Classification: Lulworthiaceae, Lulworthiales, Lulworthiomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood. Sexual morph: Ascomata gregarious, deeply embedded, subhyaline. ellipsoidal-cylindrical, ostiolate, coriaceous, papillate. Peridium two-layered, outer layer of flat melanized cells, inner layer thin-walled, hyaline flattened pseudoparenchyma cells. Paraphyses/catenophyses lacking. Asci 8-spored, cylindrical, short pedunculate, unitunicate, thin-walled, deliquescing early, lacking apical apparatus. Ascospores filiform, hyaline, aseptate, curved or twisted with an apical conoid end chamber filled with mucilage. Asexual morph: Undetermined.
Notes: Rostrupiella was introduced by Koch et al. (2007) from wood collected at Vedbaek harbour, Denmark with typical filiform ascospores with end chambers of Lulworthia species. However, a phylogenetic analysis of 28S rDNA showed it did not group with the type species Lulworthia fucicola (Campbell et al. 2005).
Type species: Rostrupiella danica Jørg. Koch, K.L. Pang & E.B.G. Jones, Bot. Mar. 50(5/6): 295 (2007).
Other accepted species: Species Fungorum – search Rostrupiella.
