Syncephalastrum contaminatum, a new species in the Mucorales from Australia
Publication date: Available online 22 February 2020Source: MycoscienceAuthor(s): Andrew S. Urquhart, Alexander IdnurmAbstractA new species is described in the Mucorales family Syncephalastraceae: Syncephalastrum contaminatum, isolated as an in vitro culture from a laboratory contaminant. The species has variable copies of the internal transcribed spacer (ITS) regions, requiring cloning of these regions prior to Sanger sequencing before subsequent use in phylogenetic comparisons with other fungi. The genome of the strain was sequenced using short paired-reads to yield a draft genome of 28.6 Mb. Syncephalastrum contaminatu...

Simplicillium spumae (Cordycipitaceae, Hypocreales), a new hyphomycetes from aquarium foam in Japan
Publication date: Available online 16 February 2020Source: MycoscienceAuthor(s): Naozumi Kondo, Hiromu Iwasaki, Toshiyuki Tokiwa, Satoshi Ōmura, Kenichi NonakaAbstractFive Simplicillium isolates were obtained from foam generated in an aquarium in Minato-ku, Tokyo, Japan. Using a combination of micro-morphological characteristics and multigene (ITS, SSU, LSU, TEF) phylogenics, the isolates were identified as S. subtropicum and a new species which were previously undescribed. Simplicillium spumae, which is a new species, differs from known Simplicillium species in the morphology of their conidia and conidiophores. (Source: Mycoscience)

Spore formation and karyological characterization of basidiosporogenesis, meiosis, post-meiotic and nuclear migration mitosis in Coprinus comatus
Publication date: Available online 6 February 2020Source: MycoscienceAuthor(s): Fu-Chia Chen, Norihiro Shimomura, Takeshi Yamaguchi, Tadanori AimiAbstractIn Coprinus comatus, we sampled and observed different maturity stages of basidium to find the possible causes of binucleate basidiospores by microscopy using the HCI-Giemsa and DAPI staining methods. In basidium, following karyogamy, a single nucleolus was observed. We found evidence suggesting post-meiotic mitosis following nuclear migration in the spores. Post-meiotic mitosis occurred in the basidiospores, resulting in four binucleate basidiospores. This indicates that...

Purification and characterization of low molecular weight alkali stable xylanase from Neosartorya spinosa UZ-2-11
Publication date: Available online 31 January 2020Source: MycoscienceAuthor(s): Chollada Somboon, Santhaya Boonrung, Somporn Katekaew, Jindarat Ekprasert, Tadanori Aimi, Sophon BoonlueAbstractAlkaliphilic xylanase from Neosartorya spinosa UZ-2-11 was purified using a three-step of purification scheme of ammonium sulphate precipitation followed by Sephadex G-100 gel filtration and DEAE-cellulose ion-exchange chromatography, and compared its properties with N. tatenoi KKU-CLB-3-2-4-1 of our previous report. The purified xylanase from N. spinosa UZ-2-11 exhibited maximum activity at pH 9.0 and 45 °C which was similar to en...

Assessment of waste frying oil transesterification capacities of local isolated Aspergilli species and mutants
Publication date: Available online 28 January 2020Source: MycoscienceAuthor(s): Nadeem I. Elhussiny, Abd El-Nasser Khattab, Heba A. El-Refai, Sayeda S. Mohamed, Yousseria M. Shetaia, Hala A. AminAbstractBiodiesel (fatty acids methyl esters, FAME) has attracted considerable attention as an environmentally and eco-friendly alternative for diesel engines. This research manipulates the use of Aspergillus whole-cell lipase as a biocatalyst for biodiesel production from waste frying oil (WFO). A total of 17 isolates of Aspergillus species screened for lipase and esterase production abilities. Qualitatively, 11 Aspergillus isolat...

Advances in the cultivation of the highly-prized ectomycorrhizal mushroom Tricholoma matsutake
Publication date: Available online 22 January 2020Source: MycoscienceAuthor(s): Takashi Yamanaka, Akiyoshi Yamada, Hitoshi FurukawaAbstractMatsutake, the fruiting body of Tricholoma matsutake, is among the most economically important edible ectomycorrhizal (EM) mushrooms worldwide. This EM fungus develops “shiros”, which are mycelial aggregations that develop in association with the roots of EM coniferous trees and soil particles in well-drained and nutrient-poor forest soil. The fruiting bodies occur on the periphery of the outward-growing shiro. In spite of vast research, the cultivation of matsutake has been mostly ...

Influence of pH on in vitro mycelial growth in three Japanese truffle species: Tuber japonicum, T. himalayense, and T. longispinosum
Publication date: Available online 19 December 2019Source: MycoscienceAuthor(s): Shota Nakano, Akihiko Kinoshita, Keisuke Obase, Noritaka Nakamura, Hitomi Furusawa, Kyotaro Noguchi, Takashi YamanakaAbstractTruffle species indigenous to Japan include a white-colored truffle Tuber japonicum and two black-colored truffles, T. himalayense and T. longispinosum. As the fruiting bodies of these Tuber species are promising edible, studies on the artificial cultivation for these truffles are currently underway in Japan. In the present study, we investigated the influence of pH on in vitro mycelial growth in these Tuber species to ...

A new species of Pithoascus and first report of this genus as endophyte associated with Ferula ovina
Publication date: Available online 20 January 2020Source: MycoscienceAuthor(s): Zahra Tazik, Kamran Rahnama, Mehrdad Iranshahi, James Francis White, Hassan SoltanlooAbstractA newly described species of Pithoascus from roots of Ferula ovina differs from other Pithoascus species by producing larger ascomata than all described species except P. exsertus. The shape of its ascospores is similar to that of P. lunatus, but differs from it by having an asexual state. This new species differs from P. ater by having a sexual state. Phylogenetic analyses based on concatenated ITS rDNA, LSU rDNA and partial translation elongation fact...

Ochropsora staphyleae, a new rust pathogen of Japanese bladdernut, found in central Japan
Publication date: Available online 29 November 2019Source: MycoscienceAuthor(s): Yoshitaka Ono, Sinchai Chatasiri, Eiji TanakaAbstractJapanese bladdernut shrub, Staphylea bumalda (Staphyleaceae), was found infected by a fungus in Prefectures of Ibaraki and Tochigi, central Japan. The fungus produced telia beneath the host epidermis and basidiospores on metabasidia emerging from the sori on the abaxial leaf surface. Probasidia were single-celled, sessile, short-cylindrical, thin-walled, and laterally free. A four-celled metabasidium arose from a probasidium by apical elongation. Apparent biotrophic nature and the basidium m...
