| Three plant-inhabiting fungi with tetraradiate conidia, Tricornispora bambusae Bonar, Fumagopsis triglifioides Speg., and Eriosporella calami (Niessl) Höhn., the type species of monotypic genera, are redescribed and illustrated from type specimens. These genera are regarded as distinct. Fumagopsis is possibly closely related to Kazulia Nag Raj. Since the type specimen of Tridentaria Preuss did not bear a fungus which agreed with the very brief original description, the genus Tridentaria Preuss is regarded as doubtful. The nematode-trapping Hyphomycetes formerly placed in Tridentaria should be reclassified. |

| A number of pycnidial fungi described from Atriplex and Chenopodium, in Europe, North- and South-America are brought into synonymy with Phoma variospora nom. nov., Phoma dimorphospora (Speg.) comb. nov. and Ascochyta caulina (P. Karst.) comb. nov. Descriptions of these species in vivo and in vitro are given and the differentiating characters are discussed. A. caulina represents the type species of Chaetodiplodia P. Karst., which genus is reduced to the level of a section of Ascochyta Lib. |

| Thirty taxa in Phoma sect. Phyllostictoides, characterised by secondary septation of a variable number of conidia, are described in vitro. Two Phyllostictoides-like species are (re)classified in sect. Sclerophomella on account of certain pycnidial characteristics. Short notes on the ecology and distribution are added. Newly proposed taxa are: Phoma acetosellae (A. L. Sm. & Ramsb.) Aa & Boerema comb, nov., Phoma argillacea (Bres.) Aa & Boerema comb. nov. (teleomorph Didymella applanata (Niessl) Sacc.), Phoma nepeticola (Melnik) Dorenb. & de Gruyter comb, nov. (teleomorph Didymella catariae (Cooke & Ellis) Sacc.), Phoma destructiva var. diversispora de Gruyter & Boerema var. nov., Phoma heliopsidis (H.C. Greene) Aa & Boerema comb,... |

| A description is given of the morphological characters of Phoma section Phyllostictoides and its taxonomical position is discussed. A key is provided for the varieties of the type species Phoma exigua Desm., followed by a host-fungus and a fungus-host index. Two new varieties are proposed: Phoma exigua var. forsythiae (Sacc.) comb. nov. and Phoma exigua var. noackiana (Allesch.) comb. nov. The synonymy, selected literature, a representative culture and data on ecology and distribution are given for all varieties. |

| Van der Aa & van Kesteren (1979) redescribed a Phoma species commonly occurring on species of Chenopodium in Europe, as Phoma variospora v. d. Aa & v. Kest. After the appearance of this publication, in November 1979, descriptions of some new species of Phoma came to their attention amongst which was also Phoma variospora Shreemali (1978, issued in July 1979) based on a different fungus. According to the rules of priority Phoma variospora v. d. Aa & v. Kest. has to be renamed. The following name change is proposed: Phoma heteromorphospora v. d. Aa & v. Kest., nom. nov. Phyllosticta chenopodii Westend. in Bull. Acad. r. Belg. Cl. Sci. 11. 2: 567. 1857. Phoma variospora v. d. Aa & v. Kest. in Persoonia 10: 268. 1979. — non Phoma variospora... |

| Asordaria gen. nov. is introduced for Sordariaceae with ovate or broadly ellipsoidal, smooth ascospores without gelatinous sheath. The genus is based on Asordaria tenerifae spec. nov. Seven species of Sordaria are reclassified in Asordaria and a further species is described as A. islandica. Asordaria is considered to be more closely related to Boothiella, Neurospora, Gelasinospora, and Melanocarpus than to Sordaria, which is restricted to species with elongate ascospores with a gelatinous sheath. Melanocarpus oblatus spec. nov. is described. |

| Four monotypic genera have been described for Deuteromycetes with superficial, crustose or pulvinate, setose conidiomata and hyaline, septate stauroconidia consisting of a main axis and 2—3 apical branches. The types of Fumagopsis Spegazzini (1910), Vonarxia Batista & Bezerra (1960) and Kazulia Nag Raj (1977) are specimens collected in South America. All develop superficially on living or decaying leaves. Phalangispora constricta Nawawi & Webster (1982) has been described from a pure culture isolated from conidia collected at Malaya. Fumagopsis trigliphioides Speg. has been redescribed by Van der Aa & Van Oorschot (1985) from the type specimen collected in 1909 in Argentina on leaves of Lucuma neriifolia. It forms a pigmented, setose,... |
