“…Flavignomonia rhoigena is the type species of Flavignomonia in the family Gnomoniaceae. It can be easily distinguished from the other gnomoniaceous genera by its unique conidiomata (Walker et al 2004, Senanayake et al 2018, Crous et al 2019, Minoshima et al 2019).…”

“…The BLAST results showed that three isolates were grouped in the family Gnomoniaceae, and five isolates in the genus Synnemasporella . The phylogenetic analyses for the three gnomoniaceous isolates were conducted based on Senanayake et al (2018), supplemented by sequences of Tenuignomonia styracis and Neognomoniopsis quercina from Crous et al (2019) and Minoshima et al (2019). Melanconis marginalis (CBS 109744) in Melanconidaceae was selected as the out-group taxon.…”

“…In the recent monograph of Diaporthales, 34 genera were accepted in the family Gnomoniaceae (Senanayake et al 2018). Subsequently, Neognomoniopsis and Tenuignomonia were added based on both molecular and morphological evidence (Crous et al 2019, Minoshima et al 2019).…”

Rhus chinensis represents a commercially and ecologically important tree species in China, but suffers from canker diseases in Jiangxi Province. Synnemata, pycnidia and ascomata were discovered on cankered tissues. Strains were obtained from single ascospore or conidium within the fruiting bodies and identified based on morphological comparison and the phylogenetic analyses of partial ITS, LSU, tef1 and rpb2 gene sequences. As a result, two species were confirmed to represent two kinds of synnemata. One of these species is described herein as Flavignomonia rhoigenagen. et sp. nov.; and Synnemasporella aculeans is illustrated showing ascomata, pycnidia and synnemata. Flavignomonia is distinguished from Synnemasporella by the colour of the synnematal tips. Additionally, Flavignomonia can be distinguished from the other gnomoniaceous genera by the formation of synnemata.

“…Based on phylogenetic analyses and morphological characteristics, Senanayake et al (2017) described new taxa and excluded some genera from Gnomoniaceae. Since then, additional genera have been introduced for species observed in sexual developmental stages, as well as those that have only been observed as pycnidial asexual morphs, and rarely for species known in both sexual and asexual forms (Senanayake et al 2018;Crous et al 2019;Minoshima et al 2019;Yang et al 2020).…”

A new study of Nagrajomyces: with two new species proposed and taxonomic status inferred by phylogenetic methods

Nagrajomyces (incertae sedis, Ascomycota) is a monotypic genus with a previously unknown systematic position. In this report, two new species are proposed, Nagrajomyces fusiformis and Nagrajomyces laojunshanensis. These new taxa are proposed based on morphological characteristics evident via light microscopy and molecular data. Multi-locus phylogenetic analyses (ITS rDNA, nrLSU rDNA, RPB2, and TEF1-α) show that specimens recently collected in Yunnan Province, China are closely related to Gnomoniaceae. Both new species and known species were discovered repeatedly in their asexual developmental form exclusively on twigs of Rhododendron spp. (Ericaceae). This indicates a host specificity of Nagrajomyces spp. for species of Rhododendron.

Species of Gnomoniaceae are commonly associated with leaf spot diseases of a wide range of plant hosts worldwide. During our investigation of fungi associated with tree diseases in China, several gnomoniaceous isolates were recovered from symptomatic branches and leaves on different woody plants in the Fagaceae, Pinaceae, and Salicaceae families. These isolates were studied by applying a polyphasic approach including morphological, cultural data, and phylogenetic analyses of partial ITS, LSU, tef1, rpb2 and tub2 gene sequences. As a result, three species were identified with characters fitting into the family Gnomoniaceae. One of these species is described herein as Cryphognomonia pinigen. et sp. nov., characterized by developed pseudostromata and ascospores with obvious hyaline sheath; Gnomoniopsis xunwuensissp. nov. is illustrated showing sympodially branched conidiophore, oval or fusiform conidia; and one known species, Plagiostoma populinum. The current study improves the understanding of gnomoniaceous species causing diebacks and leaf spot on ecological and economic forest trees.
