The ultrastructure of the zoosporic, rumen fungal anaerobe, Neocallimastix sp. R1, was determined and compared to that of the two known species of Neocallimastix. Zoospores of the new isolate were generally ovoid in shape, but without the waisted appearance of N. frontalis zoospores. They possessed similar organelles to the other two species, but with different localisation. The flagellar rootlet system was broadly similar to N. frontalis and N. patriciarum, however, a previously undescribed, large organelle was found to be associated near the kinetosomal apparatus in some Neocallimastix sp. R1 zoospores. Well developed flagella, complete with basal bodies, were observed in young thalli.
对游动孢子型瘤胃真菌厌氧菌新丽鞭毛菌属（Neocallimastix）的R1菌株进行了超微结构测定，并与新丽鞭毛菌属已知的两个物种进行了比较。新分离菌株的游动孢子通常呈卵形，但没有前额新丽鞭毛菌游动孢子的束腰外观。它们拥有与其他两个物种相似的细胞器，但定位不同。鞭毛根系统与前额新丽鞭毛菌和帕特里克新丽鞭毛菌大致相似，然而，在一些新丽鞭毛菌属R1菌株的游动孢子中，发现一种以前未描述的大型细胞器与动基体装置附近有关联。在幼嫩菌体中观察到发育良好的鞭毛，连同基体。
