which are deposited therein, were re­ examined and listed in accordance with the changes that have been adopted in revising of nomenclature. In order to make the list rimst useful a host index to the fungi listed has been appended. Ascochyta pisi Lib. - M ycosphaerella pinodes Balansia hypoxylon (Pk.) Atk. Danthonia spicata (L.) Beauv.
