Comments:
This is a monotypic genus assigned tentatively to the Niessliaceae, Hypocreales based on phylogenetic analyses of the SSU and LSU rRNA genes (Pang et al. 2010). However, the familial placement was not fully resolved. The inner wall layer of the necks of S. taiwanensis extends into the upper part of the centrum, an anatomical feature that appears to be previously unknown in the Hypocreales. A similar structure has been observed in Rostrupiella danica, a Lulworthia-like marine fungus (Koch et al. 2007). It is one of the marine species with more than eight ascospores per ascus. Sediciniella taiwanensis was collected on twigs of Kandelia obovate at Chunan Taiwan and a further collection on unidentified mangrove wood at the Furtian Nature Reserve, Shenzhen, China.
