Tremella foliacea

[SheffieldLass]

This one appears to be Tremella foliacea not an Exidia species that I found on New Years Day. The black appearance misled me.


I was expecting sausage shaped spores and got spherical ones instead!

9.3-11.1 x 7.3-8.9um, ratio 1.2-1.4

There were also these which I'm wondering if they are conidia. Does this species produce conidia? Or are they just remnants of gelatinised hyphae?
6.7-11.4 x 1.2-1.4um


Also a medallion clamp. I thought I'd post this as there are no google links to pictures of medallion clamps and nothing shown in any of my books.

Hi Melanie,

I think the conidia belong to fungi growing on your Tremella, but not to the Tremella itself. All these fungi with exposed hymenium often contain alien spores or hyphomycetes and such things on it. Friends of the Corticiaceae (yes, it is said even those have friends ...) can tell you stories about surching for the right spores between all the different spores in the preparation.

The medallion clamp looks strange to me. I think it is just a hyphal bow, not a clamp. I would except also to see more then just only this one in the preparation, but I can not see another in the picture.

best regards,
Andreas

Hi Andreas

There were a few medallion clamps, or things that I assume are medallion clamps (the only one I've seen a picture of is on an image in Bioimages, so I could have got the wrong thing!) but maybe only one or two in a view. The processing of the photo onto this forum has lost some of the detail. This was another one, again some detail lost, unfortunately.



Thanks for the info on the conidia. I notice that a lot of the fungi in this patch do get other things growing on them, which does muddy the water somewhat!

Oh and I meant to attach a picture of the hot cross bun basidia in the first post as they are quite fun ...

Hi Melanie,

yes, I suppose you are right, that these structures are indeed medallion-clamps.
