I notice that in my previous comment I put the thing in the wrong way, ending by writing the opposite of what I wanted. Fortunatelly, I gave a reference that says what Nathan mentioned.

It could be peniophora, quercina or other that I saw here http://www.naturespot.org.uk/species/stereum-rameale. As I didn’t pay attention till today to any peniophora, I trust on your “eyes” and opinions.

I just want to say

that 1º)stereum is much more common here than peniophora, that 2º) this is a dead oak, that 3ª)the limits of the dyed host seem rounded like some stereum that I commonly see on branches like this http://www.naturespot.org.uk/species/stereum-rameale and that grows on oaks, and that 4º) in third picture you can see something under tremella. Sorry,I didn’t want to influence you, but I couldn’t help saying this.

Looks like Peniophora…

The crust on the sticks does look a lot like some of what I could find on the web for Peniophora quercina (e.g., http://www.micologia.net/gallery2/main.php?g2_itemId=60586) and I don’t see any evidence of a Stereum, so I’m going with T. mesenterica.

Tremella as a parasite
By: Nathan Wilson (nathan)

I believe zaca has it the wrong way around. T. mesenterica parasitizes Peniophora, but has been widely publicized as being associated with Stereum (e.g., in Mushrooms Demystified), whereas T. aurantia is a better name for the common Stereum parasite. The discussion and citations for this are available on the MO name pages which you can get to by clicking on the names in this comment.

If I have this wrong based on some additional evidence, please update the MO name pages and provide references.


Yes, it’s on oak

could be Peniophora quercina if it’s on oak.

The purple crust …

in the photos can be an old specimen of Chondrostereum purpureum. I don’t know if they can serve as a host of any Tremella.

Zaca, please see the third photo

I think the host (dried) is there (nor sure) but I think I saw that in other twigs, but I don’t know the name, maybe stereum.

T. aurantia vs. T. mesenteria .

Tremella aurantia parasites Peniophora spp. while Tremella mesenteria parasites Stereum spp. . Unless you can identify the host, it is not possible to know which is it by using macroscopic characters. See California fungi.
