Abstract

Lepraria cryptovouauxii is described as a new semicryptic species similar to L. vouauxii, from which it differs geographically (South America) and phylogenetically; both species differ in nucleotide position characters in nucITS barcoding marker. Lepraria harrisiana is reported as new to South America and L. nothofagi as new to Antarctica, Bolivia, and Peru. Lepraria incana (South American records are referred to L. aff. hodkinsoniana) and L. vouauxii (most South American records are referred to L. cryptovouauxii) should be excluded at least temporarily from the lichen list of South America. All records previously referred to as L. alpina from Bolivia and Peru belong to L. nothofagi. Most of Bolivian records of L. pallida belong to L. harrisiana. Lepraria borealis and L. caesioalba should be included in L. neglecta. Lepraria achariana, L. impossibilis, and L. sipmaniana are sequenced for the first time.

SEAVIEW and PHYLO_WIN: two graphic tools for sequence alignment and molecular phylogeny

N Galtier, C Gautier, M Gouy (1996)

SEAVIEW and PHYLO_WIN are two graphic tools for X Windows-Unix computers dedicated to sequence alignment and molecular phylogenetics. SEAVIEW is a sequence alignment editor allowing manual or automatic alignment through an interface with CLUSTALW program. Alignment of large sequences with extensive length differences is made easier by a dot-plot-based routine. The PHYLO_WIN program allows phylogenetic tree building according to most usual methods (neighbor joining with numerous distance estimates, maximum parsimony, maximum likelihood), and a bootstrap analysis with any of them. Reconstructed trees can be drawn, edited, printed, stored, evaluated according to numerous criteria. Taxonomic species groups and sets of conserved regions can be defined by mouse and stored into sequence files, thus avoiding multiple data files. Both tools are entirely mouse driven. On-line help makes them easy to use. They are freely available by anonymous ftp at biom3.univ-lyon1.fr/pub/ mol_phylogeny or http:@acnuc.univ-lyon1.fr/, or by e-mail to galtier@biomserv.univ-lyon1.fr.

Cryptic species in lichen-forming fungi

Ana Crespo, H. Thorsten Lumbsch (2010)

This contribution provides a synopsis of the presentations and discussions during the SIG session on cryptic speciation in lichen-forming fungi held during IMC9. In several cases, a re-examination of morphology against the background of molecular phylogenetic evidence revealed, sometimes subtle, morphological and/or chemical characters, supporting the distinction of particular clades at species level. However, there are also examples of cryptic species in which no morphological characters could be identified to distinguish between lineages. Several cases were presented in which distinct lineages are correlated with biogeographical patterns. When and how to name cryptic species was debated, and the use of terms such as “complex” or “aggregate” commended where the taxa formed part of a single lineage.
