More random lichen

[JennyS]

Q1. Pertusaria? On hazel (I think) in Glengarrif woods




2. Leptogium - wondered L. britannicum but the lobes seemed more substantial than in photos I compared with. With moss on coastal rock




3. Better candidate for Physcia stellaris? Same location as the intermediate-looking ones I posted a while back




4. Punctelia Q1 on shaded branch of either Salix or Alder in wet woodland - couldn't re-find to test but will keep searching ......




5. Punctelia Q2 on well-lit upland rock - went back to test but the bull was there and I'm a wimp!




6. Slipped in slightly apologetically - a coastal crustose query

Hi Jenny,

Over the next few days I hope to get out and do some more lichen photography for myself rather than this armchair identification. So this might be one of my last responses for a while.

And you've been sneaking in crusts again!

Anyhow,

1. Yes, I think so, shade form of Pertusaria hymenea.

2. I have not seen L. britannicum, nor most other species of the genus yet, but L. britannicum seems a good suggestion. The lobes do look suitably thin to me, and it doesn't appear to be showing any inconvenient features.

3. I agree.

4. Oh yes, nice Punctelia subrudecta. Many records in the UK, and a number of published photographs, are now known to be P. ulophylla of course. However, yours is the genuine article.

5. One I have not seen yet but this must be Punctelia borreri. You show the black underside, and those smaller, sunken, young soralia on the lobe surface are a good match to the photographs on the BLS Parmelia CD. I feel reassured I am not overlooking it now.

6. Oh yes, I know this sort of thing. I mutter "Porpidia" (though I do this for anything with black apothecia), I photograph it, I chip a bit off and take it home, when:
a) I have a go at it and find the asci are immature and I cannot even be sure of the genus,
or
b) it stays in its packet until that day that I know will come sometime, just not today or tomorrow, when I will finally sit down for a serious Lecidea/Porpidia/Lecidella/Sarcogyne/Rhizocarpon session.
I also notice that the better my initial photograph, the less chance I have of getting a name for it later.

Oh, wait a minute, you mean the black one? Or the yellow one? The white one with black apothecia is just a splodge you are not interested in? (He says hopefully, but fearing otherwise.)

(For others reading this thread, the black one is Verrucaria maura and the yellow one is Caloplaca thallincola, both standard on coastal rocks.)

Thanks Alan, and sorry about the crustose beastie - they just sit around goading me to take yet more photo's that I know I haven't a hope of IDing and like a mug I can't resist.....

4. Now I'm a bit concerned about some of my other P. subrudecta ID's.....is the one below also P. subrudecta or I have I also muddled them?



Hope your Cladonia trip goes well, but you'll be sorely missed here!

No problem, this is also P. subrudecta.

I have decent photographs of both species, so maybe I'll put them up on my site for comparison later this month.
