Cuinín Geal (KWIN-een GYAL)

Witches’ Butter / Tremella mesenterica

It appears like a breath caught on bark—soft, golden, and trembling in the filtered light. The Cuinín Geal does not grow in clusters or rings, but as singular, jellylike folds that seem placed rather than sprouted. Its color—pale gold to butter-yellow—catches the eye gently, never jarring, as if it were made to be noticed only when the mind is already still. In Tir na nÓg, it is not a sign of magic gone wrong, but of *feeling released with grace.*   Found on fallen branches or dying wood, the Cuinín Geal does not feed in haste. Its jelly structure pulses faintly in the damp, drawing in moisture and mood alike. Though it reacts to the physical environment, its appearance is most often associated with emotional closure. Many believe it surfaces after moments of deep, quiet catharsis—where grief was spoken aloud to no one, or where joy departed softly, leaving no ache. It is not called forth, but felt into being.   Those who live near its favored groves speak of it as a “listener’s bloom.” Not because it hears in any literal sense, but because it coincides with spaces where things have been *said*—secrets released into moss, regrets exhaled to stones, or gratitude offered without witness. In such moments, when the emotional current is allowed to flow freely without binding to the self, the Cuinín Geal may appear by morning.   Its texture is cool, tremulous, and slightly translucent—like dew solidified into shape. It never hardens. If touched, it does not collapse, but neither does it resist. It is held together by the same subtle stillness that called it forth. Despite its soft appearance, it is long-lasting, able to endure weeks of rainfall and cycles of warming sun without withering. Eventually, it folds back into the branch, fading without rot or residue.   In traditional practice, no offerings are left for Cuinín Geal. To do so is seen as misunderstanding its purpose. Instead, one sits nearby and simply breathes—acknowledging whatever truth the land has acknowledged with its bloom. Some stone circles bear engraved images of its folds, signifying places of reflection and unburdening. It is not sacred because it is rare, but because it never appears without meaning.

Basic Information

Ecology and Habitats

Cuinín Geal is most often found on moist, decaying hardwood—particularly fallen limbs in shaded, undisturbed woodland. It thrives in areas with high atmospheric moisture and low temperature fluctuation, typically emerging after light rainfall or in regions where fog is common. Unlike more aggressive saprobes, Cuinín Geal contributes minimally to structural decay. Instead, it appears to act as a **moisture stabilizer**, forming where bark remains soft and spongy, but not yet decomposed. In Tir na nÓg, its growth is notably more common near ritual glades, whispering pools, or stones that mark ancestral reflections. Its presence in these locations is interpreted not as sentience, but as a sign of harmony between environment and past emotion. As it absorbs water from both air and substrate, it also maintains surface humidity—supporting nearby mosses and deterring fungal overgrowth.

APPEARANCE/PHENOTYPE
Cuinín Geal forms irregular, gelatinous fruiting bodies that emerge in loose clusters or lobed folds along fallen branches or decaying wood. Its consistency is soft and tremulous, with individual structures appearing semi-translucent and ranging in coloration from pale gold to deep yellow-orange. Surfaces are often smooth and moist to the touch, with a slightly waxy sheen when fresh. Unlike rigid bracket fungi, Cuinín Geal retains flexibility, collapsing inward during dry periods and rehydrating readily with rainfall.   The fruiting bodies are relatively small in mass but can accumulate in noticeable clusters, particularly in shaded and humid environments. While delicate in texture, they are resilient, persisting through repeated wet-dry cycles without rapid decay. Their growth does not significantly damage their host substrate, instead forming as opportunistic saprotrophs that take advantage of high moisture availability. In ecological surveys, their appearance is noted as an indicator of consistently damp microclimates with stable canopy cover.
