More Blobs

Every so often I find a strange blob of something growing in the woods. Trying to identify what they are is often challenging - it's hard to tell if they are fungi or slime moulds or something else entirely (eg. star slime from gutted toads.)

 But this week, with the aid of a slightly more comprehensive field guide, I resolved two of my longest standing mystery blobs:

Tremella steidleri
Blob 1 was an impressive gelatinous lump I found growing on the side of a mossy oak in 2007. Revisiting the site last week, I found a smaller but similar blob. It was right next to some Stereum hirsutum brackets, and looking through Tremella again I found this species which has a distinctive, knotty form, and a distinctive, frosty bloom. The way the ageing fruiting body disintegrates into slime might also be distinctive enough to aid in identifying similar blobs.

Postia ptychogaster - fresh specimen

Blobs 2 & 3: One from 2010 and one from 2016, I couldn't figure these out until I was looking up a very ordinary bracket fungus from the genus Postia  and saw an illustration of Postia ptychogaster on the same page.

Yellow Brain Fungus

Tremella mesenterica - yellow brain fungus
I see this a lot - it's very common on gorse bushes in Argyll, and fruits throughout the year.

The Blob

Monday Mushroom #92

I found this big glob of translucent slime on a rotting log in december. At first I wasn't sure what it was but the presence of hairy stereum - Stereum hirsutum - fungus on the same log was a clue.



Tremella - a genus of jelly fungi - are all parasitic on various crust fungi. The most commonly seen is Tremella mesenterica the yellow brain fungus, but three related fungi Tremella aurantia and Tremella foliacea parasitise Stereum Spp.

I've photographed them before, so here they are:

Tremella foliacea

Tremella aurantia
Tremella steidleri

I'm guessing my blob was probably a very old, decomposing Tremella steidleri...

Tremella foliacea

Monday Mushroom #7

Leafy Jelly Fungus - Tremella foliacea
It took me a while to identify this fungus as it was not included in any of my field guides. Given that it is quite large and distinctive, that suggests that it might be quite uncommon in Britain.
