@article{binder2005phylogenetic, abstract = {Phylogenetic relationships of resupinate Homobasidiomycetes (Corticiaceae s. lat. and others) were studied using ribosomal DNA (rDNA) sequences from a broad sample of resupinate and nonresupinate taxa. Two datasets were analysed using parsimony, a'core'dataset of 142 species, each of which is represented by four rDNA regions (mitochondrial and nuclear large and small subunits), and a 'full' clataset of 656 species, most of which were represented only by nuclear large subunit rDNA sequences. Both datasets were analysed using traditional heuristic methods with bootstrapping, and the full clataset was also analysed with the Parsimony Ratchet, using equal character weights and six-parameter weighted parsimony. Analyses of both datasets supported monophyly of the eight major clades of Homobasicliomycetes recognised by Hibbett and Thorn, as well as independent lineages corresponding to the Gloeophyllum clade, corticioid clade and jaapia argillacea. Analyses of the full clataset resolved two additional groups, the athelioid clade and trechisporoid clade (the latter may be nested in the polyporoid clade). Thus, there are at least 12 independent clades of Homobasicliomycetes. Higher-level relationships among the major clades are not resolved with confidence. Nevertheless, the euagarics clade, bolete clade, athelioid clade and jaapia argillacea are consistently resolved as a monophyletic group, whereas the cantharelloid clade, gomphoid-phalloid clade and hymenochaetoid clade are placed at the base of the Homobasidiomycetes, which is consistent with the preponderance of imperforate parenthesomes in those groups. Resupinate forms occur in each of the major clades of Homobasidiomycetes, some of which are composed mostly or exclusively of resupinate forms (athelioid clade, corticioid clade, trechisporoid clade,jaapia). The largest concentrations of resupinate forms occur in the polyporoid clade, russuloid clade and hymenochaetoid clade. The cantharelloid clade also includes many resupinate forms, including some that have traditionally been regarded as heterobasidiomycetes (Sebacinaceae, Tulasnellates, Ceratobasidiales). The euagarics clade, which is by far the largest clade in the Homobasidiomycetes, has the smallest fraction of resupinate species. Results of the present study are compared with recent phylogenetic analyses, and a table summarising the phylogenetic distribution of resupinate taxa is presented, as well as notes on the ecology of resupinate forms and related Homobasidiomycetes.}, author = {Binder, M. and Hibbett, D.

We monthly collected water samples of both water bodies from July 2003 to June 2004. The baiting method was used to gain an insight into the occurrence of aquatic Oomycetes. A total of 14 species of aquatic Oomycetes belonging to the orders Saprolegniales, Leptomitales and Olpidiopsidales could be isolated of both water bodies. Numerous saprophytic isolates of Rhizophydium Schenk (Chytridiomycetes), Rhizophydium carpophilum (Zopf) Fischer, parasitic on Oomycetes, and additionally one species of Plasmodiophoromycetes, Woronina polycystis Cornu could be isolated. Many isolates of Saprolegniales attributable to the genera Achlya Nees, Dictyuchus Leitgeb, Saprolegnia Nees and Pythium Pringsheim (Pythiales), which could only be identified on generic level, could be isolated as well. The species were examined and discussed with respect to their occurrence in the stagnant water Aue Lake and/or in the running water of the river Fulda. Half of the isolated species only occurred in one of the water bodies. In this study the occurrence of Achlya proliferoides Coker could be documented for Germany for the first time. The trophic status of the Aue Lake and of the classification of water quality of the river Fulda were determined by limnological-chemical parameters obtained by simultaneous investigations of both water bodies.}, author = {Riethmuller, A. and Langer, E.}, interhash = {59886a1028d08716637365e8f744e4d1}, intrahash = {3761f7ba34d31b312f03c5562bb78566}, journal = {Acta Hydrochimica Et Hydrobiologica}, month = jun, number = 2, pages = {157-164}, title = {Biodiversity and ecology of species of aquatic oomycetes in the Aue Lake and the River Fulda in Kassel (Hessen)}, url = {/brokenurl#://000229922400007}, volume = 33, year = 2005 } @article{riethmuller2006seasonal, abstract = {We compared the seasonal occurrence of Leptomitus lacteus (Roth) C.

For this purpose, we analysed 42 different water samples of running waters from Hesse and Thuringia and additionally of stagnant waters and of a spring from Hesse. For isolating L. lacteus, the baiting technique was used. The simultaneous limnochemical characterisation of the examined waters resulted in information on the trophic status of the lakes and the water quality classification of some rivers. L. lacteus occurred in all three types of waters examined. Based on the number of samples in which it occurred, L. lacteus seems to prefer rivers rather than stagnant waters. L. lacteus could be isolated during the whole year. Nevertheless, most isolates were obtained in winter. Hence, a preference for growth and propagation in winter is postulated.}, author = {Riethmuller, A. and Grundel, A. and Langer, E.}, interhash = {ee234cb970d3c7041b1685123aa89bbb}, intrahash = {6bcf16a26bbb7cedc641c4387c986768}, journal = {Acta Hydrochimica Et Hydrobiologica}, month = apr, number = {1-2}, pages = {58-66}, title = {The seasonal occurrence of the sewage fungus Leptomitus lacteus (Roth) C.
