Description
Summary:Submersisphaeria palmae sp. nov. is described and illustrated from petioles, rachides and trunks of palms at Sirindhorn Peat Swamp Forest, Narathiwat, in southern Thailand. This species has much smaller ascospores than most previously described species. A key to the five accepted species is given and S. palmae is compared with the most similar taxa. Helicoubisia coronata was collected from the palm, Eleiodoxa conferta, also in the Peat Swamp Forest. Helicoubisia is characterised by erect conidiophores bearing discrete, polyblastic conidiogenous cells at the apex and coiled, pale brown conidia. Helicoubisia and Moorella are discussed and M. monocephala is relegated to synonymy of H. coronata.
