Lachnaceae? on dead wood
Marcus Yeo, 11-12-2013 21:49

This discomycete was growing on fallen twigs (of Quercus or Fagus) in litter in lowland woodland. Details as follows:


Apothecia: creamy white, short-stalked, <1.5 mm diameter, hairy on outer surface and stalks.


Excipulum: textura prismatica.


Asci: 55-65 x 5-6 µm, arising from croziers, apices blue in IKI.


Spores: (8-)9-11(-12) x 2-2.5 µm, with a few small oil bodies at each end.


Paraphyses: broadly lanceolate, multi-septate, no VBs, 60-70 x 5-7 µm, exceeding asci by 5-10 µm.


Hairs: 45-60 x 3-5 µm, hyaline, septate, tapering to apex, smooth, sometimes with oil drops adhering to walls.


I assume it belongs to the Lachnaceae but I'm struggling to put a name to it. I'd be grateful for any help.


Many thanks


Marcus

Mi Marcus

exquisite!! 
Colipila masduguana. Do you have my paper on this?
Colipila, a new genus in the HelotialesHans-Otto Baral & Guy Garcia & Mesfin Bogale &Matthew J. O'Hara & Wendy A. Untereiner, in Mycological Progress 2012

Please lok whether the pores of the wood are large (Quercus, ring-pored) or small (Fagus). Usually it was on Castanea or Quercus. Only known from France so far.

Zotto

Many thanks as ever for your invaluable help! I've just had a look at your images of Colipila masduguana and my specimen certainly has the same distinctive features as your collections.

I don't have your paper in Mycological Progress.

I'll check the substrate to see what species it is.

Re : Lachnaceae? on dead wood
I'm just looking at the specimen Marcus kindly sent us at Kew. Not as nice as the fresh material but still quite recognizable! Zotto, please could you send me a pdf of your paper about Colipila in Mycological Progress?

Much appreciated
Paul
