At the time I'm running the dichotomic key and comparing with growth characteristics in culture.
PDA (Potato Dextrose Agar) A.Av (oatmeal agar).
P1 = sporangia average 29,31μm long and 13,96μm wide
Oogonia between 9-13 μm in diameter
P2 = Sporangia 11 to 54μm long and 9 to 36 μm in width
chlamydospores around 9,5μm
oogonia average diameter 37,32μm
Hi Natalia
Apparently it lis actofenos blue dye. I recommend you take the photograph at higher magnification, and you show the structure , you want to identify
with an arrow. It will be more convenient.
Thank you Dr Beatriz elena Guerra, I will upload the photo with the arrow.
Mr. Shailendra Kumar, I will seek more in P. cinnamomi' structures.
Dear Natalia,
My first guess would be chlamydospores. However, for a more accurate tentative identification, you need to provide better pics, more info on culture conditions, host plant, disease symptoms, ..., etc.
Dear Natalia
I agree with Mohammed in my opinion these are chlamydospores.
Pablo
In the picture 2 I see one sporangia and a typical hypha swelling but I don't sure that is P. cinnamomi
Hi Natalia
I agree with Sonia that there are oospore like structures on the third photo. And I would assume too that there are two different organism on the other two photos.
Heiner
Hi Natalia,
I am agree with Dr. Mohamed and Dr. Pablo Enrique, these structures are chlamydospores.
Ricardo
Hi, Natalia
Round structures are effectively chlamydospores. Unable to determine the species with single images.
No germinating chlamydospores are observed, at least in the photographs provided. therefore "sporangia" can not see
