Marasmiellus ramealis, also known as Twig Parachute, is a very small, delicate agaric with a whitish to pale cream cap, widely spaced pale gills and a slender stem that becomes brown towards the base. It grows on dead twigs and small branches of both deciduous and coniferous trees, as well as on dead bramble stems. It can occur on fallen material or on dead twigs that are still attached to living trees. Fruiting bodies typically appear from summer to late autumn.

Cap white to pale cream, initially convex and becoming flatter with age. The surface is smooth to finely textured, while the margin often develops conspicuous radial wrinkles or grooves as the cap expands. Gills pinkish-white when young, becoming ochre or yellowish-brown with age. They are narrow, widely spaced and adnate, attaching directly to the stem. Stem slender and delicate, whitish or pale cream near the apex and gradually becoming darker brown towards the base. Its surface may appear slightly scurfy or finely roughened. There is no ring. Flesh is very thin and pale, with no distinctive smell or taste.

Habitat saprotrophic on dead woody material, particularly small twigs and branches of deciduous broadleaf trees and conifers. It is also frequently found on dead bramble stems. Because it often fruits on attached dead twigs, specimens may sometimes occur well above ground level.

Spore print white.

Microscopic features spores cylindrical to bean-shaped, smooth, 7.5–11 × 2.5–4 µm and inamyloid.
