NOTES: Currently nine Anthostomella species have been recorded from marine habitats with three (N. nypensis, N. nypicola, N. nypae) known from the brackish water palm Nypa fruticans (Hyde et al. 1999. Loilong et al. 2012), while others are known from mangrove wood, Spartina spp., Phragmites communis or Juncus roemerianus (Namiar & Raveendran 2011). The marine Anthostomella species are in need of further collecting so that they can be sequenced.
