taxonomic status

Paranectriella and Puttemansia are morphologically similar hyperparasitic fungi reported to be associated with Titaea or Titaea-like anamorphs (Rossman, Myc Papers 157, 1987). Both genera were placed in Paranectriellaceae by Hyde et al. (Families of Dothideomycetes, Fungal Diversity 63: 1-313, 2013). Rossman (Myc Papers 157, 1987) distinguished these two genera by Paranectriella having superficial ascomata and Puttemansia having ascomata erumpent from a stroma within the host substrate. Hyde et al. emphasised numbers of locules in the ascomata and ascospore shape to distinguish the genera. The NZ material has only immature ascomata - these are superficial, so matches Paranectriella sensu Rossman. Paranectriellaceae was placed incertae sedis in Dothideomycetes by Hyde et al. (2013), LSU sequences from PDD 112249 place it sister to Myriangiales and Hysteriales, see notes under PDD 112249 [PRJ, Jan 2019]
