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
