摘要

嗜苔藓子囊菌Octopora meslinii是一种很少报道的物种,专门生长在沙苔Grimmia pulvinata的垫子上。该分类单元在过去一直被误解,迄今为止只可靠地从法国和德国报道。最近从匈牙利收集的许多藏品使人们有可能更好地了解O.meslinii,本文对其进行了全面的描述和说明。由于缺乏原始材料,我们在序言中指定了一幅插图作为选择型,并将最近收藏的一幅插图指定为这种真菌的表型。meslinii八孢菌与生长在相同类型栖息地或具有相似子囊孢子的其他八孢菌进行了比较。与墨氏O.meslinii亲缘关系最密切的物种是假ampezzana。与亲苔藓的Pezizales相比,两者都有黑色色素沉着的末端古猿,这是一个独特的特征,椭圆形子囊孢子装饰着孤立的疣,苔藓科中的苔藓宿主,以及根瘤上诱导感染的疣。使用EF1、LSU和SSU rDNA基因座进行的系统发育分析证实了我们的形态学发现,即梅氏O.meslinii与假ampezzana形成一个单系分支,而梅氏O.Mesliii过去与之混淆的其他物种,如相似O.similis,只存在远缘。

Disentangling the taxonomy of Octospora meslinii (Pezizales), a bryophilous ascomycete on Grimmia pulvinata.
The bryophilous ascomycete Octospora meslinii is a rarely reported species growing exclusively in cushions of the saxicolous moss Grimmia pulvinata. The taxon has been misunderstood in the past and hitherto reliably only reported from France and Germany. Many recent collections from Hungary have made it possible to get a better understanding of O. meslinii, which is comprehensively described and illustrated in this paper. Because of the lack of original material, we designate an illustration in the protologue as the lectotype and one of the recent collections as the epitype of this fungus. Octospora meslinii is compared with other species of Octospora growing in the same type of habitat or having similar ascospores. The most closely related species to O. meslinii is O. pseudoampezzana. Both share apothecia with blackish pigmentation, a unique feature compared to bryophilous Pezizales as a whole, ellipsoid ascospores ornamented with isolated warts, moss hosts in the family Grimmiaceae, and the infection inducing galls on the rhizoids. A phylogenetic analysis using the EF1 , LSU and SSU rDNA loci confirms our morphological findings showing that O. meslinii forms a monophyletic clade with O. pseudoampezzana, whereas other species with which O. meslinii was confused in the past, e.g. O. similis, are related only distantly.

期刊介绍: Czech Mycology (former "Česká Mykologie") is an peer-reviewed international scientific journal publishing papers in all aspects of mycology including taxonomy, ecology, physiology and mycofloristics as well as mycological topics in forestry, agriculture and medicine. Czech Mycology publishes full length papers and short communications reporting original research which make a significant contribution to mycology. Review articles are also published.
