I am also not smart but I’m guessing there’s a mushroom named for Gandalf (the name in the last panel, the cap in the second panel). And it’s a saprotroph (sp? wood eater?). And it’s something else that I don’t understand. Pretty sure a bivalve is a mussel.
It’s not referring to a valve but rather the structures protecting the spore bearing tissue of the mushroom. Bivelangiocarpic means there are two veils protecting the spore bearing tissue until that matures. My source: https://davidmoore.org.uk/21st_century_guidebook_to_fungi_platinum/Ch12_04.htm
Found a picture of it and looks like the cap on gandalfs head might not be the mushroom in the meme https://scd.landcareresearch.co.nz/Specimen/PDD 106954
I suspect it was named after gandalf because it seems to live in New Zealand.
