Dear Forum, dear Zotto!

I am writing a pocket-book about the Hungarian ascomycetes of
Vértes mountains.
It will include about 250 species (the relatively simple and well-known ones).
This project now turned to the finish line, i am collecting the recommended literature for
each species. My question is: what literature should be included on the Orbilia/Hyalorbilia species? In my book the following species will be included: Orbilia crenatomarginata, O. luteorubella, O. tremulae, O. xanthoguttulata, O. xanthostigma, Hyalorbilia erythrostigma and H. inflatula.

Can you recommend an existing paper about this species (rather for beginners)?

Thanks: Attila
