(Phaeoseptaceae, Pleosporales) from China. Mycosphere 10(1), 757–775, Doi 10.5943/mycosphere/10/1/17 Abstract A new hyphomycete genus, Pleopunctum, is introduced to accommodate two new species, P. ellipsoideum sp. nov. (type species) and P. pseudoellipsoideum sp. nov., collected from decaying wood in Guizhou Province, China. The genus is characterized by macronematous, mononematous conidiophores, monoblastic conidiogenous cells and muriform, oval to ellipsoidal conidia often with a hyaline, elliptical to globose basal cell. Phylogenetic analyses of combined LSU, SSU, ITS and TEF1α sequence data of 55 taxa were carried out to infer their phylogenetic relationships. The new taxa formed a well-supported subclade in the family Phaeoseptaceae and basal to Lignosphaeria and Thyridaria macrostomoides. -

The family is typified by Melansporella gen. nov. It can be distinguished from other diaporthalean families based on its irregularly uniseriate ascospores, and ovoid, brown conidia with a hyaline sheath and surface structures. Phylogenetic analysis shows that Melansporella juglandium sp. nov. forms a monophyletic group within Diaporthales (MP/ML/BI=100/96/1) and is a new diaporthalean clade, based on molecular data of ITS and LSU gene re- gions. Thus, a new family is proposed to accommodate this taxon. Key words: diaporthalean fungi, fungal diversity, new taxon, Sordariomycetes, systematics, taxonomy Introduction The ascomycetous order Diaporthales (Sordariomycetes) are well-known fungal plant pathogens, endophytes and saprobes, with wide distributions and broad host ranges (Castlebury et al. 2002, Rossman et al. 2007, Maharachchikumbura et al. 2016). -

MycoKeys 65: 119–138. https://doi.org/10.3897/mycokeys.65.49769 Abstract Lignicolous freshwater fungi represent one of the largest groups of Ascomycota. This taxonomically highly diverse group plays an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning. The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient is cur- rently being studied in Asia. -
Fungicide Sensitivity of Corynespora Cassiicola and Assessment Of
FUNGICIDE SENSITIVITY OF CORYNESPORA CASSIICOLA AND ASSESSMENT OF MANAGEMENT OF TARGET SPOT OF COTTON IN GEORGIA by: MA. KATRINA SHIELA E. LAUREL (Under the Direction of Robert C. Kemerait, Jr.) ABSTRACT Target spot, caused by Corynespora cassiicola, is a serious foliar disease of cotton in the southeastern United States. Baseline (current) isolates of C. cassiicola were tested for sensitivity to metconazole (DMI), fluxapyroxad (SDHI) and pyraclostrobin (QoI). Further work compared fungicide sensitivity of C. cassiicola isolates from cotton to isolates from other hosts. Field experiments were conducted to establish a relationship between fungicide sensitivity in laboratory experiments and fungicide efficacy in managing target spot on cotton. Based on the sensitivity distribution, all isolates tested were considered sensitive to fungicides. However, these sensitivities varied among isolates offering an early indication that resistance can happen in the future. Additionally, all fungicides reduced disease severity and premature defoliation; however, Priaxor (pyraclostrobin + fluxapyroxad [QoI + SDHI]) proved to be most effective. Results from this study can help optimize fungicide sensitivity monitoring practices in an effort to improve fungicide use patterns for optimum disease management.

Gen. Nov. on <I> Juglandaceae</I>, and the New Family
Persoonia 38, 2017: 136–155 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/003158517X694768 Juglanconis gen. nov. on Juglandaceae, and the new family Juglanconidaceae (Diaporthales) H. Voglmayr1, L.A. Castlebury2, W.M. Jaklitsch1,3 Key words Abstract Molecular phylogenetic analyses of ITS-LSU rDNA sequence data demonstrate that Melanconis species occurring on Juglandaceae are phylogenetically distinct from Melanconis s.str., and therefore the new genus Juglan- Ascomycota conis is described. Morphologically, the genus Juglanconis differs from Melanconis by light to dark brown conidia with Diaporthales irregular verrucae on the inner surface of the conidial wall, while in Melanconis s.str. they are smooth. Juglanconis molecular phylogeny forms a separate clade not affiliated with a described family of Diaporthales, and the family Juglanconidaceae is new species introduced to accommodate it. Data of macro- and microscopic morphology and phylogenetic multilocus analyses pathogen of partial nuSSU-ITS-LSU rDNA, cal, his, ms204, rpb1, rpb2, tef1 and tub2 sequences revealed four distinct species systematics of Juglanconis. Comparison of the markers revealed that tef1 introns are the best performing markers for species delimitation, followed by cal, ms204 and tub2. The ITS, which is the primary barcoding locus for fungi, is amongst the poorest performing markers analysed, due to the comparatively low number of informative characters. Melanconium juglandinum (= Melanconis carthusiana), M. oblongum (= Melanconis juglandis) and M. pterocaryae are formally combined into Juglanconis, and J. appendiculata is described as a new species. Melanconium juglandinum and Melanconis carthusiana are neotypified and M. oblongum and Diaporthe juglandis are lectotypified. A short descrip- tion and illustrations of the holotype of Melanconium ershadii from Pterocarya fraxinifolia are given, but based on morphology it is not considered to belong to Juglanconis. -
