Candelariella efflorescens, commonly known as the powdery goldfleck lichen, is a species of lichen in the family Candelariaceae. Found in North America, it was formally described as a new species in 1978 by Richard C. Harris and William R. Buck. The type specimen was collected by the second author from Hog Island Point State Forest Campground (Michigan, USA); here, at the edge of a swamp, it was found growing on Populus balsamifera. The lichen has a temperate eastern North American distribution. Although it occurs most frequently on bark (usually from deciduous trees), it has also occasionally been recorded growing on wood. Before its description as a new species, it had most often been confused with Candelariella xanthostigma, Candelariella concolor var. effusa, and Lepraria candelaris when well developed.

09Environmental DNA1 detections
Where the DNA of Candelariella efflorescens was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
