Graphis longiramea
Müller Arg. (1892: 225)
.
Type:—
INDIA
.
Manipur
:
G. Watt
87
(G!,
lectotype
, here designated)
.
Thallus corticolous, greyish to pale bluish gray, continuous, smooth to uneven, distinctly corticate and glossy. Lirellae immersed to erumpent, with thick lateral thalline margin, elongate, curved or sinuous, irregularly to radiately branched, labia convergent or slightly divergent, entire, disc concealed or slightly open (
leptogramma-
morph). Exciple laterally carbonized; hymenium clear; ascospores 4–8/ascus, hyaline, transversely 7–23-septate, 60–100 × 8–12 μm (
Lücking
et al.
2008
,
paratype
); 9–16-septate, 45–67 × 9–11 μm (
Awasthi & Singh 1976
,
holotype
); 11–15-septate, 55–62 × 10–12 μm (protologue).
Chemistry: stictic acid (annotation slips glued to
lectotype
in G from Nakanishi 1973, Patwardhan & Kulkarni 1975 and Awasthi & Mathur 1989).
Distribution and habitat
:—Reported from
India
(
type
locality),
China
(as
G. multibrachiata
Zahlbr.
and
G. zonatula
Zahlbr.
),
Japan
(as
G. awaensis
Vain.
) (
Lücking
et al.
2009
) and
Thailand
in
Loei province
(
Poengsungnoen
et al.
2010
). There it is growing on bark in lower montane rainforests and tropical rainforests.
Graphis longiramea
was not present in our collections.
Remarks
:—Some dissens exists about the designation of a
lectotype
for this species. It became necessary because in the protologue no material at all was cited. The only published lectotypification we could trace was that of
Awasthi & Singh (1976)
who selected
G. Watt 6981
, housed in BM. Patwardhan & Kulkarni as well as Awasthi & Mathur (both on annotation slips), selected
G. Watt 87
, housed in G, as
lectotype
. Without any doubt, Müller’s protlogue is based on the latter specimen. Very strong evidence is the spore septation and dimensions written in Müller’s handwriting which are absolutely identical with those in the protologue. We therefore superseed the earlier lectotypification and designate the material in G as a new
lectotype
for
Graphis longiramea
.
