Genus Cortinarius, subgenus Phlegmacium in Tasmania
Ho affrontato la seguente tematica nomenclatoriasle. Desidererei che qualcuno (Alessio in particolare) la commentasse adeguatamente.
NOTES: ICBN Art. 33.12 (McNeill et al. 2006) states
that the names used by Fries as subdivisions of genus
and called tribes (tribus) in Systema Mycologicum
are to be treated as subdivisions of genus (for the
genus Cortinarius they have all been used as subgenera).
However, nothing is specified for the other
subdivisions (rankless) used by Fries (1821) within
the tribes, which sometimes have a different name,
in the following publications. These taxa, if used,
should be treated as “nomen novum” as indicated
in Art. 46.4.
In Brandrud et al. (1994) three Friesian subgeneric
taxa are typified: Cortinarius Section Heterocliti
(ex Fries S.M., p. 213), Phlegmacioides (=
Phlegmacioidea, Fries S.M., p. 222), and Mollipedes
(Fr. Epicr., p. 291). These sections are considered
valid only from the time of the actual publication
(Sep 1994). Section Phlegmacioides Fr. ex Brandrud
et al., however, is illegitimate since, prior to it, the
section Patibiles had been validated (Bidaud et al.
1990.)
In addition, Agaricus sect. Phlegmacioides Fr.:
Fr. is incorrectly written since Fries sanctioned
species not infrageneric taxa. Phlegmacioidea was
used by Fries (1821) as a subdivision of tribe XIX
(Inoloma) in genus Agaricus, tribe Inoloma, not
Cortinarius. He probably used it as a nomen nudum,
without any specific rank; to interpret it as a section
of Cortinarius is, in my view, arbitrary.
