Re : Lophodermium sur aiguilles de Pinus sylvestris
Je pensais à Lophodermium pinastri…
Quelqu'un peut-il confirmer/infirmer ?
Merci d'avance !

Re : Lophodermium sur aiguilles de Pinus sylvestris
Hi Bernard,
in my opinion is this Lophodermium pini- excelsae, good to see the fine stromatic lines. L. pinastri have many and strong stromatic lines and ripe reddish lips, L. p.- exc. the lips are greyish to light blue.
Of course the length of the asco spores must be considered.
Pictures of L. seditiosum, on pinus needles too, I enclose.
Greetings Peter.

Re : Lophodermium sur aiguilles de Pinus sylvestris
Hi Peter,
A big thank you for your informations and pictures !
I therefore eliminates Lophodermium pinastri and will look at this more closely tonight. So that will be played between Lophodermium pini-excelsae and Lophodermium seditiosum.
See you very soon,
Bernard

Re : Lophodermium sur aiguilles de Pinus sylvestris
Hi Peter,
I just checked several things :
a) transverse stromatic lines on the needles : black, present but rare
b) asci : 120-140x10-14
c) the length of the spores is approximately that of the length asci (once the spores are outside the ascus, they are very difficult to measure and start spiraling)
I think it's OK for Lophodermium pini-excelsae. What about you ?
Thanks in advance.

Re : Lophodermium sur aiguilles de Pinus sylvestris
Hi Bernard,
for L. pini- exc. the spores are to long (must be round 60 µm). The color of the lips ?
Probable however L. pinastri.

Re : Lophodermium sur aiguilles de Pinus sylvestris
Hi Peter,
The lips are not red but black. I know I saw one spore out of asci 85 mu long.
So, OK for Lophodermium pinastri.
Thank you !
