Is Sulphur tuft Toxic?

Sulphur tuft possesses a notably bitter taste and is associated with severe poisonings. Its toxins, referred to as 'Fasciculol', a potentially toxic triterpenoid organic compound, are not extensively studied. Nevertheless, ingestion should be avoided due to potential toxicity. This species is saprobic and is often found in clusters on broad-leaf trees and, less commonly, conifers. While opinions vary on its precise toxicity, the extreme bitterness acts as a natural deterrent, reinforcing the advisory against consumption.
