Dear Forum,On decorticated wood of Castanea,I foun
Apothecia 4-7 mm. dark brown hymenium; subconcolor outer face with darker furfuraciones, which darkens as it ripens. white flesh that secretes increased serous latex white, unchangeable color.
Excípulo ectal globular texture. Excípulo medular inferior intricately-globular texture. Excípulo medular superior pigmented intricate texture.
Paraphyses capitate covered brownish mucus.
ASCAs cylindrical, hemiamiloydes (IKI).
(96.1) 98.5 - 110.3 (113.5) x (6) 6.1 - 6.8 (6.9) µm
Me = 105.3 x 6.4 µm ;
Spores with truncated warts 1-1.2 microns in height.
ESPORAS X 1000 AGUA
(10.9) 11.2 - 12.2 (12.7) x (10.3) 11 - 12 (12.3) µm
Q = 1 (1.1) ; N = 47
Me = 11.7 x 11.5 µm ; Qe = 1
What do you think?
Regards.
The ornaments of the spores look truncated, which would fit fine with Plicaria trachycarpa. The size of spores fits well also, and the ecology as well (burnt places).

Do you think of the presence of white latex immutable. It is also characteristic of this species?
Another question is about the proper naming of layers excípulo . I can discern three layers : an outer layer of pigmented somewhat globular texture , a middle layer of mixed texture intricanda - globular , pigmented top layer and intricate texture. Could you talk ectal excípulo lower , middle and upper ? Or of excípulo ectal - excípulo medular medio- excípulo medular superior?
Re: latex. There's nothing about it in the reference I own, but all the other features of your sample match with the description.
Cheers - LUC.
