Dothideales on Rhytisma andromeda
Nina Filippova, 31-01-2015 08:15
Good time to everyone. There is an under-identified Dothideaceous species which was noticed on Rhytisma andromeda stromas. I am not sure if it is parasitic, as the stromas at the time of observation were already dead, but the leaves were attached to the plant. It was fairy common at that time on Andromeda polifolia.

Probably this species could be interesting from the view of bio-control of tar spot disease.

On attached dead leaves of A. polifolia affected by Rhytisma andromeda at first, 29.7.13, near Khanty-Mansiysk, Russia.

Ascocarps immersed in Rhytisma's stroma, appearing at the surface as irregular warts with orangish punctation, globose, up to 100 mk in diameter, pore more or less pronounced; walls of layers of brown irregular cells; asci about 40 x 10 mk; paraphysoid tissue not developed; spores fusoid, hyaline, two-celled, slightly heteropolar, with deep constriction, some broken in two parts, about 15–17 x 2.5–4 (n=5).
