Four compounds were isolated from the broth culture of Volvariella bombycina and they were identified as ergosta-4,6,8(14),22-tetraene-3-one (1), ergosterol peroxide (2), indole-3-carboxaldehyde (3) and indazole (4) by interpretation of spectroscopic data. Among them, compound 2 exhibited melanogenesis inhibitory effect in cultured B16 mouse melanoma cells.

The greatest diversity of culturally relevant fungi in Mexico has been recorded in temperate forests. Likewise, it has been proven that people who live in such environments possess greater ethnomycological knowledge, compared with people in the lowlands. In this study, we investigated whether the uses and perceptions of fungi were different between people living near forests in highlands and those living in lowlands near grasslands and subtropical scrublands.

Since mushrooms have many bioactive components, they have been used as components in folk medicine. Because mycelium has an advantage when it comes to large-scale production, this study aimed to evaluate the antioxidant properties and anti-tyrosinase activity from 55 mycelia in culture media. Relatively high 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity was detected from the ethanol extract of culture media including mycelium (EECiM) of Morchella esculenta var.
