The Cladonia furcata complex treated here comprises C. farinacea, C. furcata, C. multiformis, C. scabriuscula, C. stereoclada, and C. subrangiformis. The well-known taxonomic complexity of this group is caused by wide phenotypic variation and high morphological similarity among the species, for which reason we investigated the distribution in the phylogeny of the phenotypic characters traditionally used to distinguish the species in this complex. A phylogenetic analysis of the C. furcata complex is presented here, based on three loci (ITS rDNA, IGS rDNA and RPB2), representing specimens from a broad geographical range (Europe, North America and New Zealand). The phylogenetic reconstructions were performed using Maximum Likelihood and Bayesian analyses. In addition, 14 features traditionally used for species delimitation within this complex were mapped onto the Bayesian phylogeny. All the species currently accepted, with the exception of C. stereoclada, turned out to be polyphyletic. Most of the phenotypic characters studied are highly homoplasious with the exception of the podetium type. The solid podetia represent a diagnostic character of C. stereoclada.

A new nonlinear travelling-wave solution for a flow through an isothermal square duct is discovered. The solution is found by a continuation approach in parameter space, starting from a case where the fluid is heated internally. The Reynolds number for which the travelling wave emerges is much lower than that of the solutions discovered recently by an analysis based on the self-sustaining process (Wedin et al., Phys. Rev. E, vol. 79, 2009, p. 065305; Uhlmann et al., Advances in Turbulence XII, 2009, pp. 585–588). Furthermore, the new travelling-wave solution is shown to be unstable from the onset.

The phylogeny of Lecanoromycetes (Ascomycota, Fungi) is investigated utilizing parsimony and Bayesian Markov Chain Monte Carlo analyses, of combined nLSU rDNA and mtSSU rDNA sequence datasets. The results suggest that Acarosporaceae, Candelariaceae, Phlyctis and Pycnora are not members of the monophyletic Lecanorales, and that Timdalia and Pleopsidium are members of a monophyletic Acarosporaceae. Pycnora, Candelariaceae and Acarosporaceae form a monophyletic group. Umbilicariaceae, Hypocenomyce scalaris, H. friesii, Ophioparmaceae, Boreoplaca, Elixia and Fuscidea form either a basal paraphyletic assemblage in Lecanoromycetes, or a monophyletic group which is the sister-group to Lecanorales and the rest of Lecanoromycetes (excluding Acarosporaceae). The Acarosporaceae forms a group with Pycnora and Candelariaceae, which may be outside the Lecanoromycetes. Chaetothyriales, Verrucariales, Eurotiales, Lichinales and Mycocaliciales form a monophyletic group, but with low support. We briefly discuss incongruence between datasets from different genetic markers, comparing the differences between the separate parsimony analyses, where the ILD test indicated a very significant incongruence. The phylogenetic significance of ascus-types that have influenced most recent Ascomycota classifications heavily is also discussed, and we finally point out risks with formalizing classifications too early.

Three-dimensional travelling wave solutions are found for pressure-driven fluid flow through a circular pipe. They consist of three well-defined flow features – streamwise rolls and streaks which dominate and streamwise-dependent wavy structures. The travelling waves can be classified by the $m$-fold rotational symmetry they possess about the pipe axis with $m\,{=}\,1,2,3,4,5$ and $6$ solutions identified. All are born out of saddle-node bifurcations with the lowest corresponding to $m\,{=}\,3$ and traceable down to a Reynolds number (based on the mean velocity) of 1251. The new solutions are found using a constructive continuation procedure based upon key physical mechanisms thought generic to wall-bounded shear flows. It is believed that the appearance of these new alternative solutions to the governing equations as the Reynolds number is increased is a necessary precursor to the turbulent transition observed in experiments.

The phylogeny of the Agyriales was investigated using nucleotide sequences of ITS1, 5.8S, and ITS2 rDNA. Sequences of these regions from 15 new sequences of 13 agyrialean fungi were aligned to those of four representatives of Ostropales used as outgroup. Six different alignments were analysed cladistically using maximum parsimony. The Agyriales were supported as a monophyletic group in the strict consensus tree and the synonymy of the Rimulariaceae and Saccomorphaceae was confirmed. The Schaereriaceae is also shown to belong to the Agyriaceae. The distribution of selected characters in the Agyriales is investigated and it is shown that the ascus type is variable within the group, while the ascoma ontogeny is invariant within the Agyriaceae. Trapelia as usually circumscribed is polyphyletic. The T. geochroa group is not closely related to Trapelia s. str. and the new genus Ainoa is described to accommodate T. geochroa and T. mooreana.

SSU rRNA gene sequences of Anamylopsora pulcherrima (Anamylopsoraceae), Placopsis gelida, Trapelia involuta and T. placodioides (Agyriaceae) were determined and aligned with the corresponding sequences of 39 other ascomycetes. Phylogenetic analysis (maximum parsimony, spectral analysis) of these sequences placed the Agyriineae outside the Lecanorales and suggested a sister group relationship to Ostropales/Pertusariales. The resurrection of the order Agyriales is proposed based on molecular and morphological data, such as faintly amyloid asci opening by dehiscence. The sequence data support the two families Agyriaceae and Anamylopsoraceae to be accommodated within the order Agyriales. The Agyriales, Ostropales and Pertusariales can be placed in the class Lecanoromycetes.
