采用分子系统发育方法,利用ITS、nuSSU、nuLSU、TEF1-α和RPB2 5个标记,对曲曲菌小叶生成员的潜在隐种形成进行了研究。(曲菌科),包括最近分离的Phylloporis属、Puiggariella属、Raciborskiella属、Racoplaca属和Serusiauxiella属,来自亚洲热带地区,并以新热带地区的精选资料为参考。在分子与表型相结合的基础上,获得了Racoplaca属2个新种和Strigula s.str属10个新种。分别为:大孢子虫、斑纹虫、广东刺虫、中间刺虫、叶刺虫、微刺虫、假刺虫、假枯草刺虫、假枯草刺虫、绿刺刺虫、中国混凝土刺虫、窄刺刺虫和枯草刺虫。此外,本文还提出了新组合Phylloporis palmae comb。11 .(≡=Manaustrum palmae),我们验证了之前的组合Racoplaca melanobapha comb。11月(≡黑瘤疣;黑瘤条)。我们的数据清楚地表明,在小叶生的曲条藻代表中有相当程度的隐多样性。特别是在可能广泛分布的分类群中,如抗尖藻、混凝土藻、nitidula和smaragdula。鉴于这些系统发育修正迄今为止仅限于少数地区,我们预测我们的发现只代表了众所周知的这组地衣真菌的冰山一角。
We employed a molecular phylogenetic approach using five markers (ITS, nuSSU, nuLSU, TEF1-α, and RPB2) to assess potential cryptic speciation in foliicolous members of Strigula s.lat. (Strigulaceae), including the recently segregated genera Phylloporis, Puiggariella, Raciborskiella, Racoplaca, and Serusiauxiella, from tropical areas in Asia, with selected materials from the Neotropics as reference. On the basis of combined molecular and phenotypic datasets, two new species of Racoplaca and 10 new species of Strigula s.str. are described: Racoplaca macrospora sp. nov., R. maculatoides sp. nov., Strigula guangdongensis sp. nov., S. intermedia sp. nov., S. laevis sp. nov., S. microcarpa sp. nov., S. pseudoantillarum sp. nov., S. pseudosubtilissima sp. nov., S. pycnoradians sp. nov., S. sinoconcreta sp. nov., S. stenoloba sp. nov., and S. subtilissimoides sp. nov. In addition, we propose the new combination Phylloporis palmae comb. nov. (≡ =Manaustrum palmae) and we validate the earlier combination Racoplaca melanobapha comb. nov. (≡ Verrucaria melanobapha; Strigula melanobapha). Our data clearly indicate a considerable degree of cryptic diversification in foliicolous representatives of Strigula s.lat., particularly in the presumably widespread taxa Strigula antillarum, S. concreta, S. nitidula, and S. smaragdula. Given that these phylogenetic revisions are thus far limited to few regions, we predict that our findings only represent the proverbial tip of the iceberg in this group of lichenized fungi.
