Botryosphaeria?
Ismael Wind, 25-03-2021 13:38
On populus i found these largespored ascos. I think it is  Botryosphaeria probarbly quercuum considering the size of the spores 32,5-37,5 × 12,5. Am i thinking in the right direction? Thanks

Re : Botryosphaeria?
Hola Ismael, la Botryosphaeria dothidea es muy abundante por mi zona, además de sobre Populus también la he encontrado incluso sobre Hedera helix, la morfología esporal y las medidas esporales parecen apuntar a ella, en uno de mis estudios las esporas midieron:´
(22.7) 25 - 32.9 (35.2) × (7.8) 8.3 - 10.4 (11.9) µm
Q = (2.1) 2.6 - 3.6 (4) ; N = 30
Me = 28.7 × 9.4 µm ; Qe = 3.1
Te adjunto tres imágenes mías de la Botryosphaeria dothidea, dos sobre Populus y una sobre Hedera.
Saludos cordiales.
