Fig. 1 Letendraea eurotioides (NY0091436, lectotype, modified from Fig. 9 in Ariyawansa et al. 2014). a Semi-immersed to superficial, globose-subglobose ascomata. b–d Asci. e–g Ascospores. Scale bars: b = 50 μm, c–g = 10 μm.
Importance and distribution
Industrial relevance and applications
Letendraea is useful in medical and pharmaceutical industry as it produces polyketides that are used in antibiotics (Xu et al. 2020). Letendraea helminthicola parasitizes the hyphomycete Helminthosporium velutinum and might be an effective biocontrol agent (Krug et al. 2004).
Biochemical importance of the genus, chemical diversity or applications
Letendraea produces wide range of chemicals. Huang et al. (2019) reported letenketals A and B, two spirocyclic polyketides from a marine crab-derived Letendraea sp. Xu et al. (2020) also reported polyketides production from a marine-derived Letendraea sp. 5XNZ4-2.
There are 18 Letendraea epithets in Index Fungorum (2022), but several species have been transferred to Bellojisia, Calostilbe, Jobellisia, Pseudocosmospora and Xenonectriella. Letendraea comprises 12 species known on wide range of plants such as Cinnamomum sp. (Lauraceae), Cordyline sp. (Asparagaceae), Corylus avellana (Betulaceae), parasitic on Helminthosporium sp. (Massarinaceae), Memora pedunculata (Bignoniaceae), Rubus fruticosus (Rosaceae), Salix fragilis (Salicaceae), Theobroma cacao (Malvaceae) and Viburnum tinus (Adoxaceae). Letendraea is known from Asia (China (Taiwan), India, Thailand), Europe (Poland, Portugal, Sweden, United Kingdom), South America (Brazil) and The United States.
