not at all: Fries described
Polyporus australis (as this fungus was originally known) from material "
Ad truncos arborum in insulis Oceani pacifici" - which even those with no Latin should be able to understand

; so you can see it does have a very widespread distribution
for a long time it was known as
Polyporus adspersum Schulzer (described in 1878), later (1969) transferred to
Ganoderma; Steyaert muddied the waters by describing
Ganoderma europaeum in 1961; all these later names have been reduced to synonymy -
australe is the earliest valid name (but you may find the fungus in older books under one of the others)
interestingly Leif Ryvarden in Vol. 1 of
Polyporaceae of Northern Europe states that it was not then known in Fennoscandia; that situation may have changed since 1976 of course, but a northern limit to its distribution seems likely
