Bionectriaceae on Ulex
Enrique Rubio, 15-02-2017 16:40
Enrique RubioHi again
These small ostiolate, KOH-negative, perithecia were clustered on a stroma erumpent from bark of Ulex. Over the perithecia are small amounts of white cottony conidiophores that perhaps belong to the asexual morph of the fungus (see photo 3). The ascospores are minutely verrucose.
Could this fungus Bionectria ochroleuca be?
Thanks again for your help

Re : Bionectriaceae on Ulex
Hi Enrique,
I agree with you, it is Bionectria ochroleuca with its clonostachys asexual morph.
This species is very common on Ulex.
Best regards,
Christian
