Overview
The Fan-shaped Jelly Fungus (Dacryopinax spathularia) is a vivid, cosmopolitan wood-decay basidiomycete belonging to the jelly fungus family Dacrymycetaceae. Instantly recognizable by its miniature, brilliant orange to golden-yellow spatulate or paddle-shaped fruiting bodies, this resilient organism erupts in dense, cheerful colonies along cracks in damp, decaying hardwood logs. Renowned across tropical and subtropical forestry for its remarkable poikilohydric abilities, it can desiccate into an inconspicuous crust during dry spells and rapidly reconstitute into vibrant gelatinous paddles upon the return of rainfall.
Biology and Physical Characteristics
Dacryopinax spathularia produces small, gregarious basidiocarps measuring 10 to 25 mm tall that emerge from a subterranean mycelium anchored deep within woody substrates. Each fruiting body consists of a cylindrical, tough fibrous stipe that broadens upward into a flattened, fan-shaped or spoon-like petal. The texture is cartilaginous-gelatinous, richly saturated with lipid-soluble carotenoid pigments that generate its signature bright tangerine to saffron-orange hue. Microscopically, it bears fork-shaped (tuning fork-type) basidia characteristic of the order Dacrymycetales, each producing two elongated, curved basidiospores that develop cross-walls (septa) prior to germination.
Behavior and Ecology
Functioning as an essential saprotrophic decomposer within forest ecosystems, Dacryopinax spathularia breaks down structural cellulose and hemicellulose in dead wood, contributing to brown wood rot and releasing locked nutrients back into woodland humus. It is commonly found on barkless logs, weathered wooden railings, structural fence posts, and forest branches exposed to intense sunlight and periodic drying. During drought, its basidiocarps shrivel into dark, hard, resinous flakes; within minutes of rainfall, the tissues absorb water, swelling back into plump, fertile spore-producing paddles.
Conservation and Human Impact
Dacryopinax spathularia is evaluated as secure and globally common. It faces no conservation threats, thriving across disturbed rural landscapes, secondary forests, and managed timber lots throughout the tropics and warm-temperate regions. In traditional Chinese medicine and rural culinary traditions across southern China and Southeast Asia, it is gathered under names such as ‘sweet osmanthus ear’ (guihua’er) and prized as a traditional vegetarian delicacy added to festive noodle dishes and soups.
Interesting Factoid
The Fan-shaped Jelly Fungus is a tiny orange mushroom that can literally come back to life: when baked by the blazing sun it dries up into a hard dark flake, but as soon as a raindrop hits it, it absorbs the water and puffs back up like brand new orange gummy candy!
