The spelling rachodes used by Vittadini in 1833 for a new species of Agaricus has often been considered a correct- able orthographical error for rhacodes. Use of the original spelling has however been occasional and was recently promoted by Vellinga and coworkers. The arguments used to support this practice, especially developed by Vellinga and Pennycook, when proposing conservation of rachodes in 2010 are refuted. It is shown that it is philologically illogical to assume an adjective rachodes could have been created, while the existing rhacodes was obviously meant. The use of the two spellings presented by Vellinga and Pennycook is shown to be incomplete. The conclusion is that rachodes should be corrected under Art. 60.1 to rhacodes, the spelling used for every other organism with that epithet, and that this correction is far more universal, including outside Europe, than the usage claimed for justifying a conservation of rachodes. The expenditure of energy caused by the Vellinga and Pennycook proposal shows that new ways to handle orthography of scientific names should be explored. [less ▲]

The rare tropical Gasteromycetes Lycogalopsis solmsii has been found twice at thirty years interval in the Singapore Botanic Gardens. From the most recent find a culture could be isolated, which allowed DNA extraction and sequencing of about 2000 bp from the nuclear ribosomal DNA. Comparison to a large sample of Basidiomycetes was only possible for a part of the large ribosomal subunit, but clearly indicated affiliation to the gomphoid-phalloid group, without any relationship to Lycoperdales or Agaricales, as stated in the Dictionary of the Fungi.

A study of the holotype (BPI) and isotype (SING) of Polyporus burkillii Lloyd shows that this ma- terial is homogeneous and does not belong to a species of the genus Polyporus as assumed by Ryvarden (1990) and Hattori (2001), but that Corner (1987) was correct in combining the name in Microporellus. At the specific level Corner however misinterpreted the taxon which should be in- cluded in M. clemensiae (Murrill) Ryvarden s.l. Further studies of Microporellus are needed and may show that this is a good species antedating other infudibuliform ones, especially M. inusitatus (Lloyd) Corner. The spelling of the name is discussed, the conclusion being that it should be corrected to Polyporus burkilliae. Microporellus burkillii (Lloyd) Corner ss. Corner is a good species that appar- ently lacks a name. [less ▲]

The development of the study of larger basidiomycetes, especially polypores, in the Malesian region is presented. The historical importance of the botanical gardens in Bogor and Singapore is emphasised and an overview of the mycological collection in Singapore is given. This includes several isotypes of taxa described by G.E. Massee, C.G. Lloyd and N. Patouillard, as well as paratypes and holotypes of taxa described by E.J.H. Corner. The problems linked to Corner’s material are discussed in the light of studies made in both Singapore and Edinburgh. The polypore collection in Singapore is a valuable resource for studying any geographical variation of fungal floras in the Malesian region and a unique tool for examining any temporal change in this flora, given the continuity of collections in the island since H.N. Ridley in 1892. [less ▲]

According to the chromalveolate hypothesis (Cavalier-Smith T. 1999. Principles of protein and lipid targeting in secondary symbiogenesis: euglenoid, dinoflagellate, and sporozoan plastid origins and the eukaryote family tree. J Eukaryot Microbiol 46:347-366), the four eukaryotic groups with chlorophyll c-containing plastids originate from a single photosynthetic ancestor, which acquired its plastids by secondary endosymbiosis with a red alga. So far, molecular phylogenies have failed to either support or disprove this view. Here, we devise a phylogenomic falsification of the chromalveolate hypothesis that estimates signal strength across the three genomic compartments: If the four chlorophyll c-containing lineages indeed derive from a single photosynthetic ancestor, then similar amounts of plastid, mitochondrial, and nuclear sequences should allow to recover their monophyly. Our results refute this prediction, with statistical support levels too different to be explained by evolutionary rate variation, phylogenetic artifacts, or endosymbiotic gene transfer. Therefore, we reject the chromalveolate hypothesis as falsified in favor of more complex evolutionary scenarios involving multiple higher order eukaryote-eukaryote endosymbioses. [less ▲]

STARESO (Station de REcherche Sous marine et Océanographique) is the marine and oceanographic research station of the University of Liège (Belgium) managed by the French company STARESO S.A.. Constructed in 1969, it is located near Calvi (Corsica, Western Mediterranean Sea) in an oligotrophic area chosen for the exceptional quality of its coastal waters STARESO offers to the oceanographers, by diving or with boats, a direct access to the sea. The variety of the accessible ecosystems is remarkable and unique in the Mediterranean basin: -the Bay of Calvi is characterized by healthy and very diverse biocenosis (e.g. Posidonia meadows, rocky and sandy communities, -a steep submarine canyon, with depths greater than 1 000 meters, is accessible in 15 minutes of navigation; -the Liguro-Provençal front, a major hydrologic structure, is situated between 10 and 15 miles of the coast. STARESO is accessible all the year for everybody and is functioning like an oceanographic research vessel. The Station is a platform for all oceanographic disciplines with a scientific expertise widely based on a long tradition of interdisciplinary work, and a direct access to time series of physical, chemical and biological data registered with automated systems and variety of sensors deployed in the Bay of Calvi since 30 years. This platform provides the opportunity to reach coastal, pelagic, benthic, deep systems with a manageable cost and ship requirements in a pristine zone. [less ▲]

Crustose corallines, crustose and erect brown algae, and sessile animals are major components of the epiphytic community of the Mediterranean seagrass Posidonia oceanica (L.) Delile. Production, biomass, and specific composition of this epiphyte-seagrass association are impacted by anthropogenic increase of nutrient load in this oligotrophic area. In this context, nitrogen uptake by P. oceanica and its epiflora was measured using the isotope N-15 at a 10 m depth in the Revellata Bay (Corsica, Mediterranean Sea). Epiflora components showed various seasonal patterns of biomass and abundance. The epiphytic brown algae appeared at the end of spring, later than the crustose corallines, and after the nitrate peak in the bay. Because of their later development in the season, epiphytic brown algae mostly rely on ammonium for their N needs. We hypothesize that the temporal succession of epiphytic organisms plays a crucial role in the N dynamics of this community under natural conditions. The epiphytic brown algae, which have a growth rate one order of magnitude greater than that of crustose corallines, showed lower N-uptake rates. The greater N-uptake rates of crustose corallines probably reflect the greater N requirements (i.e., lower C/N ratios) of red algae. We determined that the epiflora incorporated ammonium and nitrate more rapidly than their host. Nevertheless, when biomass was taken into account, P. oceanica was the most important contributor to N uptake from the water column by benthic macrophytes in this seagrass bed. [less ▲]

Background: The emergent nature of atypical myopathy or atypical myoglobinuria (AM) necessitates precise description of its clinical and epidemiologic features. Purpose: To define key features of AM to help practitioners recognize the disease and to advise owners to take preventive measures. Animals: Belgian cases of AM confirmed by histology (CC horses; n = 57) from autumn 2000 to spring 2005 were included in the study. Co-grazing horses (Co-G horses; n = 77) that remained free of any abnormal clinical signs constituted a control croup. Methods: History, environmental characteristics, clinical signs, and laboratory results associated with AM were determined by a retrospective case series study. Results: Young horses in poor or normal body condition were found to be at risk for AM. Pastures were characterized by poor natural drainage and vegetation of low nutritional value. Features of AM were seasonal occurrence, apparent link with weather conditions fie, lack of solar radiation with no heavy frost and an excess of precipitation or relative humidity), sudden onset of clinical signs, and rapid death. Evaluation of serum creatine kinase activity indicated severe muscle destruction in CC horses and subclinical disease in a few Co-G horses. Conclusions: The association of AM with specific environmental conditions and individual animals suggests that young horses should not be pastured on bare premises subject to humidity when the weather has been very wet and cold for several days. Management of AM outbreaks should include control of Co-G horses who are apparently healthy. [less ▲]

Seven filtered seawater samples (depths between 30 and 55 m) collected during the SAZ project of the Austral summer of 1997-1998 were used for a simultaneous study of the picophytoplankton pigments based on high-performance liquid chromatography (HPLC) analyses and flow cytometry, and of the molecular diversity of the picophytoplankton based on their rDNA sequences. The sampling sites could be divided into three temperature zones, distinguished by their proximity to the Sub-Antarctic and Polar Fronts. HPLC analysis of total chlorophylls and carotenoids showed fairly low phytoplankton concentrations (77-262 ng chl al(-1)), with minimal values of the pigments in the two samples of the Polar Front Zone around 54degreesS (water temperature of 4degreesC at time of collection). In this zone, a similar decrease of particles, identified as cyanobacteria on the basis of their fluorescence, was observed by flow cytometry. Sequences very similar to the 16S rDNA sequence of Synechococcus WH8103 were present in all samples. This Synechococcus genotype is thus found in the Southern Ocean in addition to the Atlantic and Pacific locations where it has been previously observed. The yield of PCR products was lower in the two samples taken in the Polar Front Zone, showing a good agreement between molecular and pigment data. 16S rDNA sequences of plastids of eukaryotic algae also were retrieved, mostly related to those of an environmental clone called OM164, which has not been cultivated but has phylogenetic affinities to the Raphidophyceae.

In Posidonia oceanica (L.) Delile, anthesis induces a decrease in the number of juvenile leaves resulting in a significant reduction in the number of leaves on the flowering shoots. All the leaves of the flowering shoots are narrower than the leaves of nonflowering shoots. A modification of the leaf growth also appears in flowering shoots: the oldest leaves are longer and the leaves induced during or after anthesis are shorter. At 10 m depth, in the Bay of Calvi, anthesis lasts roughly 3 months and the flowering is induced 7 months before anthesis. [less ▲]
