Culberson et al. (1977) discussed the chemosyndromic
variation within the P. pulla
group. For P. delisei they found the same
compounds as Esslinger (1977), but additionally
also traces of anziaic, loxodellic and stenosporic
acids, sometimes 4-O-methylolivetoric
acid and the unknown TE-6. Culberson
et al. (1977) recognized three chemical races
of P. pulla. Race /; Stenosporic, divaricatic and
accessory gyrophoric acid (1), and at least
traces of 4-O-demethyldivaricatic, 4-O-demethylstenosporic
and oxostenosporic acids.
Race 2: Divaricatic acid, stenosporic acid (*
traces), gyrophoric acid (*), 4-O-demethyldivaricatic
acid, oxostenosporic acid, and
sometimes the unknown PPY-compounds and
TE-6. Race 3: Perlatolic acid, and as minor
compound stenosporic acid.
The chemistry of P. pulla was also analysed
by Huneck et al. (1989); in this case the
chemistry corresponds to that in P. delisei,
reported above. Manrique (1989) presented
some HPLC chromatograms of trvo chemical
strains of P. pulla and two of P. delisei, adding
lecanoric acid to the minor compounds of
these taxa.
In Parmelin pulla, Clauzade & Rour
(1986) also included var. locarnensis (bpf ex
Rosend.) Clauz. & Rorx (with stenosporic and
gyrophoric (1) acids), subsp. glabrans (Nyl.)
Clauz. & Rorx (alectoronic and collatolic
acids), subsp. yryrenaica (Essl.) Clauz. & Roux
(gyrophoric acid (1) and unknown compounds),
and subsp. luteonotata (Steiner)
Clauz. & Roun (gyrophoric acid (i) and
unknown compounds).
The TLC analyses (one- and bidirectional) pgrformed
by me showed the presence of three
chemical strains:
Stain 1. This strain corresponds well to
the race 1 by Culberson et aL (L977) and the
"P. pulla tipo 2 by Manrique (1989): Stenosporic
acid (4-5, in an approximate scale 1-5),
divaricatic acid (1-3), accessory gyrophoric
acid (2-41-), traces of 4-O-demethyldivaricatic
acid, oxostenosporic acid and three
unknowns (among these possibly 4-O-de-
