Mortierella sugadairana, a new homothallic species related to the firstly described heterothallic species in the genus

Publication date: May 2018Source: Mycoscience, Volume 59, Issue 3Author(s): Yusuke Takashima, Yousuke Degawa, Hiroyuki Ohta, Kazuhiko NarisawaAbstractA new species, Mortierella sugadairana, is described for a fungus forming homothallic zygospores with a club-shaped macrosuspensor and a microsuspensor originating from the macrosuspensor. The species was isolated from cool regions in Japan and morphologically and phylogenetically close to a heterothallic species M. parvispora, which is the first species reported as a heterothallic species in the genus. Mycelial growth of the species was limited at 30 °C, whereas two isolates of M. parvispora can grow. This may indicate that the species and M. parvispora adapted to different climates from a common ancestor involving differentiation of the manner of reproduction.
