Flora of Australia, Volume 56A: Lichens 4

Covers some of the most spectacular and ecologically significant Australian lichens. This volume provides treatments of Pertusaria and Lecanora, two of the most species-rich crustose genera on rock and bark in Australia. Also included here is Usnea, a genus of robust and often luxuriant lichens ranging from almost rigid tufts on exposed, alpine rocks to metre-long skeins hanging from the canopies of temperate rainforest trees. Complete or partial accounts of nine families are provided in Volume 56A, including 17 genera and 287 species and infra-specific taxa. This brings to 1168 the number of Australian lichen species and infra-specific taxa treated in the four volumes published so far.  A paperback is also available [stock id 11143].
