No 2 of three crustose lichens

No 2 of the three crustose lichens in this photo is very small indeed and is at the bottom of the upper white patch. It is a green crustose lichen of irregular shape measuring approx. 6mm x 8mm with a few black apothecia. It looks a bit like Fuscidea lightfootii. It may be just too small for identification.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

There are problems with bleach these days, as other chemicals get added and manufacturers don't necessarily give any details. What you actually want is calcium or sodium hypochlorite. Cheap, thin bleaches or Milton baby-sterilising fluid* are generally OK but a bit weak and must be used fresh.

* As all babies are basically slimy, this seems a good idea to me.

Then you want a way of carrying it. I found that Boots** had a special offer of eye-drops in small, plastic bottles, cheap enough for me to buy a few, empty out the drops, wash out very thoroughly, and then fill with bleach or KOH and carry in a small tin.

** Other chemists are available.

I used to be lazy about carrying chemicals, but I shouldn't have been. It really does help. (Of course, one needs to know what reactions to expect, but my battered, field copy of Dobson fits nicely in the 'poacher's pocket' of my field jacket.)

Thanks for the correct ID and the tips

Thanks for the correct ID for this little lichen and for the tips on where to get suitable small bottles for carrying chemicals and for using Milton and/or other bleach. These three lichens are the first I've come across that I needed chemicals to help me, but this particular one is so very small I didn't try it.

Thanks from me too

It's interesting to hear about solutions to carrying chemicals. I somehow arrived at 10ml amber glass dropper bottles ordered on eBay, firmly encased in holes ('drilled' by hand using forstner bits) into dense packaging material (expanded polyethylene I think). The block sits in a side pocket on my rucksack and I usually unscrew the droppers without removing the bottles. I started with Domestos and NaOH, and now use Milton and KOH.

You are both very helpful.

You are both very helpful. Thank you.

Never having done any chemistry at school and therefore not understanding much about the subject I am rather wary of carrying any 'unknowns' about with me. I do understand bleach and can cope with that one, but NaOH or KOH I'm not so sure about.

I like hearing the methods that you both use for carrying them safely and will see what I can come up with.
