Inoperculate from Borneo

Hello,these fungi grew in a large group in a primary rainforest in East Kalimantan, in litter, some fruitbodies grew on a fruit of a tree.
Disc measured 6-13 mm in diameter, was grey, somewhat frosty, slightly convex, sometimes deepen in the middle, sometimes saddle-shaped, smooth, often waved in older fruitbodies.
Lower side brown, slightly wrinkled or smooth.
Stipe was of the same colour as the lower side, narrowing toward the base, little bit wrinkled in the upper part, 19-55 mm long, 0,5-3 mm broad. The stipes were sometimes growing together.
Asci inoperculate, cylindrical, with amyloid inner ring, octosporic, with uni- to biseriate arranged spores, 85-110 x 4,5-6 micrometers.
Spores 8-10 x 3,5-4,2 micrometers, ellipsoid-ovoid, hyaline, smooth, without septa.
Paraphyses filiform, hyaline, straight or slightly bent, 1 micrometer broad, septate.
Rough brown hairs on the outer surface.
Excipulum of textura porrecta (?).
Some Rutstroemiaceae or Sclerotiniaceae?

Re : Inoperculate from Borneo
Looks very interesting. I first supposed it is more a Helotiaceae. The apical ring should be seen in higher magnification. But you may be right: the ring shows an inner protrusion like two dots, unlike Hymenoscyphus. And the warted hairs fit also Rutstroemiaceae better.
The excipulum would be important to see, perhaps in a section. Anyway this will be difficult to identify.

Re : Inoperculate from Borneo
Hmm, thank you, Zotto.
I probably cannot do more with this mushroom than I have already done... would someone be as kind to look at it? The collection is rich, including both young and old fruitbodies.
