Unable to look of all observations of a species.
Take, for example, Macrolepiota zeyheri which has two varieties telosa and zeyheri. But observations have not recorded the variety. This is common that subspecies are often ignored. The problem that it is is hard to see the observations of the species. OK you can through the observations but this is harder.
The solution allows you to pass through all the species irrespective of the parts. This should be an option.
