Two fungal isolates were isolated from diseased leaves of Philodendron selloum in Guangxi medicinal garden,Nanning,Guangxi. It indicated that they should belong to Lasiodiplodia based on morphological observation,and they were very similar to Lasiodiplodia theobromae after further comparison in morphology.Meanwhile,the multi-gene phylogenetic tree based on the DNA sequences of ITS,β-tubulin and elogation factor( EF-α) of isolates collected in this study and the ex-type strain of L. theobromae was built up. The results also supported that these two fungi were L. theobromae. The test of Koch's rule confirmed that L. theobromae was the pathogen of this disease. This is the first report about L. theobromae causing P. selloum disease in China.
