That northeastern Iowa is a rich field for the mycologist is well known to those in any degree acquainted with the work of Prof. Holway while a resident of Decorah. From this region came numerous new species and here was gathered much information concerning others already known. While from its nearness to Decorah the region about Fayette cannot offer such facilities for pioneer work as did Decorah, yet it is a most excellent base from which to study the mycological flora of this section of Iowa. Lying as it does on the borderland between the Transitional and Upper Austral zones and midway between the plains of the west and the forests of the east this section of the state is a strategic point, so to speak. It was, therefore, with no small pleasure that I looked forward to my field work in this region. The results have far excelled my expectations
