  • The Phylogeny of Plant and Animal Pathogens in the Ascomycota
    Physiological and Molecular Plant Pathology (2001) 59, 165±187 doi:10.1006/pmpp.2001.0355, available online at http://www.idealibrary.com on MINI-REVIEW The phylogeny of plant and animal pathogens in the Ascomycota MARY L. BERBEE* Department of Botany, University of British Columbia, 6270 University Blvd, Vancouver, BC V6T 1Z4, Canada (Accepted for publication August 2001) What makes a fungus pathogenic? In this review, phylogenetic inference is used to speculate on the evolution of plant and animal pathogens in the fungal Phylum Ascomycota. A phylogeny is presented using 297 18S ribosomal DNA sequences from GenBank and it is shown that most known plant pathogens are concentrated in four classes in the Ascomycota. Animal pathogens are also concentrated, but in two ascomycete classes that contain few, if any, plant pathogens. Rather than appearing as a constant character of a class, the ability to cause disease in plants and animals was gained and lost repeatedly. The genes that code for some traits involved in pathogenicity or virulence have been cloned and characterized, and so the evolutionary relationships of a few of the genes for enzymes and toxins known to play roles in diseases were explored. In general, these genes are too narrowly distributed and too recent in origin to explain the broad patterns of origin of pathogens. Co-evolution could potentially be part of an explanation for phylogenetic patterns of pathogenesis. Robust phylogenies not only of the fungi, but also of host plants and animals are becoming available, allowing for critical analysis of the nature of co-evolutionary warfare. Host animals, particularly human hosts have had little obvious eect on fungal evolution and most cases of fungal disease in humans appear to represent an evolutionary dead end for the fungus.

G~tzsche Lagarasi 2, 700 Egilsstaoir, Iceland and Institut for Sporeplanter, 0ster-Farirnagsgade 2D, 1353 Copenhagen K, Denmark ABSTRACT: Sixteen species of, Helotiales and Pezizales (Discomy­ cetes) are recorded, whereof 9 species are new to the Icelandic flora: Lachnellula suecica. Ciboria polygoni, Peziza cf. cerea, Peziza fimeti. Peziza granulosa. Geopora sp.. Melastiza eha teri, Otide8 cf. alutacea and T8rzetta spurcata. HELOTIALES Helotiaceae ASCOCORYNE SARCOIDES (Jacq.) Groves & Wils. The species was reported by ROSTRUP (1903, p.313) under the name Coryne sarcoides (Jacq.) Tul., from Halssk6gur in N-Ice­ land, based on a specimen collected by 6lafur Daviosson. It has been found many times in the Public Park in Akureyri (AMNH 199, 9958), growing on stumps of different trees, mainly Betula and Sorbus spp., also in Arnarh6ll near Akureyri, in a garden. In SW-Iceland it has been found by Eirikur Jensson in Fossvogur 1988, and in Vifilsstaoahlio near Hafnarfjorour 1978. In the East it has been collected in the forests of Egilsstaoir and Hallormsstaour in 1987-1988 (AMNH 11642, 11856). The growing season is from late August to October. Since the species is rarely found in the ascus-state, it can­ not be ascertained whether A. cylichnum might also be present in the material or not. Hyaloscyphaceae HYMENOSCYPHUS cf. CALYCULUS (Sow.)

  • Two New Species of Discomycetes (Order Pezizales) from Graubiinden, Switzerland
    Arctic and alpine Mycology 3. Bibl. Mycol. 150: 17-22. © J. Cramer in der Gebriider Bomtraeger Verlagsbuchhandlung, Berlin-Stuttgart, 1993. Two new species of Discomycetes (order Pezizales) from Graubiinden, Switzerland Henry Dissing Botanical Institute, Department of Mycology and Phycology, University of Copenhagen, 0ster Farimagsgade 2D, DK-1353 Copenhagen K, Denmark Helvetia pulchra and Melastiza tetraspora are described as new species. H. pulchra is a mem• ber of section Macropus. M. tetraspora is compared with the presumably closely related Melastiza chateri. Additional keywords: Ascomycetes, taxonomy, scanning electron microscopy. About 20 alpine and subalpine localities in Graubiinden, Switzerland, were studied in the period of August-September in 1979, 1982 and 1984. A total of 120 species of Discomycetes (order Pezizales), of which ten are new to sci• ence, were collected. Two new species, viz., Chalazion helveticum and Smardaea purpurea, were published by Dissing (1980,1984). In this paper two new soil inhabiting species from Graubiinden, Melastiza tetraspora (family Pyronemataceae) and Helvetia pulchra (family Helvellaceae, section Macropus) are described and ecological data on both species are presented. Material and methods Notes on habit and habitat were taken in Graubiinden, based on fresh mate• rial. Coverslips for SEM microscopy were prepared from fresh material of M. tetraspora and M. chateri. Detailed studies of microscopic characters were performed on dried material revived in tap water overnight. For histology, the revived material was further fixed in 2.5 % glutaraldehyde and treated according to Dissing & Sivertsen (1988). Sections 2-3 um thick were cut on a Reichert-Jung 2050 Supercut microtome. SEM photos were obtained on a Philips Scanning Microscope after coating with gold-palladium alloy.

  • Two New Genus Records for Turkish Mycota
    MYCOTAXON Volume 111, pp. 477–480 January–March 2010 Two new genus records for Turkish mycota Yusuf Uzun1, Kenan Demirel1, Abdullah Kaya2* & Fahrettin Gücin3 *[email protected] 1Yüzüncü Yıl University, Science & Arts Faculty TR 65080, Van Turkey 2Adıyaman University, Education Faculty TR 02040, Adıyaman Turkey 3Fatih University Science & Arts Faculty TR 34500, Istanbul Turkey Abstract — The genera Geopyxis (Pyronemataceae) and Asterophora (Lyophyllaceae) are recorded from Turkey for the first time, based on collections of Geopyxis carbonaria and Asterophora lycoperdoides. Short descriptions and photographs of the taxa are provided. Key words —Ascomycota, Basidiomycota, biodiversity, macrofungi Introduction Geopyxis carbonaria (Pyronemataceae) is an abundant post-fire discomycete in coniferous forests. This fleshy mushroom has a complex life cycle and is mycorrhizal on deep roots of members of the Pinaceae, and fruits only when the trees die (Vrålstad et al. 1998). Since it often fruits prolifically after wildfires, it has also been considered to be a possible indicator of imminent morel fruiting (Obst & Brown 2000). Asterophora lycoperdoides (Lyophyllaceae) is a relatively rare basidiomycete that parasitizes other mushrooms in the family Russulaceae, especially Russula nigricans and Russula densifolia. It usually fruits after the host has blackened and begun to decay (Kuo 2006). The fungus generally reproduces asexually by brown powdery chlamydospores formed on the cap surface; its gills, which are often absent or deformed, produce sexual basidiospores only infrequently (Roody 2003). According to checklists (Sesli & Denchev 2009) and recently published data (Solak et al. 2009, Kaya 2009), neither of the above taxa have previously been recorded from Turkey. The study aims to contribute to the macromycota of Turkey.

  • A Monograph of Otidea (Pyronemataceae, Pezizomycetes)
    Persoonia 35, 2015: 166–229 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE http://dx.doi.org/10.3767/003158515X688000 A monograph of Otidea (Pyronemataceae, Pezizomycetes) I. Olariaga1, N. Van Vooren2, M. Carbone3, K. Hansen1 Key words Abstract The easily recognised genus Otidea is subjected to numerous problems in species identification. A number of old names have undergone various interpretations, materials from different continents have not been compared and Flavoscypha misidentifications occur commonly. In this context, Otidea is monographed, based on our multiple gene phylogenies ITS assessing species boundaries and comparative morphological characters (see Hansen & Olariaga 2015). All names ITS1 minisatellites combined in or synonymised with Otidea are dealt with. Thirty-three species are treated, with full descriptions and LSU colour illustrations provided for 25 of these. Five new species are described, viz. O. borealis, O. brunneo parva, O. ore- Otideopsis gonensis, O. pseudoleporina and O. subformicarum. Otidea cantharella var. minor and O. onotica var. brevispora resinous exudates are elevated to species rank. Otideopsis kaushalii is combined in the genus Otidea. A key to the species of Otidea is given. An LSU dataset containing 167 sequences (with 44 newly generated in this study) is analysed to place collections and determine whether the named Otidea sequences in GenBank were identified correctly. Fourty-nine new ITS sequences were generated in this study. The ITS region is too variable to align across Otidea, but had low intraspecific variation and it aided in species identifications. Thirty type collections were studied, and ITS and LSU sequences are provided for 12 of these. A neotype is designated for O.
