On a rock (perhaps grey granite) on the beach that would frequently be washed over at high tide.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Thank you Gardener.
I'm struggling with identifying rock types as well as lichens! What are 'basic' rocks and what are 'siliceous' rocks, please?
Basic rocks are those with a relatively high PH level and contain calcium or magesium carbonate - limestone, chalk, mortar, cement etc.
Siliceous rocks are more acidic - granite, slate, many sandstones etc.
You can check using lemon juice as basic rocks will 'fizz' slightly, though you might need a hand lens to see the bubbles.
Acidic or basic also applies to trees, conifers being the most acidic, willow, maples, apple the most basic-barked.
Nothing is ever simple though as bark (and rock) PH levels can be affected pollution, run-off etc
Very many thanks Jenny. Your explanation makes a lot more sense to me now.
I can see I'm going to have to carry a little bottle of lemon juice around with me so that I can try to see some fizzing! Some of my friends already see me as an eccentric so I might as well play up to it!!
I hadn't really realised just how complex lichen identification was going to be. But then that is half the fun and challenge of embarking on Neighbourhood Nature.
