在一条小溪附近的腐烂木材上，发现了一种微小的球状、带毛的鞭毛状担子，与一种气生真菌的分生孢子共存。来源于担子瘤的一个分离物通过将培养物浸泡在水中而产生小球担子菌的分生孢子。另外三个菌株来源于P. glomerulata的分生孢子，在培养约4个月后，在琼脂培养基上产生具有担子样结构的未成熟担子瘤。菌丝隔膜的微细结构为长孔菌型。系统发育分析的基础上从D1/D2区域的LSU rDNA序列表明，从分生孢子和从一个担子瘤聚集在一起的鞭毛菌分支和NIA分支内的膜菌嵌套的菌株。培养研究和分子系统发育分析表明，小球拟青霉属于鞭毛虫型真型（Flagelloscypha teleomorph）。分子生物学数据还表明，小球拟单胞菌与海洋担子菌Nia和Halocyphina有亲缘关系。因此，这项研究表明，cyberyloid担子菌已经演变成海洋以及淡水栖息地的形态适应的有性型在前者和无性型在后者的情况下。
On decayed wood near a stream, tiny cyphelloid, hair-bearing, Flagelloscypha-like basidiomata were found coexisting with conidia of an aero-aquatic fungus, Peyronelina glomerulata. An isolate originating from the basidioma produced conidia of P. glomerulata by soaking the culture in water. Three additional strains originating from conidia of P. glomerulata produced immature basidiomata with basidium-like structures on the agar medium after about 4 months incubation. Fine structure of the hyphal septa of P. glomerulata was found to be of the dolipore type. Phylogenetic analysis based on sequences from the D1/D2 regions of the LSU rDNA showed that the strains from conidia and from a basidioma clustered together in the Flagelloscypha clade and nested within the Nia clade of Hymenomycetes. The culture studies and molecular phylogenetic analysis suggested that P. glomerulata has a Flagelloscypha teleomorph, a cyphelloid basidiomycete. The molecular data also indicate that P. glomerulata is phylogenetically related to the marine basidiomycetes, Nia and Halocyphina. Thus, this study revealed that cyphelloid basidiomycetes have evolved into both marine as well as freshwater habitats by morphological adaptations of the teleomorphs in the former and of the anamorph in the latter case.
