non-lichenised but lichen like
Found a fork forgotten in the garden decades ago and covered in a black 'thallus' with elongated apothecia that follow the grain of the wood. There are some green algal cells mixed with the fungal hyphae in the 'thallus' but I don't think it is a lichen as there is no continuous algal layer. Spores ...

LF on Baeomyces rufus
Looking back at some photos from NY7807 Westmorland I came across this lf on Baeomyces rufus and just wonder if anyone can name it, next time I'm in the area I'll take a sample.

Re: Nectriopsis physciicola
Thanks Paul, It is more like Nectriopsis than Paranectria with 1 septate spores but they are on the large side. They look very much like the photos you uploaded to Fungi of Great Britain and Ireland. However, the description has (14) 15-20 (23) x 5.5-8. In the ascus mine are 19-20 x 8-8.5 and ...

Nectriopsis physciicola
I was leading a lichen walk at a tree event in Petersfield SU7524 yesterday and came across small red hairy perithecia on one thallus of Physcia aipolia. These appear to be Nectriopsis physciicola, I only had my phone with me and the image is much degraded from what was visible under the hand lens ...

Cresponea/Lycanographa/Lecanactis on sandstone
Pruinose lecideine apothecia on a very thin thallus on sheltered sandstone Ormside, Cumbria NY6917
It reminded me of Cresponea premnea and I saw that this species has been recorded from rock. The spores are (3)-4-5 septate and around 22 x 5-6mu but are too rounded for C. premnea.
I've tried C, K, P ...

lf on Phaeographis dendritica?
Came across what looks like an lf on Phaeographis dendritica (black under the lirellae), the spores of the lf were not abundant but look like an Arthonia, but are too big around 22.5 mu and 5-6 septate. My other thought is that it is a bark fungus erupting through the lichen. Linchmere common ...

Teloschistes chrysophthalmus
I was out checking on 'my' individuals of T. chrysophthalmus along the crest of the South Downs in south-east Hampshire yesterday. It is very easy to spot at this time of year in the hawthorn and blackthorn bushes. I had about 20 to check on, but all but one had disappeared and that was looking very ...

Scytinium biatorinum ?
Small 0.1-0.4mm, apparently discrete sterile granules/squamules on vertical oolitic limestone, Petworth Church, West Sussex. Wet bright green and swollen. Dry dark grey-bluish green and wrinkled. I've never come across anything like this so welcome any ideas.

Re: Bacidia absistens?
I've got a bit of a Heath-Robinson polarising set up of an old SLR polarising filter over the light source and an old piece of polarising sunglass lens over the coverslip. It works to x200 for Lecanora crystals. At x400 the working distance is too short to fit my slip of plastic between the ...

Bacidia absistens?
Collected during the Cumbria Lichens outing to Lodore, Borrowdale last week. On sessile oak bark. Very long spores 40 to more than 70mu mainly 55-70 mu x 3-3.75 mu. I sectioned a pale apothecium that seemed to key to Bacidia laurocerasi and go a little purple with K, but sections of an almost black ...

Re: Chaenotheca trichialis v. C. stemonea
Thanks for that, a new record for the vice-county. It was only on my third visit to the tree over the last couple of years that C. stemonea occurred to me after twice putting it in the 'for later' box
