The decurrent gill like structures are orange and forked, which is a distinctive and distinguishing feature. The spore print is white. The orange stipe is up to 5 cm high and lacks a ring. ref name phil85 Distribution and habitat It is widely distributed in Europe and North America, being found in both hardwood and conifer forests, in summer and autumn. It fruits from the ground or from decaying wood. ref name mill06 Edibility It has been described as edible though not tasty by some experts, but other authors describe it as poisonous. ref name mill06 This mushroom contains high levels of arabitol , which may account for the gastrointestinal symptoms some people experience. Recent taxonomic research has demonstrated that Hygrophoropsis is a close relative Paxillus , a genus that includes Paxillus involutus , a species known to have cumulative autoimmune toxicity. Hence, some guides recommend avoiding consumption of Hygrophoropsis as well. ref name suo Similar species File Hygrophoropsis.aurantiaca2 ... more details
