Additional records to three Tilletia species are reported from Africa: T. oplismeni-cristati on Acroceras calcicola from Madagascar, T. vittata on Oplismenus burmannii from Senegal, and T. perotidis on Perotis patens from Madagascar. Acroceras calcicola is a new host association for T. oplismeni-cristati, currently known only on species of Oplismenus. Descriptions, illustrations, and taxonomic notes are provided for these taxa.

Two smut fungi, Bauerago vuyckii on Luzula alpina and Moreaua kochiana on Schoenus nigricans and Schoenus ×scheuchzeri, are reported for the first time from Austria. Luzula alpina is a new host association for Bauerago vuyckii. Descriptions and illustrations are provided for these taxa.

Bauerago (with B. abstrusa on Juncus as the type species) is a small genus in the Microbotryales. Its species infect plants belonging to three, monocotyledonous families, Commelinaceae (Commelina and Tinantia), Juncaceae (Juncus and Luzula), and Cyperaceae (Cyperus). There are four Bauerago species on hosts in the Commelinaceae (three species on Commelina and one on Tinantia). Bauerago commelinae on Commelina communis was studied by molecular and morphological methods. Phylogenetic analyses using rDNA (ITS, LSU, and SSU) sequences indicate that B. commelinae does not cluster with other species of Bauerago on Juncaceae. For accommodation of this smut fungus in the Microbotryaceae, a new genus, Kalmanago, is introduced, with four new combinations: Kalmanago commelinae (Kom.) Denchev et al., K. combensis (Vánky) T. Denchev et al., K. boliviana (M. Piepenbr.) T. Denchev et al., and K. tinantiae (J.C. Lindq.) T. Denchev et al. A lectotype is designated for K. commelinae.
