Notes – The monotypic genus Bacusphaeria is similar to Tirisporella, because they have large, thick-walled ascomata, cylindrical asci and both occur on the basal petioles of Nypa fruticans in brackish water. However, Bacusphaeria is distinct from Tirisporella because it; i) lacks complex ascospore appendages; ii) has fewer septa in the ascospores (Bacusphaeria: 1–5-septate vs. Tirisporella: 5–7-septate); iii) lack of paraphyses; iv) has a prominent apical ring in contrast to faint apical ring in Tirisporella; v) having generally uniseriate ascospores in contrast to biseriate ascospores in Tirisporella. Base pair differences of Bacusphaeria nypae (MFLU 13-0617) and Tirisporella beccariana (BCC38300) are 97 bp different out of 859 bp (11.29%) without gaps in the LSU gene locus. Furthermore, in phylogeny, Bacusphaeria nypae is distinct from the other two genera and formed a separate lineage in Tirisporellaceae
Type species: Bacusphaeria nypae Norlail., Alias & Suetrong, in Abdel-Wahab et al., Bot. Mar. 60(4): 479 (2017).
Other accepted species: Species Fungorum – search Bacusphaeria.
