Lachnaceae?

Fruiting from a dead Quercus leaf from the forest ground, Pennsylvania USA. The largest apothecia after incubating the leaf for one day was about .5mm wide.  Hairs, asci, paraphyses are hyaline.  No reaction in KOH, ascus apical apparatus and ends of spores are slightly amyloid in IKI. Hairs have crustations/crystals. Ascus opening width is narrow. 
(8.4) 8.9 - 12.5 (14.1) × (1.5) 1.6 - 2.1 (2.2) µm
Q = (4.6) 4.9 - 6.3 (7.2) ; N = 20; Me = 10.5 × 1.9 µm ; Qe = 5.6
Hair measure:(56.6) 60 - 66.5 (68.7) × 3.5 - 4.8 (5.4) µm
Q = (11.8) 12.4 - 18 (18.3) ; N = 8; Me = 63.7 × 4.2 µm ; Qe = 15.7

Re : Lachnaceae?
I am not sure if you mixed something here.
There are almost cylnidrocal spores (living in water) and strongly fusiform ones (in ?CB).
Together with the large spore size I suspect the latter to be Incrucipulum ciliare. But there the hairs are thick-walled and bear crystals, and the living spores would be multiguttulate.

Please, if you have it still fresh, look again in water for the large fusiform spores.

Thanks for the quick response.  Attached are some more photos of the spores in H20.

Re : Lachnaceae?
So they are all eguttulate. What is the length of the scale in the spore photos?

Re : Lachnaceae?
Then you must divide your measurements /2. I measure 11-16  x1.8-2.2.

But I cannot recall s species like this, perhaps American.

Re : Lachnaceae?
Hans, you are right.  I measured from a 1000x photo while I was thinking it was 400x. 
The correct spore measurement is:(8.4) 8.9 - 12.5 (14.1) × (1.5) 1.6 - 2.1 (2.2) µm
Q = (4.6) 4.9 - 6.3 (7.2) ; N = 20; Me = 10.5 × 1.9 µm ; Qe = 5.6
Thank you for acute observation and sharing your expertise!
