Troublesome operculate... (lots of pictures)
Martin Bemmann, 09-08-2009 21:43
Martin BemmannDear all,

today I found these little milk-coffee coloured lads and I can't figure out their name (Rumpelstiltskin...?).
Ok, habitat is sessile on dead trunk (ca. 15 cm diameter) of Alnus fallen over a small creek (on loose bark). It was inhabitated by Orbiliae and Scutellinias as well.
Shape is a nearly round cushion.
Size of apothecia is 3-6 mm.
Asci are operculate and to my opinion IKI-, their size is ca. 345x15-17 µm.
The slightly clavate paraphyses are up to 35 µm longer.
The spores measure (19,8)20,2-20,9(21,3)x11,5-12,1 µm.
The textura of the excipulum is globulose and very hyaline.

I checked again and again my (limited) collection of books, tried to follow keys (Dennis etc.) without result.
I would very much appreciate any hint to find the genus at the least.

Best regards,

Martin

Hallo Martin,

hab grad keine Literatur zur Hand, aber makroskopisch sieht das sehr nach Pachyella babingtonii aus. Spricht da mikroskopisch was dagegen?

beste Grüße,
Andreas

Hello Andreas,

according to B&K Pachyella b. (I had this on my list but...) is IKI+ (however, "faible" as said in my french copy of B&K). The ascocarpes displayed in this publication are seemingly not very fresh as well.
But the pictures at Mycokey are very convincing!

Thank you Andreas!

Cheers, Martin

Re:Troublesome operculate... (lots of pictures)
Hallo Martin,

ich habe Pachyella babingtonii schon öfters völlig J- gehabt. Auch wenn sie positiv reagiert ist das nur ein diffuses blau der ganzen Asuswand entlang und nicht wie bei Peziza auf die Spitze beschränkt und deutlich.

beste Grüße,
Andreas

Re:Troublesome operculate... (lots of pictures)
Hallo Andreas,

ich habe inzwischen die Beschreibung von Dennis gelesen, das paßt perfekt!
Bei so schwachen IkI-Reaktionen bin ich mir immer unsicher, ob ich nicht nur durch die Optik hervorgerufene Farbsäume sehe.

Herzlich,

Martin

Hallo Martin und Andreas

man sieht daraus, dass es nicht reicht, nur J+ und J- zu schreiben, das führt immer wieder zu Konfusionen.

one learns od this that it is not sufficient to write merely I+ or I-, that leads again and again to confusions.

I will now be away for about 5 days, French alps with Guy and Bin Liu.

Cheers
Zotto
