Topic: Pseudochantransis pygmaea
The name Pseudochantransis pygmaea appears to only exist on the NBN Atlas when you google it, and has a taxon group of fungus. Pseudochantransia pygmaea gets more hits and is listed as an algae - this makes more sense as all records on the NBN are from the Rivers Macrophyte Database, but I don't know enough about either group to say this with any confidence!
