Phylogenetic analyses showed no difference between these two collections of  C. thailandicum( MFLU13-0632 and MFLU10-0008). The ITSand LSUsequence data are 99% identical. However, there are some differences in the respect of morphology.  C. thailandicum( MFLU13-0632) was found on dead leaves and has 5-septate ascospores lacking a sheath, while the typewas found on living leaves, with 7–9-septate ascospores, with a mucilaginous sheath.
