Tom SchrierHi all,We found picnidia on Protoparmeliopsis mur
Encore une espèce d'altitude (2'335m), sur fleurs mortes de Cirsium spinosissimum
apothécies 0.25-0.5mm de diamètre, entièrement orange, surface externe et marge couvertes de poils, asques 75-90x9-12µm, octosporés, IKI rouge, spores 9-12x4.5-5µm (peu de spores en dehors des asques), 0-1x septées, lisses, hyalines, paraphyses filiformes et septées, poils réfringents jusqu'à 65µm, KOH 3% aucun changement.
Merci d'avance pour votre avis.

the hairs look to me more like Olla or Unguiculella with only a lumen at the base.
Please check the stability of the glassy parts of the hairs in a higher KOH concentration
(> 5% is reliable) If you do not have higher concentration try KOH boiling and see if hairs are losing refractiveness and become permeable to Congo Red or Melzer.
Are asci with croziers, I can not see from your photos.
cheers,

never seen this species too but it fits very well, perhaps this alpine finding even could be regarded as H. schachdarica as Raitviir suggests.
from the original schachdarica description.
pili 35-50 x 1.5-2.5 asci 80-100 x12-18 spores 11-13,5 x 4-6 (this 18 um wide asci appear very strange to me and nothing about Iodine reaction or croziers)
regards,
Stip
