One hundred and five generic types of Pleosporales are described and illustrated. A brief introduction and detailed history with short notes on morphology, molecular phylogeny as well as a general conclusion of each genus are provided. For those genera where the type or a representative specimen is unavailable, a brief note is given. Altogether 174 genera of Pleosporales are treated. Phaeotrichaceae as well as Kriegeriella, Zeuctomorpha and Muroia are excluded from Pleosporales. Based on the multigene phylogenetic analysis, the suborder Massarineae is emended to accommodate five families, viz. Lentitheciaceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae and Trematosphaeriaceae. Keywords Generic type . Massarineae . Molecular phylogeny . Morphology . Pleosporales . Taxonomy. Also lichenicolous taxon studied in detail, i.e. Lichenopyrenis galligena (on Leptochidium ciliata) and lichenized groups are discussed (e.g. Arthopyrenia, Arthopyreniaceae).
