Xeromphalina tenuipes

Golden Trumpets

(Schwein.) A.H.Sm., 1953

Detailed Texts Multi-lang
A small, delicate wood-rotting fungus easily recognized by its convex to slightly depressed, golden-yellow to tawny-orange cap that features a distinctly velvety or minutely fuzzy texture. The prominent yellow gills run slightly down the slender, tough, reddish-brown stem, which is typically covered in fine hairs near its rooting base.

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Grows primarily in clusters on dead, decaying logs and fallen branches of broadleaf hardwood trees, especially oak and beech, within moist temperate and subtropical woodlands across North and South America.

SubstrateThe organic material or host organism this fungus colonizes and decomposes. Multi-lang

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

A lignicolous saprophyte that actively networks inside rotting tree trunks. It persists underground or inside timber as mycelia over multiple seasons, producing seasonal flushes of trumpet-like bodies in response to persistent ambient dampness.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

The dense velvety hyphae coating the cap and stem help reduce surface evaporation and preserve moisture within the small fruiting body during minor dry spells in the forest understory.
Possesses a physically tough, fibrous stem structure that anchors tightly to hard wood grains, allowing the tiny mushroom to withstand mechanical disturbance from wind or rain.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Intensive logging and aggressive forestry cleanup routines that systematically strip fallen logs disrupt the specific microhabitats required for long-term vegetative mycelial growth.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

The species name 'tenuipes' translates literally from Latin to 'slender-footed' or 'slender-stemmed', highlighting its remarkably thin yet robust and resilient stipe structure.
