“…Diaporthaceae was introduced by von Höhnel (1917) and subsequently involved in confusing the taxonomy due to many genera with wide variation of morphological characters and the majority without culture or DNA phylogeny. Senanayake et al (2017, 2018) accepted 14 genera in Diaporthaceae, including Allantoporthe , Apioporthella , Chaetoconis , Chiangraiomyces , Diaporthe , Hyaliappendispora , Leucodiaporthe , Mazzantia , Ophiodiaporthe , Paradiaporthe , Phaeocytostroma , Phaeodiaporthe , Pustulomyces , and Stenocarpella .…”

“…The family Erythrogloeaceae was recently introduced by Senanayake et al (2017) based on ITS, LSU, rpb2 and tef1-α , and included four genera ( Chrysocrypta , Dendrostoma , Disculoides and Erythrogloeum ) (Fan et al 2018a, Senanayake et al 2018).…”

“…The classification of Diaporthales has been confused over the past decades because of the wide variation in morphological characters. Several recent studies have helped to resolve taxonomic problems of Diaporthales by multigene phylogenetic analyses and accepted 30 families in the order (Senanayake et al 2017, 2018, Braun et al 2018, Fan et al 2018a, Crous et al 2019, Guterres et al 2019, Xavier et al 2019).…”

Diaporthales is a fungal order comprising important plant pathogens, saprobes and endophytes on a wide range of woody hosts. It is often difficult to differentiate the pathogens in this order, since both the morphology and disease symptoms are similar among the various species. In the current study, we obtained 15 representative diaporthalean isolates from six tree hosts belonging to plant families Betulaceae, Fagaceae, Juglandaceae, Rosaceae, and Ulmaceae from Mount Dongling in China. Six species were identified residing in four families of Diaporthales (Diaporthaceae, Erythrogloeaceae, Juglanconidaceae and Melanconidaceae). Based on morphological comparison and the phylogenetic analyses of partial ITS, LSU, cal, his3, rpb2, tef1-α and tub2 gene sequences, we identified five known species (Diaporthe betulina, D. eres, D. rostrata, Juglamconis oblonga and Melanconis stilbostoma) and one novel species (Dendrostoma donglinensis). These results represent the first study of diaporthalean fungi associated with canker and dieback symptoms from Mount Dongling in Beijing, China.

“…The quality of our amplified nucleotide sequences was checked and combined by SeqMan v.7.1.0 and reference sequences were retrieved from the National Center for Biotechnology Information ( NCBI ), based on Mejía et al (2011a) , Senanayake et al (2018) , Jiang and Tian (2019) , and Jiang et al (2019) , supplemented by sequences of Tenuignomonia styracis and Neognomoniopsis quercina from Crous et al (2019) and Minoshima et al (2019) . Sequences were aligned using MAFFT v. 6 ( Katoh and Toh 2010 ) and manually corrected using Bioedit 7.0.9.0 ( Hall 1999 ).…”

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.

“…In this sense, the genus Melanconis was one of many genera of the large family Melanconidaceae and was defined by a distinct ectostromatic disc, a more or less well-developed entostroma, twocelled hyaline or brown ascospores with or without appendages, in combination with melanconium-or discosporium-like asexual morphs (Barr 1978). The first phylogenetic analyses of the Diaporthales (Castlebury et al 2002; see also Jaklitsch et al 2016, Senanayake et al 2018, however, suggested that Melanconidaceae should be confined to its type genus Melanconis with a restricted number of species. This phylogenetic generic concept corresponds, apart from a few exceptions, with Wehmeyer's (1941) section Stilbostomae of his subgenus Eumelanconis.…”

The genus Melanconis (Melanconidaceae, Diaporthales) in the strict sense is here re-evaluated regarding phylogenetic structure, taxonomy, distribution and ecology. Using a matrix of sequences from ITS, LSU, ms204, rpb2, tef1 and tub2, eight species are recognised and their phylogenetic positions are determined. Based on phylogenetic, morphological and geographical differentiation, Melanconis marginalis is subdivided into four subspecies. Melanconis italica is reduced to a subspecies of Melanconis marginalis. The two species Melanconis larissae from Betula sp. and M. pacifica from Alnus rubra are described as new. Melanconis alni and M. stilbostoma are lectotypified and M. alni, M. marginalis and M. stilbostoma are epitypified. All GenBank sequences deposited as Melanconis alni are shown to actually represent M. marginalis and those as M. marginalis belong to the newly described M. pacifica. Currently, Alnus and Betula are the sole host genera of Melanconis. All species and subspecies are (re-)described and illustrated. In addition, the neotypification of Melanconium pterocaryae is here validated.
