Lichens on the Tombstones

Last week I showed you a few of the lichens I've seen on trees at the cemetery.  How about the tombstones?  Actually very few of them have any lichens at all, but on a few there are some quite neat orange lichens.  Obviously the type of stone used makes a difference.

These are three of very few tombstones that I've seen lichens on.  Come summer I'm going to have to have a closer look at the differences.

Here's a small patch at the base of one monument.

And have a closer look - remarkable pattern!

Another two patches on another monument.  All of the lichens on gravestones seem to be bright orange.  After Woody, of 'In Forest and Field' suggested it, I found I did have on my shelf the Lichens of the North Woods by Joe Walewski.  And I think I've successfully identified these lichens as the 'Elegant Sunburst Lichen' Xanthoria elegans.  Thanks for reminding me Woody!

In contrast, this is another of lichens on a Sugar Maple, just so you remember the difference.

  5. Some of the orange growths could be a green alga called Trentepohlia aurea, which grows on calcareous tombstones like limestone or marble. Although it's a green alga, it has a chemical that masks the green chlorophyll. Lots of cool growths on those stones!

  8. I now have a couple of lichen books, but they don't help much. There are too many different stages of each kind, I fear. I need a whole class.

  11. Some of them are quite pretty.
    I don't think I've seen any on the gravestones in the cemeteries I walk around. I'll look tomorrow.
