Molecular phylogeny and morphology reveal two new graminicolous species, and . with new records of spp from Sri Lanka.

Despite being a small island, Sri Lanka is rich in fungal diversity. Most of the fungi from Sri Lanka have been identified as pathogens of vegetables, fruits, and plantation crops to date. The pleosporalean genus () includes phytopathogenic, saprobic, endophytic, and human/animal opportunistic pathogenic fungal species.

Synthesis of -Fused Polycyclic Indole Derivatives via Ru(II)-Catalyzed C-H Bond Activation and Intramolecular Hydroarylation.

A new synthesis of -fused tetracyclic indole derivatives and their related polycyclic analogues has been developed based on ruthenium(II)-catalyzed C-H activation and intramolecular hydroarylation. A series of polycyclic indoles with a 3-formyl group have been prepared in good to high yields. Various aliphatic and aromatic amines have been studied to form a transient directing group with the aldehyde for the catalytic process.

Fungi as environmental bioindicators.

Environmental bioindicators are species or communities of animals, plants, bacteria, fungi, algae, lichens, and planktons whose existence, quantity, and nature can be used to make inferences on the quality of the environment. Bioindicators can be used to detect environmental contaminants by on-site visual inspections or through laboratory analysis. Fungi are one of the most important groups of environmental bioindicators due to their ubiquitous distribution, diverse ecological roles, remarkable biological diversity, and high sensitivity to environmental changes.

Molecular reassessment of diaporthalean fungi associated with strawberry, including the leaf blight fungus, Paraphomopsis obscurans gen. et comb. nov. (Melanconiellaceae).

Phytopathogenic fungi in the order Diaporthales (Sordariomycetes) cause diseases on numerous economically important crops worldwide. In this study, we reassessed the diaporthalean species associated with prominent diseases of strawberry, namely leaf blight, leaf blotch, root rot and petiole blight, based on molecular data and morphological characters using fresh and herbarium collections. Combined analyses of four nuclear loci, 28S ribosomal DNA/large subunit rDNA (LSU), ribosomal internal transcribed spacers 1 and 2 with 5.
