... However, El. semicircularis differs in its mature urn-shaped ascus and smaller reddish-brown ascospores (4.5-7(−11) × 1.5-2(−2.5) μm; Chacón et al. 2013); Eutypa crustata differs from El. motuoensis by having smaller perithecia (300-450 μm) and smaller ascus (20-35 × 6-8 μm; Rappaz, 1987); Echinomyces obesa is separated from El. motuoensis by smaller ascus (10-15 × 4-5 μm) and ascospores (3.5-7.5 × 1.2-1.5 μm; Rappaz, 1987); Diatrype falcata differs in its less prominent ostioles, smaller perithecia (250-350 μm), smaller ascus (20-25 × 4-5 μm), and ascospores (5.8-7.5 × 1.2-1.5 μm; Rappaz, 1987). In the phylogenetic tree, El. motuoensis is sister to El. persica Mehrabi, Asgari & Hemmati, though their relationship is not strongly supported. ...
In this study, we investigated the diversity of diatrypaceous fungi from southeastern Tibet in China. The phylogenetic analyses were carried out based on ITS and β-tubulin sequences of 75 taxa of Diatrypaceae from around the world. Based on a combination of morphological features and molecular evidence, a new genus-Alloeutypa, with three new species-A. milinensis, Diatrype linzhiensis, and Eutypella motuoensis, and a new combination-A. flavovirens, were revealed by the materials in China. Alloeutypa is characterized by stromatal interior olivaceous buff, stromata producing well-developed discrete, and ascospores allantoid, subhyaline. These characteristics separate the new genus from the similar genus Eutypa. Comprehensive morphological descriptions, illustrations, and a phylogenetic tree to show the placement of new taxa are provided. All novelties described herein are morphologically illustrated and phylogeny investigated to better integrate taxa into the higher taxonomic framework and infer their phylogenetic relationships as well as establish new genera and species. Our results indicate that the diatrypaceous fungi harbor higher species diversity in China.
... In the past, this family belonged to Diatrypales and in current classification Diatrypaceae belongs to Xylariales (Augusto et al. 2016;Hyde et al. 2020d;Wijayawardene et al. 2020). Diatrypaceous taxa are most likely colonise any kind of ecosystem with woody plants in both aquatic and terrestrial habitats and some are pathogens of economic crops as well as forest trees (Chacón et al. 2013;Senanayake et al. 2015;Dayarathne et al. 2016;Hyde et al. 2020d;Konta et al. 2020). There are 20 genera accounted to Diatrypaceae (Wijayawardene et al. 2020). ...

... Although 251 species epithets of Eutypella have been listed in Index Fungorum (2021), the most of species are lacking DNA sequence. In phylogenetic analyses of Diatrypaceae, it showed that Eutypella was polyphyletic (Acero et al., 2004;Chacón et al., 2013;de Almeida et al., 2016;Shang et al., 2017). Thus, further studies of the taxa in Eutypella is needed. ...
... The number of ascospores per ascus (eight spores vs. multiple spores) has been used traditionally to differentiate the genera of Diatrypaceae (Diatrype vs. Diatrypella and Cryptovalsa vs. Eutypella). However, the recent studies indicated that the polysporous ascus feature maybe not significant in Diatrypaceae (Acero et al., 2004;Trouillas et al., 2011;Chacón et al., 2013;Liu et al., 2015). A thorough revision is needed to resolve the problematic situation of Diatrypaceae, which includes a mass of misidentified genus/species, as a result of the unstable phylogenetic frame with type materials. ...
In this study, we investigated the diversity of diatrypaceous fungi from six regions in China based on morpho-molecular analyses of combined ITS and tub2 gene regions. We accept 23 genera in Diatrypaceae with 18 genera involved in the phylogram, and the other five genera are lacking living materials with sequences data. Eleven species included in four genera (viz. Allocryptovalsa, Diatrype, Diatrypella, and Eutypella) have been isolated from seven host species, of which nine novel species (viz. Allocryptovalsa castaneae, A. castaneicola, Diatrype betulae, D. castaneicola, D. quercicola, Diatrypella betulae, Da. betulicola, Da. hubeiensis, and Da. shennongensis), a known species of Diatrypella favacea, and a new record of Eutypella citricola from the host genus Morus are included. Current results show the high diversity of Diatrypaceae which are wood-inhabiting fungi in China.
... However, recent phylogenetic studies indicate that the number of ascospores may not be a reliable taxonomic feature for genera in the Diatrypaceae. These studies have also shown that species taxonomically identified as Diatrype and Diatrypella cannot be consistently separated based on phylogenetic analysis (Chacón et al. 2013;Trouillas et al. 2011;Vasilyeva and Stephenson 2005). ...
Ambrosia beetles in the subtribe Hyorrhynchini are one example of an entire ambrosia beetle lineage whose fungi have never been studied. Here, we identify one dominant fungus associated with a widespread Asian hyorrhynchine beetle Sueus niisimai. This fungus was consistently isolated from beetle galleries from multiple collections. Phylogenetic analyses of combined ITS rDNA and β-tubulin sequences identified the primary fungal symbiont as Diatrypella japonica Higuchi, Nikaido & Hattori (Diatrypaceae, Xylariales, Sordariomycetes), which was recently described as a pathogen of sycamore (Platanus spp.) in Japan. To assess the invasion potential of this beetle-fungus interaction into the US, we have investigated the pathogenicity of two Diatrypella japonica strains on four species of healthy landscape trees native to the southeastern United States. Only Shumard oak (Quercus shumardii) responded with lesions significantly greater than the control inoculations, but there was no observable dieback or tree mortality. Although disease symptoms were not as prominent as in previous studies of the same fungus in Japan, routine re-isolation from the inoculation point suggests that this species is capable of colonizing healthy sapwood of several tree species. Our study shows that the geographical area of its distribution is broader in Asia and potentially includes many hosts of its polyphagous vector. We conclude that the Sueus-Diatrypella symbiosis has high invasion potential but low damage potential, at least on young trees during the growing season.
... Within the family Diatrypaceae, species delimitation is difficult due to the morphological similarity among species (Glawe and Rogers 1984;Rappaz 1987). Therefore, molecular analyses have been recently applied to elucidate the taxonomy and phylogeny of the Diatrypaceae, mostly based on ITS and β-tubulin sequence data (Acero et al. 2004;Carmarán et al. 2009;Trouillas et al. 2010aTrouillas et al. , 2010bTrouillas et al. , 2011Luque et al. 2012;Chacón et al. 2013;Mehrabi et al. 2015;Dayarathne et al. 2016;de Almeida et al. 2016;Mehrabi et al. 2016;Shang et al. 2017). ...
... Eutypella quercina resembles E. semicircularis and E. cerviculata by stromata characteristics (i.e., color, size, and number of perithecia) and ascospore size. However, E. semicircularis, occurring on Alnus acuminata Kunth, is differentiated from E. quercina by having sulcate ostioles, urn-shaped asci with longer stipe (up to 130 μm) and wider spore-bearing part (10-15 vs. 5-7 μm), and strongly curved ascospores (Chacón et al. 2013). Eutypella cerviculata also differs from E. quercina by having sulcate and wider ostioles and amyloid asci (Rappaz 1987). ...
We describe two new species of Eutypella, E. persica from dead branch of Alnus sp. inGuilan province, and E. quercina from dead branch of Quercus sp. in East Azerbaijanprovince of Iran, using morphological and molecular data. Eutypella persica has largestromata with 20–70 perithecia in a valsoid arrangement, sulcate to smooth ostioles,and produces an asexual structure on both natural substrate and culture media.Eutypella quercina, lacking the asexual structure, is characterized by mostly circularstromata with 10–50 perithecia in a valsoid arrangement and smooth ostioles.Phylogenetic relationships of Eutypella with other genera of the Diatrypaceae are hereinferred using maximum parsimony and neighbor-joining analyses of the ITS rDNA andpartial β-tubulin gene. The new combination, Peroneutypa iranica, is proposed basedon morphological features.
... (Glawe and Rogers 1984;Wijayawardene et al. 2012;de Almeida et al. 2016;Mehrabi et al. 2016). Previous phylogenetic studies in Diatrypaceae have been based on combined ITS and β-tubulin (β-tub) sequence data (Acero et al. 2004;Trouillas and Gubler 2004;Carmarán et al. 2009;Trouillas et al. 2010bTrouillas et al. , 2011Luque et al. 2012;Chacón et al. 2013;Mehrabi et al. 2015;Dayarathne et al. 2016;de Almeida et al. 2016;Mehrabi et al. 2016). The natural placements of some genera could not be resolved and, therefore, more taxon sampling and molecular data of selected genes are needed to clarify their natural affinities. ...
... Species of Diatrypaceae are predominantly saprotrophic on the bark of angiosperms, while a few have been reported as pathogens (Trouillas and Gubler 2004;Trouillas et al. 2011) or endophytes in petioles (Carroll et al. 1977) and woody tissue (de Errasti et al. 2010). They are also present in various ecological niches as decomposers on dead wood worldwide (Chacón et al. 2013). ...
Two novel species of Diatrypaceae, Diatrypella tectonae and Peroneutypa mackenziei, were collected from dead wood in northern Thailand. The new species are introduced in this paper, with evidence from morphology and phylogenetic analyses. The new taxa are described, illustrated and compared with related taxa. Phylogenetic analyses of combined ITS and partial β-tubulin (β-tub) sequence data support their natural placements in the genera Diatrypella and Peroneutypa as new species. © 2017 German Mycological Society and Springer-Verlag Berlin Heidelberg
... Three taxa of Xylariaceae were used as outgroups in the ITS dataset and two in the β-tubulin and combined datasets. The multiple alignment program MUSCLE® was implemented using Seaview 4.4 (Gouy et al. 2010) to align the ITS and β-tubulin sequences generated in this study (Table 1) with sequences available in GenBank (Table 2), mainly those from previously published studies on Diatrypaceae (Acero et al. 2004;Rolshausen et al. 2006b;Trouillas et al. 2010bTrouillas et al. , 2011Chacon et al. 2013;Grassi et al. 2014). Alignments were manually corrected using Mesquite 3 (Maddison and Maddison 2014). ...
... Geographical distribution: Brazil. Notes: Only nine species of Diatrypaceae have distinctly urn-shaped asci (Carmarán et al. 2006;Chacon et al. 2013 (Berlese 1900;Rappaz 1987), but, in contrast to P. diminutispora, it extends to connect near the pustules. They also differ from P. diminutispora by having sulcate ostioles and longer part spore regions (15-25 and 18-28 μm, respectively) with amyloid apical rings. ...
Members of the Diatrypaceae are predominantly saprotrophic on the decaying wood of angiosperms worldwide and the family has received little attention due to its difficult taxonomy. However, the recent detection of several pathogenic species, once considered saprotrophic, associated with the wood of diseased grapevines has increased interest in this family. The diversity of tropical species is less well known and more poorly sampled in phylogenetic studies than temperate species. In the present study, we investigated the diversity of diatrypaceous fungi from three areas in the Brazilian semi-arid region and performed phylogenetic analyses of the family based on the entire internal transcribed spacer (ITS) region and partial ß-tubulin gene. Twenty-eight new ITS and 19 new ß-tubulin sequences were generated, representing eight species distributed in five clades. Diatrypella atlantica, Eutypa guttulata, Eutypella cearensis, and Peroneutypa diminutispora are proposed here as new species, while Eutypella microtheca and P. curvispora are new records for Brazil. All eight species are described, illustrated, and discussed.
... The phylogenetic relationships within Diatrypaceae are not well resolved due to poor taxon sampling and lack of adequate sequence data. Most previous phylogenetic studies of this family were based on the ribosomal internal transcribed spacer region (ITS) and partial sequence of the β-tubulin gene (Acero et al. 2004, Carmarán et al. 2009, Trouillas & Gubler 2010, Trouillas et al. 2010a, 2010b, 2011, Luque et al. 2012, Chacón et al. 2013. These studies suggest that the current taxonomic scheme for the Diatrypaceae may not reflect the true phylogenetic relationship. ...
Descriptions and illustrations are provided for six diatrypaceous species from Iran. Diatrypella macrospora is introduced as new to science. It differs from all other Diatrypella species by its larger ascospores. New records for the Iranian mycota include Cryptovalsa rabenhorstii, Eutypella citricola, Peroneutypa scoparia and Quaternaria quaternata. Descriptions and illustrations of microscopic characters, ITS sequence data and taxonomic notes are provided for these newly reported taxa.
... The number of spores per ascus (eight spores versus more than eight spores) has been used traditionally to define genera of Diatrypaceae (Diatrype vs. Diatrypella and Eutype vs. Eutypella). However the polysporous ascus feature has been shown to be not significant in Diatrypaceae based on recent studies (Acero et al. 2004;Vasilyeva and Stephenson 2005;Trouillas et al. 2011;Chacon et al. 2013) and the phylogenies showed that the genera Cryptovalsa and Eutypella, as well as Diatrype and Diatrypella have molecular affinities. Until more species are collected, epitypified and sequenced, as well as an increased sampling of taxa included, the understanding of Diatrypaceae will remain fragmentary. ...
