Guepinia helvelloides: The Ultimate Mushroom Guide
About The Guepinia helvelloides Mushroom
Guepinia helvelloides is a widespread fungus easily recognized by its unique shape, rubbery texture, and orange to salmon-pink coloration. It is a saprobic jelly fungus that is unique as it dries out, yet rehydrates repeatedly as the rains come and go. Interestingly, they produce a new set of spores each time they rehydrate.
This mushroom is reported to be edible but very bland and of little or no culinary value.
Other names: Apricot Jelly, Apricot Jelly Mushroom, Candied Red Jelly Mushroom, Salmon Salad.

Guepinia helvelloides Medicinal Properties
Anti-tumor activity. Polysaccharides extracted from the mycelial culture of G. helvelloides and administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 100% (Ohtsuka et al., 1973).
Guepinia helvelloides Taxonomy & Etymology
In 1778 Dutch botanist Nicolaus Joseph von Jacquin (1727 - 1817) described this fungus and gave it the binomial scientific name Tremella rufa. It is currently accepted scientific name dates from Elias Magnus Fries' Systema mycologicum of 1828.
Synonyms of Guepinia helvelloides include Tremella rufa, Tremella helvelloides, Tremiscus helvelloides, Guepinia rufa, Gyrocephalus helvelloides, Gyrocephalus rufus, Phlogiotis helvelloides.
Some authorities place the genus Guepinia within the family Exidiaceae.
