Hello, Please about help with determination. On
Sur tiges mortes de Veratrum album à 1'779 m, apothécies 0.2 - 0.4 mm de diamètre, marge et surface externe couverts de poils, asques 100 - 105 x 10 - 14 µm, octosporés, IKI rouge, avec crochet, spores 12 - 17 x 4.75 - 6 µm, lisses, hyalines, 0 - 1 cloison, paraphyses à pointes réfringentes, idem poils, jusqu'à 20 µm, disparaissent au traitement KOH 3%.
Les élements microscopiques me conduisent vers Hyalacrotes, dans la Databank il y a une espèce (Calloria gentianae) qui ressemble à la mienne, seulement à ma connaissance les Calloria sont différentes.
Merci d'avance pour vos avis.
Elisabeth
you are right this is Calloria gentianae. I think it fits well collections in my gentianae folder (in Calloriaceae/Naevioideae, Iridinea).
Since a long time an article on this species was started with René Dougoud and Branislav Peric, but it got very delayed because the generic concept is still disputable. What we do not have so far is a sequence.
My old collection HB 2897 was on veratrum too.
Would you mind sending me your collection data?
