Unusual brown asco
Edit Szilvásy, 16-06-2014 09:20
Edit SzilvásyHi to all,
I found yesterday this species on a wet piece of wood in the wetland area.  Size 0,5-2 mm diameters.

Spores 12-13 x 2-3 hyalin, smooth. Not blue reaction with KOH.


Any suggestion?

Re : Unusual brown asco
Do you mean in iodine?

There is a Ionomidotis with such colour and spores but your spore size is too large and iodine reaction should be negative.

Re : Unusual brown asco
Dear Zotto,
Thank you for your attention.

I got a friend a Lugol (KOH) for identification . I do not understand why  seem to be smaller spores than in water.
I wanted to write  iodine reaction is negativ, (I know little English).

Re : Unusual brown asco
Lugol is = IKI. If you have KOH (potassium hydroxide) or NaOH the you can test whether the ochraceous pigment turns out in the medium. My idea is perhaps wrong, but worth a test.

Dear Zotto,

Thank you for your suggestions and help. I'm really sorry, but I don't have the recommended reagents, such as the fungus is not able to present to me.

Re : Unusual brown asco
To find a genus we need especially the excipulum, is it of globose cells or elongate, brown or hyaline. Also what paraphyses are between the asci?

Re : Unusual brown asco
Dear Zotto,
Thank you very much for your advice. Unfortunately, now I don't find more fruiting bodies.  I wetted the piece of wood, and I hope, that I can find for the identification paraphyses , asci, etc.
