On Aspicilia serpentinicola and some other Aspicilia names

GRAPHIS SCRIPTA 25 (2013) Aspicilia serpentinicola etc. 19
results from TLC analyses of material collected
by Anzi) and A. substictica Owe-Larss. & A.
Nordin (Owe-Larsson et al. 2007).
A. serpentinicola has been reported from
Finland (Vitikainen et al. 1997, Santesson et al.
2004), but material from H did not agree with
the type. Of six specimens investigated, three
belonged to A. laevata (or A. cf. laevata), one
to A. cf. indissimilis, one to Trapelia coarctata
and one to an indeterminable Aspicilia sp.
Hence, it can be concluded that A.
serpentinicola is not a member of the Finnish
lichen biota, and will thus be excluded from the
continuously updated online version of
Santesson’s checklist (Nordin et al. 2011a).

In the scanty type material of Lecanora
obvallata the majority of the apothecia are
conspicuously protruding and the surrounding
thallus blackened. Although he only had the
type at hand, Magnusson (1939) did not
hesitate to describe a new species based on
these strange apothecia, and without knowledge
of the habitat, he dared to guess that it
covered large areas and grew in a somewhat
moist situation. Apparently he did not consider
the presence of some more normally developed
A. verrucigera apothecia, which sooner suggest
that the strange apothecia are abberrant. [??]
This is not contradicted by other characters,
such as spore size and chemistry (stictic acid
complex). In fact the protruding apothecia are
more similar to those of A. laevata, a species
that is sometimes not easily distinguished from
A. verrucigera. Additional material of
Lecanora obvallata from Sweden, collected
and determined by Magnusson, belongs to A.
laevata.

lectotype selected here).
In his protologue Nylander notes that Lecanora
conglomerans is similar to L. caesiocinerea but
has a thicker thallus and larger spores. The
thallus thickness in Circinaria caesiocinerea,
however, is very variable, particularly when it
grows along seepages, and the few spores I
observed in the type specimen did not exceed
the extreme values of other C. caesiocinerea
spores measured (c. 21.5–30.5 × 12.5–20.5
µm). No substances were detected by TLC in
the type specimen, while aspicilin occurred in
various concentrations in the majority of other
C. caesiocinerea specimens investigated (24
out of 46).
