Summary

A key to the British species of the genus Suillus based on habitat, microscopic and macroscopic characters is discussed. Some species as yet unrecorded for the British Isles are included for completeness. Also included in the key are the only W. European member of Fuscoboletinus, the single British species of Bolentis, and two Xerocomus spp., X. badius and X. rubinus, both of which are superficially similar (in some characters) to members of the genus Suillus. The genera Chalciporus and Fuscoboletinus are reviewed and the taxonomic status of Boletus grevillei is discussed in detail.  相似文献

Summary

A key to those British boletes which have been attributed to the genus Xerocomus, based on habitat, microscopic and macroscopic characters is proposed. Two taxa included or re-introduced into the British list based on field observations, are Boletus conifer arum and B. spadiceus. They may have been overlooked previously or confused with far commoner taxa, especially those of the Boletus chrysenteron-subtomentosus complex. Some extra-limital and little known species have been keyed out for completeness ; they include Boletus amarellus, B. armeniacus, B. badiorufus, B. lanatus, B. striaepes, B. truncatus, and B. tumidus. Also included are boleti which may be confused with certain members of this group, as are B. dupainii, B. lignicola and B. porosporus each of which is based on a single British collection. Boletus versicolor and its satellites are distinguished from each other in the key as are the dark green forms of B. chrysenteron.  相似文献

Summary

A key to the species of the genus Boletus sensu stricto based on habitat, microscopic and macroscopic characters is proposed. Three extra-limital species, as yet unrecorded from the British Isles, B. torosus, B. lupinus Krombh. and B. lupinus s. Bres., are included in the key in the hope that they may appear in future. They may have been overlooked previously or confused with far commoner forms, especially B. luridus, to which many quite distinct species have previously been referred. Also included in the key are three boletes not considered taxonomically to belong to this genus in its strict sense, although in some ways they are superficially similar. The only West European species of Tylopilus is keyed out and its taxonomic position considered. Boletus rubellus Krombh. placed by some American authors in Boletus sensu stricto is also discussed.  相似文献

Summary

A key to members of the genera Chroogomphus, Gomphidius, Paxillus and Phylloporus based on habitat, microscopic and macroscopic characters is proposed. One extra-limital species of the first genus, C. ochraceus, and one of the penultimate genus, P. vernails, are included because they may be recorded in the future. The taxon, G. gracilis, often taken as a variety of a far commoner species, is keyed out so that future records will allow its status in the British flora to be ascertained.  相似文献

The chemotaxonomic findings relating to the generaBoletinus, Suillus, Gastroboletus, Gomphidius, andChroogomphus are summarized and discussed, using published data as well as our own hitherto unpublished evidence of pigments and chromogens. The study confirms repeatedly made claims that these genera are closely related. In addition to the presence of pigments which are typical for most members of theBoletales (e.g., pulvinic acid derivatives, terphenyl quinones, cyclopentenones), prenylated phenols and quinones can also be constantly detected here (with the exception ofBoletinus), just as inRhizopogon. Accordingly,Suillus is more closely related to theGomphidiaceae andRhizopogonaceae than to the remaining boletes. It is therefore necessary to establish a new family (Suillaceae which includeBoletinus, Suillus, andGastrosuillus) and a new suborder (Suillineae which includeSuillaceae, Gomphidiaceae, andRhizopogonaceae) within theBoletales.

A new genus belonging to the braconid wasp subfamily Doryctinae, Kauriphanes n. gen. (type species K. khalaimi n. sp.), is described from New Zealand. This genus is placed within the doryctine subtribe Caenophanina. The extent of this subtribe is discussed and the phylogenetic relationships of three of its genera were investigated using one mitochondrial and one nuclear DNA sequence markers. Similar to previous studies, the Bayesian analyses performed significantly support a clade with the included members of Caenophanina as a sister group of a clade with the examined species of Spathiini sensu stricto. The placement of the Caenophanini within Doryctini, however, is left pendant to further exhaustive phylogenetic studies. A key to genera and subgenera belonging to Caenophanina is given.  相似文献

Abstract

Three new genera—Austroclima, Mauiulus, and Cryophlebia—are established for species of Leptophlebiidae from New Zealand. The following new combinations are included: Austroclima sepia (Phillips) and Cryophlebia aucklandensis (Peters). Atalophlebioides sepia is redescribed as Austroclima sepia and a neotype is designated. Two new species, Austroclima jollyae and Mauiulus luma, are described. All life stages are described, and the relationships of each genus are discussed. Keys are given to male and female imagos, subimagos, and nymphs of each species, and to all New Zealand genera with species previously placed in Atalophlebioides.  相似文献

Two new genera and three new species of Lycoperdininae (Coleoptera: Endomychidae) from South America, are described and illustrated based on adults: Hylaperdina n. g., along with H. brevicornis n. sp. from Ecuador and H. costariciensis n. sp. from Costa Rica, and Chileanus n. g., along with C. talca n. sp. from Chile. Their most likely placement within the Lycoperdininae is discussed. A key to genera of the neotropical Lycoperdininae is provided.  相似文献

Abstract

Plagiochila britannica is described as a new species. It differs from P. porelloides and P. asplenioides in many characters, especially its often more narrowly oval leaves with a more variable, often truncate to bilobed apex and larger cells, its wider antical stem cells and its diploid chromosome number. Differences from P. arctica var intermedia include its more variable leaf apex, generally more dentate leaves often with longer teeth, the greater maximum size of its leaf cells and its wider antical stem cells. Male and female inflorescences and sporophytes are known in P. britannica, which favours base-rich substrata and has been found in Wales, N. England, Scotland and N. Ireland. A key to the nine species of Plagiochila in the British Isles is included.  相似文献

Abstract: Since the brachiopod Order Lingulida has been greatly revised in recent years, with particular emphasis on Cambrian and Ordovician genera, many well‐established Silurian linguloid species from the British Isles have been left without an appropriate genus in which to place them. This is rectified here by allocating the various species, mostly erected in the nineteenth or early twentieth centuries, to a variety of genera which have been mainly erected within the last forty years. Two new genera are erected, Mergliella, with type species Lingula bechei Davidson, 1866 , and Striatilingula, with type species Lingula? striata J. de C. Sowerby, 1839 .  相似文献

Eleven species of British Hydropsychidae are listed and characterised. The name H.siltalai Döhler 1963 is introduced and the identity of H.insta-bilis and H.fuhipes is discussed. A key to the adult males is given together with a key to the larvae with the exceptions of H.saxonica, H.exocellata, H.guttata. Notes on the distribution of the species are included.  相似文献
