近20年来对壶菌门的分子和超微结构研究导致了包括根菌门在内的新目的分离。这一目的大多数种在形态上相似，具有单心的、圆心的球形菌体。本文通过对其18S和28S rDNA的分析，将新属和新种添加到该目中。这种濒临死亡的水生植物叶片的标本是该目中已知的第一个根茎菌丝物种。在我们的分子系统发育中，P。与两栖类病原体水蛭壶菌（batrachochytriium dendroatid）和b。这使得研究与宿主转换和形态适应相关的进化途径的研究人员特别感兴趣。
Molecular and ultrastructural investigations of the Chytridiomycota during the last 20 years have led to the separation of new orders, including the Rhizophydiales. Most species in this order are morphologically similar, possessing monocentric, eucarpic, spherical thalli. Here, based on analysis of nuc 18S and 28S rDNA, we add the new genus and speciesPolyrhizophydium stewartiito the order. This saprobe of moribund aquatic plant leaves is the first known rhizomycelial species in the order. In our molecular phylogeny,P. stewartiigroups with the amphibian pathogensBatrachochytriuim dendrobatidisandB. salamandrivorans, making it of particular interest to investigators studying evolutionary pathways associated with host-switching and morphological adaptation.
