Two new records of smut fungi for Panama and new combinations into the genus Tolyposporium
Tropical Plant Pathology, 2013Co-Authors: Meike Piepenbring, Efsun Yilmaz, Jascha L. F. WeisenbornAbstract:Two species of smut fungi (Basidiomycota) are reported here for the first time for Panama. Narasimhania alismatis (Doassansiales) was found on Sagittaria guayanensis and Tolyposporium kuwanoanum (Ustilaginales) on Cyperus tenuis, a new species of host plant. The name of the latter fungus is a new combination based on the currently accepted name Ustanciosporium kuwanoanum. This species belongs to the genus Tolyposporium because of sori with peridia, teliospores in balls, teliospores without hyaline appendages, and LSU rDNA sequence data. Ustanciosporium cyperi is morphologically rather similar to T. kuwanoanum, so it is also placed into the genus Tolyposporium. The concept of the genus Tolyposporium is discussed.

Aurantiosporium, a new genus forUstilago subnitens (Ustilaginales)
Plant Systematics and Evolution, 1996Co-Authors: Meike Piepenbring, Kalman Vanky, Franz OberwinklerAbstract:A new genus, Aurantiosporium Piepenbring, Vánky & Oberwinkler ( Ustilaginales ), is proposed for the smut species Ustilago subnitens Schröter & Hennings on Scleria melaleuca Reichb. The soral morphology, teliospore development, the ultrastructure of the teliospore wall and teliospore germination of Aurantiosporium subnitens , studied on collections from Costa Rica, are described for the first time. The character set of A. subnitens including intercellular teliospore development, spores in irregular groups and light coloured spore walls with numerous layers in TEM is neither known from Ustilago nor Cintractia nor any other smut species.

Rhodosporidium Babjevae, a New Heterothallic Yeast Species (Ustilaginales)
Systematic and Applied Microbiology, 1993Co-Authors: Wladyslaw I. GolubevAbstract:Summary A description of a new red-pigmented non-ballistosporogenous teliospore-forming yeast is given. The yeast does not mate with the other species of the genus Rhodosporidium and differs from them by teliospore or metabasidium morphology, by physiological properties and by sensitivity to Rhodotorula mucilaginosa mycocins. The type strain of Rhodosporidium babjevae is VKM Y-2275, the allotype one is VKM Y-2276.

the Ustilaginales as plant pests and model systems
Fungal Genetics and Biology, 2002Co-Authors: Alfredo D Martinezespinoza, Maria D Garciapedrajas, Scott E GoldAbstract:The Ustilaginales are a vast and diverse group of fungi, which includes the plant pathogenic smuts that cause significant losses to crops worldwide. Members of the Ustilaginales are also valuable models for the unraveling of fundamental mechanisms controlling important biological processes. Ustilago maydis is an important fungal model system and has been well studied with regard to mating, morphogenesis, pathogenicity, signal transduction, mycoviruses, DNA recombination, and, recently, genomics. In this review we discuss the life cycles of members of the Ustilaginales and provide background on their economic impact as agricultural pests. We then focus on providing a summary of the literature with special attention to topics not well covered in recent reviews such as the use of U. maydis in mycovirus research and as a model for understanding the molecular mechanisms of fungicide resistance and DNA recombination and repair.
