I haven't heard that term for it before Chris, wonder how it came about?
I think the tell tale black ova are visible on the lower left of the jelly.
Hi Cathal, I got it from this link
I think this is the frog version.

I finally got around to checking out your link. Thanks for that. It looks just as the frog version I am familiar with does, but do you know if the toad version is distinguishable? There are no toads over here so I wouldn't have seen it.
Sorry Cathal I have no idea at all, though I have never heard mention of toads in any debate on the matter. Chris
I know they dont seem to get the 'blame' much, other than being included alongside 'frog' in some IDs of this jelly on iSpot, but as they are anatomically similar could they not also produce a similar phenomenon?
I dont even know what toad spawn looks like to be honest, must google it.
It is in long strings
Toads secrete toxic chemicals, frogs do not.

Rumoured to occur after meteor storms I believe
My understanding is that samples of "star jelly" (aka various other names) have been shown not to contain any DNA. Surely if they were from a frog - or any other animal - there would be some detectable DNA, especially if, as is often suggested, there are remnants of spawn visible in the jelly?
To the lower left of the main body of jelly is the mass of black ova I refer to. It is showing some signs of decay as it is beginning to go white as it does the longer it is exposed to the elements. When freshly exposed it is jet black.
http://www.examiner.com/article/star-jelly-space-goo-appearing-edinburgh.... at the end is an "expert" informing us that not finding DNA in undeveloped frog spawn is quite normal
Not finding DNA in the jelly I can understand but when one is trying to identify the stuff surely tests would have been done on the supposed black ova which I assume must contain DNA. Do we know if anyone has done this - critical - test?
Sorry for all the links but if you scroll down to last picture on this page there is a Myxo that looks very similar. Clear jelly changing to black ball shape. I have tried to find what species from the list but its time consuming.
I think that is in fact black frog ova and entrail, dried out a bit but frog(toad or newt perhaps) ova and not mould.
A fresh version of the same thing, undried, is here:-
Edit- Mark sorry for linking this twice in responses to yourself. I hadnt seen this comment of yours pointing towards the pic at the bottom of the linked page when I made my former post with link! This ob. is getting more and more interesting all the time!! If a bit complex....
Hi Mark, a debate that will no doubt rumble on and on, I think. My only question is that this substance appears to be in standing water, would a slime mould form in such a place, I don't know the answer by the way. Chris.
What is that black stuff at the bottom of the linked page;
The last photo? It isnt titled but it looks extremely like a dried version of discarded frog remains as in my observation here:
I just cant see what they are saying it is on that page, maybe you can help???? Cheers,
I think this may be the authors error at including as I have looked through every one on that list and it is not named at all.
Could quite easily become inundated as not the fastest movers lol.
I hadnt heard about star jelly before yesterday but I am familair with predated frog remains and the jelly and ova present along side pieces of frog and frog entrails look exactly like the picture above. Clearish acqueous matter and clumps of black beads stuck together which are exactly the same size and colour as frog ova. Finding it beside frog remains in frog habitat during the Spring would lead me to believe that it is unspawned frog spawn which has been exposed to the elements prematurely as a result of the animal being torn open by a predator rather than by the frog spawning it.
Edit- this is my best guess for the dismembered frogs I see at moorland lakes in the Spring and the associated lumps of jelly with black beads. Why the predator doesnt eat the frog intact I do not know. Herons seem to shoulder a lot of the blame, they are very obvious at the lakes in the Spring months but otters and foxes are present also.
Plenty of theories exist about this stuff. Have a look at http://www.bbc.co.uk/scotland/outdoors/articles/jelly/ if you have a spare hour or two!
As I've suggested above it really doesn't sound like rocket science for someone to have a proper look for DNA which might settle things one way or the other.
Its been done and there was no DNA in it.
University of Edinburgh and Biodiversity Observatory (OU)
So we're saying that we've got unfertilised ova with no DNA?? How can that be?
Nope. Not ova. Its the jelly. That is not cellular, but the product of cells. The comparison with snot is quite apposite.
See this http://www.ispot.org.uk/node/101544?nav=news_stories
That seems fairly conclusive and I'd not seen it before.
Another example of the black ova in the picture above which explains where the jelly originates from can be seen here:
On this occasion the jelly wasn't present, but the commonly refused part of the frog which explains the occurance of the jelly is present.
I have moved this to the Amphibian group for you.
This is fascinating! frogs, herons and foxes all present at the reserve so makes sense, thank you for everyones comments, ideas and discussions...
The Jelly was spotted first and 60 yards away I found the Frog near one of our ponds either it was discarded or I disturbed a predator.
