A dense tuft of Brook-side Feathermoss (Hygroamblystegium fluviatile) fills the right side of the image, growing over a dark, damp rock surface. The shoots form a loose but layered mat, branching irregularly and overlapping.
Individual shoots are around 1–1.5 cm long, with leaves approximately 1 mm in length. The leaves are ovate to lance-shaped, concave, and arranged along the stems in a slightly spreading pattern, giving the moss a softly feathery appearance.
The colour ranges from bright green to green-gold, with the tips catching the light and appearing more vivid, while the lower layers sit in shadow. The surface appears moist, and the structure of the mat suggests it is adapted to hold water as it creeps over the rock.
The background falls away into soft blur, hinting at the surrounding streamside habitat.
A sloping limestone rock runs diagonally from lower left to upper right, its surface dark and wet with a thin sheen of water. Across it spreads bright green to green-gold Brook-side Feathermoss (Hygroamblystegium fluviatile), a bryophyte forming a soft, continuous mat.
Several slender reddish setae (spore stalks) rise vertically from the moss near the centre, each approximately 2 cm tall, with small developing capsules at their tips. The shoots creep along the rock surface, branching loosely and overlapping to hold moisture.
To the left, a smaller, tighter patch of the same moss forms a low cushion over another small rock. Among the mat are a few tiny round leaves of Dotted Thyme-moss (Rhizomnium punctatum), adding contrast in form.
Above, a dry brown oak leaf rests on the rock. Behind it, the woodland floor recedes into soft focus: dark soil, leaf litter, and hints of ferns. The scene sits in a damp, shaded streamside habitat where water periodically flows over the rock.
The oak leaf provides scale: individual moss leaves are around 1 mm long, and the shoots approximately 1.5 cm in length.
I think this is Brook-side Feathermoss (Hygroamblystegium fluviatile) growing on limestone rock beside a small stream.
Described by some as drab, to me it glowed green-gold in the afternoon sun.
