Importance and distribution

Acrospermum is useful for pharmaceutical and food industry as there is evidence of unique polysaccharide containing mannofuranose from the cell wall of A. compressum (Prieto et al. 2007). There are 42 Acrospermum epithets in Index Fungorum (2022), but several species have been transferred to Ascocoryne, Cyanodermella, Glyphium, Holwaya, Hypocreopsis and Typhula. Acrospermum comprises 27 species known on Adenostyles alpina (Asteraceae), Aegopodium podagraria (Apiaceae), Agropyron sp. (Poaceae), Agrostis perennans (Poaceae), Alnus rugosa (Betulaceae), Aruncus dioicus (Rosaceae), Betula nigra (Betulaceae), Boehmeria cylindrica (Urticaceae), Brachypodium sylvaticum (Poaceae), Bromus sp. (Poaceae), Broussonetia papyrifera (Moraceae), Calamagrostis canadensis (Poaceae) amongst others. Acrospermum is reported from Asia (China, Pakistan, Russia), Europe (Austria, Denmark, Germany, Netherlands, Poland, Portugal, Sweden, United Kingdom) and North America (Canada, The United States).
