A New, Commercially Valuable Chanterelle Species, Cantharellus californicus sp. nov., Associated with Live Oak in California, USA

A New, Commercially Valuable Chanterelle Species, Cantharellus californicus sp. nov., Associated with Live Oak in California, USA. The prominent golden chanterelle of California’s oak woodlands is characterized as a new species, Cantharellus californicus sp. nov., using molecular and morphological data. Our observations indicate that it is the largest Cantharellus species in the world, with individual sporocraps commonly weighing 1/2 kilogram (kg) (or 1 pound) or more when mature. Other Cantharellus species in California are compared and evaluated, including their known ectomycorrhizal hosts. The California oak chanterelle is an economically valuable species, and some observations on its commercial harvest are presented.     

Nationalization and Globalization Trends in the Wild Mushroom Commerce of Italy with Emphasis on Porcini (<Emphasis Type="Italic">Boletus edulis</Emphasis> and Allied Species)

Nationalization and Globalization Trends in the Wild Mushroom Commerce of Italy with Emphasis on Porcini ( Boletus edulis and Allied Species). This paper presents an historical overview of wild mushroom commerce in Italy, with a focus on recent trends in the production of porcini (Boletus edulis and closely allied species). Over the past century, two major trends—nationalization and globalization—have been apparent in the wild mushroom commerce of Italy. First, a simplified national mushroom menu has emerged through processes of governmental regulation and culinary fashion, but it has come at the expense of differing, localized mushroom traditions which may suffer under the European Union’s free trade principles. Second, Italy has emerged as a focal point of a global market for a small number of mushroom species—particular porcini. While the name porcini has become synonymous with Italian cuisine, and in spite of a vibrant tradition of recreational mushroom collecting in Italy, most of the porcini commercially available in Italy or exported by Italy are no longer of Italian origin. Porcini and other mushrooms now flow into Italy from all over the world—especially from China and eastern Europe—and are then often exported as “Italian porcini.” This globalization of the wild mushroom trade, while offering significant income to rural producers and processors around the globe, has other effects as well, for example, a kind of national branding as “Italian” of globally-produced products, of which porcini is one, that is in direct opposition to some of the European Union’s rules for regional denominations.

Processi di Nazionalizzazione e Globalizzazione nel Commercio Italiano dei Funghi spontanei, con Particolare Riguardo ai Porcini ( Boletus edulis e Specie Affini). Questo articolo presenta una panoramica storica sul commercio dei funghi spontanei in Italia, con particolare riguardo alle recenti tendenze nella produzione dei porcini (Boletus edulis e specie affini). Nello scorso secolo si sono osservate due tendenze principali—di nazionalizzazione e di globalizzazione—nel commercio dei funghi spontanei in Italia. In primo luogo si è affermata nel territorio nazionale una tradizione limitata al consumo di un numero contenuto di specie, sia per effetto di alcune normative che di mode culinarie, ma ciò è avvenuto a discapito di tradizioni locali più ricche, che potrebbero ulteriormente risentire dei principi per il libero scambio all’interno dell’Unione Europea. In secondo luogo, l’Italia si è posta in evidenza come un punto nodale per il mercato globale di alcune specie fungine, in particolare dei porcini. Nonostante quest’ultimo termine sia tradizionalmente associato alla cucina italiana, e nonostante esista in Italia una vivace e radicata tradizione nella raccolta amatoriale dei funghi, la maggior parte dei porcini ivi commercializzati (allo stato fresco, essiccati o variamente conservati) o esportati verso altri paesi non sono più di origine locale. I porcini e altre specie fungine giungono attualmente in Italia da ogni parte del mondo—in modo particolare dalla Cina e dall’Europa orientale—e sono successivamente spesso esportati come “prodotti Italiani.” Questo processo di globalizzazione del mercato dei funghi spontanei, pur offrendo un significativo introito ai raccoglitori e commercianti rurali su tutto il globo, è responsabile di altri effetti, come per l’appunto una sorta di marchio nazionale “Italiano” su alcuni prodotti di provenienza globale, come per l’appunto i porcini, cosa che contrasta con alcune delle regole dell’Unione Europea in materia di denominazioni regionali.

     

New taxa ofCosmarium Corda (Desmidiaceae) from Karnataka State,India

Six new taxa including two new species (Cosmarium bourrellyi Bongale sp. nov. andC. desikacharyi Bongale sp. nov.) and four new varieties (C. auriculatum var.protrusum Bongale var. nov.,C. pachydermum var.inflatum Bongale var. nov.,C. pseudoconnatum var.tuberculans Bongale var. nov. andC. quadrum var.rotundatum Bongale var. nov.) are reported. Algae were collected from a paddy field at Belgaum.     

共头霉的单孢孢子囊变种

我们从江苏、浙江两省采到的一些样品中分离得到六株毛霉菌种并鉴定为分别属于三个变种的同一个新种,即单孢共头霉原变种(Syncephalastrum monosporum Zheng et al.sp. nov. var. monosporum),单孢共头霉冠囊变种(Syncephalastrum monosporum Zheng et al. var. cristatum Zheng et al. var. nov.),以及单孢共头霉多重生变种(Syncephalastrum monosporum Zheng et al. var. pluriproliferum Zheng et al. var. nov.).它们与共头霉属的唯一已知种总状共头霉(Syncephalastrum racemosum Cohn ex Schroeter)的主要区别在于全部孢子囊都是单孢的小型孢子囊(柱孢囊)而不是像后者一样孢子成单行排列的多袍柱孢囊.我们把这些菌归人共头霉属而没有为它们专门成立一个新属的理由除因它们与总状共头霉有明显的亲缘关系外,主要还因我们认为在不具备其它重要区别特征的情况下,在毛霉目的分类中,无论在科级或属级的水平上,都不应过分强调单孢孢子囊的作用.尽管单孢共头霉是毛霉目内唯一具单孢子柱孢囊的种,我们仍然把它们归入共头霉属内.至于我们为什么要把这六株菌鉴定为一个种的三个变种而不是三个各自独立的种,则是由于我们承认共头霉属的唯一已知种总状共头霉是一个变异性很大的种而并没有把它分成许多不同的种,因此,我们对这个属的另外一个种,即单孢共头霉同样采用较大的种概念.     

Discovery of the Drosophila (Drosophila) robusta species group (Diptera,Drosophilidae) from Southeast Asian tropics,with the descriptions of six new species

Six new species of the Drosophila robusta species group are described from Southeast Asian Islands. Kalimantan and Sunda Islands lie east of Bali, from which Drosophila barobusta sp.nov and D. uncinata sp.nov belong to the lacertosa subgroup, and D. sungaicola sp.nov, D. baliensis sp.nov, D. hitam sp.nov and D. subaquatica sp.nov to the okadai subgroup. The robusta group from Southeast Asian tropics exclusively inhabits streamsides in mountainous highlands with an elevation of more than 600 m from the sea level.     

Systematics of the Gyrosigma balticum complex (Bacillariophyta), including three new species

Three new species in the genus Gyrosigma Hassall (G. caliG. Reid sp. nov., G. gibbyiG. Reid sp. nov. and G. murphyi G. Reid sp. nov) are described. A cladistic analysis on the basis of 10 morphological characters, was undertaken to investigate the interrelationships of these new species within Gyrosigma. As well as ‘standard’ cladistic analysis, which apportions equal weight to all characters, a posteriori differential weighting was also investigated. Pleurosigma subtilis Brébisson is transferred to Gyrosigma, as G. subtile (Brébisson) G. Reid comb. nov., because it is more closely related to other species of Gyrosigma than to Pleurosigma Smith. G. balticum var. californicum Grunow in Cleve and Möller is elevated to specific status [as G. californicum (Grunow in Cleve and Möller) G. Reid stat. nov.], because it does not form a monophyletic group with G. balticum (Ehrenberg) Rabenhorst.     

Neoselachians (Chondrichthyes,Elasmobranchii) from the Lower and lower Upper Cretaceous of north‐eastern Spain

Extensive sampling of several Barremian and Albian–Cenomanian levels across the Aguilón, Oliete and Aliaga subbasins of the Iberian Basin, north‐east Spain, yielded abundant material of new or so far poorly known neoselachians. The faunas consist of 16 different species, five of which represent new species and two new genera: Cantioscyllium brachyplicatum sp. nov. , Platypterix venustulus gen. et sp. nov. , Ptychotrygon pustulata sp. nov. , Ptychotrygon striata sp. nov. and Iberotrygon plagiolophus gen. et sp. nov. In addition, teeth of Heterodontus cf. H. carerens, Lamniformes indet., Pteroscyllium sp., Scyliorhinidae indet., Rhinobatos sp., Spathobatis sp., Belemnobatis sp., Ptychotrygon geyeri, Ptychotrygon sp. and Celtipristis herreroi are described. The new family Ptychotrygonidae is defined. The localities comprise palaeoenvironments ranging from lacustrine and shallow lake to open marine settings. Neoselachians are almost completely absent from continental settings in the Barremian, as a result of prevailing freshwater conditions, but became more abundant in marine strata. The Albian–Cenomanian selachian assemblage is the most profuse and diverse of the three assemblages studied. It is dominated by small, benthic and near‐coastal taxa, for instance Cantioscyllium and Ptychotrygon, and contains several new species, including an endemic batoid, Iberotrygon plagiolophus gen. et sp. nov. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155 , 316–347.     

The diatom flora of the Salton Sea, California

We report on diatom species of the Salton Sea, a highly saline (43 g l^–1) inland lake in California. We identified and photographed all diatom taxa encountered in the phytoplankton and benthos of the Salton Sea and its immediate tributaries. Ninety-four taxa were distinguished based on their morphological features using light- and electron microscopy. In the Salton Sea, there are four general categories of diatom assemblages related to their habitats: (1) A planktonic assemblage composed of Chaetoceros muelleri var. subsalsum, Cyclotella choctawhatcheeana, Cyclotella sp., Cylindrotheca closterium, Pleurosigma ambrosianum, Thalassionema sp.; (2) a benthic assemblage with diatoms that live on the bottom (e.g. genera Caloneis, Diploneis, Entomoneis, Gyrosigma, Plagiotropis, Pleurosigma, Surirella and Tryblionella), or in algal mats (Proschkinia bulnheimii, several species of Navicula and Seminavis gracilenta); (3) an epiphytic community attached to the macroscopic green algae which grow on the rocks and other hard surfaces near shore (e.g. Achnanthes brevipes, Licmophora ehrenbergii, Tabularia parva); and (4) a freshwater assemblage composed of species that get washed in by the rivers and other inflows discharging into the Sea (e.g. Achnanthidium minutissimum, Cocconeis pediculus, Cyclotella atomus, C. scaldensis, Nitzschia elegantula, T. weissflogii). The most striking feature of the phytoplankton is the abundance of species formerly known only from marine environments; this is not surprising given the high salinity and the peculiar history of the lake.     

Coccolithophorids from the west coast of Baja California, Mexico

Studies on coccolithophorids in Mexico are rather scarce, probably due to the use of traditional methods for studying marine phytoplankton (e.g. collection, preservation and analysis). This is the first study of the coccolithophorid flora from west coast of Baja California, Mexico. Bottle samples (4 l) were taken at various depths (5, 25 and 50 m), at fixed stations located on perpendicular transects along the west coast of Baja California, considering three different zones: North, Central and South. A total of 32 samples were studied by optical and scanning electron microscopy, yielding 24 taxa identified (17 species and 5 nominal varieties, plus 2 different varieties). The coccolithophorid assemblages are considered subtropical and coastal (with many cosmopolitan taxa). Emiliania huxleyi and Gephyrocapsa oceanica were the most abundant (relative abundance) and widespread species in the study area. We report 15 new records for the Mexican Pacific. The zonal and vertical distribution of some taxa are briefly discussed, as well as the taxonomy of Rhabdosphaera claviger, Helicosphaera carteri, H. hyalina and related taxa.

NEW MARINE ALGAE FROM THE CENTRAL TROPICAL PACIFIC OCEAN

Three new taxa are described: Dolyella hawaiiensis var. clavata var. nov., Cottoniella triseriata sp. nov., and Taenioma dotyi sp. nov. A modified characterization of the genus Cottoniella is given, and certain critical distinctions between the species are presented. Taenioma dotyi is distinctive in the increased width of the determinate branches resulting from division of the flanking cells.     

Seven new species of Penicillium and a new variety of Penicillium novae-caledoniae Smith

Seven new species of Penicillium Link ex Fries and a new variety of Penicillium novae-caledoniae Smith are described and illustrated. Four of them have been recovered from the air in Madrid, Spain, one from beech leaves litter in a beech forest near Nancy, France, two from sandy soils in Madrid, and one from an andosol in the Spanish Province of Navarra. They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new taxa: Penicillium turolense sp. nov., Penicillium murcianum sp. nov., Penicillium ovetense sp. nov., Penicillium asturianum sp. nov., Penicillium onobense sp. nov., Penicillium castellonense sp. nov., Penicillium aragonense sp. nov., and Penicillium novae-caledoniae Smith, var. album var. nov.     

Description of nine new species of Heliura Butler from South America (Lepidoptera,Erebidae, Arctiinae,Arctiini, Ctenuchina)

Nine new species of the genus Heliura are described from Brazil (H. brasiliana sp. nov., H. olivocolora sp. nov., H. pulcherrima sp. nov., and H. laerteae sp. nov.), Ecuador (H. ecuadoris sp. nov.), Peru (H. flavipennis sp. nov. and H. peruana sp. nov.), and Venezuela (Heliura albiventris sp. nov. and H. juliani sp. nov.). They are illustrated in habitus and genitalia, and their phylogenetic affinities are discussed based on morphological evidence.     

Cyrtocrinids (Echinodermata,Crinoidea) from Upper Jurassic Štramberk‐type limestones in southern Poland

Abstract: A systematic account of highly diverse cyrtocrinid faunules from Upper Jurassic strata of ?tramberk type (Oxfordian–Tithonian) in southern Poland (Polish Carpathians) is presented. Fourteen taxa (Phyllocrinus malbosianus, Ph. stellaris, Ph. sp., Psalidocrinus armatus, Sclerocrinus compressus, S. polonicus sp. nov., Hemicrinus aff. kabanovi, Ancepsicrinus parvus gen. et sp. nov., Tetracrinus baumilleri sp. nov., Eugeniacrinites alexandrowiczi, E. cf. moravicus, E. sp., Eudesicrinus gluchowskii sp. nov. and Hemibrachiocrinus tithonicus sp. nov. are described and illustrated. Representatives of the genus Eudesicrinus, previously recorded only from the Lower Jurassic, are here shown to extend into the uppermost Jurassic. Other cyrtocrinids considered are common in Jurassic/Cretaceous strata across Europe. In the present faunules, isocrinid (Isocrinida), comatulid (Comatulida) and roveacrinid (Roveacrinida sensu Rasmussen, inclusive of Saccocoma) crinoids are associated.
