Meet the Umbel Scribble Lichen: Nature’s Tiny Graffiti Artist
Have you ever noticed what looks like mysterious dark scribbles or tiny writing etched onto tree bark in your garden? Meet Opegrapha umbellulariae, commonly known as the umbel scribble lichen – one of nature’s most intriguing miniature artists that’s probably been decorating your trees without you even knowing it!
What Exactly Is Umbel Scribble Lichen?
Unlike the plants you’re used to tending in your garden, the umbel scribble lichen isn’t actually a plant at all. It’s a fascinating partnership between a fungus and an algae, working together in perfect harmony. This dynamic duo creates those distinctive dark, scribbly lines that look remarkably like someone took a fine-tipped pen and started doodling on tree bark.
As a native North American species, this little lichen has been calling our continent home long before any of us started gardening. It’s particularly fond of making its home on the bark of various trees, where it quietly goes about its business of being absolutely fascinating.
Where You’ll Find This Natural Artist
The umbel scribble lichen has a particular fondness for western North America, though its exact range extends throughout various regions of the continent. You’re most likely to spot it making its artistic marks on oak trees, though it’s not picky and will set up shop on other tree species as well.
How to Identify Umbel Scribble Lichen
Spotting this lichen is like going on a treasure hunt in your own backyard. Here’s what to look for:
- Thin, dark lines that zigzag across tree bark like abstract writing
- Black or very dark brown coloring that stands out against lighter bark
- Scribbly, irregular patterns that never seem to follow straight lines
- Small size – these drawings are typically just millimeters wide
- Preference for the bark of mature trees rather than young saplings
Is It Beneficial to Your Garden?
Absolutely! While you can’t plant or cultivate umbel scribble lichen like your roses or tomatoes, having it show up naturally in your garden is actually fantastic news. Here’s why you should be thrilled to discover these tiny scribblers:
