good news first, the Wikipedia and Index Fungorum datasets have been indexed and are back online.
The descendants issue you see is indeed some bug and should not be that way. I cannot explain it right now, but I’ll try to find the reason for it and reprocess the data accordingly.
You should still be able to rely on numDescandants for your browser.

>> If you search the GBIF backbone for Lembus you get 2 records. One synonym without descendants and one accepted taxon:

>> That looks correct to me and the synonym also does not return any children correctly:
