Lists of Names in Aspergillus and Teleomorphs As Proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (Doi: 10.3852/14-0
Lists of names in Aspergillus and teleomorphs as proposed by Pitt and Taylor, Mycologia, 106: 1051-1062, 2014 (doi: 10.3852/14-060), based on retypification of Aspergillus with A. niger as type species John I. Pitt and John W. Taylor, CSIRO Food and Nutrition, North Ryde, NSW 2113, Australia and Dept of Plant and Microbial Biology, University of California, Berkeley, CA 94720-3102, USA Preamble The lists below set out the nomenclature of Aspergillus and its teleomorphs as they would become on acceptance of a proposal published by Pitt and Taylor (2014) to change the type species of Aspergillus from A. glaucus to A. niger. The central points of the proposal by Pitt and Taylor (2014) are that retypification of Aspergillus on A. niger will make the classification of fungi with Aspergillus anamorphs: i) reflect the great phenotypic diversity in sexual morphology, physiology and ecology of the clades whose species have Aspergillus anamorphs; ii) respect the phylogenetic relationship of these clades to each other and to Penicillium; and iii) preserve the name Aspergillus for the clade that contains the greatest number of economically important species. Specifically, of the 11 teleomorph genera associated with Aspergillus anamorphs, the proposal of Pitt and Taylor (2014) maintains the three major teleomorph genera – Eurotium, Neosartorya and Emericella – together with Chaetosartorya, Hemicarpenteles, Sclerocleista and Warcupiella. Aspergillus is maintained for the important species used industrially and for manufacture of fermented foods, together with all species producing major mycotoxins. The teleomorph genera Fennellia, Petromyces, Neocarpenteles and Neopetromyces are synonymised with Aspergillus. The lists below are based on the List of “Names in Current Use” developed by Pitt and Samson (1993) and those listed in MycoBank (www.MycoBank.org), plus extensive scrutiny of papers publishing new species of Aspergillus and associated teleomorph genera as collected in Index of Fungi (1992-2104). -

Samson, [email protected] Abstract: Section Terrei of Aspergillus was studied using a polyphasic approach including sequence analysis of parts of the β-tubulin and calmodulin genes and the ITS region, macro- and micromorphological analyses and examination of extrolite profiles to describe three new species in this section. Based on phylogenetic analysis of calmodulin and β-tubulin sequences seven lineages were observed among isolates that have previously been treated as A. terreus and its subspecies by Raper & Fennell (1965) and others. Aspergillus alabamensis, A. terreus var. floccosus, A. terreus var. africanus, A. terreus var. aureus, A. hortai and A. terreus NRRL 4017 all represent distinct lineages from the A. terreus clade. Among them, A. terreus var. floccosus, A. terreus NRRL 4017 and A. terreus var. aureus could also be distinguished from A. terreus by using ITS sequence data. New names are proposed for A. terreus var. floccosus, A. terreus var. -

Aspergillus species originating from Greece were examined by morphological and molecular criteria to explore the diversity of this genus. The phylogenetic relationships of these species were determined using sequences from the ITS and IGS region of the nuclear rRNA gene complex, two nuclear genes (-tubulin (benA) and RNA polymerase II second largest subunit (rpb2)) and two mitochondrial genes (small rRNA subunit (rns) and cytochrome oxidase subunit I (cox1)) and, where available, related sequences from databases. The morphological characters of the anamorphs and teleomorphs, and the single gene phylogenetic trees, differentiated and placed the species examined in the well-supported sections of Aenei, Aspergillus, Bispori, Candidi, Circumdati, Clavati, Cremei, Flavi, Flavipedes, Fumigati, Nidulantes, Nigri, Restricti, Terrei, Usti,andZonati, with few uncertainties. -

Received 27 June, 2015; Accepted 12 November, 2015 Aflatoxin contamination impinges on grain quality worldwide. The causative agent, Aspergillus spp. colonizes grain in the field down to postharvest stages in storage where they may produce toxins. Kenya has experienced recurring cases of aflatoxicosis in Eastern region especially during periods of maize grain deficit. The risk of chronic exposure has not been widely studied. Therefore, seasonal variation in abundance and species composition of toxigenic Aspergillus in maize and soils of Eastern Kenya was investigated. Samples were obtained from farmers, two months after the first (May) and second (December) harvest seasons. Aspergillus spp. were isolated from maize and soil samples by direct and dilution plate techniques respectively on Czapek Dox Agar (CZ) and thereafter sub-cultured on potato dextrose agar (PDA). Positive identification was done using culture-morphological and microscopic characteristics in PDA media. The ammonium vapour test was used to screen for the putative toxigenic strains. -

Lyngby, Denmark *Correspondence: R.A. Samson, [email protected] Abstract: Aspergillus comprises a diverse group of species based on morphological, physiological and phylogenetic characters, which significantly impact biotechnology, food production, indoor environments and human health. Aspergillus was traditionally associated with nine teleomorph genera, but phylogenetic data suggest that together with genera such as Polypaecilum, Phialosimplex, Dichotomomyces and Cristaspora, Aspergillus forms a monophyletic clade closely related to Penicillium. Changes in the International Code of Nomenclature for algae, fungi and plants resulted in the move to one name per species, meaning that a decision had to be made whether to keep Aspergillus as one big genus or to split it into several smaller genera. -

Journal of Microbial Systematics and Biotechnology 1(1), 1-10 Abstract Endophytic fungi have been known to play a role in protecting their host plants against diseases and extreme environments. The purpose of this study was to determine the antagonistic activity of three Aspergillus isolates against F. oxysporum f. sp. cubense (Foc), and to identify the Aspergillus identity using multilocus phylogeny analysis. Antagonistic assay by dual culture method showed that the Aspergillus sp. strain PD2, strain PD4, and strain PD5 inhibited the growth of Foc isolate by 37.31%, 26.52%, and 12.04%, respectively. Multilocus phylogeny based on ITS rDNA, beta-tubulin, and calmodulin genes sequences showed that the Aspergillus strain PD2 and strain PD4 belong to A. section Terrei, while the Aspergillus sp. strain PD5 was identified as A. sydowii of the A. sect.
