Can you please send the original photo to help@inaturalist.org? I’d be curious to test it out. Please make sure its metadata is intact.
Those seem like logical suggestions to me. That totally looks like a photo of rabbit droppings, mushrooms, or snails. Cropping can help a lot, I suspect you might get very different results if you cropped the photo to the subject - most gall photos on iNat are pretty tight shots, in my experience. Remember that iNat computer vision isn’t trained to identify taxa, it’s trained to identify iNaturalist photos of taxa. It processes at your photo and spits out results that say “this looks like other iNaturalist photos of [X taxon]”.
