Xylaria sicula ?

Dear friends. A common Xylaria here on the Maltes islands is that found on fallen olive leaves in humid and shaded areas. I took some specimens to educate and learn on this genus and following a key online: [http://pyrenomycetes.free.fr/xylariaceous/keydir/dichotomickey.htm]I did not went into much work, because xylaria on olive leaves is quickly keyed out as Xylaria sicula.
When I checked the details I found one mismatching character, apart that the spores were on the lower end of the range. X. sicula should have a swollen fertile head close to the apex which I colud not see in my specimens.
Any feedback?

Re : Xylaria sicula ?
Hi Stefen,
this is likely X. sicula but at conidial state. What you observed are conidiospores.
The sexual state will occur later and will be black, thus less conspicuous in the leaf litter.
Cheers,
Jacques

Re : Xylaria sicula ?
Thank you very much Jacques, I understand perfectly. I will check carefully the leaf litter for capitate apices.
