Luttrellia Shearer, Mycologia 70 (3): 692 (1978) Description. Saprobic on submerged balsa test panels. Sexual morph. Ascomata superficial, globose to subglobose membranous, becoming pale brown ostiolate, neck long, cylindrical hyaline and periphysate. Asci clavate to cylindrical, thin-walled and deliquescing. Catenophyses present. Ascospores hyaline, multiseptate and lacking appendages. The only genus in the Halosphaeriaceae with tetrasporic asci. Asexual morph. Undermined. Type species. Luttrellia estuarina Shearer, Mycologia 70 (3): 693 (1978). Notes. Shearer (1978) assigned Luttrellia to the Halosphaeriaceae as it compared with hyaline, unappendaged ascosporous genera in the family: Lignincola, Nais and Aniptodera, but chose not to emend the generic concept of Nais. Luttrellia species are saprobic on wood in freshwater and brackish water. Molecular evaluation. There are no DNA sequences available for any Luttrellia species. Recollection, isolation and sequencing are required to determine the taxonomic position of the four Luttrellia species in the Halosphaeriaceae.
