Re: Lichenicolous on Ochrolechia parella

Thanks for the reply Chris.

I couldn't understand why I had no spore details but finally managed to find the specimen and realised why - a scrappy collection of rock crumbs with a note on the packet saying "gone mouldy, no spores found".

So not a hope!

Lichenicolous on Ochrolechia parella

I came across this photograph of a lichenicolous fungus on Ochrolechia parella, coastal SW Ireland 2012 and wondered if anyone might have come across anything similar on Ochrolechia to suggest a possible identification? z spC1 1201310012 Och parella.jpg z spC1 1201310012b Och parella.jpg z spC1 1201...

Re: What is the current name for Daisy Rust

Hi Posch - it looks like the answer might depend on the source you use. Here's a link to Bladmineerders where the jury still seems to be out as regards the occurrence of Puccinia lagenophorae on Bellis perennis: https://bladmineerders.nl/parasites/fungi/basidiomycota/pucciniomycotina/pucciniales/puc...

Yes, that's Nostoc - probably N. commune but there are others.......

Re: Help with identification please

Hi Chris - be warned, only taste a very, very small amount as if its Pertusaria amara it is most horribly bitter!

Myxo on Oak leaf

Came across this myxo on an oak leaf today and wondered whether identification (at least to genus) might be possible? Surface was powdery / granular, stipe absent, spore diameter 10 µm. Externally it looked similar to Mike's image of Badhamia macrocarpa but I'm totally ignorant when it comes to slim...

Re: Perithecia in slits on Oak

Thank you for the reply Paul - I did look at Chaetosphaeria ovoidea but had discounted it as the perithecia appeared to be erumpent rather than superficial. Below is an image of the ascus tip that I hope might help - I tried with both Lugols and K+Lugols to see if there was a blue reaction but appea...

Perithecia in slits on Oak

Its been a while since I've looked at microfungi and I'm already struggling! Multiple perithecia in slits in a fallen oak branch, spores hyaline, 3-septate, 17-22 x 5-6 µm. Paraphyses present, asci without croziers. Help appreciated - but am I missing something obvious in Ellis & Ellis? z Q1 190312 ...

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?

Re: Cladonia macilenta or polydactyla

Hi Christine -they look like the sort of Cladonia I'd avert my eyes from and try and find more mature specimens! Alan Silverside said when testing for a K reaction it is best to test the lower portion of the podetia as apothecia and pycnidia of all red-fruited Cladonia species give K+ red to purple ...
