Dichomera on Rhamnus frangula
Bernard Declercq, 10-04-2017 17:12
Bernard DeclercqHi to all,

Collected last week on bark of Rhamnus frangula in Belgium:
Conidiomata stromatic, erumpent, multilocular, 1-2 mm diam., frequently confluent, blackish brown. Conidia muriform, globose, subglose to broadly clavate, some with a truncate basal end, 10.5-12.5x7-9.5 µm, with 1-2 transverse septa and mostly with one or two longitudinal or oblique septa. Conidiogenous cell cylindical, a.o. 13x2-3 µm, hyaline.
This is most probably Dichomera saubinetii (Mont.) Cooke ss. Sutton.
Does this species have, Dichomera being a synonym, an actualised Botryosphaeria name?
Thanks for your help.

Bernard
