Overview |
Maintained on oak bark agar (pH 7.2) at room temperature. An unidentified bacterium isolated from the original substrate was used as food either alone or in combination with a variety of Aureobasidium pullulans. Sporocarps 45-70 µm tall. Stalks have a knob-like apophysis at the top. Sporangia are 4-spored, with spores are arranged in a tetrad. The spore attached to the stalk distinctly conical in shape. There is a distinct hilum at the base of the sporangium which is visible under electron microscopy. Spores dimensions are (10-) 12.5-15 (-16.25) x (10.6-) 11.25 x 12.5µm. Each spore gives rise a uninucleate amoeba with soon becomes flagellated. This flagellate rounds up, withdraws its flagella and divides to form two flagellate cells after germination. In this way eight flagellate cells are derived from one sporangium. A vermiform stage has not been observed in this species. Cysts are spherical to ellipsoidal, 2.5-18.75 µm in diam.
