“…As in the phylogenetics analyses of Pedersen & Hedenäs (2003 and Pedersen et al (2007), B. alpinum is clearly separated from B. gemmiparum, and, according to our data, much closer to B. mildeanum. These three species have always been considered as belonging to section Alpiniformia, but molecular data suggest that B. gemmiparum may be more closely related to the species of the B. dichotomum complex.…”

Bryum mildeanum, a rare species in the Iberian Peninsula, has frequently been confused with B. alpinum. In this study we provide new gametophytic and sporophytic (obtained by SEM) characters that can be used to separate the two and B. mildeanum is described and lectotypified. A molecular study based on two chloroplast DNA regions (trnL-F and trnG) was performed. The results suggest the evolutionary independence of B. mildeanum and B. alpinum, and the separation of both from B. gemmiparum, a species generally placed in the same subsection (Section Bryum, subsection Alpiniformia) as the other two.

“…Being a low-copy marker, trnG ucc overcomes drawbacks of utilizing multiple-copy genes and introns (Á lvarez & Wendel, 2003). Recently, trnG ucc intron sequences were used in phylogenetic studies of different groups of Streptophytes (Pedersen & Hedenäs, 2003;Turmel et al, 2005;Bayer et al, 2009;Neustupa et al, 2010). Genomic DNA was extracted from the strains (Table 1) according to the following method: After centrifugation, cells were disrupted by shaking for 10 min with glass beads at 1,800 rpm in Retch-MM200.…”

A novel, combined approach to assessing species delimitation and biogeography within the well-known desmid species Micrasterias fimbriata and M. rotata (Desmidiales, Steptophyta) Abstract Morphological species of freshwater microalgae often have broad geographic distribution. However, traditional species concepts have been challenged by the results of molecular phylogenetic analyses that mostly indicate higher diversity than was previously recognized by purely morphological approaches. A degree of phenotypic differentiation or different geographic distribution of species defined by molecular data remains largely unknown. In this study, we analyzed a pair of well-known and widely distributed desmid species (Micrasterias fimbriata and M. rotata) and tested for their phylogenetic and Electronic supplementary material The online version of this article (

“…Pedersen and Hedenäs (2003) used information from seven chloroplast DNA sequences (i.e. rbc L, psb A, rps 4, the rpl 16 intron, the trn L– trn F region, the trn G intron, and the atp B– rbc L intergenic spacer) and morphological characteristics in a phylogenetic analyses of the Bryaceae.…”

“…Because the placement of P. zierii was deeply nested within the B. capillare – B . radiculosum clade, Pedersen and Hedenäs (2003) suggested that the species comprising this clade should be accommodated in the genus Plagiobryum Lindb. Similar results also emerged from other studies; for example, B. pallescens aligned in a clade with P. zierii from rps 4/ trn L‐F data (Cox & Hedderson, 2003); and B. algovicum , B .…”

Phylogeny of Ptychostomum (Bryaceae, Musci) inferred from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) and chloroplast rps4

The phylogeny of Ptychostomum was first undertaken based on analysis of the internal transcribed spacer (ITS) region of the nuclear ribosomal (nr) DNA and by combining data from nrDNA ITS and chloroplast DNA rps4 sequences. Maximum parsimony, maximum likelihood, and Bayesian analyses all support the conclusion that the reinstated genus Ptychostomum is not monophyletic. Ptychostomum funkii (Schwägr.) J. R. Spence (≡Bryum funkii Schwägr.) is placed within a clade containing the type species of Bryum, B. argenteum Hedw. The remaining members of Ptychostomum investigated in the present study constitute another well‐supported clade. The results are congruent with previous molecular analyses. On the basis of phylogenetic evidence, we agree with transferring B. amblyodon Müll. Hal. (≡B. inclinatum (Brid.) Turton ≡Bryum archangelicum Bruch & Schimp.), Bryum lonchocaulon Müll. Hal., Bryum pallescens Schleich. ex Schwägr., and Bryum pallens Sw. to Ptychostomum.
