It was first isolated from the trunk of a mono maple tree (Acer mono) in the Shirakami-Sanchi forest region of Japan. The species was named after the Acer tree genus from which it was isolated.

The optimum growth temperature for R. aceris is 30 °C, but can grow in the 10-35 °C range. The optimum pH is 7.0, and can grow in pH 6.0-9.0.
