Common Funnel

Description

The common funnel is a medium-sized mushroom with a cap 3–15 cm across, which is convex with a hump when young and very quickly becomes deeply funnel-shaped. The cap is matt, smooth or slightly felted, in shades from cream and beige to tan, and fades with age. The gills are white, later yellowish, crowded and run far down the stem. The stem is slender, flexible, lighter than the cap, with white felt at the base. The flesh smells faintly of almonds or has no smell.

It grows from June to November in deciduous and coniferous woods, on fallen leaves and conifer needles, often in groups, sometimes in rings. It is very common throughout Poland. It avoids acidic and poor soils.

It can be confused with Paralepista flaccida, which usually has brownish spots on the cap and no hump, and with other funnel-shaped species. Among similar small, whitish funnel caps there are poisonous species, so collect only specimens you recognise with certainty. If in doubt, do not pick it and do not eat it.

Identification features

Cap

Diameter 3–15 cm; in young fruiting bodies convex, with an inrolled margin and a hump, quickly becoming concave and funnel-shaped, with a straightened, sometimes wavy and spotted margin. Thin-fleshed, matt, slightly felted to smooth. Colour pale ochre, ochre-cream, beige to tan, sometimes with a pinkish tinge or reddish-brown; fading in older fruiting bodies. No ring or veil remnants.

Hymenophore (underside of the cap)

Gills crowded, running far down the stem, at first white, later yellowish.

Stem

Height 2–10 cm, thickness up to 1 cm, cylindrical, slightly widened towards the base, soft and flexible; cottony inside in young fruiting bodies, hollow in older ones. Surface bare, whitish or pale yellow, with white felt at the base. The stipe is lighter in colour than the cap. No ring; stems can be tough.

Flesh

Creamy white, thin. Smell faintly of almonds, in some descriptions resembling freshly mown hay, or absent; taste mild. The variety adstringens (Central Europe) has an unpleasant taste. Do not taste the flesh.

Spore print and spores

Spore print white. Spores broadly ellipsoid to tear-shaped, with one pointed end, smooth, non-amyloid, white; 5–9 × 3.5–6 µm (descriptions give different ranges).

Habitat and distribution

Ecology. Saprotroph, often growing in groups, sometimes forming fairy rings. Grows on fallen leaves and conifer needles, in leaf litter, also on rotting bark. Avoids acidic and poor soils. Found under various trees, including fir, grey alder, hornbeam, beech, spruce, pine and black locust.

Distribution. Widespread in North America, Europe and Asia (including Japan); in the Southern Hemisphere known only from Australia. Very common in Europe, including Poland, in deciduous and, less often, coniferous woods. It is not legally protected in Poland and is not on the list of mushrooms approved for sale in Poland.

Fruiting. June to November (summer–autumn).

What can it be confused with?

• Infundibulicybe costata (lejkogłówka karbowana) — No detailed data on the differences.
• Paralepista flaccida (gąsówka rudawa) — Usually has brownish spots on the cap and no hump.
• Infundibulicybe catinus — Cap white, sometimes with a pinkish tinge, smell slightly mealy; according to some authors it is merely a colour form of I. gibba.
• Infundibulicybe squamulosa, Pseudoclitocybe cyathiformis, Bonomyces sinopicus, Singerocybe adirondackensis — Species listed as similar; no detailed data on the differences.
• Small whitish funnel caps of the genus Clitocybe (e.g. Clitocybe rivulosa, Clitocybe dealbata) — They are poisonous (they contain muscarine). Usually smaller, whiter or greyish, often growing in grassy clearings and in fairy rings; do not collect funnel caps without certain identification.

Never rely on a single feature. If you are not sure — do not pick it; show the mushroom to a qualified mushroom expert.

Interesting facts

• The epithet gibba comes from Latin gibbus ("humped") and refers to the hump on the cap of young fruiting bodies; the common English name is common funnel.
• The species was described by Christiaan Hendrik Persoon in 1801 as Agaricus gibbus; since 2003 it has been the type species of the genus Infundibulicybe, created by Harri Harmaja.
• The name of the old synonym infundibuliformis comes from Latin infundibulum – "funnel".
• The Polish name lejkogłówka żółtobrązowa was recommended in 2025 by the Commission for Polish Fungal Nomenclature of the Polish Mycological Society.
