“…Identification of Colletotrichum species has been difficult due to the lack of reliable morphological features and confused, ambiguous species boundaries (Hyde et al 2009a, b;Cai et al 2009). Difficulties in recognising Colletotrichum species has resulted from having a few and variable morphological characters, widespread host ranges and pathogenicity, lost specimens or type specimens in poor condition and incorrectly named sequences in NCBI (Freeman et al 2000;Du et al 2005;Thaung 2008;Crouch et al 2009a, b;Damm et al 2009;Cai et al 2009). …”

Many fungi are pathogenic on plants and cause significant damage in agriculture and forestry. They are also part of the natural ecosystem and may play a role in regulating plant numbers/density. Morphological identification and analysis of plant pathogenic fungi, while important, is often hampered by the scarcity of discriminatory taxonomic characters and the endophytic or inconspicuous nature of these fungi. Molecular (DNA sequence) data for plant pathogenic fungi have emerged as key information for diagnostic and classification studies, although hampered in part by non-standard laboratory practices and analytical methods. To facilitate current and future research, this study provides phylogenetic synopses for 25 groups of plant pathogenic fungi in the Ascomycota, Basidiomycota, Mucormycotina (Fungi), and Oomycota, using recent molecular data, up-to-date names, and the latest taxonomic insights. Lineagespecific laboratory protocols together with advice on their application, as well as general observations, are also provided. We hope to maintain updated backbone trees of these fungal lineages over time and to publish them jointly as new data emerge. Researchers of plant pathogenic fungi not covered by the present study are invited to join this future effort. Bipolaris, Botryosphaeriaceae,

“…The early taxonomic system for Colletotrichum based on morphology and host–plant association was deficient and to a great extent hindered research on species diversity [ 26 , 27 , 28 , 29 , 30 ]. It is of great significance to improve the accuracy of plant pathogen identification for effective control of plant diseases [ 26 , 31 ].…”

Viburnum odoratissimum Ker-Gawl is native to Asia and is usually used as a garden ornamental. In September 2022, a leaf blotch on V. odoratissimum was observed in Nanjing, Jiangsu, China. The disease causes the leaves of the plants to curl and dry up and defoliate early. It not only seriously affects the growth of the plants but also greatly reduces the ornamental value. The pathogenic fungus was isolated from the diseased leaves, and the fungus was identified to be Colletotrichum siamense based on morphological features and multilocus phylogenetic analyses of the internal transcribed spacer (ITS) region, actin (ACT), calmodulin (CAL), beta-tubulin 2 (TUB2), chitin synthase (CHS-1), Apn2-Mat1-2 intergenic spacer and partial mating type (ApMat), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) genes. Pathogenicity tests were performed by inoculating healthy leaves with conidia. C. siamense can grow at 15–35 °C, with an optimal growth temperature at 25–30 °C. The results of sensitivity to nine fungicides showed that C. siamense was the most sensitive to prochloraz in the concentration range of 0.01 μg/mL to 100 μg/mL. Therefore, spraying prochloraz before the optimum growth temperature of pathogenic fungus can achieve effective control. It provided useful information for future studies on the prevention and treatment strategies of C. siamense. This is the first report of leaf blotch caused by C. siamense on V. odoratissimum in China and worldwide.

“…Furthermore, Pestalotiopsis species exhibit a wide variety of relationships with their hosts. They have been reported to be saprobes, endophytes and facultative pathogens (Hu et al 2007;Metz et al 2000), are ubiquitous in distribution and are found on a wide range of substrates (Jeewon et al 2003;Thaung 2008). Also, they are not host-specific (Hu et al 2007) and can thrive over a wide range of temperatures, pH and matric potentials (Hopkins and McQuilken 2000;McQuilken and Hopkins 2004), indicating that they are adapted to a range of environmental conditions.…”

A trial involving the mass propagation of Argania spinosa cuttings was established following two protocols: in mini-bouturathèques without mist and in a greenhouse under mist. Symptoms of petiole necrosis, foliar yellowing and abundant black acervuli were observed under both protocols. These symptoms were responsible for a 90% mortality rate in the mini-bouturathèques while under the mist treatment premature fatal necrosis of the apical buds resulted in 100% mortality. The disease’s causal agent, Pestalotiopsis clavispora, was identified on the basis of its morphological characteristics and by molecular analysis. Alternating weekly treatments of systemic and contact fungicides resulted in a 41% success rate in controlling this pathogen, described for the first time on argan cuttings.
