Concerning the use of the International Code of Botanical Nomenclature, I
have quite a different understanding from that of Dave Brayford
"Sorry to stir things up, but the replies concerning classification of
were slightly up the creek, or at least out of date. The class"Ascomycetes"
rid of many moons ago and replaced by the subdivision "Ascomycotina". More
the Ascomycotina have been got rid of too - and elevated to the rank of
Phylum (= Division).
There are no classes, just orders and families. So now we have:
These changes are enshrined in the latest version of the International Code
Nomenclature and will be reflected in the forthcoming edition of The
Dictionary of the

According to the 1988 edition of the code, Division II, Article 3 states:
"3.1. The principal ranks of taxa in ascending sequence are : species
(species), genus (genus), family (familia), order (ordo), class
(classis), division (divisio), and kingdom (regnum)."
There is no statement in the code that I can find that "classes" of fungi
are not recognized, nor any that states what the names of recognized
divisions shall be. There is no recognition of the term "phyllum".
It is my understanding that the code treats naming of taxa and does not
treat the development or acceptance of any particular taxonomic systems
involving the use of these names. Thus, the code specifically does not
legislate that the Ascomycetes shall not be treated as a class, but must
be treated as a Division called Ascomycota. This kind of decision is a
matter of taxonomic opinion, left to the individual "taxonomist"; there
are many of these.
