Schizonella caricis-atratae (Ustilaginomycetes): a new cryptic species on Carex atrata from Austria

Abstract

Based on DNA-fingerprinting, ITS-DNA sequencing and physiological characteristics, a new species of Schizonella, Sch. caricis-atratae, is described. Sch. caricisatratae is a so-called cryptic species, i.e. morphologically it is identical to Sch. melanogramma, but differs in physiological and molecular phylogenetic characters. Sch. caricisatratae can be distinguished by the following tests: growth on myo-inositol, D,L-lactate, salicine, maltose, αmethyl-Dglucoside, butane-2,3-diol, and D-turanose, at 30°C; no growth on galactose. Sch. caricis-atratae can be isolated from Carex atrata. The type strain is HB 3, CBS 123477.

Melanoxa, a new genus in the Urocystidales (Ustilaginomycotina)

“…The proposal of a new species is encouraged by current results in other smut fungal groups where so called "cryptic" species were revealed by combined morphological and molecular analyses. Both morphological differences and differences in base sequences maybe small or even lacking (e.g., Bauer et al 2008;Denchev et al 2009;Kemler et al 2009;Le Gac et al 2007;Lutz et al 2005Lutz et al , 2008Prillinger et al 2009;Vánky andLutz 2007, 2010). Overall host specificity of smut fungal species seems to be in higher gear than previously thought not only on the level of host genera but rather on the level of host species.…”

Molecular characterization of the closely related Debaryomyces species: Proposition of D. vindobonensis sp. nov. from a municipal wastewater treatment plant

“…The yeast isolates from the wastewater were characterized on the basis of their phenotypic properties using standard methods previously described by Yarrow (1998) and Prillinger et al (2009). Their sporulation ability was tested at 15 C, 20 C and 25 C on three media, namely McClary s acetate agar (0.1% glucose, 0.18% potassium chloride, 0.82% sodium acetate trihydrate, 0.25% yeast extract, 1.5% agar), 5% malt extract agar (5% malt extract, 2% agar) and YM agar (1% glucose, 0.3% yeast extract, 0.3% malt extract, 0.5% peptone, 2% agar).…”

New records of Microbotryum species parasitizing Caryophyllaceae from Ukraine

“…Thus, in the new check-list of smut fungi (Vánky 2005a) 14 additional species were included. Currently, there are 38 species which were described or collected after 1994 in Europe (Almaraz, Telleria 1998;Bauer et al 2008;Denchev 2007;Denchev, Giraud and Hood 2009;Lutz et al 2005Lutz et al , 2008Lutz, Vánky 2009;Piątek 2006;Prillinger et al 2009;Vánky 1998Vánky , 2003Vánky , 2005aVánky ,b, 2007Vánky , 2008aVánky ,b, 2009Vánky and Berner 2003;Vánky, Horita and Jage 2005a;Vánky, Jage and Scholz 2005b;Vánky et al 2008;Vánky, Lutz 2007;Vánky, Scholz 2001 (Denchev 2007;Denchev et al 2009;Lutz et al 2005Vánky, Berner 2003). Microbotryum jehudanum (Zundel) Vánky was found for the first time in the territory of Europe .…”
