Graphina hartmanniana MillI. Arg., an additional synonym<br />

for Dictyographa cinerea (C. Knight & Mitt.) Miill. Arg.<br />

Alan W. Archer<br />

Mrs Macquaries Road, Sydney 2000, N.S.W., Australia<br />

The genus Dictyographa (Muller 1893) is characterized by sessile, simple, black<br />

lirellae, hyaline, muriform ascospores, and anastomosing paraphyses. Dictyo·<br />

grapha cinerea (C. Knight) Mull. Arg., described from New Zealand (Muller 1894),<br />

was recently reported from Australia (Archer 2000). A re-examination of a closeup<br />

photograph ofthe holotype ofGraph ina hartmanniana Mull. Arg. found it to be<br />

identical to a similar photograph ofD. cinerea. This superficial identity was confirmed<br />

by reference to Muller's original description of G. hartmanniana (Muller<br />

1882), and a later examination of the holotype ofG. hartmanniana (Archer 1999).<br />

In particular, both species have conspicuous, sessile, simple black lirellae with<br />

completely carbonized proper exciples, they lack lichen compounds, and their ascospores<br />

are similar in size, viz.: D. cinerea 24-28 x 10-12 11m, 6-7 x 2-4-locular;<br />

G. hartmanniana: 19-25 x 6-8(-11) Ilffi, 6-8 x 2-locular.<br />

In the protologue to G. hartmanniana, Muller commented that the species resembled<br />

no other known species. The inconspicuous nature of D. cinerea could<br />

explain why no other specimens of"'G. hartmanniana" have been collected since<br />

Millier's original publication. The species is now known from Queensland and New<br />

South Wales as well as New Zealand.<br />

Notes on the heterogeneous genus Psoroma s. lat. in New Zealand<br />

Abstract: Recent changes in the circumscriptions of the genera Pannaria and<br />

Psoroma have led to the recognition ofan increasing number of"green" species of<br />

Pannaria formerly included in Psaroma. Comments are made on current knowledge<br />

of the heterogeneous genus Psoroma, with special reference to New Zealand<br />

species. Five new combinations in Pannaria are here proposed, viz. Pannaria<br />

allorhiza (Ny!.) Elvebakk & D.J. Galloway, Panna ria athroophylla (Stirt.) Elvebakk<br />

& D.J. Galloway. Pannaria durietzii (P. James & Henssen) Elvebakk & D.J. Galloway.<br />

Pannaria euphylla (Ny!.) Elvebakk & D.J. Galloway and Pannaria patagonica<br />

(Malme) Elvebakk & D.J. Galloway.<br />

Introduction<br />

In the major temperate biomes ofthe Southern Hemisphere, viz. southern South<br />

America, south-eastAustralia, Tasmania and especially New Zealand, the family<br />

Pannariaceae is both highly speciose (often at a local as well as a regional level),<br />

and of considerable biomass, in forest, scrub, and grassland landscapes, with the<br />

following genera being represented there: DegeliaArv. & D.J. Galloway, Erioderma<br />

Detailed studies of Pannaria s. lat. and Psoroma s. lat. in the Southern Hemisphere<br />

are currently in progress and will be reported in detail elsewhere (Elvebakk<br />

in prep.). However, as part ofrevisionary work for the forthcoming second edition<br />

ofFlora ofNew Zealand Lichens (Galloway in prep.), we here propose transferring<br />

five additional species of Psoroma to Pannaria, in line with present thinking.<br />

Psoroma s. str., as pointed out by J f/Jrgensen & Wedin (1999) and Jf/Jrgensen (2oo0a,<br />

2002a) refers to the Psoroma hypnorum group oftaxa, but there are at least two<br />

other groups of species within Psoroma that will eventually need formal recognition<br />

(Elvebakk, unpublished observations). As a first step towards clarifYing the<br />

limits of Psoroma s. lat., we here transfer five species currently in Psoroma to<br />

Panna ria, although Pannaria too might in the future also prove to be heterogeneous.<br />

1985: 479); however, current studies indicate that these records may refer to at<br />

least one undescribed species with deviating chemistry, but as yet only part of the<br />

material available for study has been analysed. Until this question is resolved,<br />

Pannaria patagonica is best considered a doubtful species in New Zealand.<br />

How are these bipolar lichen distributions explained? This was discussed in a<br />

preliminary way by Galloway & Aptroot (1995), and at present biogeographers<br />

suggest two major frameworks: (1) VlCariance models. Allopatric speciation resulting<br />

from some kind ofgeographical barrier separating a formerly continuous population.<br />

Rafting of fragments from earlier landmasses such as Gondwana, and/or<br />

the accretion of terranes ofexotic origin. There are several competing scenarios,<br />

but as yet none has been rigorously tested, partly because alpine lichens of the<br />

Southern Hemisphere and oftropical mountains are still not adequately and accurately<br />

known, nor is the geology ofcomposite present-day landmasses known with<br />

certainty. (2) Long-distance dispersal. This is now much more fashionable in discussions<br />

ofplant distributions in the Southern Hemisphere than it was a decade<br />

or so ago (see for example Pole 2001). The alpine vegetation for the South Island of<br />

New Zealand, although physically isolated in the southern ocean for some SOMY<br />

and with a high degree ofendemism, is nevertheless comparatively young, adaptive<br />

radiation having occurred after long-distance dispersal during the late Miocene<br />

to early Pleistocene (McGlone et al. 2001, Lee et al. 2001). Unlike the flowering<br />

plants of alpine New Zealand, the alpine lichens have apparently not speciated<br />

in situ at all, with only a few endemic taxa developed such as Labyrintha<br />

(Malcolm et al. 1995). Some undoubtedly have arrived in relatively recent times in<br />

the West Wind Drift, but others could well be truly Gondwanan or even earlier<br />

relicts.<br />

@<br />

AUSTRALASIAN LlCHENOLOGY 63, July 2003<br />

The persistence oflichen communities in extreme, high-alpine environments at<br />

high latitudes in both hemispheres is a well-recognized phenomenon (Galloway &<br />

Aptroot, 1995, Adler & Calvelo 2002), but still without a single unifying explanation.<br />

Recent developments in phylogenetic systematics of fungi have shown that<br />

the lichenized state is indeed a very ancient symbiosis stretching back to the very<br />

beginnings ofthe colonization ofthe earth by living systems, and that lichen associations<br />

are the likely ancestors ofCree-living Ascomycete fungaIlines (Lutzoni et<br />

al. 2001). There is evidence that gains oflichenization often are followed by losses.<br />

It is axiomatic that earth and life evolved together, so in seeking an explanation<br />

for the phenomenon ofbipolarity in lichens, increasingly more sophisticated (and<br />

hopefully cheaper) molecular methods, plus advances in knowledge of composite<br />

geological areas, will be powerful tools to help provide some realistic answers.<br />
