Reexamination ofXanthoria persica, X. polycarpoides, X. lobulata gave evidence, that the thalli of these species are devoid of a lower cortex and rhizinae. Therefore, they do not fit the
definition of the genusXanthoria and are transferred toCaloplaca (under the new sectionXanthoriella) asCaloplaca persica, C. polycarpoides, andC. boulyi, respectively. — Details on development, anatomical structure, ecology and distribution are presented.

Cynoglossopsis somaliensis
H. Riedl, sp. nov., is described as a new species of the hitherto monotypic genusCynoglossopsis
Brand which is closest related toCynoglossum L. but has to be included inBoraginoideae-Eritrichieae from the way the nutlets are attached to the gynobasis. 相似文献

The phycobiont ofCatolechia wahlenbergii belongs to a new genus of theChlorococcales. It has mostly ellipsoidal, more rarely spherical cells with one bilobate through-shaped chloroplast and in general alveolar cytoplasm. Reproduction occurs by 2 or 4 autospores as well as by 16 or 32 motionless, small rodlike spores, which are formed and released in the same way as zoospores. They are aplanospores, and their formation apparently is fixed genetically, and not modificatorily, as in other species. 相似文献

The authors studied biological competition between some african snails (Biomphalaria pfeifferi, Bulinus truncatus sericinus, Limnea natalensis) and Helisoma duryi in the laboratory.The results are irregular and less successful than with the closely related species, Biomphalaria glabrata.

Zusammenfassung
Veronica chamaedrys L. subsp.micans M.Fischer, unterscheidet sich vonV. chamaedrys L. subsp.chamaedrys hauptsächlich durch die meist hellgrün gefärbten und im Leben oberseits stets schwach glänzenden Laubblätter, deren Blattrand durchschnittlich mehr (9–11) Zähne aufweist, durch die stets drüsenlose Infloreszenzbehaarung, die kleineren Blüten mit schmäleren Sepalen und hellblau (nicht leuchtend-sattblau) gefärbten Corollen sowie durch die diploide Chromosomenzahl (2 n=16). Sie tritt in der mittleren Bergstufe zusammen mit subsp.chamaedrys auf, ersetzt sie jedoch in der oberen Bergstufe und in der Krummholzstufe an±gleichen Standorten fast vollständig (mit Ausnahme der stark eutrophierten Standorte, die ausschließlich von subsp.chamaedrys besiedelt sind). Die neue Sippe ist bisher nur aus den nordöstlichen Alpen bekannt geworden (vgl. S. 77).
Cytotaxonomy ofveronica chamaedrys L. agg., II.: subsp.micans M.Fischer, a new diploid race
Summary Veronica chamaedrys L. subsp.micans M.Fischer differs fromV. chamaedrys L. subsp.chamaedrys mainly by: leaves bright green, in the living state always slightly but distinctly shining on the upper surface; margins on the average with more (9–11) teeth at each side; indumentum of the inflorescence without any glands; flowers relatively small with bright blue corollas and narrow sepals; chromosome number diploid: 2 n=16. In the upper mountain and subalpine region, where it replaces the common tetraploid subsp.chamaedrys L.; it is known up to now only from the Northeastern Alps (see p. 77).相似文献

Population variability ofOphrys holosericea (Burm. f.)Greut. subsp.holosericea (=O. fuciflora
Crantz subsp.fuciflora) from near Vienna (Austria), and of subsp.maxima (Fleischm.)Greut. andO. cornuta
Steven with intermediates from the Dalmatian island Hvar (Yugoslavia) was analysed and illustrated by scatter diagrams. A hybrid origin of these intermediates is suggested. Aspects of hybridization betweenO. holosericea agg. andO. scolopax agg. are discussed. 相似文献

Zusammenfassung Ein Stamm von Streptomyces olivaceus, Tü 1379, bildet neben den bekannten Bakterienfarbstoffen Prodigiosin C-25 und Metacycloprodigiosin mehrere vermutlich cyclische -Hydroxyacyldecapeptide, hauptsächlich Imacidin B und C, die sich in der Kettenlänge des Acylrestes unterscheiden. Diese Antibiotica werden durch schwache Alkalien schnell verändert, wobei Hydroxyacylpeptide mit unveränderter Aminosäure-Zusammensetzung, aber verringerter biologischer Wirksamkeit, Imacidinsäuren, entstehen, die auch im nativen Rohprodukt enthalten sind. Die Imacidine besitzen ein enges Wirkungsspektrum und hemmen die Zellwandsynthese.

Metabolic products of microorganisms 183. Imacidin, a new peptid antibiotic from Streptomyces olivaceus
Streptomyces olivaceus, strain Tü 1379 produces beside the red dyestuff prodigiosin several closely related hitherto unknown cyclodepsipeptide antibiotics, mainly imacidine B and C and imacidinic acids. The antibiotics affect murein biosynthesis. Only actinomycetes are inhibited.

Varicellaria carneonivea is lichenized withAsterochloris phycobiontica, a new member of theChlorococcales. In the free-living state this species reproduces by zoo- and aplanospores; autospores are lacking. Sporangia develop an internal local thickening of the wall, which marks the later aperture. A group of dictyosomes apparently contributes to the formation of this thickening. Secondary carotenoids dissolved in droplets or irregular masses of oil are deposited around and within the pyrenoid. 相似文献

TheOmphalotaceae fam. nov., which include the generaOmphalotus andLampteromyces, are defined on the basis of characteristic sesquiterpenes and of their ability to cause white-rot. Anatomical and morphological features of the representatives of these genera support the creation of this new family. The occurrence of pigments, typical of theBoletales, and of cyanophilous spores, indicate membership of theOmphalotaceae in the orderBoletales. Relationships to the other families of this order — especially to thePaxillaceae — are discussed. The possible functional significance of fungal metabolites is considered.

Eusynaptomyces benjaminii is described as a new species of the ectoparasiticLaboulbeniales (Ascomycetes). It exists only on two very restricted areas of the body (= position specifity) of its hostEnochrus testaceus (F.) (Coleoptera, Hydrophilidae): on the claws of the right fore-leg and on the lower side of the frontal border of the pronotum. In these two habitatsEu. benjaminii develops two extremely different growth-forms. Male and female hosts are parasitized on somewhat different parts of their body. This can be explained by their mating behaviour. The growth-forms ofEu. benjaminii are so different that one ignorant of the biology of hosts and parasites, might regard them as members of different species or even genera. They are to be interpreted as adaptations of one species to growth positions and mating behaviour of the host. There is no sex-of-host specifity as assumed by certain authors for several species of theLaboulbeniales.

Asperula visianii
Korica is described as a new stenoendemic species from the small Central Dalmatian island of Svetac (near Vis). It differs in several morphological features (which remain constant in cultivation) and in its ecology from the closely relatedA. staliana
Vis., endemic on the nearby island of Bievo. 相似文献
