Poor photo quality

Sorry about the poor quality of the photos. We were using my husband's iPhone and having just started the OU Neighbourhood Nature course, was not sure how detailed the images had to be. Any help identifying these would be appreciated though.

Don't worry, you are not

Don't worry, you are not alone in finding them difficult to photograph and start identifying!

First row, RH photo might be Caloplaca flavescens, (placodioid - crustose with lobed margins).
Third row, LH photo might be Platismatia glauca, (foliose).
Above are possibilities, not definite IDs!

The following comments are intended as general rather than just in response to your post.....

I don't know what advice, lichen resources, links or keys the OU Neighbourhood Nature Course provides for its students but there must be some so they are worth taking a look at. There are also some useful links if you scroll down the RH side of the iSpot homepage.

A good way to start is to look at the photographs provided with the keys etc and get an idea of the difference between the growth forms; crustose, foliose and fruticose.

Looking at different lichens you start to become aware of the differences between them and reconise the different parts that help with IDs.

Lichens can be difficult to photograph well but unfortunately without clear close-ups showing reproductive features it often isn't possible to even begin to suggest possible identifications for many lichens from photos.
Even with sharp, detailed photo's many crustose lichens are very similar and need chemical tests or microscopy to have any hope of identification.
