Three pyrenomycetes collected from woody debris submerged in freshwater habitats are described as new species of Luttrellia: L. guttulata sp. nov., L. halonata sp. nov. and L. parvulospora sp. nov. A collection of L. estuarina, the type species of the genus, having ascospores surrounded by a gelatinous sheath, a characteristic not observed in the type specimen, is reported. The genus description is emended to include fungi with 4- or 8-spored asci and ascospores with or without a gelatinous sheath. Luttrellia is distinguished from other genera in the Halosphaeriaceae by hyaline, phragmoseptate, and thick-walled ascospores with or without a gelatinous sheath.
