Hypholoma fasciculare
species of fungus
Hypholoma fasciculare, commonly known as the sulphur tuft or clustered woodlover, is a common woodland mushroom, often in evidence when hardly any other mushrooms are to be found. This saprotrophic small gill fungus grows prolifically in large clumps on stumps, dead roots or rotting trunks of broadleaved trees.
The "sulphur tuft" is bitter and poisonous; consuming it can cause vomiting, diarrhea and convulsions.
Taxonomy
The specific epithet is derived from the Latin fascicularis 'in bundles' or 'clustered', referring to its habit of growing in clumps. Its name in Japanese is Nigakuritake (苦栗茸, means "Bitter kuritake").
Description
The hemispherical cap ranges from 2–8 cm (3⁄4–3+1⁄8 in) in diameter. It is smooth and sulphur yellow with an orange-brown centre and whitish margin. The crowded gills are initially yellow but darken to a distinctive green colour as the blackish spores develop on the yellow flesh. It has a purple-brown spore print. The stipe is 3–12 cm (1+1⁄8–4+3⁄4 in) tall and 3–10 mm wide, light yellow, orange-brown below, often with an indistinct ring zone coloured dark by the spores.
The public source identifies “Hypholoma fasciculare” as species of fungus. This brief keeps that definition visible, then builds a research path around Hypholoma, fasciculare and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Hypholoma fasciculare”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q752507. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
