Dear friends, I need your opinion on this crust Polypore I found on the wet bark of Ceratonia siliqua.
It is a white polypore which seems to be accompanied by its amorphous stage as grayish - olive green colonies at the perimeter of the crust. I include several photos of the teleomorph and anamorph, both macro and micro.
NaOH gave a green color change on the hymenium.
Spores bean-shaped, about 5um long
Measurements:
Basidiospores
(3.9) 4.2 - 5.5 (5.8) × 2.2 - 2.7 (3) µm
Q = (1.6) 1.8 - 2.1 (2.2) ; N = 18
V = (10) 11 - 22 (23) µm3
Me = 4.9 × 2.5 µm; Qe = 2 ; Ve = 16 µm3
Cystidia/Basidioles - 12.0-17.0um x 4.0-5.5um
Ascospores:
(12.7) 13.9 - 17.2 (18.6) x (9.1) 9.3- 12 (15.1) µm
Q = (1.1) 1.3 - 1.7 (1.9) ; N = 42
V = (546) 680 - 1210 (1985) µm3
Me = 15.7 × 10.4 µm; Qe = 1.5 ; Ve = 910 µm3
Basidia
19.10 x 5.4um (Sterigma = 2um)
20.5 x 5.7 (Sterigma = 3um)
I always have problems with crust polypores but Ropia and Ceriporia crossed my mind.
