Même site, haute Ardenne. Sur gaines pourrissantes de Typha.
En groupes parfois nombreux. Apoth. en grelot puis presque planes, hyalines, tendant à jaunir en vieillissant, -> 0.5 mm. Excipulum poilu, poils blancs/hyalins.

Asques trapus, 8-sp., sp. bisériées, IKI BB, 14-26 x 4.5-5.5(6.5) µ.
Sp. 0-1-septées, hyalines, 6-10(12) x 1.5-2 µ.
Paraph. minces, hyalines, ne dépassant pas les asques, x 1 µ.
Poils à paroi mince, granuleux, courts, 11-21 x 2.5-4(5) µ
Exc. ectal text. glob.

Pas d'idée non plus. Il me reste beaucoup à apprendre :/

Amitiés - LUC.

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

Hi Stip,
Okay, I'll check that detail and will tell you.
Thanks for your advice.
Cheers - LUC.

Re : Hyaloscypha sur Typha latifolia

No reaction of hairs to Melzer. It's Cistella typhae. Thanks, Stip.
Cheers - LUC.
