Patellaria atrata (?) on Juniperus
Lepista Zacarias, 23-05-2016 17:07
Hi everyone,
If I understood correctly the explanations given by Zotto in my previous topic
http://www.ascofrance.fr/search_forum/37495
this is again Patellaria atrata.
It was found in the same region than the previous (Lourinhã, Portugal), but now oudoor and growing on the roots of Juniperus at a cliff over the sea. This time I could observe living spores, guttulate, with the following dimensions:
(31.7) 34.9 - 45.4 (49.4) × (5.1) 6 - 7.4 (8) µm
Q = (4.2) 5.1 - 6.8 (6.9) ; N = 34
Me = 39 × 6.7 µm ; Qe = 5.8
I attach some photos of the specimens and from the corresponding microscopy. Someone can confirm it?
Thanks in advance,
zaca

Re : Patellaria atrata (?) on Juniperus
Yes, and it seems very rarely to occur on conifers, as I see in my literature database, while the many samples I have studied myself were all on angiosperms (woody or not).

Re : Patellaria atrata (?) on Juniperus
Thanks, Zotto, for the confirmation.
As I told in the other topic, I found these in some more or less buried wood recently lifted by some storm. I presumed that it belongs to the only shrubs (Juniperus) actually existing here, but it can be of an ancient tree/shrub.
Regards,
