The scientific profile
From the latest record: 2026-07-25.
Plasmodium phase
Watery, translucent to whitish, sometimes faintly yellowish or pinkish
Fruiting bodies
Dense colonies of erect, simple to repeatedly branched, finger- or coral-shaped columns; gelatinous and translucent at first, later white, cream or pale yellow
Peridium
The spores are produced openly on the outer surface rather than enclosed within a sporangium
Attachment
Macroscopic columns sessile on a confluent, mucilaginous hypothallus; each individual spore supported by a delicate microscopic pedicel
Description
Spore mass white to pale yellow
Ecology
On moist, heavily decayed logs, stumps, branches and other plant debris, often appearing in extensive clustered sheets after rain; late spring to autumn
Description
Amoeboflagellate cells → multinucleate plasmodium → coral-like sporophores bearing external stalked spores → spores germinate to release amoeboid or flagellated cells
Edibility
Tiny, gelatinous slime mould with no culinary value
Fruit body
Individual columns approximately 1–10 mm tall and ~0.2–1 mm wide; colonies may spread across many centimetres of decaying wood
Microscopy
Spores smooth, thin-walled, hyaline to very pale yellow, globose, ovoid or ellipsoid, approximately 6–8 × 10–13 µm; borne individually on slender pedicels about 7–20 µm long; true capillitium absent
Overview
Common coral slime forming delicate white, frost-covered miniature antlers or icicles on wet rotten wood
