Sulfur Tuft

Hypholoma fasciculare

Group
gilled mushroom
Spore print
Purple-brown
Size
Cap diameter 2-6 cm; stipe 5-10 cm long and 0.3-1 cm thick.
Season
Typically found from spring through late autumn, or even early winter in milder climates.
Habitat
Grows in dense clusters on decaying wood of both broadleaf and coniferous trees.
Distribution
Widely distributed across Europe and North America; one of the most common woodland fungi.
Key characteristics
Convex to flattened cap with a sulfur-yellow to orange-brown center, greenish-yellow gills that darken to purple-brown with age, and a slender, crowded growth habit.
Fruiting body
Cap is 2-6 cm wide, smooth, yellowish with a darker center. Gills are crowded, initially sulfur-yellow then becoming olive-green and finally brownish. Stipe is 5-10 cm long, sulfur-yellow, often curved, and lacks a permanent ring but may have a faint veil zone.
How to recognise it
Look for the characteristic sulfur-yellow color and the diagnostic greenish tint in the gills. It almost always grows in tight clusters (tufts) on wood.
Look-alikes
Hypholoma capnoides (lacks green gill tint), Hypholoma lateritium (brick-red cap), Armillaria species (white spore print, distinct ring).
Ecological role
Saprophytic; it plays an important role in breaking down dead wood in forest ecosystems.
Notes
This fungus contains several bioactive compounds including fasciculols. It is highly resistant to many fungal diseases and is sometimes studied for its ability to compete with wood-rotting pathogens like honey mushrooms.
