Cordyceps was characterized by the production of well- developed often stipitate stromata and an ecology as a pathogen of arthropods and Elaphomyces with infrageneric classifications emphasizing arrangement of perithecia, ascospore morphology and host affiliation. To refine the classification of Cordyceps and the Clavicipitaceae, the phylogenetic relationships of 162 taxa were estimated based on analyses consisting of five to seven loci, including the nuclear ribosomal small and large subunits (nrSSU and nrLSU), the elongation factor 1α (tef1), the largest and the second largest subunits of RNA polymerase ІІ (rpb1 and rpb2), β-tubulin (tub), and mitochondrial ATP6 (atp6). Our results strongly support the existence of three clavicipitaceous clades and reject the monophyly of both Cordyceps and Clavicipitaceae. Most diagnostic characters used in current classifications of Cordyceps (e.g., arrangement of perithecia, ascospore fragmentation, etc.) were not supported as being phylogenetically informative; the characters that were most consistent with the phylogeny were texture, pigmentation and morphology of stromata. Therefore, we revise the taxonomy of Cordyceps and the Clavicipitaceae to be consistent with the multi-gene phylogeny. The family Cordycipitaceae is validated based on the type of Cordyceps, C. militaris, and includes most Cordyceps species that possess brightly coloured, fleshy stromata. The new family Ophiocordycipitaceae is proposed based on Ophiocordyceps Petch, which we emend. The majority of species in this family produce darkly pigmented, tough to pliant stromata that often possess aperithecial apices. The new genus Elaphocordyceps is proposed for a subclade of the Ophiocordycipitaceae, which includes all species of Cordyceps that parasitize the fungal genus Elaphomyces and some closely related species that parasitize arthropods. The family Clavicipitaceae s. s. is emended and includes the core clade of grass symbionts (e.g., Balansia, Claviceps, Epichloë, etc.), and the entomopathogenic genus Hypocrella and relatives. In addition, the new genus Metacordyceps is proposed for Cordyceps species that are closely related to the grass symbionts in the Clavicipitaceae s. s. Metacordyceps includes teleomorphs linked to Metarhizium and other closely related anamorphs. Two new species are described, and lists of accepted names for species in Cordyceps, Elaphocordyceps, Metacordyceps and Ophiocordyceps are provided.

  • The Case of Centaurea Stoebe (Spotted Knapweed)
    Endophytic fungi as a biodiversity hotspot: the case of Centaurea stoebe (spotted knapweed) Alexey Shipunov Department of Forest Resources University of Idaho Spotted knapweed Spotted knapweed (Centaurea stoebe L., also known as C. maculosa, C. micrantha, C. biebersteinii) is a noxious, invasive plant which was introduced into North America from Eurasia in 1890s. Plant fungal endophytes • Grow inside plant, but do not cause any symptoms • Cryptic symbionts, inhabiting all plants • Play lots of different roles, include host tolerance to stressful conditions, plant defense, plant growth, and plant community biodiversity • One example of the economic importance of endophytes is taxol, well-known anticancer drug, which is not a product of Taxus brevifolia (yew) tree, but of its endophyte Taxomyces andreana Anamorphs and teleomorphs More than 1/3 of fungi do not normally express any sexual characters. They are anamorphs. Sometimes, some anamorphic fungi develop into sexual teleomorphs which have “more morphology” and can be properly classified. Before molecular era, all anamorphic fungi have been treated as Alternaria (anamorph, above), “Deuteromycota”. and Lewia (teleomorph, below) Most of knapweed endophytes are are the same organism. anamorphic ascomycetes. BLAST search usually reveals mixed lists of ana- and teleomorph names Pleomorphic fungi (with variable anamorph/teleomorph relationships) are one of the most painful problem for fungal taxonomy. The weakness of morphology From Jeewon et al. (2003), and Hu et al. (2007) Pestalotiopsis example: morphology chosen as the only identification tool leads to highly tangled molecular tree. “Identify, then sequence” does not work for novel isolates. Thus, the identification of fungi depends on either high level of expertise, or on proper barcoding.

HODGE1 1 Department of Plant Pathology, Cornell University, 334 Plant Science Building, Ithaca, New York 14853, USA. 2 National Center for Biotechnology Information, National Institutes of Health, Bethesda, Maryland 20894, USA. E-mail : [email protected] Received 4 April 2005; accepted 19 July 2005. Two specimens of a new species of Hypocrella with large stromata were collected in Bolivia and Costa Rica. The morphology of the new species, H. macrostroma sp. nov., was compared with that of other species with large stromata, i.e. H. africana, H. gaertneriana, and H. schizostachyi. In addition, phylogenetic analyses of partial sequences from three genes, large subunit nuclear ribosomal DNA (LSU), translation elongation factor 1-a (EF1-a), and RNA polymerase II subunit 1 (RPB1), were conducted to determine the relationships of the new species to other species of Hypocrella/ Aschersonia. Phylogenetic analyses show that H. macrostroma belongs to a strongly supported clade that includes H. africana, H. schizostachyi, and Aschersonia insperata, whereas other Hypocrella species belong to two sister clades. Hypocrella macrostroma is described and illustrated, and a lectotype is designated for H. gaertneriana. INTRODUCTION have been linked to teleomorphs.

  • A Faunal Survey of the Elateroidea of Montana by Catherine Elaine
    A faunal survey of the elateroidea of Montana by Catherine Elaine Seibert A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Catherine Elaine Seibert (1993) Abstract: The beetle family Elateridae is a large and taxonomically difficult group of insects that includes many economically important species of cultivated crops. Elaterid larvae, or wireworms, have a history of damaging small grains in Montana. Although chemical seed treatments have controlled wireworm damage since the early 1950's, it is- highly probable that their availability will become limited, if not completely unavailable, in the near future. In that event, information about Montana's elaterid fauna, particularity which species are present and where, will be necessary for renewed research efforts directed at wireworm management. A faunal survey of the superfamily Elateroidea, including the Elateridae and three closely related families, was undertaken to determine the species composition and distribution in Montana. Because elateroid larvae are difficult to collect and identify, the survey concentrated exclusively on adult beetles. This effort involved both the collection of Montana elateroids from the field and extensive borrowing of the same from museum sources. Results from the survey identified one artematopid, 152 elaterid, six throscid, and seven eucnemid species from Montana. County distributions for each species were mapped. In addition, dichotomous keys, and taxonomic and biological information, were compiled for various taxa. Species of potential economic importance were also noted, along with their host plants. Although the knowledge of the superfamily' has been improved significantly, it is not complete.

However, it has been shown that after artificial inoculation, C. purpurea can grow and form sclerotia on stem meristems (Lewis, 1956) so that there is a capacity for epiphytic and endophytic growth. C. phalaridis, an Australian endemite, colonizes whole plants of pooid hosts in a way similar to Epichloë and it forms sclerotia in all florets of the infected plant, rendering it sterile (Walker, 1957; 1970). Until now, about 45 teleomorph species of Claviceps have been described, but presumably many species may exist only in anamorphic (sphacelial) stage and therefore go unnoticed. Although C. purpurea is type species for the genus, it is in many aspects untypical, because most Claviceps species originate from tropical regions, colonize panicoid grasses, produce macroconidia and microconidia in their sphacelial stage and are able of microcyclic conidiation from macroconidia. Species on panicoid hosts with monogeneric to polygeneric host ranges predominate. 329 2. PHYLOGENETIC TREE We compared sequences of ITS1-5.8S-ITS2 rDNA region for 19 species of Claviceps, Database sequences of Myrothecium atroviride (AJ302002) (outgroup from Bionectriaceae), Epichloe amarillans (L07141), Atkinsonella hypoxylon (U57405) and Myriogenospora atramentosa (U57407) were included to root the tree among other related genera.

  • Ascomycota, Hypocreales, Clavicipitaceae), and Their Aschersonia-Like Anamorphs in the Neotropics
    available online at www.studiesinmycology.org STUDIE S IN MYCOLOGY 60: 1–66. 2008. doi:10.3114/sim.2008.60.01 A monograph of the entomopathogenic genera Hypocrella, Moelleriella, and Samuelsia gen. nov. (Ascomycota, Hypocreales, Clavicipitaceae), and their aschersonia-like anamorphs in the Neotropics P. Chaverri1, M. Liu2 and K.T.

(anamorph Aschersonia), Moelleriella (anamorph aschersonia-like), and Samuelsia gen. nov (anamorph aschersonia-like). Species of Hypocrella, Moelleriella, and Samuelsia are pathogens of scale insects (Coccidae and Lecaniidae, Homoptera) and whiteflies (Aleyrodidae, Homoptera) and are common in tropical regions. Phylogenetic analyses of DNA sequences from nuclear ribosomal large subunit (28S), translation elongation factor 1-α (TEF 1-α), and RNA polymerase II subunit 1 (RPB1) and analyses of multiple morphological characters demonstrate that the three segregated genera can be distinguished by the disarticulation of the ascospores and shape and size of conidia. Moelleriella has filiform multi-septate ascospores that disarticulate at the septa within the ascus and aschersonia-like anamorphs with fusoid conidia. Hypocrella s. str. has filiform to long- fusiform ascospores that do not disarticulate and Aschersonia s.

During this time we have continually emphasized the importance of using the best quality certified organically cultivated and sustainably-wildcrafted herbs to produce our herbal healthcare products. This is why we created the “Pharm Farm” – our certified organic herb farm, and the “Plant Plant” – our modern, FDA-audited production facility. It is here that we integrate the centuries-old, time-proven knowledge and wisdom of traditional herbal medicine with the herbal sciences and technology of the 21st Century. Equally important, Herb Pharm has taken a leadership role in social and environmental responsibility through projects like our use of the Blue Sky renewable energy program, our farm’s streams and Supporting America’s Health creeks conservation program, and the Botanical Sanctuary program Since 1979 whereby we research and develop practical methods for the conser- vation and organic cultivation of endangered wild medicinal herbs.
