Resinicolous fungi have evolved across different fungal lineages, but they are best known within the classes Eurotiomycetes, Leotiomycetes, Orbiliomycetes, and Xylonomycetes. Within the class Dothideomycetes, a resinicolous lifestyle is uncommon and is predominantly known in members of the order Mytilinidiales. In this study, 13 strains of a dark, slow-growing fungus belonging to Dothideomycetes were isolated from resins of four conifer species-, Larixdeciduassp.polonica, , and (all from the family Pinaceae)-in Poland. Based on multi-locus (LSU, ITS, , , ) phylogenetic analyses and morphological features, the isolated strains were identified as representing an undescribed species in a new genus within the order Mycosphaerellales, family Teratosphaeriaceae. Consequently, a new genus and species, , is described and illustrated. It is phylogenetically related to the genera and . The common occurrence of on resins of four different conifer species indicates its resinicolous lifestyle. is the first resinicolous fungus reported in Mycosphaerellales.
树脂生真菌在不同的真菌谱系中都有进化，但在散囊菌纲、锤舌菌纲、圆盘菌纲和炭角菌纲中最为人所知。在座囊菌纲中，树脂生的生活方式并不常见，主要见于小穴壳菌目的成员中。在本研究中，从波兰的四种针叶树——欧洲落叶松、欧洲云杉、欧洲赤松和欧洲黑松（均属于松科）的树脂中分离出13株属于座囊菌纲的深色、生长缓慢的真菌菌株。基于多位点（LSU、ITS、tef1、tub2、rpb2）系统发育分析和形态特征，这些分离菌株被鉴定为代表球腔菌目球腔菌科一个新属中的一个未描述物种。因此，描述并说明了一个新属和新物种，即新球腔菌属波兰新球腔菌。它在系统发育上与球腔菌属和叶点霉属相关。波兰新球腔菌在四种不同针叶树的树脂上普遍存在，表明其树脂生的生活方式。它是球腔菌目中首次报道的树脂生真菌。
