This specimen was collected in the sand dunes close to the sea on an old piece of juniperus wood lying in the sand mixed with other wood pieces and pieces of Arundo. As can be seen in the photo it was overmature and the perithecia were exposed and britle, making impossible to have a good section. In addition, the hymenium had a dense gel layer making the microscopic observation very difficult. Only some free spores could be focused and to observe some asci I had to add a drop of chloral hidrate first and after some IKI (reaction negative). The spores are submuriform to muriform, first the hyaline, then pale brown and finally brown, with the following dimensions:
(16.2) 17.3 - 21.9 (22.4) × (7.3) 7.32 - 8.6 (9.1) µm
Q = (2.1) 2.2 - 2.8 (3.1) ; N = 32
Me = 19.2 × 7.9 µm ; Qe = 2.4
Any hint about it will be appreciated.
Thanks in advance,
