Hello.A tiny ascomycete found embedded in wood in a very advanced state of decomposition, appearing beneath some specimens of Hemitrichia clavata.
Spherical ascoma with a blackish, globose-angular wall, from which highly pigmented rhizomorphs with few septa sprout.
Octosporous asci with a small apical apparatus resembling two dots. Paraphyses very scarce to practically absent; the few observed are filiform and septate.
Cylindrical-ellipsoidal ascospores, completely filled with guttules, inamyloid, and with the following measurements in water:
(13.4) 13.7 - 16 (16.7) × (5.3) 5.5 - 6.4 (7) µm
Q = (1.9) 2.2 - 2.7 (3) ; N = 21
Me = 14.8 × 6.1 µm ; Qe = 2.4
I admit that I am completely lost this time.
Any opinions from you would be greatly appreciated.
Thank you very much in advance.
Best regards.
