Displacement is a common theme. Can be moving the lichen or moving the environment through disturbance. Substrates are important. Lighting is important. Moisture is important. Can lichen thrive and spread (colonize) after experiencing displacement.

Do cultural aesthetic, like painting and fireplace fashion get reflected in where lichens are present or absent?

My back fence:
North facing
Partial Shade
No stable water nearby but fence retains moisture
Substrate: Rough, weathered wood
Growth Forms: Crustose
Color: Orange and Yellow (suspected high conc of pulvinic and usnic acids in fungal cortex)

On other buildings, though, the lichens are between the windows, on columns that stand out very slightly from the building face.
- sandstone
- 20 years
- mostly algae (and mildew?) in the streaks, but lichens growing near the top of the streak

# data[].attributes.body
- Science Quad buildings
- 20 years
- sandstone, with large steel frames around the windows.
- streaks under the windows that look like algae, but close up are sparse, tiny lichen bodies
- areas around the streaks, no such growth
- buildings notorious for poor drainage, so these streaks are probably where rain water runs down

Buildings with paint and what appears to be stripped bricks showed no life of our slowly creeping friends.

At first I felt unfortunate as to find no sign of lichen on the elderly eastern facing store fronts. I was sure they would exist and that my hypothesis that diameter of lichen I find will directly be related to age of the building. "AHA" I thought, that makes so much sense!, but I could never test this or have proof to support it.

I found that this lack of proof of my hypothesis created many more questions that turned my unfortunate feeling of humility, to an exciting adventure making me late to my meeting.

Can lichens not grow on painted surfaces? Does the ideology of having a nice curbside appeal lead to the destruction of these symbiotes? (Unbeknownst to the owners that the lichens themselves could be beneficial to their environment). Are the buildings too young? How fast do lichen grow?

Apparently lichen on fireplaces was a popular home fashion craze? Limestone fireplace?

1) no lichen in newly constructued buildings
2) more lichen near the old buildings, epecially in shaded area
3) structure - boulders
4)substract - have effect on lichen
5) No iichen actually found in any buildings (may be they are removed)

General observations: lichens are not as easy to find in the human-made structures around the house. Lichens  are found mostly found on large/old tree trunks or tree branches like maple, hemlock. Older rocks did appear to have larger lichen and more diversity.
A: Foliose lichen (max. length 8.5 cm)  bright green with dark hairs growing on hemlock tree branch
B: Squamulose? lichen (max. length 1.5 cm) in tree trunk (opposite side dominated by )
C & E: Yard pebbles with very tiny light green lichen growth (max. length 0.3- 0.9 cm)
D: Light green semi-circular squamulose? lichen growth  in older-looking yard rock (max. length 1.8 cm)
F: Maple tree branch with circular white smooth (4 cm) lichen

This is off Highway 130 west of Laramie -- so automobile traffic passes this location, I believe.

One stone:
- (sandstone or basalt?), porous surface
- past twenty years
- encrusted with lichens (both foliose and crustose, pale blue, gray, and green).
- located far from auto traffic, shady spot, but lot of foot traffic. - People stand or sit on it all the time.
Other stone:
granite, smooth surface
- no lichen or other sediment.
- past five years
- people don’t sit on it
