Paraphyses simple, with rounded ends which are sometimes subclavate.
3-5um wide, up to 5.4um wide at apex. -- n=10,

Medium and large size cup fungi were growing on the ground in a mixed forest (burr oak, basswood, ash, sugar maple, prunus, betula, white pine, cedar…) the largest apothecium was 14cm in diameter, many were around 10cm.
Asci operculate, 8-spored, H+, uniseriate, IKI+.
Ascospores fusiform, verrucose, multiguttulate, hyaline, measured

Paraphyses cylindrical, mostly straight, septate, width 4.5-5.5um.
Medullary excipulum with 3 layers.

Growing on the ground. Very common right now.
Asci 8-spored, IKI+ [WT], croziers(+).
Ascospores biguttulate, verrucose.

Under big tooth poplar, white cedar, grey alder, red maple, American beech, smooth alder, and yellow birch and pussy willow - Salix discolor were 10 meters away. Constantly wet low area near a creak.
