Lichenicolous fungus on Ochrolechia parella

This has the look of a Monodictys species with a substantial branching structure. Terminal cells are mainly 1-septate. Cell widths: 5.9-8.2 µm

Basal colour is orangey becoming olive-green/brown towards the apices.

Any thoughts welcome.

Re: Lichenicolous fungus on Xanthoparmelia mougeotii

Heather, welcome to the forum.

Do you have any macro images?

You might want to consider Pyrenidium actinellum.

Regards, Chris

Re: Galerina clavata confirmation

I agree with Chris, your third image shows a more convincing range of spores.

I can't compete with Chris's wonderful DIC photographs, but there are some here your might find useful for reference.

Re: One to look out for

Now much farther north ... on the first leaf I picked up :shock: Thanks for bringing this to our attention. Chris It took me over 30 leaves!! Your leaf looks brown. Was it still slightly leathery as if it hadn't been fallen for very long? Fay Yes, just as you describe. I looked at about 40 'promisi...

Re: One to look out for

Interesting reading: sequencing has produced some unlikely associations. Makes life challenging for the amateur.

Re: One to look out for

Hi Chris

Although a long way north, Griselinia littoralis is planted up here too. When this spell of foul weather has passed, I will take a look. It may be that the gales will have removed most of the litter unless I can find a shelted spot.

Re: Opegrapha atra

Many thanks for the list Mark. General question - might it be worth submitting a request for a separate Lichenicolous Fungi section as it could be really useful to keep these posts together for easier searching and reference? An excellent idea, Jenny. I'm surprised nobody has commented, perhaps our...

Re: Two moss IDs

Since my original post, I have now purchased the BBS's excellent Field Guide: "Mosses and Liverworts of Britain and Ireland". As others have noted, it is very clear, comprehensive and provides an excellent steer. Highly recommended. I can now dismiss homalia trichomanoides. Now you have the field g...

Re: Phylloblastia

I've only ever seen Phylloblastia species on living leaves. They seem to like the waxy coating of holly leaves and I know they've been seen on other waxy evergreen leaves too. Neil and Mark will know more. Thanks, Fay. I will look out for it next time I go to Stornoway, although way outside its kno...
