Re : Salmon-pink Penicllium like species on Ficus carica stems
Hi,
I have worked further in this mould. The colonies grew as white cottony cushions, quite convex (raised) with the characteristic salmon-cream colour at the centre, almost same colour as the structures found in situ. Only on MEA there was rope-like morphology in the culture. The reverse is also ochre-salmon colour.
On rechecking the microcharacters, I've made an interesting observation - in cotton blue stain (but not in Congo Red) I could see the spore mass aggregated as a mass on the penicillum apparatus and hence I ask you if this is probably a Gliocladium sp. or even more probably a Paecilomyces sp.
Spores measured 4-5um, very abundant, variable in size (some almost 1.5x as long), bean-shaped or elliptic with granules in the cytoplasm.

Hi Stephen, did you consider Chlonostachys?

Re : Salmon-pink Penicllium like species on Ficus carica stems
Dear Christian, I did in fact considered Gloicladium sp. (such as G. roseum) although I was not aware that it became named as Clonostachys. Well, the fruiting bodies were not typical of Gliocladium s.l. = condensed in 'bulb-shaped' aggregate whereas my resulting colonies were a bit different from what I've seen on the net for this species (hopefully reliable):

I have also considered Paecilomyces which poduces cottony colonies like mine - look here:

from the article:
http://file.scirp.org/Html/4-2270245_40127.htm
but most of them produce conidia in chains so that's a mismatch (unless there are species which do not form chains).
SO I think this should between one of these two genera... I look more carefully another time

Re : Salmon-pink Penicllium like species on Ficus carica stems
I found what I was searching for - masses of spores on the penicilli-like apparatus which should lead to Gliocladium sp. I have never seen conidia in chains which are typical for Paecilomyces.
The rose colonies are typical to G. roseum = Chlonostachys roseum so I think this is so far the best identification to my colony.
Incidentally, I found a nice article with matching photos on this article titled:
Gliocladium Roseum: Rotten Grapes Fungus Produces Diesel
https://www.greenoptimistic.com/diesel-fungus-gliocladium-roseum-20081106/#.Wh09zUqnGM8
I don't if it is a characteristic but both my images and that of the web above show reddish blobs in the spores.
