| |  black mines!
Hi ,
grateful for help with these too from todays wanderings before it got too wet..............
On rotten deciduous log, in profusion, I've seen this before, commonly I think, but only now taken a piece for closeup shot, its very tiny, much less than a pinhead - it looks like black anchored harbour mines you see in films, with lots of antennae, but none blew up when I handled it!   
Cheers
Ken

A Powdery Mildew, Phyllactinia guttata, looks very similar to this, but occurs on the underside of Hazel leaves. This also has 'antennae' so perhaps you have a type of mildew ?

Possibly Lasioshpaeria?

Macroscopically, there is a fungus named Chaetosphaeria ellisii (syn. Lasiosphaeria ellesii), which has a stage looking very similar to these.

Regards,
Mike. | sadly that's not British . . . . there are 11 species of Chaetosphaeria that are though . . . . . if it did have projections then Lasiosphaeria is a possibility
in my experience Melanomma pulvis-pyrius is the commonest of these small gregarious pyreno's on decorticated wood
I suspect that I know the answer to this - did you collect any? Without a microscope you can't hope to get anywhere with these fellows I'm afraid . . . . Quote:

Neil. | powdery mildews are strictly parasitic - they don't occur on dead wood
cheers

Thanks everyone, thats a good start.............
Chris I do have it - and I have a microscope now, but need to get used to it - my last attempts at microscopy were in 6th form biology, some time ago - however, if you can let me know what I'm looking for, I'll give it a whirl.
Dont expect pics though, ha ha.
Cheers
Ken

Oops, I should have known that (and the 'antennae' are totally different as well)

What about the Pyreno Acanthonitschkea tristis - this was found recently and looks close, any further thoughts please?
Cheers
Ken

Ken | can you describe the spores please Ken?
single-celled/septate?
hyaline/coloured ?
size?
a drawing might help, if you haven't got a camera attachment yet
cheers
Chris
