, large-sized: > 600 μm S63845 price diam. Question mark (“?”) before family (or genus) name means its familial (or generic) status within Pleosporales (or some particular family) is uncertain. Other question marks after habitats, latin names or other substantives mean the correctness of their usages need verification. Results Molecular phylogeny In total, 278 pleosporalean taxa are included in the phylogenetic analysis. These form 25 familial clades in the dendrogram, i.e. Aigialaceae,

Amniculicolaceae, Arthopyreniaceae, Cucurbitariaceae/Didymosphaeriaceae, Delitschiaceae, Didymellaceae, Dothidotthiaceae, Hypsostromataceae, Lentitheciaceae, Leptosphaeriaceae, Lindgomycetaceae, Lophiostomataceae, Massariaceae, Massarinaceae, Melanommataceae, Montagnulaceae, Morosphaeriaceae, Phaeosphaeriaceae,

Pleomassariaceae, Pleosporaceae, Sporormiaceae, Testudinaceae/Platystomaceae, Tetraplosphaeriaceae, Trematosphaeriaceae and Zopfiaceae (Plate 1). Of these, Lentitheciaceae, Massarinaceae, Montagnulaceae, Morosphaeriaceae and Trematosphaeriaceae form a robust clade in the present study and in previous studies (Schoch et al. 2009; Zhang et al. 2009a, b). We thus emended the suborder, Massarineae, to accommodate them. Pleosporales suborder Massarineae Barr, Mycologia 71: 948. (1979a). emend. Habitat freshwater, marine or terrestrial environment, saprobic. Ascomata solitary, scattered or gregarious, globose, subglobose, conical to lenticular, immersed, erumpent to superficial, papillate, ostiolate.

Hamathecium of dense or rarely few, filliform pseudoparaphyses. AMN-107 mouse Asci bitunicate, fissitunicate, cylindrical, clavate or broadly clavate, pedicellate. Ascospores hyaline, pale brown or brown, 1 to 3 or more transverse septa, rarely muriform, narrowly fusoid, fusoid, broadly fusoid, symmetrical or asymmetrical, with or without sheath.
