Handkea utriformis (HU), H. excipuliformis (HE) and Vascellum pratense (VP) mature fruiting bodies methanol extracts were tested for biological activities and active compounds. The extracts showed prominent radical scavenging, reducing, antioxidative and chelating abilities. Scavenging ability was correlated with phenolic (ABTS assay) or phenolic and/or sugar/β-glucan content (DPPH). Antioxidative and Fe3+-reducing ability of VP extract was the highest, and was best correlated with flavonoid content. The same extract exhibited the best angiotensin-converting enzyme inhibitory activity. HU and HE showed selectivity toward tumor cell lines in cytotoxicity analysis. The extracts exhibited various antimicrobial activity, the best being against Listeria monocytogenes (HE, MIC-0.625 mg/mL); fatty acid content was particularly high in HU (37.25 mg/g), with linoleic acid making up more than 57% in all samples. Phenolics were present in considerable amount, as well as β-glucans (HU, 16.67%). Although these mushrooms are inedible after autolysis process, they were still a good source of biologically active products.
