When is a lichen not a lichen?

when its listed as a fungus!

This was spotted by wildlife trust colleagues in an output from us.  the species Cladonia chlorophaea (and indeed the "aggregate" for sens. lat. are assigned a taxon group of fungus rather than lichen.... All other cladonias are listed as lichens.

This led me to do some digging on the NBN Gateway, where the same problem seems to occur - see the species listings below, where I have given the details from the gateway of the species outputting as fungi, and also a couple of correct lichen examples.......

The only other example I have found in our admittedly depauperate lichen species for Cambridgeshire is that Hypotrachyna afrorevoluta is assigned a similar fate......
