The rust Cionothrix praelonga was reported in Trinidad for the first time, DOI 10.1080/09670879309371829 where it was found at two sites in Temple Village, Armina and on the Macqueripe Road, Chaguaramas. No seasonal fluctuation in the incidence of the disease was observed in the Language of Text field during the 2­year study. The optimum conditions for infection were established and English infection was achieved with laboratory­inoculated plants. Young leaves appeared to be more susceptible to infection than older tissues. The following three plant pathogenic fungi were Language of Summary identified as potential biological control agents: Septoria ekmaniana, Anhellia niger, and English Mycovellosiella perfoliata. Host specificity screening trials using 16 local composite weeds Geographical Location [family Asteraceae] known to be closely related to C. odorata indicated that C. praelonga was Trinidad and Tobago strictly host­specific while S. ekmaniana showed a very restricted host range.

Gareth Jones, [email protected] Abstract: Phylogenetic analyses of four nuclear genes, namely the large and small subunits of the nuclear ribosomal RNA, transcription elongation factor 1-alpha and the second largest RNA polymerase II subunit, established that the ecological group of marine bitunicate ascomycetes has representatives in the orders Capnodiales, Hysteriales, Jahnulales, Mytilinidiales, Patellariales and Pleosporales. Most of the fungi sequenced were intertidal mangrove taxa and belong to members of 12 families in the Pleosporales: Aigialaceae, Didymellaceae, Leptosphaeriaceae, Lenthitheciaceae, Lophiostomataceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae, Pleosporaceae, Testudinaceae and Trematosphaeriaceae. Two new families are described: Aigialaceae and Morosphaeriaceae, and three new genera proposed: Halomassarina, Morosphaeria and Rimora.

The family Elsinoaceae (type: Elsinoe canavaliae) is described and its separation from Myriangiaceae is supported. Butleria inaghatahani has characters similar to Elsinoaceae where it should remain. Beelia suttoniae appears to be a superficial biotroph on the surface of leaves and thus Beelia should be placed in Chaetothyriaceae and is most similar to Ainsworthia (= Phaeosaccardinula). Apart from the oblong to ovoid sessile asci in Hyalotheles dimerosperma, its placement in Elsinoaceae seems unwarranted, and Hyalotheles should be placed in Dothideomycetes incertae sedis. Saccardinula guaranitica may be better placed in Microthyriaceae or Brefeldiellaceae, because its ascomata greatly resemble thyrothecia found in Microthyriaceae and have similarities with Brefeldiella. Molecular sequence data from fresh collections is required to solve the problem of familial placement.

    JOTOAl OF AGRKETDRAl RESEARCH VOL. 42 WASHINGTON, D. C, JANUARY 1, 1931 No. 1 SCAB OF CANAVALIA CAUSED BYELSINOE CANAVALIAE' By ANNA E. JENKINS Associate Pathologist, Office of Mycology and Disease Survey, Bureau of Plant Industry, United States Department of Agriculture INTRODUCTION In connection with investigations of diseases caused by members of the form genus Sphaceloma De Bary (^Y and the ascomycetous genus Plectodiscella Woronichin (44, p. 2S2), the writer has had occasion to make a study of a Uttle-known disease of Canavaha (CanavaUa DC), including the morphology and the status of the classification of its causal fungus. This study has involved an exami- nation of certain other myriangioid fungi than those referred to above. As supplementing those already available, most of which are nientioned or cited in this account, the data thus obtained are here given for reference in connection with these investigations but pri- marily because of their direct bearing on the Canavalia disease and on a destructive disease of Lima bean (Phaseolus lunatus macro- carpus Benth.) now being investigated (19), The work is based upon material contained in the Mycological Collections of the Bureau of Plant Industry and in the United States National Herbarium. SPECIES OF CANAVALIA AFFECTED The disease of Canavalia here discussed has been reported as affect- ing two species of this genus, C. gladiata (Jacq.) DC. of Asiatic origin (28) and C. ensiformis (L.) DC. which '4t is practically certain * * * ig native to America.'' According to Piper (28) the former species is commonly known as sword or saber bean and the latter as jack or horse bean, and the two have been greatly confused.

  • An Investigation Into the Sarracenia Alata
    Do ecological communities co-diversify? An investigation into the Sarracenia alata pitcher plant system DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the Graduate School of The Ohio State University By Jordan David Satler Graduate Program in Evolution, Ecology, and Organismal Biology The Ohio State University 2016 Dissertation Committee: Dr. Bryan Carstens, Advisor Dr. Laura Kubatko Dr. John Freudenstein Copyright by Jordan David Satler 2016 Abstract Interactions among species are driving forces behind the formation, structure, and persistence of ecological communities. The nature of species interactions that characterize communities, however, has long been debated by ecologists, varying from communities as fluid entities to communities as evolving units. For species with obligate interactions (e.g., host and parasite, plant and pollinator), we might expect these ecologically dependent associations to be reflected in a shared evolutionary history, yet relatively few studies have demonstrated this process in nature. To address this central tenet in ecology and evolutionary biology, my research explores co-diversification in the Sarracenia alata pitcher plant system. Sarracenia alata (family Sarraceniaceae) is a carnivorous pitcher plant distributed along the Gulf Coast of the American southeast, bisected by the Mississippi River. Leaves of this plant are tube-shaped and filled with fluid, adapted for the capture and digestion of prey items. The breakdown of prey provides inorganic compounds to the plant, necessary in the nutrient-poor habitats where these plants are found. In addition to prey capture, the plant’s modified leaves harbor a unique biota of associated organisms (i.e., inquilines)—diverse species that share ecological relationships and often provide important services (e.g., secrete digestive enzymes) for the plant.

The family has not undergone any recent revision, however, molecular data has shown it to be a well-resolved family closely linked to Elsinoaceae in Myriangiales. Both morphological and molecular characters indicate that Elsinoaceae differs from Myriangiaceae. In Elsinoaceae, small numbers of asci form in locules in light coloured pseudostromata, which form typical scab-like blemishes on leaf or fruit surfaces.

    Subdivision: Ascomycotina, class: Hemiascomycetes (Taphrinales), class: Plectomycetes (Eurotiales), class: Pyrenomycetes (Erysiphales, Clavicepitales), class: Loculoascomycetes (Pleosporales) General characters Mycelium is well developed branched and septate. Yeast is single celled organism. Septum has a central pore. Cell wall is made up of chitin. Asexual spores are non-motile conidia. Sexual spores are ascospores. Ascospores are usually 8 in an ascus. They are produced endogenously inside the ascus. Key to the classes of Ascomycotina Ascocarps and ascogenous hyphae absent, thallus mycelial or yeast-like - Hemiascomycetes Ascocarps and ascogenous hyphae present, Thallus mycelial: Asci bitunicate, ascocarp an ascostroma - Loculoascomycetes Asci typically unitunicate, if bitunicate, ascocarp as apothecium: Ascocarp a cleistothecium, asci evanescent and scattered - Plectomycetes Asci regularly arranged as basal or peripheral layer in the ascocarp Insect parasites - Laboulbeniomycetes Not insect parasites, Ascocarp perithecium - Pyrenomycetes Ascocarp apothecium – Discomycetes Class: Hemiascomycetes The class is characterized by the lack of ascocarp, vegetative phase comprising of unicellular thallus or poorly developed mycelium. It is divided into three orders: 1. Asci developing parthenogenetically from a single cell or directly from a zygote formed by population of 2 cells - Endomycetales 2.
