Gilled mushrooms

Sulphur tuft

Hypholoma fasciculare · also known as: Clustered woodlover

Poisonous

Poisonous – causes gastrointestinal poisoning; First Nature mentions severe cases and at least one probable death. The very bitter taste usually prevents poisoning, but in a mix with other mushrooms the bitterness may go unnoticed. Confusing it with the honey fungus is a classic mistake.

Is the sulphur tuft edible?

Poisonous. Poisonous – causes gastrointestinal poisoning; First Nature mentions severe cases and at least one probable death. The very bitter taste usually prevents poisoning, but in a mix with other mushrooms the bitterness may go unnoticed. Confusing it with the honey fungus is a classic mistake.

When does the sulphur tuft grow?

In Poland the fruiting bodies usually appear in: April, May, June, July, August, September, October, November, December. Habitat: Very common; in masses, in clusters on rotting stumps and trunks of broadleaf trees, less often conifers, also on buried wood (then it “grows from the ground”).

What can the sulphur tuft be mistaken for?

Honey fungus (edible with care): The honey fungus has a white spore print, whitish/beige gills (never greenish) and a membranous ring; the cap is honey-brown with dark scales. Sheathed woodtuft (edible): The sheathed woodtuft has a membranous ring, a warm brown cap, rusty-brown gills and spore print, and a mild taste. Note: the edible conifer tuft (Hypholoma capnoides; grey gills, mild taste, grows on conifers) is also similar – only for the experienced.
