Heyderia key
Pavol Palo, 21-06-2015 22:10
Hello friends,

Can you help me find the key to determining the genus Heyderia ? I do not have confidence in distinguishing Heyderia cucullata (Batsch) Bacyk & Van Vooren and Heyderia abietis (Fr.) Link. It's true that vary in size apothecia ? (H.abietis  2-3(5) mm , H.cucullata  up to 10 mm)

many thanks in advance!

Palo

Palo,
tohle znáš? Podle toho clánku by H. abietis mela být synonymem H. cucullata.

Re : Heyderia key
Yes I know Zuzka

"Description macroscopique :
Ascome en forme de massue de 8–25 mm de haut, constitué d'une tête mesurant
2–5 × 1–3 mm, de forme variable en fonction du degré de développement : ovoïde pour
les exemplaires très jeunes, puis campanulée avec peu de stries et anfractuosités, et finalement
nettement atténuée avec de nombreux plis et sillons."

But the description is not an option to be apothecia longer than 5 mm. Than see these awards?
