Hi.
Many times I found species from this kind but have usually missed conidiophores. This time, however, both forms occur at the same time almost in every sample collected so I think conidiophores belongs to this species.
I looked through all the available articles on Gibberella but nothing could match. Finally, I found a drawing of Gibberella intricans, Wollenweber, H.W. Fusaria Autographic Delineata, EDN 3: I, 660-1100: 810 (1930).
In principle, all features match my collection.
Initially measured the spores overripe, I did not fit their width. I found a less mature fruiter whose spores with sizes correspond to those from the engravings.
Relevant note is that the spores are in most 3-septata (rarely 5-septata).
Spores;
(27.7) 27.8 - 31.2 (31.5) × (5.3) 5.9 - 7.3 (7.5) µm
Q = (3.9) 3.94 - 5.27 (5.3) ;
Me = 29.1 × 6.6 µm ; Qe = 4.4
Conidia
31.3 - 37.2 × 4.6 - 4.89 (4.9) µm
Q = (6.8) 6.84 - 7.6 ;
Me = 33.7 × 4.7 µm ; Qe = 7.2
However, I am wondering a very poor reaction to KOH?
What is your opinion on it?
greetings

This is clearly a Fusarium ss. str.(syn.: Gibberella).
Compare with lignicolous species Fusarium lateritium Nees, ascospores as well as 3(5)-septate conidia seem to match.

Again, I had to look a bit of literature about it and compare my.
It seems to me that you are right. Features very good fit to the genre that you offered.
Thank you very much
Mirek
