Dacrymyces Palmatus

Day 49: It can be difficult to distinguish a specimen of Dacrymyces palmatus (Orange Jelly, above) from Tremella mesenterica (Witches' Butter) without a microscope, but if you are in the field, your best course of action is to examine the substrate on which they are growing. Dacrymyces grows on rotting conifer wood, Tremella on that of hardwoods (rarely on conifer). As Dacrymyces dry out, they tend to collapse in on themselves and deteriorate. On the other hand, Tremella shrinks and hardens. Neither species is poisonous, but neither are they considered edible (a term which implies some desirability as a food).

Day 48: Not uncommon in Pacific Northwest forests, Dacrymyces palmatus can be distinguished fairly reliably from similar Tremella mesenterica by the fact that this fungus grows on decaying conifer wood. Tremella appears less commonly on rotting fir and hemlock, preferring hardwood as its substrate. Another telling feature requires familiarity with the species in its dry state. Dacrymyces collapses in on itself like a deflated balloon whereas Tremella becomes tough and firm. This was a particularly healthy specimen of Dacrymyces, discovered off-trail during a walk from Longmire to Cougar Rock.

Dacrymyces Palmatus

Day 44: There are a number of Pacific Northwestern jelly fungi which fall under the unofficial nomenclature of "orange blobs," but Dacrymyces palmatus is likely the largest and showiest of the lot. When it is small, it could be mistaken for Tremella mesenterica. However, examination of the substrate will clear up any confusion. Dacrymyces grows on rotting conifer wood and Tremella appears on hardwoods. The outer skin of this species is leathery and tough, covering a mushy interior. When fresh and young, the lobes of this fungus are plump and translucent. As it dries out, the lobes collapse in on themselves, giving it a much more wrinkled appearance. While not actually poisonous, they have an unpleasant taste.
