项目摘要

Many fossil fugimorphs were recovered from permineralized fossils from the Paleozoic of Queensland, Australia, and the Mesozoic of Hokkaido, Japan. Within calsified nodules from Hokkaido containing both plant and fungal remains, three new species of inperfect fungi, Archephoma cycadeoidellae, Menisicoideisporites cretacea, Palaeodiplodites yezoensis, each belonging to new genus, have been described in International Journal of Plant Research. Some other rather poorly preserved fungimorphs need further investigation. These results largely contribute to the study of fossil fungi that lacks cumulative evidence on the Mesozoic fungi.In the Permian permineralized peat from Australia were found remains of possible Oomycetes, Ascomycetes, and unidentifiable fungiform in either in plant tissues or in peat matrix. Because of unexpectedly poor preservatory condition of the material, details should be more carefully examined.Most of the Hokkaido fungi were probably saprophytic. However, some species of the extant genus Phoma, which can be closely compared to the fossil Archephoma, are pathogenic. Such pathogenic species have originated from saprophytic species in post-Cretaceous vegetation in which Angiosperms continued to diversify. Present progress in molecular phylogeny of fungi may strengthen the importance of fossil evidence as was revealed in this study for better understanding of fungal phylogeny.Lack of sufficient fossil information prevented from deeply discussing the ecological correlations with fungi and plants.

在澳大利亚昆士兰州古生代和日本北海道中生代的过矿化化石中发现了许多化石。在北海道的钙化结核中发现了三个新的不完全真菌种，分别为Archephoma cycadeoidae、Menisicoideisporites cretacea和Palaeodiplodites yezoensis，它们都属于新的属。其他一些保存较差的真菌形态需要进一步研究。这些结果在很大程度上有助于真菌化石的研究，缺乏累积证据的中生代fungies.In二叠纪permineralized泥炭从澳大利亚被发现的可能的卵菌，子囊菌，和unidentifiable fungiform在植物组织或泥炭基质的遗骸。由于材料的干燥条件出乎意料地差，细节应该更仔细地检查。大多数北海道真菌可能是腐殖酸的。然而，现存的茎点霉属的一些物种，可以与化石Archephoma密切比较，是致病的。这些致病物种起源于后白垩纪植被中的腐殖物种，其中被子植物继续多样化。目前真菌分子系统学研究的进展可能会加强化石证据的重要性，因为缺乏足够的化石信息阻碍了深入讨论真菌和植物的生态关系。
