Stone monuments and relics are prone to biodeterioration processes prompted by microbial proliferation and activity. Among the distinct microbes capable of stone colonization, fungi are known to strongly contribute to stone biodeterioration. During the ongoing efforts aiming to study fungi thriving in dolomitic limestone walls of the Coimbra's hypogean Roman cryptoporticus (Portugal), two unknown isolates were retrieved. The aim of this work was to depict the molecular and phenotypic characteristics of these microorganisms. The phylogenetic analyses revealed that the studied strains could not be assigned to any of the currently known genera. Moreover, the isolates exhibited distinctive and peculiar characteristics, such as the packing of conidia by surrounding hyphal segments and the formation of rope-like microsclerotia with a . Taking into account all the data obtained, a novel genus and species, gen. et sp. nov. in (), is proposed here.
石碑和遗迹容易受到微生物繁殖和活动引发的生物劣化过程影响。在能够在石头上定殖的不同微生物中，已知真菌对石头生物劣化有很大影响。在旨在研究葡萄牙科英布拉地下罗马拱廊式地下室白云质石灰岩墙壁上生长的真菌的持续工作中，分离出了两株未知菌株。这项工作的目的是描述这些微生物的分子和表型特征。系统发育分析表明，所研究的菌株不能归入目前已知的任何属。此外，这些分离株表现出独特而奇特的特征，例如分生孢子被周围的菌丝段包裹以及形成具有……的绳状小菌核。考虑到所获得的所有数据，在此提出一个新属和新种，即（）中的……属及……种。
