Re: Didymocyrtis slaptoniensis (?) on Xanthoria parietina

Thank you Mark, Your response is very informative and helpful. I now have a clearer idea of what to look for. I have looked at some sections and the red pigment is very diffuse and there is no reaction with KOH. It was always going to be very tentaive suggestion without any microscopy. So I will kee...

Didymocyrtis slaptoniensis (?) on Xanthoria parietina

This is the second licenicolous fungi found on the Rowan twig that produced Nesolechia oxypora, collected from the east coast of South Uist last week. The red colouration on the thalli of Xanthoria parietina suggested the presence of Didymocyrtis slaptoniensis. Unfortunately examination of sections ...

Re: Nesolechia oxyspora

Thank you Neil, I should have said that I'd referred to the description on Fungi of Britain and Ireland. This morning I've also managed to find my copy of Hawksworth (1983) A key to the lichen-forming, parasitic, parasymbiotic and saprophytic fungi occurring on lichens in the British Isles; and chec...

Re: A Lichenicolous Fungus on Cladonia zopfii

No shortgae of C. uncialis or C. arbuscula in the Outer Hebrides. Provided that it eventually stops raining/blowing a gale, I will look for signs of Taeniolella.
I would find a Zoom tutorial on identifying Cladonia very useful.

Thanks

Re: Possibly Solenopsora holophaea ????

Thank you Paul. It's not on the compost yet, and is probably destined for an envelope with the name of Brian Coppins on the outside. I looked at your site and I also looked at Placidium squamulosum, but I think I rejected it because of habitat; the record for VC110 is from Harris and a very sandy si...

Possibly Solenopsora holophaea ????

This lichen was collected from Lingeigh, a small island off the north coast of North Uist, Outer Hebrides (NF8778), on 28 september 2020. I was not present, so I have no detailed knowledge of the habitat, but I suspect it was a peaty crevice. The island is Lewisian gneiss (siliceous) covered with pe...

Re: Two horseradish parasites

Thank you Chris for another fascinating presentation.
As soon as it stopsblowing half a gale and raining I'll have a look at our horseradish plants.
