Sticta属的四种被描述为玻利维亚的新物种,基于真菌ITS条形码标记的形态学检查和系统发育分析。此外,据报道,玻利维亚有两个物种是新物种(分子数据证实了它们的鉴定),而先前报道的一个物种首次被分子数据证实。提供了所有新物种的详细形态学和解剖学描述。两个新物种,S.isidiolobulataOssowska,B.Moncada,Lücking&KukwaandS.madidiensisOssowska,B.Moncada,Lücking&Kukwa属于我的进化枝,正如以前的研究中所定义的那样。相比之下,S.montepunkuensisOssowska,B.Moncada,Lücking&KukwaandS.macrolobataOssowska,B.Moncada,Lücking&Kukwa,这里也描述为新的科学,属于CladeIII.Stictaisidiolobulata具有中等大小的不规则至近圆形thall,isidia发育成蝶形小叶,蓝细菌光生体和白喉,具有整个至弱圆齿的边缘。与蓝藻相关的S.macrolobata的大型不规则thallus具有宽阔的裂片,有疣状到被绒毛的边缘和有凸起边缘的囊状突起,而马迪尼有一个中等大小的,掌状到不规则的带柄的thallus,但没有营养繁殖体和食草。Stictamontepunkuensis具有大而不规则的thalli,绿藻作为光生物,具具圆齿到疣状边缘和具宽孔和粗糙基底膜的瓶形囊环。两个物种,S.beauvoisiiDelise和S.ripariaMerc。-据报道,Díaz是玻利维亚的新成员(后者也是南美的新成员),属于第三进化枝。Stictatomentosa(Sw。)Ach。,通过分子数据从玻利维亚确认的物种,属于CladeII.Stictabeauvoisii的特点是光滑的黄棕色上表面,有较深的顶点和丰富的,边缘isidia和棕色的下表面,带有金巧克力棕色的初级绒毛和稀疏,金棕色根茎。Stictriparia有一个强烈分支的thallus,有起伏的裂片和丰富的,边缘,掌状,灰色到深棕色的叶状和灰棕色的下表面,朝向边缘没有初级绒毛。Stictatomentosa有掌状,带白色纤毛和丰富的蓝色thalli,边缘下脱泡和乳白色的下表面,稀疏,白色初生绒毛。
Four species of the genus Sticta are described as new from Bolivia, based on morphological examination and phylogenetic analysis of the fungal ITS barcoding marker. Additionally, two species are reported as new to Bolivia (their identification confirmed by molecular data) and one previously reported species is confirmed by molecular data for the first time. Detailed morphological and anatomical descriptions are provided for all new species. Two of the new species, S.isidiolobulata Ossowska, B. Moncada, Lücking & Kukwa and S.madidiensis Ossowska, B. Moncada, Lücking & Kukwa belong to clade I, as defined in previous studies. In contrast, S.montepunkuensis Ossowska, B. Moncada, Lücking & Kukwa and S.macrolobata Ossowska, B. Moncada, Lücking & Kukwa, also described here as new to science, belong to clade III. Stictaisidiolobulata has an irregular to suborbicular thallus of medium size, with isidia developing into spathulate lobules, cyanobacterial photobiont and apothecia with entire to weakly-crenate margins. The large irregular thallus of the cyanobacteria-associated S.macrolobata has broad lobes, apothecia with verrucous to tomentose margins and cyphellae with raised margins, whereas S.madidiensis has a medium-sized, palmate to irregular thallus with a stipe, but without vegetative propagules and apothecia. Stictamontepunkuensis has large and irregular thalli with green algae as photobiont, apothecia with crenate to verrucous margins and urceolate cyphellae with a wide pore and a scabrid basal membrane. Two species, S.beauvoisii Delise and S.riparia Merc.-Díaz are reported as new to Bolivia (the latter also as new to South America) and belong to clade III. Stictatomentosa (Sw.) Ach., species confirmed from Bolivia by molecular data, belongs to clade II. Stictabeauvoisii is characterised by a smooth yellowish-brown upper surface with darker apices and abundant, marginal isidia and a brown lower surface with golden-chocolate brown primary tomentum and sparse, golden-brown rhizines. Stictariparia has a strongly branched thallus, with undulate lobes and abundant, marginal, palmate, grey to dark brown phyllidia and greyish-brown lower surface with the primary tomentum absent towards the margins. Stictatomentosa has palmate, bluish thalli with white cilia and abundant, submarginal apothecia and creamy-white lower surface with a sparse, white primary tomentum.
