Hello i get this Mollisia i guess i hope somebody would help me i dont have enough literature to support my idea here i have some pictures Ascospores (7-) 8 - 11 x 3 um
asci (55-) 56 - 65 (-70) x 6 - 8 um
paraphysis filiform with 2 um broad.
apothecia discoid yellowish with black margen, superficial on wood.

Re : Mollisia ?
Hi
impossible with dead material, sorry. Where did you collect this, at a moist place? Which country? Is it some months ago? otherwise you could find living spores when mounted in water.
On your second pic you can see that the spores contain two big oil drops. Possibly they are confluent, but this is not very usual in Mollisia.

Re : Mollisia ?
With subtropical Mollisias I have hardly any experience. But it looks like one, yes.
I see the apical ring on your photo but not in blue. You could add KOH and afterwards (after a bit washing with water) add Melzer again. Then it should be clearly blue.
Or you can use Lugol directly (without KOH). The ring looks a bit reddish, maybe it is hemiamyloid.

Re : Mollisia ?
Hello Zotto thnks for your correct opinions
but now i have other problem with Mollisia
i checked othe apothecia from the same collection i founded microscopic structures with changes in size and form. check out th pictures.
Ascospores 12 - 16 x 5 with 3 septa
Asci (72-) 85 - 115 x 10 - 11, blue pore in Melzer ..
macroscopic is the same..
apothecia sessil with black margin, disc lemon- yellow growing up in wood.

Hi Yei
I see you live in an exotic world :-)
No idea, and surely not the same as before.

Re : Mollisia ?
Hello Zotto.. i was reading some Denni's literature and maybe the specie is Mollisia ventosa for variability in septation 1 to 3 and the size of spores and asci very long.. its similiar to Mollisia graminea too just differs in the long of spores..
well this is for the exotic fungi XD

Re : Mollisia ?
I am sure it is something else. M. ventosa I forms 1-septate spores when overmature. Yours looks more like a fungus that ejects 3-septate spores.
