Unknown Helotiales on Juniperus sabinae
DirkW, 20-03-2021 14:50
DirkWSalut a tous,

yesterday i found this little discomycete on leaves of Juniperus sabinae:
Apothezia: 0,3-0,8mm, fresh translucent to white, drying the hymenium becomes greyish to light brown, stalked up to to 0,5 mm, base is blackening (!).

Asci 40-50 x 6-8, J+ (blue), Croziers +. Spores 8-9 x 4, Oil 0-1.
Excipulum ends in little hairs up to 8-12, 1-septated, a little curved and apical swollen. they seem to be very fine warted, not totally smooth.

It reminds me at genus Cistella, but I'm not really convinced by this idea. Is there a species on Juniperus?

Who can help?

All best from Dirk
