More Cladonias

[Tiggrx]

A couple more for ID if possible please. I haven't been able to come up with any sensible suggestions by myself

On a rotting log in Sherwood Forest, Notts


On a wall in Kielder Forest, Northumberland


Thanks
Aaron

Very very tentatively as I think I'm getting totally scrambled by Cladonia did you consider C. bellidiflora for 1. and C. polydactyla for 2?

I know how you feel

Yes, however I don't think Sherwood Forest is a likely area for C. bellidiflora which I think is usually an upland species. Certainly out of range judging by the map in Dobson

I didn't and I guess it could be

Jenny, thanks yet again for all your help

Not sure how much help I'm being as I completely forgot to check habitat location when suggesting bellidiflora!

I have got to say that for no. 1. my first thought was also C. bellidiflora, and I'm pretty certain from one of the American Robin Hood films that Sherwood Forest does have mountains.
There is also a dot on the NBN Gateway map for C. bellidiflora from the Esher area of London, though I regret to say that the source of this is NOT reliable for lichens.

However, despite its very strong resemblence to C. bellidiflora, it is too grey, and more importantly the upper parts of the podetia look like they pretty definitely have powdery soredia. This latter character knocks out C. bellidiflora, and takes us back to C. polydactyla in one of its many guises.

Number 2 is indeed also C. polydactyla. The apothecia are a bit small and rather button-like, and I was going to make a case for C. macilenta, but it is rather too squamulose and, critically, in the foreground and partly out of focus there is a definite irregular cup of polydactyla type.

Thanks Alan. I have some other photos that I think may be C. macilenta but they are poor pictures and may not be good enough for ID - I will see what I can do with them later.

Dunno if it will help, but Cladonia macilenta is now up on my site, with some notes on separation from similar species.
