| | | Ascomycete on dead birch (wood)
Hello All
Today I joined a foray at Bole Hill Quarry with the Sorby National History Society (Sheffield)
On dead Birch (wood) I found this quite distinctive Ascomycete, possibly a Mollisia but not sure. Typical size approx 1mm dia. 
Any help / comments as ever much appreciated

Hi John
There are quite a few grey/black disco's and that tend to look much the same macroscopically. I think you will need to use the microscope on this one

Hi John,
what about the orange growths too - any idea what they are?  
Cheers
Ken

Peter | Thanks Peter. I was just trying to cut down on the number for microscopy ... or at least narrow them down a bit  Quote:

I can see that some of these black discs look more orange than others - is it these orangey ones that the Calocera emerge from ? And does this rare form have a name John ?

Hi John,
Might be leading you on a wild goose chase here, but there are several of the Orbilia species of the sub-genus Lenta which look very similar (macroscopically) at certain stages of their fruiting cycle to your find.
eg. O.purschiana, O.atrolenta, O. tenuissima, O. patellarioides.
See: - Orbilia subgenus Hemiorbilia sectio resinicola
Unfortunately those specific ones don't seem to be recorded on the FRDBI.
But - as they tend to look different (colouration etc.) when less "mature", perhaps what you've got is one of the recorded British Orbilia species but just in very mature condition? (Could also be reason for difficulty in finding spores?).
Regards,
Mike.

The Birch had much of this plus Orbilia delicatula. It also had Mollisia growing on it, in fact I found 8 species of fungi growing on it without searching too hard!
I've got several 'bits' at home which I'm keeping an eye on ... and a few dried apothica for Kew ... just in case
