Description: | On pine pollen: Sporangium interbiotic among the pollens, spherical, 12.5-85 μm diam., or subspherical, with several discharge pores, 3 μm diam. Apophysis tubular or bulbous, 5-15μm diam. with extensive rhizoidal system up to 250 μm, tapering to blunt ends.On 1/4 YpSs agar: Sporangium spherical or subspherical, 30-75 μm diam. with 3-10 discharge papillae, 2.5 μm high, 5 μm diam.. Main rhizoidal neck isthmus-like, below tubular, 5-7.5 μm diam., inflated or bulbous, 10-17.5 μm diam.; rhizoids irregularly branched or occasionally somewhat dichotomously branched, even or uneven and tapered to blunt ends. Zoospore globose, 4-5 μm diam., or amoeboid with a conspicious lipid globule; zoospores escaping upon the dissolution of the papillae. Resting spore spherical, about 31 μm diam.; wall smooth, 2.2μm thick. Color of colony white. | |||
