描述了两种新的食菌性土壤纤毛虫的形态和纤毛。用非浸泡培养皿方法从干燥、再湿的土壤样品中分离样品，并用各种银浸渍技术进行活体研究。FungiPhyra strobli n.g，n.sp.是在南非共和国桌山顶峰的岩池泥浆中被发现的。它是一种全毛状纤毛虫，大小约为50×40亩，口腔器官位于细胞的右侧。具腺纤毛，在该群的所有其他成员中微小：发育良好，平均有8个动点，形成明显的左侧口部多动点，非常类似于在尾足动物属的小物种中发现的。喷出的突出体有一个独特的、充气的远端。卵形巨藻Grossglockneria ovata n.sp.是在美国宾夕法尼亚州拉卡万纳州立森林的落叶中发现的。它与该属其他成员的不同之处在于卵形、光滑的皮质和稀疏的、不规则形状的粘液囊。讨论了罗汉果属的分类特征和分类地位。由于与独特的摄食策略--真菌吞噬有关的复杂而独特的饲养管，有人认为巨型纤毛虫应该被归类在一个单独的目中，尽管它们与鞘翅目的成员有密切的遗传关系。
The morphology and infraciliature of two new, mycophagous soil ciliates are described. Specimens were isolated from dried, rewetted soil samples with the non-flooded Petri dish method and investigated in vivo and with various silver impregnation techniques. Fungiphyra strobli n. g., n. sp. was discovered in the mud of rock-pools on the summit of Table Mountain, Republic of South Africa. It is a holotrichously ciliated, about 50 x 40 mu m-sized grossglockneriid with the oral apparatus on the right side of the cell. The adoral ciliature, minute in all other members of the group: is well developed and has a mean of eight kineties forming a conspicuous left, oral polykinetid, highly reminiscent of that found in small species of the genus Colpoda. The ejected extrusomes have a unique, inflated distal end. Grossglockneria ovata n. sp. was discovered in leaf litter from the Lackawanna State Forest in Pennsylvania, USA. It differs from the other members of the genus by the ovate shape, smooth cortex, and the sparse, irregularly-shaped mucocysts. Taxonomic characters and ranking of grossglockneriids are discussed. Because of the complex, unique feeding tube associated with a unique feeding strategy, mycophagy, it is argued that grossglockneriid ciliates should be classified in a separate order, in spite of their close genetic relatedness to members of the order Colpodida.
