Re: Stumped, or sleepered

Neil

Thank you for taking the trouble to reply. It's an interesting thought but I have to agree with Alan that the spores especially don't fit even closely. These were hyaline in water and much too narrow. I did another C test and it remained yellow.

Re: Armillaria

Hello Andreas

Many thanks for that. Armillaria ostoyae is on the site but the strange pink colour was misleading.

Armillaria

This was sent to me as possible Armillaria mellea but it doesn't look quite right. With the pink in the cap I was thinking Armillaria tabescens , but I have no experience of that species. The caps are not open but I see no evidence of a veil that would develop into a ring. Taken in Augst last year. ...

Have you had a look at the Haematomma key in the Flora?
No, but I have now. :)

It's not Haematomma ochroleucum, nor K+ which leaves Mycoblastus caesius which is UV+ and mine is UV-, so I think we are safe with Pertusaria albescens.

I appreciate the interest and help.

Re: Help with identification please

Thanks for that suggestion but no reaction to K.

I wonder if the soralia are too pronounced for that species?

Re: Buellia griseovirens norstictic success

I admire the perseverance, and thank you for posting.
It would be good to keep the forum ticking over while other lichenologists (at whatever level) get to know of our existance.

Re: Help with identification please

Thanks both for the health warning, I was well prepared with the porridge to follow then ... nothing ... so Pertusaria albescens it is.
