Re : Hyaloscypha sur Typha latifolia
Hi Luc,
The hairs are Cistella, the yellowish encrustation leads to C. calyptrata, but the spores are too long for that. The sporesize fits better to C. typhae but there is no resineous matter described. you should test if the resin on top of the hairs is reddish brown in Melzer reagens. If not it is C. typhae.
Cheers,
Stip

Re : Hyaloscypha sur Typha latifolia
No reaction of hairs to Melzer. It's Cistella typhae. Thanks, Stip.
