“…The anther smuts of Caryophyllaceae , commonly referred to as the Microbotryum violaceum complex, form a monophyletic lineage within the genus Microbotryum . They are model organisms studied in many disciplines of fungal biology, for example, ecology (Thrall et al 1993), genomics (Hood 2005, Yockteng et al 2007), population studies (Lee 1981, Alexander & Antonovics 1995, Alexander et al 1996), life cycle studies (Schäfer et al 2010), geographic distribution (Hood et al 2010, Fontaine et al 2013), phylogeography (Vercken et al 2010), evolutionary history (López-Villavicencio et al 2005, Refrégier et al 2008), speciation (Devier et al 2010, Gladieux et al 2011), and phylogeny and systematics (Lutz et al 2005, 2008, Denchev et al 2009, Piątek et al 2012, Kemler et al 2013). …”

Currently, the monophyletic lineage of anther smuts on Caryophyllaceae includes 22 species classified in the genus Microbotryum. They are model organisms studied in many disciplines of fungal biology. A molecular phylogenetic approach was used to resolve species boundaries within the caryophyllaceous anther smuts, as species delimitation based solely on phenotypic characters was problematic. Several cryptic species were found amongst the anther smuts on Caryophyllaceae, although some morphologically distinct species were discernible, and most species were characterized by high host-specificity. In this study, anther smut specimens infecting Silene saxifraga were analysed using rDNA sequences (ITS and LSU) and morphology to resolve their specific status and to discuss their phylogenetic position within the lineage of caryophyllaceous anther smuts. The molecular phylogeny revealed that all specimens form a monophyletic lineage that is supported by the morphological trait of reticulate spores with tuberculate interspaces (observed in certain spores). This lineage cannot be attributed to any of the previously described species, and the anther smut on Silene saxifraga is described and illustrated here as a new species, Microbotryum silenes-saxifragae. This species clusters in a clade that includes Microbotryum species, which infect both closely and distantly related host plants growing in diverse ecological habitats. It appears possible that host shifts combined with changes to ecological host niches drove the evolution of Microbotryum species within this clade.

“…As a result, host specificity – and sometimes subtle morphological differences – has led to the division of this complex into a group of species, whose differences have been supported by DNA analyses (Freeman et al 2002, Lutz et al . 2005, 2008, Le Gac et al 2007, Refrégier et al 2008, Piątek et al 2012, 2013). Following a consolidated species concept approach (Quaedvlieg et al 2014), anther smuts on Caryophyllaceae are currently divided into 23 species that are usually highly host-specific (Deml & Oberwinkler 1982, 1983, Scholz & Scholz 1988, Vánky 1988, Chlebicki & Suková 2005, Lutz et al 2005, 2008, Denchev 2007a, 2007b, Denchev et al 2009, Denchev & Denchev 2011, Piątek et al 2012, 2013).…”

Yet, the process of disentangling this species complex is still not finished and several groups, such as species on Dianthus (Kemler et al 2013) or species on diverse, mostly non-European Silene species (Vánky 2012) still need to be resolved.…”

Anther smuts on Silene acaulis and S. uniflora from the Outer Hebrides, Scotland, UK), are analysed using morphological and molecular techniques, and found to represent Microbotryum silenes-acaulis and M. silenes-inflatae, respectively. This is the first identification of caryophyllaceous anther smuts in the Outer Hebrides according to modern species concepts and the first report of Microbotryum silenes-acaulis confirmed by molecular analysis from the British Isles. Additionally, the genetic structure of Microbotryum silenes-acaulis, based on all currently available ITS sequences, is analysed and discussed. Seven ITS genotypes are determined for Microbotryum silenes-acaulis, including three genotypes in North America and four genotypes in Europe. Compared to European accessions, all North American accessions share specific nucleotides and are genetically divergent.

“…in Europe and East Asia (Vánky 2012;Denchev et al 2013). However, recent molecular studies revealed that many morphologically defined polyphagous smuts and false smuts in fact represent complexes of host-specific independent cryptic or pseudocryptic species (Vánky and Lutz 2007;Bauer et al 2008;Lutz et al 2005Lutz et al , 2008Piątek et al 2011Piątek et al , 2012Piątek et al , 2013aSavchenko et al 2014a, b;Vasighzadeh et al 2014) and, therefore, Anthracoidea found on Carex koshewnikowii could be a species different than Anthracoidea sempervirentis. Thus, this study aims to resolve the systematic placement of Anthracoidea on Carex koshewnikowii using light and scanning electron microscopy and phylogenetic analyses using LSU rDNA sequences.…”

Phylogeny and morphology of Anthracoidea pamiroalaica sp. nov. infecting the endemic sedge Carex koshewnikowii in the Pamir Alai Mts (Tajikistan)

A novel Anthracoidea species, A. pamiroalaica on the endemic sedge Carex koshewnikowii, is described and illustrated from the Pamir Alai Mts in Tajikistan (Central Asia). The new species is phenotypically nearly identical with Anthracoidea sempervirentis, but clearly divergent genetically. Phylogenetic analyses based on LSU sequences showed affinity of Anthracoidea pamiroalaica to A. baldensis, A. rupestris, A. capillaris, and A. vankyi infecting host sedges in different Carex sections (Baldenses, Rupestres, Chlorostachyae, and Phaestoglochin, respectively), but not to A. misandrae, and A. sempervirentis, two sequenced species parasitic on host species from the section Aulocystis. This phylogenetic placement is briefly discussed in the context of Anthracoidea evolution.
