Phaeographis mucronata
In this case covering old bottlebrush fruits. Distinctive in that the spore often have small tags at either end.Saturday, April 08, 2006
Normandina pulchella

Chrysothrix candelaris
Teloschistes sieberianus
This specimen has been removed from the bark on which it was found. Note that the apothecia do not have marginal fibrils.Tuesday, April 04, 2006
Unknown 007
Teloschistes velifer
This species of Teloshistes is distinctive in that the underside of the lobes have large open soralia with coarse green soredia. Monday, April 03, 2006
Pannaria sphinctrina
Bright lettuce-green, becoming uniformly cinnamon-brown when stored.Coenogonium implexum

Cladonia confusa
In large mats on volcanic rocks. Favours sheltered depressions.Lecanora
Pertusaria sp.
Unknown 004
Hypogymnia subphysodes
On bark. Inflated lobes with wrinkled black cortex beneath, brown near young apices.Unknown 002
Probably a Lecanora. On bark with a graphid. The apothecia cover more than half the surface and appear to be deformed through crowding.
Physcia poncinsii
This example is on basalt but often found on bark. The soralia are more or less crater-form. The dry surface appears chalky grey.
Protoblastenia rupestris
This lichen can be seen on footpaths, concrete surfaces and asphalt. While it is establishing the thallus is immersed with only the convex apothecia visible (as in this image). However older thalli do appear above the substrate. In wet weather this lichen forms lighter circles against the darker background of micro-lichens and algae.
Physcia adscendens
Distinctive because of the terminal helmet-shaped soralia. The soredia cover the interior of these unusual hollow structures. When moist the soredia are greenish and more obvious than when dry because they contrast with the thallus. The narrow lobes have long marginal cilia. Apothecia are scarce, there is one in this image. I think that apothecia only appear on older thalli.
Teloschistes chrysopthalmus
A very distinctive lichen which is often found on twigs. The thallus is usually smaller than 4cm diam. Relatively short lived. Usually fertile with many marginal fibrils on the apothecia.
