This paper presents the reinterpretation of the taxonomic position of fossil epiphyllous callimothalloid fungi belonging to the fossil-genera Callimothallus (hitherto classified to the family Microthyriaceae) and Cribrites (?Microthyriales). These fungi thrived from the Late Cretaceous up to the Holocene. Investigation are based on collected material from the Oligocene of Hungary and the Miocene of Poland and on published data. For the common callimothalloid fungus Callimothallus pertusus, a new combination Neomycoleptodiscus pertusus is proposed. Callimothallus quilonensis is assigned to a new fossil-genus Muyocopromyces as a new combination Muyocopromyces quilonensis. We reconsider the fossil-species Ratnagiriathyrites hexagonalis as a younger synonym of the fossil-genus Cribrites. The geographical range of fossil callimothalloid fungi and their recent counterparts are discussed. Fossil Neomycoleptodiscus, Muyocopromyces, and Cribrites are proposed as reliable climate proxy of warm climate conditions in the past.

化石callimothalloid真菌：修订分类法，现代等效物和古生态学

本文重新解释了属于化石属 Callimothallus（迄今归入 Microthyriaceae 科）和 Cribrites (?Microthyriales) 的化石栉栉栉枝菌类真菌的分类位置。这些真菌从晚白垩世一直到全新世蓬勃发展。调查基于从匈牙利渐新世和波兰中新世收集的材料和已发表的数据。针对常见的Callimothalloid真菌Callimothallus pertusus，提出了一种新的组合Neomycoleptodiscus pertusus。Callimothallus quilonensis 作为新组合 Muyocopromyces quilonensis 被归入一个新的化石属 Muyocopromyces。我们重新考虑化石物种 Ratnagiriathyrites 六边形化石作为化石属 Cribrites 的年轻同义词。讨论了化石callimothalloid真菌的地理范围及其最近的对应物。化石 Neomycoleptodiscus、Muyocopromyces 和 Cribrites 被提议作为过去温暖气候条件的可靠气候代表。
