A revision of the genus Nomocharis Franchet

SEALY, J. R, 1983. A revision of the genus Nomocharis Franchet. A taxonomic revision of the genus Nomocharis Franchet is presented, recognizing seven species. Notes are given on the species and hybrids in cultivation. A key for identification of the species and an index to specific epithets, including synonyms, are given, together with species excluded from the genus. Herbarium specimens are cited.     

Two new species of Acervus (Pezizales) with a key to species of the genus

Studies on the genus Acervus from China are reviewed briefly. Six of the seven known species of the genus are currently recorded in this country. Acervus beijingense and A. changchunense are described as new based on morphological features and molecular data, and A. flavidus with minor emendation is added to the Chinese fungus flora. Phylogenetic relationships among four of the seven species of the genus are investigated based on the 28S rDNA sequence analysis. Species of the genus formed a single clade with high bootstrap support. The sequences of A. epispartius forma epispartius and that of A. flavidus obtained from materials in different geographical regions together formed a group with 100% bootstrap support. Ascospore size and shape are important criteria in the taxonomy of the genus and are phylogenetically informative. A dichotomous key to all described species of the genus is provided.

A revision of the genus Labidochromis (Teleostei: Cichlidae) from Lake Malawi

The diagnosis of the genus Labidochromis is revised to include species with bicuspid outer teeth. Sixteen species, of which 13 are new, are described and illustrated and the validity of five others is discussed. The interrelationships between members of the genus and the relationship of the genus to other genera are discussed. No clearly defined sister group to the genus has been found either within or outside the Lake Malawi cichlid species flock. A key based on the coloration of known species is included.     

On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.     

History and current taxonomic status of genus Agrobacterium

The genus Agrobacterium was created a century ago by Conn who included it in the family Rhizobiaceae together with the genus Rhizobium. Initially, the genus Agrobacterium contained the non-pathogenic species Agrobacterium radiobacter and the plant pathogenic species Agrobacterium tumefaciens and Agrobacterium rhizogenes. At the end of the past century two new pathogenic species, Agrobacterium rubi and Agrobacterium vitis, were added to the genus. Already in the present century these species plus Agrobacterium larrymoorei were reclassified into genus Rhizobium. This reclassification was controversial and for a time both genus names were used when new species were described. Few years ago, after a taxonomic revision based on genomic data, the old species A. rhizogenes was maintained in the genus Rhizobium, the old species A. vitis was transferred to the genus Allorhizobium and several Rhizobium species were transferred to the genus Agrobacterium, which currently contains 14 species including the old species A. radiobacter, A. tumefaciens, A. rubi and A. larrymoorei. Most of these species are able to produce tumours in different plants, nevertheless the genus Agrobacterium also encompasses non-pathogenic species, one species able to nodulate legumes and one human pathogenic species. Taking into account that the species affiliations to five Agrobacterium genomospecies have not been determined yet, an increase in the number of species within this genus is expected in the near future.     

中国果疣衣属地衣的研究

果疣衣属地衣系子囊菌门Ascomycota,子囊菌纲Ascomycetes,茶渍衣亚纲Lecanoromycetidae,鸡皮衣目Pertusariales,鸡皮衣科Pertusariaceae的成员。由于粉色果疣衣Varicellariarhodocarpa在中国的首次发现,使中国地衣区系中新增添了一个属:果疣衣属Varicellaria。该属迄今已知仅含三种,即粉芽果疣衣V.kemensis,八孢果疣衣V.carneonivea及粉色果疣衣V.rhodocarpa。果疣衣属为壳状地衣,地衣体微薄,膜质;子囊盘茶渍型,单个或数个聚生于瘤状果疣中;类侧丝多分枝并呈网状缠绕;子囊内含单孢或八孢;子囊孢子大型(长度为200~400mm),双胞,无色透明,椭圆形;孢子壁厚达27mm;与鸡皮衣属不同之处在于前者子囊内含双胞孢子,后者子囊内含单胞孢子。由于该属在中国是首次被发现,为了进一步的研究,文中还提供了该属迄今已知的全部三种的分种检索表。粉色果疣衣以其地衣体基本无粉芽和遇Pd呈负反应而区别于粉芽果疣衣,以子囊内含单孢而区别于八孢果疣衣。通过薄板层析法首次从该种髓部检测出茶渍衣酸。其地理成分为北极高山种,主要分布于欧洲的挪威、瑞典、芬兰、阿尔卑斯山脉,喀尔巴阡山脉、苏格兰以及北美洲;在亚洲迄今只见于日本与中国。     

Four new species of southern African octocorals (Cnidaria: Alcyonacea), with a further diagnostic revision of the genus Alcyonium Linnaeus, 1758

Four new species of soft corals are described from the shallow sublittoral of southern Africa. Three of the species are referable to the genus Alcyonium Linnaeus, 1758 (family Alcyoniidae), although two of these possess growth forms that are atypical for most members of the genus. A revised diagnosis of the genus is therefore included. A new species in the family Nephtheidae is also described, this being referable to the genus Capnella Gray, 1869. All four species are from the region between the Cape of Good Hope Peninsula and the eastern Cape Province of South Africa. This is the region of the Agulhas Bank, an austroafrican biogeographic region that shows a high incidence of endemism with respect to the marine invertebrate fauna.
