Edibility

Not edible

Consumption of this species is controversial as status ranges from edible to poisonous; it has been linked to an old poisoning report in China and should be approached with caution. Every part of the mushroom, including the flesh, stains black when bruised, handled, or aged. It can be confused with Hygrocybe conicoides, which also likely contains toxins but prefers sandy dune habitats and turns black more slowly. Other similar red or orange waxcaps like H. cuspidata and H. acutoconica can be distinguished by their tissues which do not blacken.

Misidentification can be fatal. Never eat a mushroom unless you're 100% sure. This information may be inaccurate. Always consult multiple sources.

Nutrient Source

other

This fungus appears to have a biotrophic lifestyle, obtaining nutrients directly from living plant tissues. It is not a saprotroph that decomposes dead organic matter.
