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  .
