Encoelioid on Punica granatum
Nihad Omerovic, 21-05-2024 11:33
Hello,

found on dead, dry, attached (and fallen) twigs of P. granatum, at the end of April.

Spores measurements:

(13.9) 15.8 -17- 18.8 (20.5) × (3.6) 4.2 -4.6- 5.1 (5.2) µm
Q = (3.1) 3.4 -3.7- 4.1 (4.4) ; N = 31

Asci: 147 - 153 µm, IKI negative

Hello,

See Rutstroemia punicae.

Re : Encoelioid on Punica granatum
Thank you, Andgelo

yes, I suspected it too, and I already compared it to that species, very similar. One clear difference is IKI reaction - this one is negative. Still not sure...

Re : Encoelioid on Punica granatum
This is a great collection! You should look for the excipulum and crystals.

It must be Rutstroemia punicae, known only from the type collection.

Are you sure the IKI reaction is negative? Your photo is unclear herein. Good would be to test dead, somewhat immature asci.

Re : Encoelioid on Punica granatum
New attempt
Very faint reaction and very few asci but it's there

Re : Encoelioid on Punica granatum
what are these deposits?

Crystals?

Re : Encoelioid on Punica granatum
The reaction is quite distinct, medium deep.

Crystals are unknown to me in the type collection, but here it seems they are oxalate crystals.

What we need now is the ectal excipulum, I can hardly see it on your survey pic.

T. prismatica with long cells as in the type, or else?

Re : Encoelioid on Punica granatum
I had difficulties to obtain the reaction, I guess my lugol is going bad.

Textura should be "prismatica-porecta" ectal, intricata medulary, which I think it is, but don't have a good picture right now (squishy specimen); I'll try to confirm it in a few days.
