Abstract

Arthopyrenia sensu lato comprises lichenicolous, lichenized and non-lichenized saprotrophic species; however, the lifestyle of several taxa as either lichenized or saprotrophic remains unclear. The systematic position of the genus was so far unresolved: while sequenced species appeared in different clades within Dothideomycetes, the type species, A. cerasi, had no molecular data so far. In lieu of sequence data, the family Arthopyreniaceae was assigned to Pleosporales, whereas tropical, lichenized species were reclassified in Constrictolumina and Macroconstrictolumina, shown to belong in Trypetheliaceae (Trypetheliales). In this study, the generic type, A. cerasi, has been sequenced for the first time. Maximum likelihood and Bayesian phylogenetic analyses using mtSSU and nuLSU sequences recovered Arthopyrenia sensu stricto as an early diverging lineage within Trypetheliaceae, separate from Constrictolumina and Macroconstrictolumina but in the same clade as the temperate, non-lichenized Julella fallaciosa. Therefore, Arthopyreniaceae is here synonymized under Trypetheliaceae and the taxonomic placement of its type species is discussed based on morphological and phylogenetic evidence.

模式种的测序结果表明，铁锥虫科是铁锥虫科的同义种

棘皮虫包括地衣、地衣化和非地衣化腐养物种;然而，一些分类群的生活方式是地衣化的还是腐养的尚不清楚。迄今为止，该属的系统位置尚未确定:虽然已测序的物种出现在dothideomycates的不同分支中，但模式种A. cerasi迄今没有分子数据。代替序列数据，将arthropyreniaceae归属于Pleosporales，而将热带地衣化的物种重新划分为缢虫门和大缢虫门，显示其属于trypethelae (Trypetheliales)。在本研究中，首次对属型A. cerasi进行了测序。利用mtSSU和nuLSU序列进行的最大似然和贝叶斯系统发育分析显示，严格意义上的arthropyrenia是trypethelaceae中的一个早期分化谱系，与缢虫门和大缢虫门分开，但与温带、非地衣化的fallacosa属同一进化支。因此，本文将石竹属植物同义归入石竹属植物，并根据形态学和系统发育的证据对其模式种的分类定位进行了讨论。我们的系统发育结果进一步支持Mycosphere 12(1): 993-1011 (2021) www.mycosphere.org ISSN 2077 7019
