Small clavate hairs, negative croziers and IKI bb
Good nightI have this small (< 6mm diam.) Peziza, without stipe, growing in a slope of a path, inside a "Botanical Garden" in Portugal. I have a previous collection of P. apiculata but I think this one does not fit.
Spores measurement (without "apicula"): (19.2) 20.0 - 22.8 (24.1) x (8.0) 8.4 - 9.6 (10.2) µm; Q = (2.1) 2.2 - 2.5 (2.8) ; N = 77; Me = 21.3 x 9.1 µm ; Qe = 2.4
Asci with croziers, truncate apex and amyloid in all the surface.
Thank you in advance.

What a variable species!!!! I had this another collection like P. apiculata (11/07/2014), with differente spores, ornamentation and apicules; and this spores measures (including apicules):
(22.4) 23.7 - 27.3 (28.9) x (7.8) 8.8 - 10.6 (12.2) µm
Q = (2.1) 2.4 - 2.9 (3.2) ; N = 85
Me = 25.3 x 9.7 µm ; Qe = 2.6
All spores of this collection of 2014 had very regular apicules shape and size. But actual collection 2015 has very irregular apicules shape and size.
Is there any clear character to separate P. apiculata from obtusapiculata, polarispinosa, vagneri, thozetii ...?
Thanks again.
Hola Miquel,
what you show in your picture is P. obtusapiculata.
best regards,
Andreas
You are talking about the second one, aren't you? So, first one is P. apiculata, second one is P. obtusapiculata.
Any actual paper about this group?
Danke.
hast du von P. vagneri auch so eine Sporenzeichnung?
Gruss
Ueli
Hallo Ueli,
nee, tut mir leid, P. wagneri kenne ich leider nicht, auch die anderen apiculaten Arten nicht.
beste Grüße
Andreas
