Description: In the data portal, a search for scientific name "Amanita muscaria" provides the warning "We currently do not support occurrence searching by form, hence we are unable to search for the form Amanita muscaria". The records in the resultset are all infraspecific (http://data.gbif.org/occurrences/search.htm?c[0].s=0&c[0].p=0&c[0].o=Amanita+muscaria). As this is the name from the dropdown selector for the species name, the message is puzzling to a user. It does not appear if the taxon name is chosen from the hierarchy navigator behind "Classification includes Species: Amanita muscaria.

The reason seems to be that there are two nub concepts for this name, one at species level, the other at rank 8020.

portal db:
select * from taxon_name tn join taxon_concept tc on tn.id=tc.taxon_name_id where canonical = 'Amanita muscaria' and is_nub_concept=1 order by tc.rank asc;

The lower taxon rank goes back to http://ecat-dev.gbif.org/usage/7242052 (Amanita muscaria f. sp) of rank "form", which in turn points at Index Fungorum entry 361601 (http://ecat-dev.gbif.org/usage/110113412: Amanita muscaria f. sp. americana E.-J. Gilbert) of rank "f sp"

Additionally, this leads to confusing search results; apparently the infraspecific level is applied to identifications, so that records at species level are not found: http://data.gbif.org/occurrences/search.htm?c[0].s=0&c[0].p=0&c[0].o=Amanita+muscaria&c[1].s=5&c[1].p=0&c[1].o=NZ does not return any hits, even though records exist: http://data.gbif.org/occurrences/search.htm?c[0].s=24&c[0].p=0&c[0].o=471&c[1].s=25&c[1].p=0&c[1].o=56&c[2].s=14&c[2].p=0&c[2].o=PDD68683
