Volutella?

Josep TorresHello.
Some very tiny conidiomes collected in the Dominican Republic, at sea level, appearing on a leaf in an advanced state of decomposition of Coccoloba uvifera.
Disc-shaped conidiomes with marginal hairs, pure white in color, with a diameter excluding the hairs of between 0.3 and 0.7 mm.
Thick-walled marginal hairs with pointed ends and abundant crystallizations on their surface.
Conidiogenous hyphae that appear to arise from a common point with a radial arrangement, producing in chains fairly uniform, cylindrical conidia with a faint granular content inside and measurements of:
(12.1) 12.3 - 14.2 (15.1) × (2.1) 2.3 - 2.57 (2.6) µm
Q = (4.7) 4.9 - 6.1 (6.6) ; N = 20
Me = 13.4 × 2.4 µm; Qe = 5.6
The closest match I know would be Volutella or related genera, although I'm certain it's not Volutella ciliata.
Any opinions you may have would be greatly appreciated.

Thank you in advance.
Best regards.
