Dear Forum,On decorticated wood of Castanea,I foun
Hi,I found this on dead stems of Vaccinium myrtillus.
Stromata: 0,4 – 0,6 mm
Asci: 200 – 275 x 12 – 15 µm
Spores: 20 – 29 x 8 – 10 µm
I come to Pleospora spartii but is this species not restricted to branches of Cytisus scoparius and if so, what could this be?
Regards,
Piet
Hi Piet,
( et salut Alain !)
Could you show us vertical secrtion of ascomata ?
Alain
could you send me as much as possible of your material?
Thanks, Walter
Dear Alain (Gardiennet): Can you tell me how an amateur as I can make a good coupe? What is the good method?
Dear Walter, I do what I can.
Piet
Hi Piet,
To make a vertical section, take a new razor blade, and cut in the median plan. It's not always easy and needs some experience, but it's often necessary, like with Cucubitaria species in which we have to observe ascomata shape and peridium structure.
Let's a big part of your material to Walter, it will be in very good hands.
Alain.
