I was the one who wrote that. However, it's not up-to-date as this describes Macrolepiota rhodosperma. I don't think having a variety is of any use. It's just infraspecific variability.
Okay, no problem !
Why is does the "Über die komplizierte Gruppe der Safran- und Riesenschirmlinge: Die Gattungen Chlorophyllum und Macrolepiota" deliminated M. konradii as a separate species in M. mastoidea group though?
@jonasgruska I think that this is because there is still some uncertainty in this group. For the moment, I think that synonymising them in the wait of a complete revision of the complex is best as it'a already very difficult to keep the identifications quite clean (there are many misidentifications). We can split them when we have convincing proofs and morphological criteria to work with.
VELLINGA (2001c) synonymisiert M. rickenii und M. konradii mit M. mastoidea, auch aufgrund molekularer Daten. Vermutlich sind noch einige weitere Arten ohne deutlichem Hutbuckel, wie M. fuligineosquarrosa, M. psammophila und M. subsquarrosa, nahe mit M. mastoidea verwandt. Manche dieser Arten werden aufgrund des fehlenden spitzen Hutbuckels bisweilen auch in die Gruppe um M. excoriata gestellt (z. B. von CANDUSSO & LANZONI 1990, Bon 1993a). Die Abgrenzung der Arten in der Gruppe um M. mastoidea erfordert noch genauere Studien.
Seems that the interpretation of this name in Friebes, 2013 could fit to something like this observation:

I think it would make sense to sequence more fruibodies with distinctive floral pattern on top of it's pileus like this one, if they can be grupped together in separate taxon.
Maybe we can add them as varieties or form, but I think giving them specific rank is premature.
According to this website : https://www.mycodb.fr/fiche.php?genre=Macrolepiota&espece=mastoidea
A lot of the species which were accepted are in fact variety of M. mastoidea. In this case, should M. konradii have been merged with M. mastoidea var. konradii rather than the full species ?
