Fuzzy matching on genus name

[Alectoria]

I noticed that fuzzy matching in GNR did not work in the case of "Buphtalmum salicifolium". The typo is in the genus name (correct spelling: Buphthalmum salicifolium; Asteraceae).

Here an example with the R taxize package and the name (incl typo in genus name). I just get the genus name from IRMN (but not the correct spelling):

gnr_resolve("Buphtalmum salicifolium")
       submitted_name              matched_name                               data_source_title score
1 Buphtalmum salicifolium Buphtalmum Linnaeus, 1753 Interim Register of Marine and Nonmarine     
Genera  0.75

When suppliyng the correctly spelt name, I get a match - so the name is included in the DBs:

gnr_resolve("Buphthalmum salicifolium") %>% head(2)
        submitted_name             matched_name data_source_title score
1 Buphthalmum salicifolium Buphthalmum salicifolium              NCBI 0.988
2 Buphthalmum salicifolium Buphthalmum salicifolium          Freebase 0.988

Other taxon names with a typo in the genus name work just fine ("Stippa" should be "Stipa"):

gnr_resolve("Stippa pennata") %>% head(2)
  submitted_name     matched_name data_source_title score
1 Stippa pennata Stipa pennata L. Catalogue of Life  0.75
2 Stippa pennata Stipa pennata L.              ITIS  0.75

I know this is just a single case but it really puzzled me.
Thanks for your effort.
