I don't have definitive answers as to what this glob is. It was picked up by one of my patrollers, initially arranged as if they were packed like orange segments, but they glided apart when she handled them. They were in a mucous sac, and definitely look like eggs or seeds (passionfruit likeness).
Most suggestions online think it's possibly frog eggs, not toads, since they present in a long strand. Another suggestion has been salamander eggs, which also seems likely to me since they come in a mass similar to this.
I wonder if they could be snails? Or could they be plant seeds? I can't imagine they'd need to be in a jelly, though. They separated out into individual blobs when I collected them.
I think this is blunt spikerush, (also called a spikesedge) Eleocharis obtusa, an American native. It's an annual with erect, cylindrical stems. Quite lovely!
When I found this strangely shaped dark 'pod' floating near the surface, I thought of a vanilla bean pod - it looked exactly like a seed case, with one end tapered as if it had been attached to a plant by a petiole.
Of course, I had to get a closer look, and that's how I noticed the segments on the 'pod' and checked a little further ... to discover that this is the larval stage of a black soldier fly (Stratiomidae), and that the 'petiole' is actually an elongated segment used as a breathing siphon in aquatic species.
I came across 17 of these flower floats still under water on my paddle this week - the invasive Utricularia inflata (swollen bladderwort) blooms again! This particular secluded spot seems ideal for them - most had their flowers submerged, but others had rafts and flowers on the surface.
As I sat still in my kayak, more and more became apparent to me ... how many do you see in this picture?
This post is about me exposing myself as a supreme plant nerd, if you weren't already aware of that aspect of my being! My Mum would have chastised me for blowing my own trumpet, but here goes anyway ...
I've been finding some unusual growth forms/structures on bladderworts in my lake on and off since 2022, and hadn't been able to find an expert who was aware of exactly what they were.
These structures that have my head whirling are the flimsy white filaments floating off to the side of the leaves in this next pic (Utricularia macrorhiza, or common bladderwort). They're not roots, which was my initial impression - this is a rootless, free floating plant!

These outgrowths are fascinating, yet no one else in my realm of lake experience had seen them before.

Filamentous shoots on Utricularia inflata |
I wrote an exploratory field note about the filaments I observed in Utricularia inflata (swollen bladderwort) in the Maine Natural History Observer (Tuberous Structures in Utricularia Inflata page 44) last year, but it was only this month, with the help of Laurie Callahan of the York County Invasive Aquatic Species Project (YCIASP), that my more recent query about these structures in Utricularia macrorhiza landed in the hands of Dr. Garrett Crow, one of the co-authors of our aquatic 'bible.' Lo and behold, traction at last!
He not only informed me that they were most likely air shoots, but he also wrote ... wait for it ... "Thank you, thank you, thank you Debbie. These are wonderful. You are expanding my understanding of Utricularia!! He thanked me for teaching him about bladderworts! What? Moi? Very, very gratifying (and terribly exciting) that he will be including my new information in volume 6 of the updated "Flora of North America." Is that a thrill or what????
Since then, I've been encouraged enough to spend hours and days, poring over the tips of air shoots for the best possible perspective. For the ultimate understanding. For the thrill of the chase. I've prepared one set of herbarium sheets, and today embarked on more. It's been so exciting talking botanic curiosities with other people interested in such geeky things! It inspires me to keep questioning.
The air shoots have interesting bract- or scale-like appendages near their tips, if you look very carefully. What are they for? What will they become?
