NOTE: a noun used to describe another, and denoting the same person or thing, agrees with it in case: e.g. above: subdivisione (abl.) and Basidiomycotinis (abl.) even though one is a singular and the other a plural noun.

According to the Code of Nomenclature (Vienna 2006) (Article 16.3 Note 1) the term division and phyllum are synonymous: they refer to the same rank. By extension, the term subdivision is synonymous with subphyllum:

        sg.             pl.                  sg.                  pl.

Dat. subdivisioni  subdivisionibus   Dat. subphylo             subphylis
Acc. subdivisionem subdivisiones     Acc. subphylum            subphyla
Abl. subdivisione  subdivisionibus   Abl. subphylo             subphylis
According to the Code of Nomenclature (Vienna 2006) (recommendation 16A.2):

Latin endings for the ranks of subdivision and subphylum are:

1. for all plants except fungi:  -phytina
