Geosmithia属的所有次crealean种都是与树皮甲虫有联系的变形真菌。本文描述了在中欧与carpini、S. intricatus和S. rugulosus有亲缘关系的新同域种——fassatiae、G. langdonii和G. obscura。该物种是由三个姊妹类群组成的复合体，它们与黄芪具有亲缘关系，可以通过形态学差异、独特的RAPD模式和ITS区rDNA序列来区分。描述和讨论了新种的种内变异性和生境特异性。在形态、遗传和生态方面的高度一致性表明，这些地铁匠属是最近产生的。提供了所有已被接受的该属的下crealean物种的关键。
All hypocrealean species of the genus Geosmithia are anamorphic fungi with connections to bark beetles. G. fassatiae, G. langdonii and G. obscura are described as new sympatric species associated with Scolytus carpini, S. intricatus and S. rugulosus in Central Europe. The species represent a complex of three sister taxa with affinities to G. flava that may be distinguished by differences in morphology, unique RAPD patterns and by sequences of ITS region rDNA. Intraspecific variability and habitat specificity of new species is described and discussed. The high morphological, genetic and ecological uniformity suggest that these Geosmithia spp. are recently derived. A key to all accepted hypocrealean species of the genus is provided.
