that’s the only real way to tell what you have here.
Very interesting mycoparasite.
Yes, you are right, the genus Syzygospora has more than one species (sixteen are listed on Index Fungorum), and these do indeed look like jellies. I assume the texture was jelly like when you handled them. As you noticed, it is hard to find descriptions of other members of this genus, though.
These remind me a bit of Arrhenia auriscalpium with those gelatinous but still gilled forms, although I don’t know of fungal parasites in this group.
I’m bettin’ this is a basidio…
