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. The new species are Amanita cornelii, A. emodotrygon, Angustimassarina alni, A. arezzoensis, A. italica, A. lonicerae, A. premilcurensis, Ascochyta italica, A. rosae, Austroboletus appendiculatus, Barriopsis thailandica, Berkleasmium ariense, Calophoma petasitis, Camarosporium laburnicola, C. moricola, C. grisea, C. ossea, C. paraincrustata, Colletotrichum sambucicola, Coprinopsis cerkezii, Cytospora gelida, Dacrymyces chiangraiensis, Didysimulans italica, D. mezzanensis, Entodesmium italica, Entoloma magnum, Evlachovaea indica, Exophiala italica, Favolus gracilisporus, Femsjonia monospora, Fomitopsis flabellata, F. roseoalba, Gongronella brasiliensis, Helvella crispoides, Hermatomyces chiangmaiensis, H. chromolaenae, Hysterium centramurum, Inflatispora caryotae, Inocybe brunneosquamulosa, I. luteobrunnea, I. rubrobrunnea, Keissleriella cirsii, Lepiota cylindrocystidia, L. flavocarpa, L. maerimensis, Lophiotrema guttulata, Marasmius luculentus, Morenoina calamicola, Moelleriella thanathonensis, Mucor stercorarius, Myrmecridium fluviae, Myrothecium septentrionale, Neosetophoma garethjonesii, Nigrograna cangshanensis, Nodulosphaeria guttulatum, N. multiseptata, N. sambuci, Panus subfasciatus, Paraleptosphaeria padi, Paraphaeosphaeria viciae, Parathyridaria robiniae, Penicillium punicae, Phaeosphaeria calamicola, Phaeosphaeriopsis yuccae, Pleurophoma italica, Polyporus brevibasidiosus, P. koreanus, P. orientivarius, P. parvovarius, P. subdictyopus, P. ulleungus, Pseudoasteromassaria spadicea, Rosellinia mearnsii, Rubroboletus demonensis, Russula yanheensis, Sigarispora muriformis, Sillia italica, Stagonosporopsis ailanthicola, Strobilomyces longistipitatus, Subplenodomus galicola and Wolfiporia pseudococos. The new combinations are Melanomma populina and Rubroboletus eastwoodiae. The reference specimens are Cookeina tricholoma, Gnomoniopsis sanguisorbae, Helvella costifera, Polythrincium trifolii and Russula virescens. The new host records and country records are Ascochyta medicaginicola, Boletellus emodensis, Cyptotrama asprata, Cytospora ceratosperma, Favolaschia auriscalpium, F. manipularis, Hysterobrevium mori, Lentinus sajor-caju, L. squarrosulus, L. velutinus, Leucocoprinus cretaceus, Lophiotrema vagabundum, Nothophoma quercina, Platystomum rosae, Pseudodidymosphaeria phlei, Tremella fuciformis, Truncatella spartii and Vaginatispora appendiculata and three sexual and asexual morphs are Aposphaeria corallinolutea, Dothiora buxi and Hypocrella calendulina.
Neoleptosphaeria is a genus of ascomycetes known only from its asexual morphs (coelomycetous) and its species have saprobic and/or endophytic life modes. We obtained LSU, SSU and ITS sequence data from a single spore isolation of a freshly collected specimen. A phylogeny of representative strains of the genus and other taxa in Leptosphaeriaceae was obtained. Neoleptosphaeria proved to be strongly monophyletic but related to other genera in Leptosphaeriaceae. Phylogenetic analyses place our new isolate in a strongly supported clade with the generic type of Neoleptosphaeria (N. rubefaciens). The sexual morph of Neoleptosphaeria is therefore established and includes the first genus with muriform ascospores in Leptosphaeriaceae.
Celtis occidentalis (American hackberry) is a deciduous tree widely distributed in northern America and introduced in many regions of Europe. In this study we collected Cucurbitaria celtidis from dead or dying twigs and branches of C. occidentalis (Cannabaceae) in the Rostov region (Southern European Russia), where this tree is a common ergasiophyte in artificial forests. The placement of this species in Camarosporium sensu stricto in Pleosporinae, Pleosporales is shown in a multi-locus tree based on combined LSU, SSU and ITS sequence data. Camarosporium uniseriatum nom. nov. is introduced based on morphological and phylogenetic analyses.
