Contributions towards a monograph of Phoma (Coelomycetes) – X. Section Pilosa (taxa with a Pleospora teleomorph) and nomenclatural notes on some other taxa

The two anamorphs classified so far in Phoma sect. Pilosa (‘hairy’ pycnidia in vitro) are both metagenetically related to species of the ascomycetous genus Pleospora. In addition to their characteristics in vitro and in vivo short comments on the hosts, literature data, ecology and distribution are given. The notes include additional documentation of the type specimens (dried cultures) of the recently described Phoma schneiderae Boerema et al., Phoma pimpinellae Boerema et al. and Phoma leveillei var. microspora de Gruyter & Boerema. Some excluded species are discussed as new proposed taxa: Asteromella ulmi nom. nov. (teleom. Mycosphaerella ulmi Kleb.), Microsphaeropsis fuckelii (Sacc.) Boerema comb. nov. (teleom. Leptosphaeria coniothyrium (Fuckel) Sacc.) and Microsphaeropsis glumarum (Ellis & Tracy) Boerema comb. nov.
