Cryptic diversity found in Didymellaceae from Australian native legumes

Ascochyta koolunga (Didymellaceae, Pleosporales) was first described in 2009 (as Phoma ) and identified as the causal agent of blight Pisum sativum (field pea) South Australia. Since then A. has not been reported anywhere else world, its origins occurrence on other legume (Fabaceae) species remains unknown. Blight leaf spot diseases Australian native, pasture naturalised legumes were studied to investigate a possible native origin . detected or that had symptoms, any regions southern Australia, only one isolate recovered from P. However, we isolated five novel Didymellaceae spots commercial field pea throughout The classified basis morphology phylogenetic analyses internal transcribed spacer region part RNA polymerase II subunit B gene region. Three these species, Nothophoma garlbiwalawarda sp. nov. , naiawu ngayawang Senna artemisioides here are Epicoccum djirangnandiri Swainsona galegifolia Neodidymelliopsis tinkyukuku Hardenbergia violacea In addition, report three new host-pathogen associations namely Didymella pinodes S.
