The morphology and nomenclature of ca. 195 families of bitunicate or alleged bitunicate ascomycetes are discussed. Available representatives of these families were studied especially with respect to the morphology of the asci and ascospores. The morphology of the ascomata, etc. was studied in the SEM in 73 species. The following morphological terms are introduced: hamathecium, pseudoprototunicate, pseudofis–situnicate, semifissitunicate, and umbilicus. The following taxa are described as new: Coccodiniaceae O. Erikss. fam. nov., Microtheliopsidaceae O. Erikss. fam. nov., Amarenomyces O. Erikss. gen. nov., and Euantennaria abietina O. Erikss. sp. nov. The name Lecanidiaceae is proposed to replace Patellariaceae Corda, and Cyanoder–mella to replace Cyanoderma Höhn. The Massariaceae are treated as Trypetheliaceae subfam. Massarioideae (Nits.) O. Erikss. The following new combinations are proposed: Amarenomyces ammophilae (Lasch) O. Erikss., Cyanodermella viridula (Berk. & Curt.) O. Erikss., C. Candida (Setch.) O. Erikss., Dictyotrichiella delicatula (Ves–tergr.) O. Erikss., Laurera sepulta (Mont.) O. Erikss., Splanchnonema superans (Mull. Arg.) O. Erikss. and Thelenella antarctica (M. Lamb) O. Erikss. The origin and evolution of the Ascomycetes are discussed, and the importance of paedomor–phosis in the transspeciation of the group is emphasized. The stratigraphic classification of the Ascomycetes is discussed. In a transitional classification of the Ascomycetes, 109 monophyletic entities (clades) are recognized. La morphologie et la nomenclature ?environ 195 families ?ascomycétes bituniques ou soit–disant bituniques sont étudiées, spécialement en respectant la morphologie des asques et des ascospores. La morphologie des ascocarpes, etc. de 73 espèces fut étudiée dans le SEM. Les termes morphologiques suivants sont introduits: hamathecium, pseudoprototunique, pseudofissitunique, semifissitunique et umbilicus. Ces nouveaux taxa sont decrits: Coccodiniaceae O.
