Fallacia属，由Stickle和Mann(圆形等人)建立。1990)，包括许多以前属于螺旋藻属的小种。Fallacia属植物的特征是具有单一的H型叶绿体、中断纹状体的侧胸骨和完全或部分覆盖纹状体的疏松的漏斗。在光学显微镜下观察，侧方凹陷的胸骨在瓣膜面上显示侧方透明区域。这些侧面的透明区域也存在于莱里拉物种中，然而，它们缺乏孔洞细密的圆锥体。现在有超过100种的属(Guary M.D.和Guary G.M.2013中的GuailM.D.)。最近提出了一个新属--假尿囊霉(Pseudofallacia)。2012年)。假水仙属与水仙草属有一些相同的特征，如在中缝两侧都有横向的纵向沟渠，孔洞覆盖在这些沟渠上。相反，假性软化症的管子不是由凹陷的胸骨中断纹组成，而是由瓣膜的初级硅层沿中缝凹陷的一部分组成。假纤毛中的条纹是每条纹一个大的圆形到拉长的乳晕，而不是几个微小的乳晕。由于凹陷的侧胸骨、乳晕和圆锥体只能用电子显微镜观察，因此需要详细审查分类群才能正确地鉴定它们。根据阿拉斯加巴罗罗杰斯-波斯特纪念碑的材料，首次描述了纳维特拉·霍奇纳·帕特里克和弗里斯(1961)。该物种生活在淡水到微咸水环境中。正模标本采集自南瓜(硅藻)的形态和超微结构
The genus Fallacia, established by Stickle and Mann (Round et al. 1990), includes many small species that previously belonged to the genus Navicula Bory sensu lato. The genus Fallacia is characterized by a single H-shaped plastid, lateral sterna interrupting striae and finely porous conopeum completely and partly covering striae. The lateral depressed sterna exhibit lateral hyaline areas on the valve face, when observed by light microscope. Those lateral hyaline areas also present in Lyrella species, however, they lack the finely porous conopeum. Now there are over 100 species in the genus Fallacia (Guiry M. D. in Guiry M. D. and Guiry G. M. 2013). Recently a new genus Pseudofallacia was proposed (Liu et al. 2012). The genus Pseudofallacia shares some features with Fallacia, such as lateral longitudinal canals on either side of raphe, and finely porous conopea covers those canals. In contrast, the canals in Pseudofallacia were not composed by a depressed sternum interrupting striae, but a depressed part of the primary silica layer of valve along the raphe. The striae in Pseudofallacia are one large round to elongate areola per striae rather than several tiny areolae. Since the depressed lateral sterna, areolae and conopeum could only be observed by using electron microscopy is needed to review taxa in detail in order to identify them properly. Navicula hodgeana Patrick & Freese (1961) was first described based on the material from Rogers-Post Monument, Barrow, Alaska second judicial division. The species lives in fresh to brackish water environment. The holotype specimen was collected from scrapings of Morphology and Ultrastructure of Fallacia hodgeana (Bacillariophyceae)
