I'm noticing some very small occurances of pale green (mint ice cream)
colored lichen growing on my little elm.

Lichens are harmless, and add to the wabi/sabi of the tree. If they
get bigger than you like, scrape off the excess. The presence of
lichens tells you that you have clean air, which is good for your
trees, too.

"The presence of lichens tells you that you have clean

I have lichens on a few of my trees here in NY city.
I must admit that they did not begin growing here but
were on the trees when i bought them. However some
have survived and not diminished but increases over
the past 6 years. I wouldn't think our air here was
that clean.....so why have they continued to thrive.
But maybe im wrong since New York City is an island.
On that note what are some of the least hardy trees in
polluted air?

This is one of those "Japanese Things" that has no direct English
translation. Basically it means "mystic" or "character." Or what ever else
someone wants it to mean.
