Sulphur tuft

Hypholoma fasciculare

A species of Hypholoma.

The sulfur tuft, a highly effective decomposer of hardwoods, thrives on decaying timber from various tree species. Its fruiting bodies emerge from spring through autumn, often in such dense clusters that their growth is mutually impeded. Ingesting this toxic fungus can lead to transient paralysis, blurred vision, and abdominal discomfort.

Is Sulphur tuft Toxic?

The mushroom known as sulphur tuft is characterized by a very bitter flavor and has been linked to serious cases of poisoning. Its harmful substances, termed 'Fasciculol' – a triterpenoid organic compound with suspected toxicity – have not been thoroughly researched. Despite the limited study, consumption is strongly discouraged due to its potential to cause harm. This particular fungus is saprophytic, commonly growing in groups on deciduous trees and, less frequently, on coniferous ones. Although there's no complete consensus on its exact level of toxicity, its intense bitterness serves as a natural warning, further emphasizing the recommendation to avoid eating it.
