  1. Measurements were from 3 d and 14 d cells of Protomyces species. Yeast cells were cultured in YPG agar plates. Cell images were captured by LEICA 2500 microscope with a LEICA DFC490 camera. Cell length and width were measured with imageJ software. Two independent cultures were applied in the statistics, with around 100 cells sampled in each biological repeat. The yeast cells of P. arabidopsidicola had a significantly shorter length than its closest relative P. inouyei (p < 0.05) by one way ANOVA + Tukey HSD. NA: not available. “Reference*”: is the published size range for each species according to Kurtzman (2011).
