Trichium?

Hi,
This yellow myxo was on very rotted pine. I only found the spores - no capillitium or fruiting bodies. The spores look interesting but I can't find a good match in my small Myxo book. Is this a Trichium?

Hi Steve

Looks like it could be a Trichia. However, you usually find lots of capillitium lying around.

Those spores do look quite odd - worth saving. Some capillitium would be useful for ID.

Cheers,

John

Thanks v. much John. I'll have another search for the capillitium :roll:

The colour is right for a Trichia spores. It could be pollen though - the ornamentation is very big and spiky for a myxo.

It wouldn't be the first time I have been fooled. I once tried to identify some dried white paint which was doing a very good impression of a resupinate :lol:

Kind regards,

John

Hi John,
Here's another what I'm more certain is a Myxo - on a pile of woodchips at our allotments - I didn't need to go to Specsavers to spot it! I reckon people passing by thought it actually was dog's vomit, as it was untouched. Looking at Google Images for "slime molds on woodchip" gave quite a few very close to this one - they were named as Fuligo septica, which I thought was normally bright yellow. It was quite hard and very dry, with amorphous matter and what look like spores at varying stages of maturity.
Cheers,
Steve

Hi Steve

Yes, it looks likely to be Fuligo septica. The yellow colour can fade with time. Some authors split the species into several varieties - var flava, candida, rosea and rufa depending on colour and other subtle differences.

Cheers,

John
