In May 1966, the author collected the inoperculate discomycete Verpatinia calthicola Whetzel (Sclerotiniaceae) near Třeboň (South Bohemia), on decaying leaves of Caltha palustris. This species was previously known only from North America and, more recently, England. The South Bohemian material matches the original description. The small size of Verpatinia spp. makes them easy to overlook, but further findings in suitable habitats are expected.
