Ombrophila on Pinus cone
Juuso Äikäs, 31-10-2022 08:26
Last week I found a few grayish white to vinaceous Ombrophila fruitbodies in a rock outcrop. They were growing on a fallen Pinus sylvestris cone that was buried inside moss.

The asci are 8-spored, with croziers, with a rather faint blue IKI reaction. Paraphyses cylindrical, with a mollisioid VB; similar cells on the margin as well. Medulla gelatinized, without crystals.

Spore measurements:

(6.6) 7.2 - 8.4 (8.6) × (2.9) 2.95 - 3.4 (3.7) µm
Q = (1.9) 2.1 - 2.7 (2.9) ; N = 15
Me = 7.8 × 3.1 µm ; Qe = 2.5

My best guess is O. rubicunda, but am not sure at all.

Re : Ombrophila on Pinus cone
I think this fits quite well. I remember a not very gelatinous medulla but mybe this varies.

I think this is not often found. I hope you will keep it, maybe sometimes someone wants to take a sequence.

Re : Ombrophila on Pinus cone
Ok nice, thank you. I made one preparation in Congo red, and I think the medulla might've been "tighter" and made of thicker hyphae there.

I still have the dry cone, but when I looked at it, the apos seem to have pretty much disappeared. Maybe I'll try to moisten it and cut the scales with the apos off if (or hopefully when) they reappear.

Re : Ombrophila on Pinus cone
yes, this is normal, that Ombrophilas shrink away :)

Re : Ombrophila on Pinus cone
This one seems to be a common species in Finland as I found it on my first attemt to find it, also on a rock outcrop. However, on the same Pinus cone there were also an anamorph, which I suppose belongs to the same species. It seems to be just a mass of small slightly allantoid conidia.

Re : Ombrophila on Pinus cone
Here you need to study the conidiophores. It looks to me like Ascocoryne dubia.
