ASHRAF, N., BHAT, M. Y., WANI, A. H., 2020: First record of Diplocarpon mespili (Drepanopezizaceae, Ascomycota) on Cydonia oblongata leaves from Kashmir Valley, India. – Österr. Z. Pilzk. 28: 45–48. Key words: Entomosporium mespili, leaf spot, foliicolous, quince, pathogenicity, pathogen. – Mycota of India. Zusammenfassung: Blätter der Quitte (Cydonia oblongata) werden von einer Reihe von Pilzpathoge- nen befallen. Diese Pathogene führen zu Blattflecken verschiedener Art, die wiederum die Photosyn- these und damit den Ernteertrag verringern. Die vorliegende Studie wurde durchgeführt, um Pilze zu identifizieren, die mit starken Blattflecken von Quitten assoziiert sind. Es zeigte sich, dass die asexuelle Morphe von Diplocarpon mespili, eines foliicolen Ascomyceten, für rötliche Flecken an Quittenblättern verantwortlich war. Dieser Pilz ist durch typische insektenförmige Konidien gekennzeichnet. Er wurde auf PDA kultiviert und 30 Tage bei 24 ± 2 °C inkubiert. Pathogenitätstests an gesunden Blättern in vitro ergaben das Auftreten typischer Blattflecken. Dies ist der erste Bericht von Diplocarpon mespili als Auslöser für Blattflecken der Quitte aus dem indischen Kashmir-Tal. Abstract: Quince (Cydonia oblongata) leaves are attacked by a number of fungal pathogens. These pathogens result in leaf spots of various types which in turn reduce photosynthesis, hence decrease the crop yield. The present study was conducted to identify a fungus associated with severe leaf spot of quince. It was revealed, that the asexual state of Diplocarpon mespili, a foliicolous ascomycete, was responsible for reddish spots of quince leaves. The fungus is characterised by typical insect-shaped co- nidia. It was cultured on PDA and incubated at 24 ± 2 °C for 30 days. Pathogenicity tests conducted on healthy leaves in vitro resulted in appearance of typical leaf spots. This is the first report of Diplocarpon mespili responsible for leaf spot of quince from Kashmir Valley, India. .

1 Original Research Article 2 3 THE MALOIDEAE (ROSACEAE) STRUCTURAL AND FUNCTIONAL FEATURES 4 DETERMINING PASSIVE IMMUNITY TO MYCOSIS 5 6 7 With the help of microscopic methods the leaves and fruits surface tissues of plants of four 8 genera of the Maloideae subfamily were screened: Malus Mill., Pyrus L., Cydonia Mill., 9 Mespilus L., as model objects, and attempts were made to explain the dependence of mycosis 10 damage on microstructural features. The species composition of fungi that cause damage to the 11 Maloideae leaves and fruits in the Russia southern regions is analyzed. It is established that 12 among pathogens with different types of parasitism there are common excitants, as well as 13 highly specialized, more represented on Mespilus germanica. Higher resistance to the complex 14 of fungal diseases, in comparison with apple and pear, was found in quince and medlar. This 15 stability at the initial stage of the pathological process is associated with structural features such 16 as micromorphology of the fruits and stomata cuticle in the abaxial leaves epidermis. The leaves 17 stomatal cracks of the medlar are narrow with raised outgrowths, on the surface of the fruit – the 18 layered structure of the cuticular layer. Quince has a powerful continuous cuticular cover. 19 Compared with Malus and Pyrus, Cydonia and Mespilus also have a large (30 % or more) 20 polyphenol content in the pericarp outer layer cells. In addition to the gender-specific differences 21 in the microstructure of the integumentary tissues and the content of polyphenols affecting the 22 resistance to pathogens at the stage of their penetration, general patterns of leaf surface 23 formation, such as hypostomacy, anomocytic stomata, folded microrelief of the cuticular surface, 24 and the presence of single and multicellular trichomes are noted.

Crataegus (Hawthorn)
nysipm.cornell.edu 2019 Search for this title at the NYSIPM Publications collection: ecommons.cornell.edu/handle/1813/41246 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University CRATAEGUS Hawthorn pixabay.com Crataegus is a large genus of shrubs and small trees in the rose family commonly known as hawthorn. This popular ornamental has showy pink or white flowers in spring and colorful berry-like fruit. Some species also have long thorns that provide protection for wildlife but may be a hazard in the landscape–thornless cultivars are available. Like other rosaceous plants, hawthorns are sus- ceptible to a number of diseases including fire blight, scab, leaf spot and several types of rust. Insect pests include lace bugs and leaf miners. DISEASES Cedar Rust diseases on hawthorn, which include hawthorn rust and quince rust, are caused by sev- eral fungi in the genus Gymnosporangium that spend part of their life cycle on Eastern red cedar (Juni- perus virginiana) and other susceptible junipers, and another part of their life cycle on plants in the rose family, especially Malus and Crataegus. Since two hosts are required for these fungi to complete their life cycle, one way to reduce disease problems is to avoid planting alternate hosts near each other. Hawthorn Rust, caused by Gymnosporangium globosum, is a significant concern for Crataegus spp. in the Northeast (7). Hawthorns are the main broadleaved host for this rust, and yellow-orange leaf spots are the most common symptom. (8). With severe infections, foliage may turn bright yellow and drop prematurely (15).

Characterising plant pathogen communities and their environmental drivers at a national scale A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University by Andreas Makiola Lincoln University, New Zealand 2019 General abstract Plant pathogens play a critical role for global food security, conservation of natural ecosystems and future resilience and sustainability of ecosystem services in general. Thus, it is crucial to understand the large-scale processes that shape plant pathogen communities. The recent drop in DNA sequencing costs offers, for the first time, the opportunity to study multiple plant pathogens simultaneously in their naturally occurring environment effectively at large scale. In this thesis, my aims were (1) to employ next-generation sequencing (NGS) based metabarcoding for the detection and identification of plant pathogens at the ecosystem scale in New Zealand, (2) to characterise plant pathogen communities, and (3) to determine the environmental drivers of these communities. First, I investigated the suitability of NGS for the detection, identification and quantification of plant pathogens using rust fungi as a model system.

An Inventory of Fungal Diversity in Ohio Research Thesis Presented In
An Inventory of Fungal Diversity in Ohio Research Thesis Presented in partial fulfillment of the requirements for graduation with research distinction in the undergraduate colleges of The Ohio State University by Django Grootmyers The Ohio State University April 2021 1 ABSTRACT Fungi are a large and diverse group of eukaryotic organisms that play important roles in nutrient cycling in ecosystems worldwide. Fungi are poorly documented compared to plants in Ohio despite 197 years of collecting activity, and an attempt to compile all the species of fungi known from Ohio has not been completed since 1894. This paper compiles the species of fungi currently known from Ohio based on vouchered fungal collections available in digitized form at the Mycology Collections Portal (MyCoPortal) and other online collections databases and new collections by the author. All groups of fungi are treated, including lichens and microfungi. 69,795 total records of Ohio fungi were processed, resulting in a list of 4,865 total species-level taxa. 250 of these taxa are newly reported from Ohio in this work. 229 of the taxa known from Ohio are species that were originally described from Ohio. A number of potentially novel fungal species were discovered over the course of this study and will be described in future publications. The insights gained from this work will be useful in facilitating future research on Ohio fungi, developing more comprehensive and modern guides to Ohio fungi, and beginning to investigate the possibility of fungal conservation in Ohio. INTRODUCTION Fungi are a large and very diverse group of organisms that play a variety of vital roles in natural and agricultural ecosystems: as decomposers (Lindahl, Taylor and Finlay 2002), mycorrhizal partners of plant species (Van Der Heijden et al.
