Didymosphaeria spartii was collected from dead branches of Spartium junceum in Italy. Multi-gene phylogenetic analyses of ITS, 18S and 28S nrDNA sequence data were carried out using maximum likelihood and Bayesian analysis. The resulting phylogenetic trees showed this to be a new genus in a well-supported clade in Massarinaceae. A new genus Pseudod...

... Frame Work and images used for figures were processed with Adobe Photoshop CS3 Extended version 10.0 software. Isolates were derived via single spore isolation following the method of Chomnunti et al. (2014). Ascospore germination were examined after 24 h and germinating spores were transferred to potato dextrose agar (PDA) media. The obtained pure culture was incubated at 25°C in the normal light and the cultural characteristics such as mycelium colour, shape, texture and growth rate were determined. The herbarium specimens of the new genus are deposited in the Mae Fah Luang University Herbarium (MFLU) and New Zealand Fungal & Plant Disease Collection (PDD), while cultures are deposited at the Mae Fah Luang University Culture Collection (MFLUCC) and CBS Netherlands. Fresh fungal mycelium was grown on PDA at 25°C for 21 days. Extraction of genomic DNA from mycelia was carried out following a modified method of Thambugala et al. (2015). Polymerase chain reaction (PCR) was carried out using three partial gene portions in this study. Polymerase chain reaction (PCR) was performed for DNA amplification using the primer combination LROR and LR5 (Vilgalys and Hester, 1990) for the nuclear ribosomal large subunit (LSU); NS1 and NS4 (White et al. 1990) for the nuclear ribosomal small subunit (SSU); ITS4 and ITS5 (White et al. 1990) for the internal transcribed spacer (ITS). The amplifications were performed in 25 μL of PCR mixtures containing 9.5 μL ddH2O, 12.5 μL 2×PCR Master Mix (TIANGEN Co., China), 1 μL of DNA template, 1 μL of each primer (10 μM). Conditions of amplification for all regions were consisted an initial denaturation step of 5 min at 94 °C and final elongation step of 10 minutes at 72 °C. For the SSU and LSU amplification, the 37 cycles consisted of denaturation at 94°C for 1 minute, annealing at 54°C for 50 seconds and elongation at 72°C for 1 minute; for the ITS amplification the 34 cycles consisted of denaturation at 94°C for 30 seconds, annealing at 55°C for 30 seconds and elongation at 72°C for 1 minute. The PCR products were observed on 1% agarose electrophoresis gels stained with Ethidium bromide. Purification and sequencing of PCR products were carried at using the abovementioned PCR primer at Invitrogen Biotechnology Co., China. Sequences generated from LSU, SSU and ITS were identified by BLAST analysis in the GenBank database at the National Centre for Biotechnology Information (NCBI) and sequences were analyzed with other sequences obtained from GenBank (Table 1). Most reliable sequences for taxa in Massarinaceae and representative taxa in Didymosphaeriaceae and Lentitheciaceae were included (Ariyawansa et al. 2014a; Hyde et al. 2013; Zhang et al. 2012). Pleospora herbarum (CBS 191.86) was selected as the out group taxon. The sequence data were aligned and combined using Bioedit (Hall 1999) and MEGA 5.0 (Tamura et al. 2011) and refined visually. The phylogenetic analysis consisted of two methods: The maximum likelihood analysis was performed at the CIPRES webportal using RAxML v.7.2.8 as part of the “RAxML-HPC2 on TG” tool (Stamatakis et al. 2008). The general time reversible model (GTR) using proportion of invariable sites was applied with a discrete gamma distribution and four rate classes. The best scoring tree was selected with a final likelihood value of -8232.350286. Bayesian analysis was performed using MrBayes v. 3.0b4 (Ronquist and Huelsenbeck 2003). The nucleotide substitution models were determined with MrModeltest v. 2.2 (Nylander 2004). Posterior probabilities (PP) (Rannala and Yang 1996; Zhaxybayeva and Gogarten 2002) were defined by Bayesian Markov Chain Monte Carlo (BMCMC) sampling method in MrBayes v. 3.0b4 (Huelsenbeck and Ronquist 2001). Six simultaneous Markov chains were run for 1000000 generations and trees were sampled every 100 th generation resulting in 10000 total trees. 8000 trees were used for calculating posterior probabilities (PP) in the majority rule consensus tree, after discarding the first 2000 trees representing the burn-in phase (20 %) of the analysis. The resulting trees were visualized with TreeView v. 1.6.6 (Page, 1996). The Bayesian posterior probabilities (PP- equal or greater than 0.9) and RAxML bootstrap support values (ML- equal or greater than 50%) are given at the nodes. The sequences generated in this study were deposited in GenBank. Twenty-eight taxa were included in the combined LSU, SSU and ITS data with Pleospora herbarum (CBS 191.86) as the outgroup taxon. Tree topology of the Bayesian analysis (not shown) was almost compatible with the ML tree and the best scoring RAxML tree with a final likelihood value of -8829.280968 is shown in Figure 1. The taxa belonging to families Didymosphaeriaceae, Massarinaceae and Lentitheciaceae separated into three distinct clades. Taxa in Massarinaceae formed five distinct clades. The clades Massarina , Pseudodidymosphaeria and Stagonospora are well-supported and resolved in the phylogenetic tree (Figure 1). Corynespora leucadendri (CBS 135133) clustered in a separate clade, while Byssothecium circinans (CBS 675.92) and Corynespora olivacea (CBS 114450) formed an indistinct sister clade to the Massarina clade. These two clades remain unresolved and need more strains in order to resolve their phylogenetic placement in Massarinaceae. Neottiosporina paspali (CBS 331.37) clustered in Stagonospora clade and may not belong in Neottiosporina but in Stagonospora . Montagnula spartii (CBS 183.58) and our strains (MFLUCC 13–0273 and MFLUCC 14–1212) clustered together and formed a well-supported clade in Massarinaceae (Fig. 1).

... Massarinaceae was considered as a synonym of Lophiostomataceae in some subsequent studies (Barr 1987). However, recent morphological and molecular studies provide evidence that these two families evolved separately (Thambugala et al. 2015). Hence, Massarinaceae and Lophiostomataceae were treated as separate families in the order Pleosporales (Liew et al. 2002, Zhang et al. 2009a, 2012, Hyde et al. 2013, Wijayawardene et al. 2014). ...

In this paper we introduce a new genus Pseudosplanchnonema with P. phorcioides comb. nov., isolated from dead branches of Acer campestre and Morus species. The new genus is confirmed based on morphology and phylogenetic analyses of sequence data. Phylogenetic analyses based on combined LSU and SSU sequence data showed that P. phorcioides formed a distinct clade within the family Massarinaceae and is sister to Massarina eburnea, the type species of Massarina. The new genus Pseudosplanchnonema differs from Massarina in having ascomata without clypei, a thick peridium and larger, 1-septate, guttulate, dark brown ascospores. The new genus is compared with genera in the family Massarinaceae and a detailed description and illustrations of the species P. phorcioides, including its asexual morph, is provided.

Five-hundred and twenty-three (535) notes are provided for newly introduced taxa and for changes that have been made since the previous outline. In the discussion, the latest taxonomic changes in Basidiomycota are provided and the classification of Mycosphaerellales are broadly discussed. Genera listed in Mycosphaerellaceae have been confirmed by DNA sequence analyses, while doubtful genera (DNA sequences being unavailable but traditionally accommodated in Mycosphaerellaceae) are listed in the discussion. Problematic genera in Glomeromycota are also discussed based on phylogenetic results.

This is a continuity of a series of taxonomic and phylogenetic papers on the fungi where materials were collected from many countries, examined and described. In addition to extensive morphological descriptions and appropriate asexual and sexual connections, DNA sequence data are also analysed from concatenated datasets to infer phylogenetic relationships and substantiate systematic positions of taxa within appropriate ranks. Wherever new species or combinations are proposed, we apply an integrative approach using morphological and molecular data as well as ecological features wherever applicable. Notes on 112 fungal taxa are compiled in this paper including Biatriosporaceae and Roussoellaceae, Didysimulans gen. nov., 81 new species, 18 new host records and new country records, five reference specimens, two new combinations, and three sexual and asexual morph reports.
