Lighter fruited L. albella (top left) mixed with darker fruited L. chlarotera and very pale L. carpinea.
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.
The Field Studies Council guide and the OPAL guide are quite confusing when it comes to separating these three species - any hints would be appreciated.
Best way to help separate these (and others) is to test for the K and C reactions, details on the BLS website: http://www.thebls.org.uk/content/chemical.html
L. albella: Thallus K+ yellow, C-, discs (apothecia) C-
L. carpinea: Thallus: K+ yellow, C-, discs C+ yellow or orange. Discs +/- white pruinose.
L. chlarotera: Thallus K+ yellow, C-. Discs usually browner in colour than for the other two species.
For most of the crustose species chemical tests are vital to help with IDs - there are so many very similar species that its often not possible to accurately identify them visually.
Thanks for the coaching (as usual!)
The Lecanoras are so unbelivably similar that I can finally see that tests are essential if you really need to be accurate. Must go on some proper training, or quit.
Go for the training - you're starting to get your eye in for lichens so it would be an awful shame if you quit!
