Rotten Designs

Rotting wood is my new passion. Where I walk in Westwoods has a greater share of dead trees than most other forest areas. It used to be dense with Hemlocks until they were killed by the wooly adelgid infestation. Now the forest floor is covered with downed trees and branches. It is truly a mess. I used to think it was ugly. But I started to see the standing stumps and logs as carved sculptures. Then I looked closely at some fallen logs and was mesmerized by the patterns. Some are made by fungi, some by boring beetles, and some by weather. Enjoy this gallery of rotting wood.

An Image Sealed With a Kiss

Crustose lichen on fallen log

I knew of course that I was photographing a log, but when I saw the isolated details through my camera, I was mesmerized by an abstract world of shapes and colors. Looking at the image afterwards, however, I began to see the white blobs as central characters. Then the characters became animals. Finally, one of the animals kissed the other.

I now know that the kissing blobs are a form of crustose lichen. Crustose lichens, as their name implies, form crust-like structures – in this case, on a rotting log. All lichens are made up of algae or bacteria (the plant part that provides the photosynthesis) and fungi (the part) that provides structure. The black outline of these blobs — a painterly effect of nature — is due to the wearing away of top structural layers, exposing the underlying threads (hyphae) that attach the lichen to the log. Learning the science of the image didn’t spoil it for me. It’s semi-abstract quality was sealed with the kiss.

Yellow!

Yellow Stagshorn
Small Stagshorn fungus reaches a height of only four inches and is tapered on the ends of the spires.

This bright yellow fungus (calocera cornea if you care to know), commonly known as Small Stagshorn, is a petite relative of Yellow Stagshorn. It grows on rotting stumps and buried roots, quickening their decay. In a forest of greens, browns, and greys, its yellow spires scream out for attention. “Look at me!” When I first spotted a clump in a muddy bog, it seemed so audacious that I was immediately suspicious of its motives and didn’t dare to even touch it. Reading about it later, I learned that Stagshorn is in fact edible in the sense of being “non-toxic,” although it is both bland and gooey so that it is generally used only as a garnish. Even if it were described as being delicious, I would never dare to actually ingest it in case I was wrong in the classification, although I did go back to touch it. Who could resist when the various adjectives used to describe it read like an entry in Roget’s Thesaurus –- waxy, slimy, sticky, gelatinous, jelly-like, and viscous. Personally, I found it to be slightly icky.

Revelation in a Piece of Wood

Slice of Spalted Wood
Spalted wood from a sawn tree.

This sliver of maple wood cut from a tree that fell over the Red Rectangle Trail looks like a map of some unfamiliar world so I was surprised to learn that it is exactly that. The squiggly black lines superimposed on the circular growth rings look like meandering rivers. Known as zone lines, they mark territorial boundaries between species of fungi competing for the dead wood. I felt a little sad to learn about this self-serving behavior of micro-organisms. The sadness made me realize that, even though I swear I never thought about it, I had assumed that fungi would share.
