Re: Lecanora saligna Group Species?

Rereading Boom & Brand (2008) The Lichenologist 40(6): 465–497 as holiday reading (!), I think this may actually be Lecanora sarcopidoides ; this has similar spores and micropycnidia and does look similar in macro characters https://www.verspreidingsatlas.nl/7362 . If so, a very rarely recorded spec...

Lecanora saligna Group Species?

In March I collected a Lecanora species from lignum on a fallen Sweet Chestnut trunk in Studley Park, Fountains Abbey, Yorkshire. This appears to be a Lecanora saligna group species but I can not fully match it to any species description, however, it does appear similar to poorly developed material ...

Re: Cladonia coccifera?

Bob As you say nothing is ever simple with Cladonia . These are very probably Cladonia diversa , but other species in the group can occur in high quality sites thoughout Britain. I have had Cladonia borealis proved by TLC from the New Forest and here there are also wide cupped Cladonia coccifera s. ...

Re: Stumped, or sleepered

Chris Yes on I am wrong on the Buellia ocellata , suggestion. The C + yellow reaction should narrow things down, these are not common. However, I can not think what it is but does not match any typically lignicolous species I know, so I suspected it may be a mainly saxicolous species; I know these l...

Mycomicrothelia atlantica

A nice find during my recent job surveying Coedydd Maentwrog NNR, on the south facing side of the Vale of Ffestiniog was Mycomicrothelia atlantica . This is a little recorded Hazel Black Dot of hyperoceanic woods but it is actually quite a distinctive one. A few years ago I found it new to Wales on ...

Re: Stumped, or sleepered

Chris The yellowish thallus and black apothecia looks like Buellia ocellata , the C + reaction (but ideally should be orange rather than yellow), the colour of the apothecia cross section matches and your stained spores are clearly one septate (when you looked at the spores in water they looked simp...

Re: Lecanora hybocarpa an overlooked lichen

More on Lecanora hybocarpa . I recently collected a recently dead Aspen branch from Ashurst Wood on the open New Forest and went through it at leisure. This added Caloplaca cerinella , with c 16 spores in the asci, probably common in the wider countryside but new to the open Forest. 2019-05-14-01.jp...

Ochrolechia parella/pallescens on trees

Late last month Andy Cross and I were doing some vascular plant recording for Atlas 2020 on the New Forest near Ipley. Not finding much new, we strayed in to a small area of pasture woodland, which had some wood edge veteran Oaks. These are quite rare in the New Forest as the general expansion of th...

Re: Schismatomma graphidioides

I found another Schismatomma graphidioides colony on a young suppressed Beech in Ferny Crofts, New Forest this Wednesday, after rain. The wet apothecia showed the slightly raised paler thaline margin much more clearly than in dry material: 2019-05-08-02.jpg Wet Schismatomma graphidioides , with the ...

Re: Cliostomum, sac fungi or other

Paul

Does not look much like Cliostomum griffithii, and does not ring any bells, I suspect it is not a lichenised fungus
