This species has been previously recorded only from three localities in the Pribilof Islands in the Bering Sea, the Kenai Peninsula (Alaska), and British Columbia. A description, illustrations, and a distribution map are provided. A list of the known Anthracoidea species in the Russian Far East is also given.

Tilletia tripogonellae (Tilletiaceae), A New Smut Fungus on Tripogonella spicata (Poaceae) from Argentina

A new smut fungus from Argentina, Tilletia tripogonellae T. Denchev & Denchev (Tilletiaceae),... more A new smut fungus from Argentina, Tilletia tripogonellae T. Denchev & Denchev (Tilletiaceae), on Tripogonella spicata (Poaceae : Cynodonteae), is described and illustrated. It differs from all other species of Tilletia by being specialized on Tripogonella. Morphologically it differs from other known species of Tilletia on host plants from the subtribe Tripogoninae (Tilletia eragrostiellae, T. poonensis, T. savilei, T. tripogonis) by having a reticulate (vs. tuberculate or echinate) spore wall. A key to the smut fungi, that infect Eragrostiella, Tripogonella, Oropetium, and Tripogon, is provided.

It was known only from Australia and New Zealand. Restiosporium is reported here for the first time outside Australasia, based on a specimen of R. spathacei on Dapsilanthus disjunctus from Thailand. A description and illustrations are provided for this smut fungus. Dapsilanthus disjunctus is a new host plant for Restiosporium spathacei.

It differs from all other species of Entyloma by host specialization on Eranthis and by having longer (≤35(–38) μm) spores and thicker (≤10(–12) μm) spore walls. ITS rDNA sequence analysis indicates that the new species does not cluster with other species of Entyloma on Ranunculaceae.

Its species infect plants belonging to three, monocotyledonous families, Commelinaceae (Commelina and Tinantia), Juncaceae (Juncus and Luzula), and Cyperaceae (Cyperus). Th ere 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.

A total of 43 species in 11 genera are treated and illustrated by photographs of sori, microphotographs of spores in LM and SEM, and distribution maps. Two species, Anthracoidea pseudofoetidae and Urocystis tothii, are recorded as new from North America. Thirteen species, Anthracoidea altera, A. capillaris, A. limosa, A. liroi, A. pseudofoetidae, A. scirpoideae, A. turfosa, Microbotryum lagerheimii, M. stellariae, Schizonella elynae, Stegocintractia luzulae, Urocystis fischeri, and U. tothii, are reported for the first time from Greenland. Three new fungus-host combinations, Anthracoidea capillaris on Carex boecheriana, Anthracoidea pseudofoetidae on Carex maritima, and Urocystis tothii on Juncus biglumis, are given. Five plant species are reported as new hosts of smut fungi in Greenland, namely, Carex nigra for Anthracoidea heterospora, C. canescens for Anthracoidea karii, C. fuliginosa subsp. misandra for An...

Additionally, Persicaria longiseta and P. posumbu are newly recorded as South Korean hosts of Sphacelotheca hydropiperis, and Echinochloa crus-galli is a new South Korean host for Ustilago trichophora.

It differs from all other species of Tilletia by specialization on Triraphis. Tilletia triraphidis is distinguished from the known smut fungi on host plants in the tribe Triraphideae (Ustilago neyraudiae, U. latzii, and U. triraphidis) by having sterile cells and reticulate spores. A key to the smut fungi that infect Neyraudia and Triraphis is also provided.

The type specimen of S. rhytachnes-rottboellioidis was re-studied. A new combination, Anthracocystis rhytachnes-rottboellioidis , is proposed to accommodate this fungus. The new record extends the geographical range of A. rhytachnes-rottboellioidis from Central East Africa to West Africa. A new combination, Anthracocystis urelytri , is introduced to accommodate Sorosporium urelytri . A key to the smut fungi of Anthracocystis on Rhytachne and Urelytrum is provided.
