In Phomopsis leptostromiformis two varieties, leptostromiformis and occidentalis have been known. The present investigation confirmed that only P. l. var. occidentalis produced its teleomorph in vitro. For this fungus, isolated in Western Australia, the name Diaporthe woodii is recognized. Observations of the fungal development on infected lupin stubble in the field resulted in the discovery of the teleomorph of the Phomopsis state earlier recognized as var. leptostromiformis, which causes the lupinosis problem in grazing animals. The teleomorphs of the two taxa are sufficiently different to regard them as two distinct species. A new species, D. toxica, is described for the teleomorph of the toxigenic Phomopsis.
