Velvet Shank Identification Guide

A Winter Find

Most gilled fungi have finished by the time this one starts. You come across it on a still, grey day between late autumn and early spring, often with frost on the ground and almost nothing else fruiting. The find is usually made at eye level or above rather than underfoot: a dense cluster of glossy tawny caps erupting from a wound on a standing dead trunk, from the cut face of a stump, or from a fallen branch tangled in a hedge. Elm, ash, willow, poplar and beech are the usual hosts.

The first impression is of colour and shine. Against a bare winter wood the caps look almost varnished, ranging from pale amber at the rim to a deep tawny orange-brown at the centre, and in damp weather they are visibly tacky. The second impression is architectural: the stalks are curved, tangled, and fused into a common base, so the cluster fans outward from a single point on the wood like a bunch of small parasols in a tight grip.

Reading the Cap

Caps run roughly two to eight centimetres across. Young ones are convex, sometimes almost hemispherical, and they flatten with age, often keeping a broad low central rise. The margin starts incurved and expands, and in old, water-soaked specimens it can become slightly wavy or upturned.

The surface is the key. It is smooth, without scales, fibrils or granules, and it is distinctly viscid when wet — press a finger onto a fresh cap and it will cling briefly and lift a faintly sticky film. Dry weather can leave the cap merely shiny and greasy-looking rather than genuinely slimy, but it never becomes matt and felted. Colour is strongest at the disc and fades outward, and thin-fleshed marginal areas can appear paler and translucent when saturated. Peeling the cuticle is easy; it strips off in an elastic sheet.

The Gills

Underneath, the gills are white to pale yellowish-cream, sometimes flushing a light tan with age, and they are moderately spaced rather than crowded. Attachment is adnexed to narrowly adnate — they meet the stalk at a shallow notch and do not run down it. The gill edges are even and pale. Crucially, gills stay pale into maturity; they never darken to a rusty, cocoa or purple tone as the spores mature, because the spores themselves are colourless in deposit.

Examine the gill-stalk junction for veil remnants. There should be none. This species has no partial veil, so there is no ring on the stalk and no cortina fragments hanging from the cap margin at any stage.

The Stalk: Where the Name Lives

Hold a cluster up and look at the stalks from base to apex. They are slender, tough and pliant — you can bend them almost double without snapping, and they resist tearing in a way most agaric stalks do not. The interior becomes hollow with age.

Colour is graded. The top of the stalk, just beneath the gills, is pale yellowish or cream. Moving downwards it darkens progressively through tan and reddish-brown to a deep chocolate or nearly black at the base. Over that dark lower portion lies a short, dense, velvety pile, easily seen with a hand lens and often visible to the naked eye as a matt, suede-like finish that contrasts with the shiny cap above. In young clusters the dark velvet may be restricted to the extreme base; in mature clusters it climbs well up the stalk. Fruit bodies are typically fused at the point of attachment, and pulling one free usually brings a wad of pale mycelium and wood fibre with it.

Flesh, Cut Surfaces and Cold Tolerance

Cut a cap in half. The flesh is thin, whitish to pale yellowish, soft in the cap and tough and fibrous in the stalk. There is no colour change on cutting or bruising, no latex, and no strong odour.

One behavioural character is worth recording in a field notebook because it supports the identification: fruit bodies of this species tolerate freezing. A cluster can be frozen solid, thaw, and resume growth and spore release, which is why you will find intact, well-formed specimens in mid-winter when everything around them has collapsed.

Taking and Reading a Spore Print

Because the caps are small and thin, use two or three of them and give the print time. Detach the caps, lay them gills down on a piece of dark paper or on black card with a white strip alongside, cover with a bowl, and leave for six to twelve hours somewhere cool but not freezing.

The deposit is white. Read it on the dark half of the paper, where a pale print shows clearly, then check for any yellow or brown tinge on the white half. This step is not optional — it is the single most decisive test available, because the most important structural analogues of this species all have coloured deposits.

Substrate, Season and Ecology

This is a saprotroph and weak parasite of broadleaved trees. It colonises heartwood and damaged sapwood through wounds, pruning cuts and frost cracks, and it fruits from that wood in tight tufts. Elm is a classic host, but ash, willow, poplar, beech, oak and various fruit trees all support it. Look on standing dead trunks, on the sawn faces of stumps, along fallen limbs, and out of bark wounds on otherwise living trees.

The fruiting window is essentially the cold season — late autumn, through winter, and into early spring, with flushes triggered by mild damp spells between frosts. It rarely fruits from conifer wood, and finding a supposed specimen on pine or spruce should prompt a careful re-check.

Separating It From Look-alikes

Galerina marginata. Structurally similar in habit, growing in tufts on wood with a brownish cap, but every important character differs: it has a membranous ring or a clear ring zone on the stalk, its gills become rusty-brown as spores mature, and its spore print is a distinct rust-brown. Its stalk is fibrillose and pale-streaked rather than clothed in blackish velvet, and it is far more often on conifer wood.

Kuehneromyces mutabilis. Tufted on broadleaf stumps and superficially close in colour, but it has a ring on the stalk, a scaly or scurfy stalk surface below that ring, a two-toned hygrophanous cap that dries out from the centre in a pale disc with a darker moist margin, and a brown spore print. It also fruits mainly in the warmer half of the year.

Hypholoma fasciculare. Also densely tufted on wood, but its cap is dry rather than viscid, its colour is a sulphur yellow with an olive or greenish tinge in the gills, its gills darken to purple-brown, and its spore print is purple-brown. The stalk lacks the black velvet finish.

Pholiota species. Usually scaly-capped, often viscid, but with a veil and a brown spore print, and with gills darkening accordingly.

Xeromphalina and Tubaria species. Smaller, differently proportioned, and either brown-spored or with decurrent gills; neither shows the graded pale-to-black velvet stalk.

Field Checklist

Cold season; dense tufts on dead broadleaf wood; smooth viscid tawny to amber cap; pale, moderately spaced, adnexed gills that stay pale; no ring anywhere; tough pliant hollow stalk shading from cream at the top to blackish velvet at the base; white spore print. All seven together, and especially the last two in combination, make the identification firm.
