Eudendrium pocaruquarum, a new species of athecate hydroid referable to the family Eudendriidae, is described from the state of São Paulo, Brazil. The species is very similar to the widespread Eudendrium ramosum (Linnaeus, 1758), differing from it in the smaller size of the large microbasic euryteles. Longstanding problems in the systematics of eudendriid hydroids are noted, and the inadequacies of many early descriptions of species are discussed. The nematocysts provide a supplementary character for discrimination of species of Eudendrium, although information on the cnidome appears to have been sometimes misinterpreted in literature. |

Scaphopods remain poorly known from the type area of the Maastrichtian Stage in northeast Belgium and the southeast Netherlands. At least three species appear to be represented, but incomplete preservation (i.e., lack of shell material) hampers a detailed systematic treatment of most specimens. In museum collections, the name Dentalium nysti Binkhorst van den Binkhorst, 1861 (= D. binkhorsti Pilsbry & Sharp, 1898; non D. nysti d’Orbigny, 1852) is often used rather indiscriminately for both genuine scaphopods and internal moulds of serpulid worm tubes. Here, we describe and illustrate Antalis? binkhorsti, Fissidentalium? sp. 1 and Dentaliidae sp. indet., all of Maastrichtian age, as well as a late Campanian form, Fissidentalium? sp. 2. |

Dothiorella and Spencermartinsia are two botryosphaeriaceous genera with dark 2-celled conidia and found in parasitic, saprophytic or endophytic association with various woody host plants. Based on ITS and EF1-α sequence data and morphology, eight new species are described from Iran, New Zealand, Portugal and Spain. Of these, five species are placed in Dothiorella, namely D. iranica, D. parva, D. prunicola, D. sempervirentis and D. striata, and three species belong to Spencermartinsia named as S. citricola, S. mangiferae and S. plurivora. An identification key to the species of each genus is provided. |

Plectosphaerella cucumerina, most frequently encountered in its Plectosporium state, is well known as a pathogen of several plant species causing fruit, root and collar rot, and collapse. It is considered to pose a serious threat to melon (Cucumis melo) production in Italy. In the present study, an intensive sampling of diseased cucurbits as well as tomato and bell pepper was done and the fungal pathogens present on them were isolated. Phylogenetic relationships of the isolates were determined through a study of ribosomal RNA gene sequences (ITS cluster and D1/D2 domain of the 28S rRNA gene). Combining morphological, culture and molecular data, six species were distinguished. One of these (Pa. cucumerina) is already known. Four new species are described as... |

The three closely related genera Aleurites J. R. Forst. & G. Forst., Reutealis Airy Shaw and Vernicia Lour., together constituting the subtribe Aleuritinae of the tribe Aleuritideae (Euphorbiaceae subfamily Crotonoideae), are revised. Originally included in Aleurites, Reutealis and Vernicia are considered generically distinct on account of differences in the indumentum, leaf base, inflorescences, number of stamens and fruit type. This distinction has also been confirmed by a recent phylogenetic analysis. Aleurites (2 species) differs from Reutealis and Vernicia by the more numerous stamens arranged in 4 rather than in 2 whorls, and the indehiscent fruits. The monotypic genus Reutealis can easily be distinguished from Aleurites and Vernicia by its... |

Pollen and orbicule ontogeny in representatives of three genera of Dioscoreales—Narthecium ossifragum Huds. (Nartheciaceae), Tacca artocarpifolia Seem. and Tacca chantrieri Andre´ (Dioscoreaceae), and Dioscorea communis (L.) Caddick & Wilkin (Dioscoreaceae)—is described and illustrated using LM, SEM, and TEM. The main difference is in microsporogenesis, which is successive in Narthecium Huds. and simultaneous in Tacca J.R. & G. Forst. and Dioscorea L. This is reflected in the tetrad configuration but not in the apertures: Narthecium and Tacca are monosulcate, while Dioscorea has two equatorial apertures. Other features of pollen development are similar in all three genera. Exine development starts at the proximal pole, and during the tetrad stage,... |

Anthracnose caused by Colletotrichum species is a serious disease of more than 30 plant genera. Several Colletotrichum species have been reported to infect chili in different countries. Although China is the largest chiliproducing country, little is known about the species that have been infecting chili locally. Therefore, we collected samples of diseased chili from 29 provinces of China, from which 1285 strains were isolated. The morphological characters of all strains were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT, CAL, CHS-1, GAPDH, TUB2, and HIS3) were performed on selected representative strains. Fifteen Colletotrichum species were identified, with C. fioriniae, C. fructicola, C. gloeosporioides, C. scovillei, and C.... |

Species of Leucadendron, Leucospermum and Protea (Proteaceae) are in high demand for the international floriculture market due to their brightly coloured and textured flowers or bracts. Fungal pathogens, however, create a serious problem in cultivating flawless blooms. The aim of the present study was to characterise several of these pathogens using morphology, culture characteristics, and DNA sequence data of the rRNA-ITS and LSU genes. In some cases additional genes such as TEF 1-α and CHS were also sequenced. Based on the results of this study, several novel species and genera are described. Brunneosphaerella leaf blight is shown to be caused by three species, namely B. jonkershoekensis on Protea repens, B. nitidae sp. nov. on Protea nitida and B.... |

Stromata of Trichoderma species having green ascospores were collected in various regions of China. Based on morphology of the sexual and asexual morph, culture characteristics, and sequence analyses of rpb2 and tef1 genes, 17 species with green ascospores were identified. Among them, Trichoderma rosulatum, T. rufobrunneum and T. stipitatum are described as new species, and seven other species are reported for the first time from China. Trichoderma rosulatum produces small bright yellow or pale greenish stromata with dense dark green ostioles and gliocladium-like conidiophores, shows a close relationship to T. thelephoricola, and belongs to the Chlorospora clade. Trichoderma rufobrunneum, which typically forms reddish brown stromata, is recognised as a... |

The paper presents the results of a general survey of the hydroid fauna of the coastal region of the São Sebastião Channel, São Paulo State, Brazil. Intensive collecting in the intertidal and infralittoral zones, from 1984 to 1992, led to the discovery of many species, some of which are small and inconspicuous. Out of 59 species of hydroids (17 athecate and 42 thecate) described and illustrated, three are new records for the Atlantic Ocean, six for the western South Atlantic, and 21 for the Brazilian coast. The medusa stage of Asyncoryne ryniensis and the cnidome of 24 species are described for the first time. The paper also contains a synopsis of the hydroids recorded from the Brazilian coast, the list now including 107 species. Pseudostenotele... |

Despite being diverse globally, Miocene echinoids are poorly known from Jamaica. Moderately diverse echinoids and other echinoderms have been identified mainly from fragmentary specimens collected from chalks and mass-flow deposits of the Lower Miocene Montpelier Formation, White Limestone Group, near Duncans, parish of Trelawny. This locality has yielded the most diverse association of fossil echinoderms known from the Miocene of Jamaica, including at least ten species in four classes. This fauna is comprised of the isocrinid crinoids Neocrinus sp. cf. N. decorus (Wyville Thomson) and Isocrinus sp.; the ophiuroid Ophiomusium? sp.; the asteroids Astropecten? spp.; and the echinoids Prionocidaris? sp., Histocidaris sp., Echinometra sp. cf. E. lucunter... |

The present paper constitutes an introduction to taxonomic methodology. After an analysis of taxonomic practice, and a brief survey of kinds of attributes, the paper deals with observation, description, comparison, arrangement and classification, hypothesis construction, deduction, model, experiment, abstraction, and synthesis. The methodological aspects of the species-concept and of biological classification are dealt with in two final sections. |
