Fungi and Their Potential As Biological Control Agents of Beech Bark Disease
Fungi and their potential as biological control agents of Beech Bark Disease By Sarah Elizabeth Thomas A thesis submitted for the degree of Doctor of Philosophy School of Biological Sciences Royal Holloway, University of London 2014 1 DECLARATION OF AUTHORSHIP I, Sarah Elizabeth Thomas, hereby declare that this thesis and the work presented in it is entirely my own. Where I have consulted the work of others, this is always clearly stated. Signed: _____________ Date: 4th May 2014 2 ABSTRACT Beech bark disease (BBD) is an invasive insect and pathogen disease complex that is currently devastating American beech (Fagus grandifolia) in North America. The disease complex consists of the sap-sucking scale insect, Cryptococcus fagisuga and sequential attack by Neonectria fungi (principally Neonectria faginata). The scale insect is not native to North America and is thought to have been introduced there on seedlings of F. sylvatica from Europe. Conventional control strategies are of limited efficacy in forestry systems and removal of heavily infested trees is the only successful method to reduce the spread of the disease. However, an alternative strategy could be the use of biological control, using fungi. Fungal endophytes and/or entomopathogenic fungi (EPF) could have potential for both the insect and fungal components of this highly invasive disease. Over 600 endophytes were isolated from healthy stems of F. sylvatica and 13 EPF were isolated from C. fagisuga cadavers in its centre of origin. A selection of these isolates was screened in vitro for their suitability as biological control agents. Two Beauveria and two Lecanicillium isolates were assessed for their suitability as biological control agents for C. -

Many studies 22 have examined these endophytes within a single plant species and/or at small spatial scales, but landscape-scale 23 variables that determine their community composition are not well understood, either across geographic space, 24 across climatic conditions, or in the context of host plant phylogeny. Here, we evaluate the contributions of these 25 variables to endophyte beta diversity using a survey of foliar endophytic fungi in native Hawaiian dicots 26 sampled across the Hawaiian archipelago. -

Two fresh specimens associated with canker and dieback of Betula platyphylla were made in Beijing, China in 2015. Morphological and multi-gene, combined, phylogenetic analyses (ITS, tef1-α and β-tub) support these speciemens as a distinct and new species of Cryptosporella, from a unique host, Betula platyphylla. Cryptosporella platyphylla sp. nov. is introduced with an illustrated account and differs from similar species in its host as- sociation and multigene phylogeny. Key words: Diaporthales, Disculina, Gnomoniaceae, systematics, taxonomy Introduction Cryptosporella was introduced by Saccardo (1877) and was distinguished from Cryptospora based on the morphology of the ascospores. The genus subsequently entered a long period of confusion with the gnomoniaceous genera Ophiovalsa Petr. and Winterella (Sacc.) O. -

A Taxonomic and Phylogenetic Investigation of Conifer Endophytes
A Taxonomic and Phylogenetic Investigation of Conifer Endophytes of Eastern Canada by Joey B. Tanney A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biology Carleton University Ottawa, Ontario © 2016 Abstract Research interest in endophytic fungi has increased substantially, yet is the current research paradigm capable of addressing fundamental taxonomic questions? More than half of the ca. 30,000 endophyte sequences accessioned into GenBank are unidentified to the family rank and this disparity grows every year. The problems with identifying endophytes are a lack of taxonomically informative morphological characters in vitro and a paucity of relevant DNA reference sequences. A study involving ca. 2,600 Picea endophyte cultures from the Acadian Forest Region in Eastern Canada sought to address these taxonomic issues with a combined approach involving molecular methods, classical taxonomy, and field work. It was hypothesized that foliar endophytes have complex life histories involving saprotrophic reproductive stages associated with the host foliage, alternative host substrates, or alternate hosts. Based on inferences from phylogenetic data, new field collections or herbarium specimens were sought to connect unidentifiable endophytes with identifiable material. Approximately 40 endophytes were connected with identifiable material, which resulted in the description of four novel genera and 21 novel species and substantial progress in endophyte taxonomy. Endophytes were connected with saprotrophs and exhibited reproductive stages on non-foliar tissues or different hosts. These results provide support for the foraging ascomycete hypothesis, postulating that for some fungi endophytism is a secondary life history strategy that facilitates persistence and dispersal in the absence of a primary host. -
Anthracnose Common Foliage Disease of Deciduous Trees
Anthracnose Common foliage disease of deciduous trees Pathogen—Anthracnose diseases are caused by a group of morphologically similar fungi that produce cushion-shaped fruiting structures called acervuli (fig. 1). Many of the fungi that cause anthracnose diseases are known for their asexual stage (conidial), but most also have sexual stages. Taxonomy is con- tinually being updated, so scientific names can be confusing. A list of common anthracnose diseases in the Rocky Mountain Region and their hosts is provided in table 1. Hosts—A variety of deciduous trees are susceptible to anthracnose diseases, including ash, basswood, elm, maple, oak, sycamore, and walnut. These diseases are common on shade trees. Marssonina blight of aspen (see the Marssonina Leaf Blight entry in this guide for more information) is an anthracnose-type disease. The fungi that cause anthracnose diseases are host-specific such that one particular fungus can generally only parasitize one host genus. For example, Apiognomonia errabunda causes anthracnose only on species of ash, and A. quercina causes anthracnose only on oaks. Figure 1.
