Myxarium nucleatum (common names crystal brain or granular jelly roll) is a jelly fungus in the family Hyaloriaceae. The sporocarps (fruit bodies) are watery white and gelatinous with small, white, mineral inclusions. It is a common, wood-rotting species in Europe and North America, typically growing on dead attached or fallen branches of broadleaf trees.

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.
