Weeping Widow

The Weeping Widow is the best-known member of Lacrymaria, a small genus in the family Psathyrellaceae that sits close to the brittlestems (Psathyrella) and the inkcaps. It was long treated as Psathyrella velutina, and older field guides still list it under that name; molecular work separated Lacrymaria on the strength of its roughened, warted spores and its distinctly hairy fruit body.

What sets it apart from its mostly fragile relatives is substance. Where a typical Psathyrella is thin, pallid and almost translucent, the Weeping Widow is a solid, tawny, densely felted mushroom that holds its shape for days. The genus name comes from lacrima, a tear: in damp air the gill edges exude small clear beads that darken as spores are shed onto them, giving the mottled gill face a spotted, weeping appearance.

It is one of the commonest larger fungi of mown grass, path edges and made ground across the temperate Northern Hemisphere, and is often the only substantial dark-spored mushroom fruiting on a suburban verge in autumn.

Cap

The cap is 3-10 cm across, at first conical or bell-shaped and later broadly convex to nearly flat with a low broad umbo. The colour is warm tawny to date-brown or ochre-brown, fading paler as it dries. The whole surface is covered in fine matted hairs and radiating fibrils that can break into small scales towards the centre. The margin is characteristically hung with pale toothlike remnants of the veil, at least when young.

Gills

Gills are crowded and adnate to slightly notched at the stipe. They begin pale greyish-buff, then become clouded and mottled purplish-brown to almost black as the spores ripen unevenly. The gill edges stay whitish and finely fringed, and in humid conditions they carry rows of small watery droplets that stain dark where spores settle - the feature the common name refers to.

Stipe

The stipe is 4-10 cm tall and 0.5-1.5 cm thick, roughly equal or slightly thickened at the base, whitish above and browner below, and covered with the same woolly fibrils as the cap. There is no true membranous ring, but a fibrillose ring zone is usually visible in the upper third, dyed almost black by falling spores.

Flesh & spore print

The flesh is pale brown, soft but not as fragile as in most brittlestems, and does not change colour appreciably when cut. The spore print is very dark brown to blackish. Under a microscope the spores are lemon-shaped and conspicuously warted, an unusual feature in this group and the main technical character of the genus.

The Weeping Widow is a mushroom of open, disturbed and heavily trodden ground rather than deep woodland. Typical sites include lawns, playing fields, roadside verges, gravelly path edges, woodchip beds, allotment margins and the compacted soil beside tracks. It frequently appears in tight clusters or arcs, sometimes in troops of dozens, and often returns to exactly the same patch of ground year after year.

Fruiting runs from late spring through to the first hard frosts, with the main flush in late summer and autumn after rain. The species is widespread across Europe and temperate Asia, occurs throughout much of North America, and has been recorded in Australasia and southern Africa, very often in urban and horticultural settings where soil has been moved or amended.

This is a saprotrophic fungus, drawing its nutrition from dead organic matter rather than from a living plant partner. Its mycelium works through buried wood fragments, old root systems, woodchip mulch and grass thatch, breaking down cellulose and lignin residues in the upper soil layers. The strong preference for compacted and enriched ground reflects the abundance of buried woody debris in such places.

Because it colonises made ground so readily, it is one of the pioneer decomposers that follows landscaping, path building and mulching. The dense clustered fruiting habit comes from a single large mycelial patch throwing up many caps from one buried mass of woody debris, and the near-black spores are released over several days as the gills mature unevenly from the edge inward.

Psathyrella candolleana shares grassy and path-side habitats but has a smooth, hygrophanous cap that dries from honey-brown to nearly white, a brittle hollow white stipe with no woolly covering, and gill edges that never bead with droplets. Agrocybe praecox also fruits on woodchip and grass, but its cap is smooth and buff, it carries a distinct membranous ring, and its spore print is a plain dull brown rather than blackish.

Panaeolus species growing in the same lawns have smooth, often hygrophanous caps with no shaggy fibrils, slender fragile stipes, and strongly mottled gills with a jet-black print. Lacrymaria pyrotricha is the closest relative likely to confuse: it is a brighter orange to rusty-tawny mushroom of woodland and burnt ground, with more vividly coloured hairs and a slimmer build.
