Examination of genera of the Pseudoascoboleae (Ascomycetes, Discomycetes, Ascobolaceae) revealed that many were polytypic. Characters presently used to distinguish these genera are considered to be artificial and true relationships cut across accepted generic lines. Of the genera treated, Thecotheus and parts of Ascophanus, since their asci blue in iodine and their spores bear callose‐pectic markings, are considered more closely related to the Pezizeae. Other genera are excluded from the Pseudoascoboleae because of other striking characters. Since the Pseudoascoboleae is shown to be an artificial grouping, it is proposed to abandon the name, using instead the tribe name Theleboleae, placed in the Pezizaceae rather than the Ascobolaceae, for all of those genera with asci that do not blue in iodine, with smooth, elliptical spores without oil guttules, and with eight‐spored and multispored species. Four new genera are described: Iodophanus, for species of Ascophanus with iodine‐positive asci; Coprotus, for segments of Ascophanus and Ryparobius; Caccobius, for species intermediate to Ascozonus and Thelebolus; and Trichobolus, for the setose members of Thelebolus. The species of Ryparobius not belonging to Coprotus are transferred to Thelebolus.

The nomenclatural status and history of the generic name Isaria are reviewed. Authorship and typification are discussed, and we conclude that Isaria Pers. : Fr. is a validly published generic name that has previously been effectively and appropriately lectotypified by Isaria farinosa (Holm : Fr.) Fr. A lectotype illustration and an epitype specimen are designated for I. farinosa. We suggest that the name Isaria be used for species previously assigned to Paecilomyces section Isarioidea Samson. Further taxonomic studies are required to determine the appropriate circumscription of Isaria. Our conclusions preserve a Friesian genus in a familiar sense.

SummaryIn current classifications of the Suboperculate Discomycetes, a single family, Sarcoscyphaceae, is almost universally recognized, with two tribes, Sarcoscypheae and Umuleae. An older family name is available, and the correct name for the family as currently delimited must be Sarcosomataceae, and of the tribes, Sarcoscypheae and Sarcosomateae respectively. A new classification is proposed here, in which two families are delimited, each divided into two tribes: Sarcosomataceae (= Urnuleae sensu Le Gal), with tribes Sarcosomateae and Galielleae, and Sarcoscyphaceae emend. (= Sarcoscypheae sensu Le Gal) with tribes Sarcoscypheae and Boedijnopezizeae. Twenty-five genera are assigned positions under the families and tribes recognized in the new classification. The family name Sarcoscyphaceae, even with its emended circumscription, is technically a superfluous name, but arguments are advanced for retaining the name in its new concept and for non-application of Article 63 of the Code of Nomenclature.This paper concerns itself with the suprageneric nomenclature of the order Pezizales, suborder Sarcoscyphineae as delimited by Rifai (1968), and attempts to provide correct names for the family and tribes almost universally recognized in the group, as well as for those families and tribes proposed here in a new taxonomic arrangement. These fungi are often referred to as the Suboperculate Discomycetes following the pioneering research by Le Gal (1946). In nearly all recent treatments a single family is recognized, Sarcoscyphaceae, divided into two tribes, Sarcoscypheae for bright-colored species, Urnuleae for those with brown-black pigments (Le
