Lichenicolous fungus on Pertusaria pertusa - 2015-10-03
Lepista Zacarias, 06-10-2015 20:04
Hi everyone,
I found this lichenicolous fungus growing on the thallus of Pertusaria pertusa. It is a pyrenomycete having simple spores with many guttules inside, of dimensions:
(19.9) 21.3 - 25.8 (27) x (9.5) 10.6 - 12.6 (13.8) µm
Q = (1.7) 1.8 - 2.3 (2.5) ; N = 30
Me = 24.2 x 11.6 µm ; Qe = 2.1 .
The list of lichenicolous fungus on Pertusaria is very long, as can be seen for instance in Lichenicolous net. I have tried without success to find there anything similar.
Anyone have any suggestion of what this could be?
Thanks in advance,
zaca

Dear Zaca, 
I would not say this fungus is a lichenicolous one! The lichen is Pertusaria pertusa as you say but the fungus seems to be an stromatic lignicolous growing under the lichen. I do not know it.
Best wishes. Javier

Thanks, Javier.
I think that you must be right, but my first impression was that it was lichenicolous.
Maybe someone else has an idea of what it could be.
Regards,
zaca

Javier is right, I think that it could be a Botryosphaeria species, a lignicolous fungus.

Thanks, Alain, for helping me once more.
After your comment I search for information and found the site
http://www.crem.fct.unl.pt/botryosphaeria_site/index.htm
where I could see some species similar to my specimen. Unfortunately, the key present there is based on the properties of conidia, which I didn't observe.
Best regards,
zaca
