无层虫（Aphakopsorafungus）是在澳大利亚昆士兰州北方和北领地的叶下珠（Breynia cernua）上发现的。该菌在同一植株上或不同植株上均能形成表皮下的精细胞和Milesia型孢子囊，同时还能形成Milesia型夏孢子囊和典型的层孢类冬孢子囊。在Breynia上没有已知的雌雄同株的大环Phakopsoraspecies。锈孢子和夏孢子顶部厚壁，具数个分散的芽孔。除了普通的夏孢子和冬孢子外，该真菌在夏孢子中形成单细胞、深色、厚壁、侧向游离的孢子。这种真菌的特征是顶端厚壁的夏孢子，产生于Milesia型夏孢子菌中，具有几个分散的芽孔，并在夏孢子菌中定期产生单细胞的游离冬孢子样孢子。因此，建议将其作为一个新种，P.breyacarpus。
APhakopsorafungus was found onBreynia cernua(Phyllanthaceae) in northern Queensland and Northern Territory, Australia. The fungus formed subcuticular spermogonia andMilesia-type aecia together withMilesia-type uredinia and typical phakopsoroid telia on the same or separate plants. No autoecious, macrocyclicPhakopsoraspecies was previously known onBreynia. Aeciospores and urediniospores were apically thick-walled and bore several scattered germ pores. In addition to ordinary urediniospores and teliospores, the fungus formed one-celled, dark-colored, thick-walled, laterally free spores in the uredinia. Apically thick-walled urediniospores, produced in theMilesia-type uredinia, with several scattered germ pores and the regular production of one-celled, free teliospore-like spores in the uredinia characterize this fungus. Thus, it is proposed as a new species,P. breyniae.
