On gorse - fungus or lichen?

[JennyS]

Found this small, velvet-like one on dead gorse yesterday - is it a fungus or a lichen?
The patch (A) was about 2.5cm long, the other photos were taken with a compact through the eyepiece of dissecting microscope so apologies for poor quality.

I first thought it might be more Chaetosphaerella phaeostroma (IDed here a while ago) but when I compared specimens of both through the microscope they seemed different........

Do you have Black Bears in SW Ireland by any chance Jenny ?

You realise don't you, that you are really pushing me beyond the realms of my limited experience, but it can only do good by forcing me to use my reference books.

All I've been able to find is something called Hyalosypha dematiicola but this only seems to be known from Fagus and Quercus and it is only the conidial stage which produce dark hairs, but I doubt very much this is what you have found.

Sorry I can't be of more help.

Neil.

Only very, very small ones!

Thanks for diving bravely into your reference books again Neil but it looks like this will probably have to be yet another for the 'unknown' folder.

Memo to self: Must try and avoid noticing all these tiny un-identifiable things!

If Chris Yeates was reading this, he would tell you to keep up the good work.
All I'm going to say (tongue in cheek) is "It's time to move on to BIGGER things."

Where is Chris? Hope he's OK. Missing him on here.

I would imagine it's a simple reason of not having the time to answer all the enquiries and needing free time for yourself.

This is why I am so grateful to Andreas for giving WAB so much of his valuable time.

Hi,

thank you, but why do you think that my time is so valuable that it is "spoiled" here? Or do I misunderstand this.
I'm here because I like to look at other peoples finding, to get knowledge what people find in other countries. And especially for my own courses it is always interesting to see what problems or misunderstandings in determination of species can arise, because you all reflect the whole of my participants of the courses. Sometimes one becomes blind for the problems one had in the beginning, and that would contradict my profession. So see it as a kind of gratuit training

And, by the way, there is always something new to learn. I only want to name one example in this connection, Chris Yeates, who told me lot of things yet which I didn't heared of before (still searching that parasite on Exidia glandulosa! - where are you, Chris?!)

best regards,
Andreas

best regards,

That's a lovely response Andreas.

Thank you.

Hi,

I found something similar on a dead hibiscus branch:



I was told it could be something like Harpographium.

Cheers,
Martin

Hi Martin
I do not know anything about Haplographium (I think we need Chris for this one, I hope he is OK), but there are two references in Ellis & Ellis (1985)

One other under Peroneutypa heteracantha (p38) of the perithecia "are accompanied by spine-like groups of sterile brown hyphae or by synnemata of the Harpographium state" & "Harpogaphium conidia hyline, falcate 11-15 x 1-2" On dead branches of Acer, Alnus, Crataegus, Cytisus, Euonymus, Fagus, Fraxinus, Lupinus, Rubus, Sambucus, Tilla, Ulmus etc."

The other indexed as Harpographium but as Haplographium in the text: this is under Dematioscypha dematiicola (p.214) "Haplographium state very common all the year round, the dark brown to black conidiophores up to 250 long, forming effuse colonies" "Conidia hyline 2.5-4 x 1-2 Apothicia found Oct. - Apr. on fallen dead branches"


I have not been able to find any photographs!
