Teleomorph –anamorph connection of Macalpinomyces spermophorus with Pseudozyma tsukubaensis and corresponding erythritol production
Publication date: Available online 26 July 2017 Source:Mycoscience Author(s): Eiji Tanaka, Yuji Honda A basidiomycetous yeast, Pseudozyma tsukubaensis, has been isolated from a variety of plant materials. Previous molecular phylogenetic analyses have suggested this yeast is an asexual stage of the smut fungus Macalpinomyces spermophorus (synonym Ustilago spermophora, Ustilaginales). To reveal the teleomorph–anamorph connection, yeast-like isolates from germinated teliospores of morphologically identified M. spermophorus on Eragrostis ferruginea from Japan were analyzed. The internal transcribed spacer region of rDNA ...

Species diversity of the entomopathogenic fungi Metarhizium anisopliae and M. flavoviride species complexes isolated from insects in Japan
Publication date: Available online 23 July 2017 Source:Mycoscience Author(s): Oumi Nishi, Hiroki Sato Phylogenetic analyses of insect-derived isolates of the Metarhizium anisopliae and M. flavoviride species complexes in Japan were conducted to reveal their species diversity. Fifty-seven isolates were identified as nine species, including one species first reported for Japan. Metarhizium pingshaense was the most frequently isolated species from this genus, and the 29 isolates of M. pingshaense came from six orders and 14 families of insects. New host–pathogen associations were found for two species with relatively na...

A new species and two new records of Strigula (lichenized Ascomycota) from China
Publication date: Available online 13 July 2017 Source:Mycoscience Author(s): Shu-Hua Jiang, Xin-Li Wei, Jiang-Chun Wei Strigula has traditionally been circumscribed based on morphology, but species delimitation in the genus generally lacks comprehensive analyses. Molecular approach has now been applied to foliicolous material of the genus from tropical areas in China. On the basis of combined phenotype and genotype, Strigula univelbiserialis is described as a new species and Strigula delicata, S. janeirensis are reported as two new records in China.

Phylogeny and taxonomy of Erysiphe pulchra (Erysiphales) and E. cornicola nom. nov.
Publication date: Available online 8 July 2017 Source:Mycoscience Author(s): Jamjan Meeboon, Susumu Takamatsu Cornus spp. are commonly cultivated in parks or gardens as ornamental plants. Powdery mildew is one of the most important diseases of these plant species. Molecular phylogenetic analyses of the causal agent Erysiphe pulchra showed that this species is divided into two genetic groups, viz. one found on C. florida and C. kousa, and another one on C. controversa, both apart from each other. Combined with detailed morphological examinations, E. pulchra s. str. and E. cornicola nom. nov. are proposed for the respe...

Intraspecific variation in mycelial growth of Cenococcum geophilum isolates in response to salinity gradients
Publication date: Available online 6 July 2017 Source:Mycoscience Author(s): Yosuke Matsuda, Mai Yamakawa, Tomomi Inaba, Keisuke Obase, Shin-ichiro Ito Although interspecific variation in the response of ectomycorrhizal fungi to salinity has been examined, knowledge of the intraspecific variation is limited. We evaluated the salinity tolerance of Cenococcum geophilum isolated from ectomycorrhizal roots of Japanese black pine (Pinus thunbergii) from eight coastal pine forests in Japan. The identity of the obtained isolates was ensured by DNA sequencing of the internal transcribed spacer region. Mycelial growth of 56 ...

Two novel Tuber species (Tuberaceae, Pezizales) in the Latisporum Group from China
Publication date: Available online 2 June 2017 Source:Mycoscience Author(s): Shan-Ping Wan, Li Tang, Yi Zheng, Fu-Qiang Yu Recent taxonomic and molecular studies on Tuber in China have revealed several new species. Here we propose Tuber polymorphosporum and T. baoshanense as new species. These species are described from Yunnan Province and differ in a combination of morphological features including ascoma color, peridium structure and ascospore shape and size. These two new taxa have phylogenetic affinity to T. latisporum and T. alboumbilicum, respectively, described from the southwest China. Phylogenetic placements ...

Life cycle of Aecidium klugkistianum on Ligustrum and its new combination, Puccinia klugkistiana
Publication date: Available online 25 May 2017 Source:Mycoscience Author(s): Jing-Xin Ji, Zhuang Li, Qi Wang, Yu Li, Makoto Kakishima During the survey of rust fungi in Jilin Province, China, we found Ligustrum obtusifolium (Oleaceae) heavily infected with a rust fungus, Aecidium klugkistianum in the Changchun area. The life cycle of A. klugkistianum was elucidated via field observations and inoculation experiments. This rust fungus produces uredinial and telial stages on Cleistogenes hackelii (Gramineae). These stages morphologically belong to Puccinia and are different from other fungi on Cleistogenes in terms of ...

Publication date: Available online 24 May 2017 Source:Mycoscience Author(s): Yuka Yajima, Tamotsu Hoshino, Norio Kondo, Young-Cheol Chang The plasmodium of Badhamia alpina thrived at lower temperatures (4 °C), and formed fruiting bodies at 8 °C. The yellow sclerotium and plasmodium were found inside a hollow, dead herbaceous stem under melting snow in Apr, and was cultured in moist chambers at 4 °C. The plasmodium did not form fruiting bodies for 6 wk at 4 °C. Sporulation was observed after the incubation temperatures rose to 8 °C. Sporulation occurred in the morning and cell cleavage at 11 a.m. The order...

Molecular phylogeny and taxonomy of Parauncinula (Erysiphales) and two new species P. polyspora and P. uncinata
Publication date: Available online 22 May 2017 Source:Mycoscience Author(s): Jamjan Meeboon, Siska A.S. Siahaan, Kayoko Fujioka, Susumu Takamatsu Parauncinula, a genus belonging to the Erysiphaceae (powdery mildew family), consisted of only two species, P. curvispora and P. septata, which are distributed only in China and Japan (endemic to East Asia). This genus split from other powdery mildew genera at an early stage of evolution, and thus has been considered as one of the most ancestral genera in the Erysiphales. Phylogenetic analyses using rDNA internal transcribed spacer (ITS) region and 28S rRNA gene sequences i...
