Juuso ÄikäsLast Tuesday I found some tiny white Helotiales gr
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).

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: (9) 10-12 (12.5) um
Pithya vulgaris 12-15 um
Substrate Specialization
Pithya cupressina: Cupressaceae (e.g., Chamaecyparis, Cupressus, Juniperus, Sequoia, Thuja)
Pithya vulgaris: Pinaceae (usually Abies species, occasionally Picea, Pinus)
Size of Apothecia
Pithya cupressina: 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:
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).
Eye-catching are the operculate asci !!!
