标题罗丽亚属一新种及罗丽亚属的有性变型。水生植物的描述，与插图，从腐烂的淹没在尼罗河，埃及木材。部分SSU和LSU rDNA序列数据的分子系统发育分析将L. aquatica和新种L.在一个单系分支中的网孢菌属，与淡水林丝菌科中的密切相关的真菌相距甚远。LSU rDNA序列比对结果表明，有性/无性变异的L.水生植物有99%相似Lolia种的特征是假囊或座层，浸入到erumicum，深棕色到黑色，革质到近碳质的子囊，圆柱状棍棒状，重石状，裂状，短花梗子囊，黄色到红棕色，Phragmo-或网孢子，被突出的凝胶状鞘包围。Lolia物种在遗传学上与密切相关的属：Leptosphaeria（Leptosphaeriaceae）和Massariosphaeria（Pleosporales incert. sed.）。Lolia与Leptosphaeria的不同之处在于有一个明显的大的凝胶状子囊孢子鞘，而Leptosphaeria种没有。Lolia与Massariosphaeria的不同之处在于具有较小的子囊孢子和较少的横隔膜。根据分子生物学数据和形态学特征，建立了一个新种--网孢绿百合Lolia dictyospora。
A new species of Lolia and the sexual morph of L. aquatica are described, with illustrations, from decayed submerged wood in the River Nile, Egypt. Molecular phylogenetic analyses of partial SSU and LSU rDNA sequence data place the sexual morph of L. aquatica and the new species, L. dictyospora in a monophyletic clade, distant from the closely related fungi in the freshwater family Lindgomycetaceae. Pairwise LSU rDNA sequence alignment of the sexual/asexual morphs of L. aquatica are 99% similar. Lolia species are characterized by pseudothecial or stromatic, immersed to erumpent, dark-brown to black, coriaceous to sub-carbonaceous ascomata, cylindric-clavate, bitunicate, fissitunicate, short pedicellate asci, yellow to reddish-brown, phragmo- or dictyospores, surrounded by prominent gelatinous sheath. Lolia species are phylogenetically distant from the closely related genera: Leptosphaeria (Leptosphaeriaceae) and Massariosphaeria (Pleosporales incert. sed.). Lolia differs from Leptosphaeria in having a prominent large gelatinous ascospore sheath, while this is absent in Leptosphaeria species. Lolia differs from Massariosphaeria in having smaller ascospores and fewer transverse septa. Based on molecular data and morphology, a new species, Lolia dictyospora, is established.
