Bonjour à toutes et tous,Pourriez-vous me donner
I was happy to find these orange asmocyetes which at first glance I identified tentavely as Pithya vulgaris based on the size of the apothecium that ranged between 3.5 to 5.5cm and the substrate being a woody twig. P. cupressina, which I am familiar with, are here found of fallen leaves of Cupressus sempervirens and are up to 3mm wide (mostly barely 2mm).Can I assign this finding to P. vulgaris or I still need further verifications (microscopical investigations).
https://www.zobodat.at/pdf/Mycologia-Bavarica_10_0055-0062.pdf
After reading the paper, these are the most important features to distinguish P. cupressina and P. vulgaris (considered distinct species).
Spore Size (at maturity)
Pithya cupressina:Â (9) 10-12 (12.5) um
Pithya vulgaris 12-15 um
Substrate SpecializationÂ
Pithya cupressina:Â Cupressaceae (e.g., Chamaecyparis, Cupressus, Juniperus, Sequoia, Thuja)
Pithya vulgaris:Â Pinaceae (usually Abies species, occasionally Picea, Pinus)
Size of Apothecia
Pithya cupressina:Â 2-5 mm wide
Pithya vulgaris: (5-) 10-15 mm wide
My finding was on an unkown twig up to 5.5mm wide and spores with the following measurments:Â Â
9.1 [10.1 ; 10.6] 11.6 × 8.9 [9.9 ; 10.4] 11.3 µm
Q = 1 [1.0] 1.1 ; N = 27 ; C = 95%
Me = 10.4 × 10.1 µm ; Qe = 1
So it is (disappointingly) the usual Pithya cupressina which grew slightly larger up to 5mm possibly because they were growing on a woody twig, while on leaves and leaf petioles fruiting bodies only reach 1-3mm in diameter (here in Malta).Â
Eye-catching are the operculate asci !!!Â
