“…S. bina S. Hughes) differ mainly in branching of conidiophores and catenation of conidia. Diplococcium spicatum produces catenate conidia on branched conidiophores, whereas Spadicoides bina produces solitary conidia on unbranched conidiophores (Hughes 1958;Ellis 1963;Sinclair et al 1985;Goh and Hyde 1996). The conidiophore branching was considered to be taxonomically more important at the generic level than conidial catenation by earlier mycologists (e.g.…”

“…Ellis 1963Ellis , 1971aEllis , b, 1972Wang 1976;Wang and Sutton 1982). Sinclair et al (1985), however, stated that at the generic level, conidiophore branching is taxonomically less important than conidial catenation, and emended the generic description of Spadicoides to include species that produce solitary conidia from conidiophores that may be simple or branched. This generic delineation based on a single anamorphic character has been accepted by several authors (e.g.…”

Partial 28S rRNA gene sequence-data of the strains of the anamorphic genera Bahusutrabeeja, Diplococcium, Natarajania, Paliphora, Polyschema, Rattania and Spadicoides were analysed to predict their phylogenetic relationships and taxonomic placement within the Ascomycota. Results indicate that Diplococcium and morphologically similar genera, i.e. Spadicoides, Paliphora and Polyschema do not share a recent common ancestor. The type species of Diplococcium, D. spicatum is referred to Helotiales (Leotiomycetes). The placement of Spadicoides bina, the type of the genus, is unresolved but it is shown to be closely associated with Porosphaerella species, which are sister taxa to Coniochaetales (Sordariomycetes). Three Polyschema species analysed in this study represent a monophyletic lineage and are related to Lentithecium fluviatile and Leptosphaeria calvescens in Pleosporales (Dothideomycetes). DNA sequence analysis also suggests that Paliphora intermedia is a member of Chaetosphaeriaceae (Sordariomycetes). The type species of Bahusutrabeeja, B. dwaya, is phylogenetically related to Neodeightonia (=Botryosphaeria) subglobosa in Botryosphaeriales (Dothideomycetes). Monotypic genera Natarajania and Rattania are phylogenetically related to members of Diaporthales and Chaetosphaeriales, respectively. Future studies with extended gene datasets and type strains are required to resolve many novel but morphologically unexplainable phylogenetic scenarios revealed from this study. It is increasingly becoming evident that a fungal lineage may include a mosaic of anamorphs, teleomorphs and pleomorphs whose morphologies may not always be correlated. It is therefore suggested that where possible all new species descriptions, whether teleomorphic, anamorphic or pleomorphic, should include DNA sequence-data to facilitate amalgamation of anamorphic and pleomorphic genera in a single phylogenetic classification system.

“…A separação entre os dois gêneros é feita com base na catenação dos conídios. Spadicoides possui coní-dios solitários, enquanto Diplococcium apresenta conídios catenados (Sinclair et al 1985, Goh & Hyde 1996. Análises moleculares sugerem que algumas espécies de Spadicoides estão filogeneticamente relacionadas com as classes Dothideomycetes e Sordariomycetes (Shenoy et al 2010), revelando a natureza polifilética do gênero.…”

RESUMOoleracea were collected and kept in a moist chamber for seven days. Somatic and reproductive fungal structures were extracted from the substrate and mounted on semi-permanent slides for morphological study using optical microscopy. This paper includes descriptions, comments, geographical distributions and illustrations of new records for Brazil. All these records are new for the study area, 11 are new records for Brazil, and 12 are new for the Brazilian Amazon.

“…For separating these two genera, Wang and Sutton (1982) used the unbranched conidiophores as an important character of Spadicoides. Sinclair et al (1985), however, adopted the catenation of conidia to separate these genera, and they removed four Spadicoides species, including S. stoveri, to Diplococcium. Twenty-one species were accepted in the review of Diplococcium by Goh and Hyde (1998).…”
