Notes.

Collection MFLU 15-1169 was identified as Dictyocheirospora indica ( Dictyosporium indicum ) based on morphological examination. Phylogenetic analyses indicated the placement of this taxon within Dictyocheirospora and sister to Di. subramanianii (BCC 3503). Dictyocheirospora subramanianii differs from Di. indica in lacking appendages. Dictyocheirospora indica resembles Di. musae in having non-complanate, cylindrical conidia with globose to subglobose appendages. However, conidial appendages of Di. indica are attached at the subapical cells, while appendages of Di. musae are attached at the central cells of the outer cell-row. The conidial size of Di. indica (33-48 × 13-18 µm) is smaller than that of Di. musae (45-65 × 20-27 µm) ( Photita et al. 2002, Prasher and Verma 2015). In this study, sequence data of our collection Dictyocheirospora indica (MFLUCC 15-0056) was generated and, as there is no sequence data available for the previous collection ( Dictyosporium indicum ), we therefore designated our collection as the reference specimen (sensu Ariyawansa et al. 2014) for Dictyocheirospora indica .
