Pertusaria pseudocorallina

Observed: 4th November 2009 By: lpearcelpearce’s reputation in Fungi and Lichenslpearce’s reputation in Fungi and Lichenslpearce’s reputation in Fungi and Lichens

Would like conformation on this one. It looks very like my post Pertusaria corallina see http://www.ispot.org.uk/node/9802.
But the chemical tests suggest P. pseudocorallina.
Is that sufficient for confirmation?


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

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

Species interactions

No interactions present.

Not necessarily as there are

Not necessarily as there are other white crustose species that also give C-, K+ yellow going red ..... have you got a photo you could post?

Added: Sorry, my browser must have been slow loading and I didn't see the photo in time - looks ok for P. pseudocorallina.

Other white crustose, C-, K+ yellow going red species include Pertusaria aspergilla and P. coccodes.

Thanks Jenny,

Never really thought it would be that easy!.
I have uploaded a photo giving a little more detail of the structure.

The saying 'fools rush in

The saying 'fools rush in where angels fear to tread' comes to mind at this point - directed totally at myself!

Second photo seems to show yellowish soredia - is it from the yellowish patch visible in the left hand side of your original photo?
I wouldn't suggest P. pseudocorallina having seen this close up photo, but to be honest I'm not experienced enough to try and ID most unseen crustose lichens from photo's as I'm only slowly getting to grips with them myself.

Sorry Les, but from here on it would be a case of the blind leading the blind with this one .....it needs someone with more experience than me!
