Hallo Markus

this is a Cordieritidaceae. Cordierites or something similar. If you apply KOH you should get a yellow or brown dissolution of the excipular pigment.

It is surely worth to make a section of the excipulu at flanks. is the exterior made up of pyramidal tufts making a rough surface?

Zotto

I am quite sure that also "Cordierites cf., X.2012-2" by Esquivel grew upside down, it was photographed this way (see Ascofrance): http://www.ascofrance.com/search_forum/20066

Thank you, Zotto!

i made a picture of the outside, i'ts a lot of globose cells. I'm think these species are very special form with the clearly stipe and the not closed aphothezium like a Spoon.

I'm wondering, whats name whe can give.....

To later, Markus

So the excipulum is hyaline?  Anything brown or yellow more inside? Important is the ionomidotic reaction in order to try a key.

Zotto

i made new pictures from the Exsikkata. In water and melzers.

The exipulum it's sligthly brown and sligthly dextrinoid in melzers.

I hope, the pictures shows that'

Markus

I would not say dextrinoid, if you mean the stain of the cell plasma. But what many Cordieritidaceae have is the ionomidotic reaction: Put a fragment of the fungus in a drop of 2-10% KOH and veiw if the sap gets yellow or brown. Also under the mic. this can be tested by adding KOH to the water mount. The "reaction" (dissolution) must be viewed a few seconds after KOH comes in contact.

dear Zotto,

i made these reaktion and all to stayin the same colour. When you interesting, i can send you a Exsikkata? I have the adress in Tübingen.

Markus

 

Also die Farbe der Fk. ändert sich nicht in KOH und es tritt auch nichts aus?
ich würde gerne Kadri fragen ob sie den Fund untersuchen und DNA gewinnen will.

Hello, Markus Wilhelm!
That is very interesting collection and I would like to have possibility to study it. If you like to share e.g. one fruitbody, this found will be included to our lab Cordieritidaceae molecular analyses. Tropical species are purely represented there yet, and Cordierites-like taxa especially. We would be very thankful, if you can send a piece of collection to:

Hello Kadri Pärtel,

i have enought material, i can send you e entire Fruitbody. In the Rainforest wait a lot of unknown species to research. In Marasmius a endless quandity.....

Thanks for help, auch dir Zotto vielen Dank! Markus
