COLLETOTRICHUM INTRODUCTION Colletotrichum (sexual stage: Glomerella) is a genus of fungi that are symbionts to plants as endophytes (living within the plant) or phytopathogens. Many of the species in this genus are plant pathogens, but some species may have a mutualistic relationship with hosts. Higher classification: Glomerellaceae Scientific name: Colletotrichum Order: Glomerellales Class: Sordariomycetes Kingdom: Fungi COMMON DISEASES Diseases caused by the fungus Colletotrichum, particularly leaf spots, are very common in plant production nurseries. This pathogen attacks a very wide range of ornamental, fruit and vegetable species, causing the disease commonly known as “anthracnose”. SYMPTOMS Symptoms include sunken spots or lesions (blight) of various colours in leaves, stems, fruits, or flowers, and some infections form cankers on twigs and branches. The severity of the infection depends on both the causative agent and the infected species and can range from mere unsightliness to death. SOME PATHOGENIC SPECIES Colletotrichum capsici Colletotrichum capsici is a species of fungus and plant pathogen which causes leaf blight on Chlorophytum borivilianum, basil, chickpea and pepper as well as dieback in pigeonpea and anthracnose in poinsettia. Colletotrichum lindemuthianum Colletotrichum lindemuthianum is a fungus which causes anthracnose, or black spot disease, of the common bean plant (Phaseolus vulgaris). It is considered a hemibiotrophic pathogen because it spends part of its infection cycle as a biotroph, living off of the host but not harming it, and the other part as a necrotroph, killing and obtaining nutrients from the host tissues. Glomerella cingulata Glomerella cingulata is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage (anamorph) is called Colletotrichum gloeosporioides. For most of this article the pathogen will be referred to as C. gloeosporioides .

Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph generaDischloridium with Monilochaetes.

Bhoye 1Department of Plant Pathology, Dr. Panjabrao Deashmukh Krishi Vidyapeeth, Akola, India 2Mahatma Phule Agricultural University, Rahuri, Dist Ahmednagar, India ABSTRACT Background: Pigeon pea (Cajanus cajan) is one of the important leguminous crop of the tropics and subtropics and is infected by the wilt pathogen Neocosmospora vasinfecta in addition to Fusarium udum. Objective: Hence, the study was undertaken to see the in vitro effect of different fungicides (Thiram 75 WP, Carbendazim 50 WP, Chlorothalonil 75 WP, Metalaxyl MZ 72 WP, Thiram+Cabendazim (2:1), Carbendazim+mancozeb 75 WP, Tricyclazole+Mancozeb 80 WP, Zineb+Hexaconazole 72 WP) and bioagents (Trichoderma harzianum, Pseudomonas fluorescens, Bacillus subtilis) against the pathogen. Methodology: The efficacy of fungicides was assayed by poisoned food technique and of bioagents was assayed by dual culture technique. Results: It was found that among eight fungicides tested carbendazim (0.1%), combination of carbendazim+mancozeb (0.2 %) and thiram+carbendazim 2:1 (0.3%) exhibited cent per cent inhibition of N. vasinfecta, other fungicides were also significant over control. Whereas among bioagents tested, Trichoderma herzianum (50.30%) showed maximum per cent growth inhibition of the pathogen followed by Bacillus subtilis (41.47%). Conclusion: Thus it was proved that the fungicides viz. carbendazim, combinations of carbendazim+mancozeb and thiram+carbendazim as well as bioagent, T. herzianum were effective against Neocosmospora wilt of pigeon pea under in vitro condition.

Crous1,2,3 Received: 8 April 2019 /Revised: 17 July 2019 /Accepted: 2 August 2019 # The Author(s) 2019 Abstract During 2017, the Westerdijk Fungal Biodiversity Institute (WI) and the Utrecht University Museum launched a Citizen Science project. Dutch school children collected soil samples from gardens at different localities in the Netherlands, and submitted them to the WI where they were analysed in order to find new fungal species. Around 3000 fungal isolates, including filamentous fungi and yeasts, were cultured, preserved and submitted for DNA sequencing. Through analysis of the ITS and LSU sequences from the obtained isolates, several plectosphaerellaceous fungi were identified for further study. Based on morphological characters and the combined analysis of the ITS and TEF1-α sequences, some isolates were found to represent new species in the genera Phialoparvum,i.e.Ph. maaspleinense and Ph. rietveltiae,andPlectosphaerella,i.e.Pl. hanneae and Pl. verschoorii, which are described and illustrated here.

Single gene phylogenetic analyses have also not proved to be very successful in delineating species. This may be partly due to the high level of erroneous names in GenBank. In this paper we review the problems associated with taxonomy of Colletotrichum and difficulties in identifying taxa to species. We advocate epitypification and use of multi-locus phylogeny to delimit species and gain a better understanding of the genus. We review the lifestyles of Colletotrichum species, which may occur as epiphytes, endophytes, saprobes and pathogens.

Colletotrichum Acutatum
Prepared by CABI and EPPO for the EU under Contract 90/399003 Data Sheets on Quarantine Pests Colletotrichum acutatum IDENTITY Name: Colletotrichum acutatum Simmonds Synonyms: Colletotrichum xanthii Halsted Taxonomic position: Fungi: Ascomycetes: Polystigmatales (probable anamorph) Common names: Anthracnose, black spot (of strawberry), terminal crook disease (of pine), leaf curl (of anemone and celery), crown rot (especially of anemone and celery) (English) Taches noires du fraisier (French) Manchas negras del fresón (Spanish) Notes on taxonomy and nomenclature: The classification of the genus Colletotrichum is currently very unsatisfactory, and several species occur on the principal economic host (strawberry) which are regularly confused. As well as C. acutatum, these include the Glomerella cingulata anamorphs C. fragariae and C. gloeosporioides, all of which can be distinguished by isozyme analysis (Bonde et al., 1991). Studies are continuing. Colletotrichum xanthii appears to be an earlier name for C. acutatum, but more research is necessary before it is adopted in plant pathology circles. Bayer computer code: COLLAC EU Annex designation: II/A2 HOSTS The species has a very wide host range, but is economically most important on strawberries (Fragaria ananassa). Other cultivated hosts include Anemone coronaria, apples (Malus pumila), aubergines (Solanum melongena), avocados (Persea americana), Camellia spp., Capsicum annuum, Ceanothus spp., celery (Apium graveolens), coffee (Coffea arabica), guavas (Psidium guajava), olives (Olea europea), pawpaws (Carica papaya), Pinus (especially P. radiata and P. elliottii), tamarillos (Cyphomandra betacea), tomatoes (Lycopersicon esculentum), Tsuga heterophylla and Zinnia spp. Colletotrichum acutatum can apparently affect almost any flowering plant, especially in warm temperate or tropical regions, although its host range needs further clarification.

The inspector submitted leaves showing dieback symptoms to CDFA’s Plant pest diagnostics center for diagnosis. From the leaf spots, CDFA plant pathologist Timothy Tidwell identified the fungal pathogen Colletotrichum capsici, which was not known to be present in California, and assigned a temporary Q rating. In 2015, a sample was submitted by Los Angeles County agricultural inspectors from Ficus plants shipping from Florida. Plant Pathologist Suzanne Latham diagnosed C. truncatum, a species that was synonymized with C. capsisi in 2009, from the leaf spots. She was able to culture the fungus from leaf spots and confirm its identity by PCR and DNA sequencing. Between 2016 and 2020, multiple samples of alfalfa plants from Imperial County with leafspots and dieback were submitted to the CDFA labs as part of the PQ seed quarantine program with infections from C. truncatum. Seed mother plants must be free-from specific disease of quarantine significance in order to be given phytosanitary certificates for export. Although not a pest of concern for alfalfa, C. truncatum is on the list for beans grown for export seed. The risk to California from C.

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.

Damm, [email protected], Present address: Senckenberg Museum of Natural History Görlitz, PF 300 154, 02806 Görlitz, Germany. Abstract: Colletotrichum destructivum is an important plant pathogen, mainly of forage and grain legumes including clover, alfalfa, cowpea and lentil, but has also been reported as an anthracnose pathogen of many other plants worldwide. Several Colletotrichum isolates, previously reported as closely related to C. destructivum, are known to establish hemibiotrophic infections in different hosts. The inconsistent application of names to those isolates based on outdated species concepts has caused much taxonomic confusion, particularly in the plant pathology literature. A multilocus DNA sequence analysis (ITS, GAPDH, CHS-1, HIS3, ACT, TUB2) of 83 isolates of C. destructivum and related species revealed 16 clades that are recognised as separate species in the C. destructivum complex, which includes C. destructivum, C. fuscum, C. higginsianum, C. lini and C. tabacum. Each of these species is lecto-, epi- or neotypified in this study. Additionally, eight species, namely C. americae- borealis, C. antirrhinicola, C. bryoniicola, C.
