Dothideomycetes families incertae sedis » Dothideomycetes genera incertae sedis


Lucidascocarpa A. Ferrer, Raja & Shearer

Index Fungorum number: IF 508169


Saprobic on submerged wood. Sexual morph: Ascomata scattered to clustered, immersed or superficial, uniloculate, globose to subglobose, white, membranous, with long, cylindrical, white necks, periphysate. Peridium composed of several layers of elongate, thin-walled, hyaline cells of textura angularis. Pseudoparaphyses absent. Asci 8-spored, bitunicate, fissitunicate, clavate, pedicellate, with gelatinous material around the apex of the endoascus. Ascospores overlapping biseriate, ellipsoidal to fusiform, hyaline, septate, verruculose, thin-walled, surrounded by a large gelatinous sheath (Ferrer et al. 2008). Asexual morph: Undetermined. (Description from Dong et al. 2020)


Type species: Lucidascocarpa pulchella A. Ferrer, Raja & Shearer


Notes: The monotypic genus Lucidascocarpa, typified by L. pulchella, is unusual in Dothideomycetes. It has white ascomata with long neck, gelatinous material around the apex of the endoascus, and phragmoseptate, rough-walled ascospores surrounded by a large gelatinous sheath (Ferrer et al. 2008). The light coloured ascomata and well-developed sheath of Lucidascocarpa are similar to Aliquandostipite (Jahnulales) (Inderbitzin et al. 2001), but no pseudoparaphyses and wide, brown, septate hyphae in Lucidascocarpa. Lucidascocarpa was suggested in Dothideales based on fissitunicate asci without pseudoparaphyses, but it cannot be assigned to any existing families (Ferrer et al. 2008). It is now placed in Dothideomycetes genera incertae sedis (Wijayawardene et al. 2018, 2020). Distributional studies of freshwater ascomycetes indicated that L. pulchella might be restricted to the neotropics (Ferrer et al. 2008; Shearer et al. 2015). Sequence data of L. pulchella are needed. (Notes from Dong et al. 2020)
