I spent the month of November 2013 in Australia on fieldwork for a project on the coevolution of certain plant groups and the specialized wasps that pollinate them. The plan was to collect the plants with their pollinators in the act, and to that end, I was accompanied by an entomologist, Dr. James Carpenter of the American Museum of Natural History. We also had collaborators from various herbaria and natural history museums across the continent.

The itinerary was a drive of more than 3,000 miles from Adelaide in South Australia to Brisbane in Queensland, following the River Murray in South Australia and then another river, the Darling, to Broken Hill, a mining city in New South Wales. From there, our route took us to Bourke, then Cunnamulla, and east to Brisbane. At both the start and end of the itinerary there was rain, so late spring flowers were in full bloom. But in between, things did not go quite according to plan because the Outback was in deep drought. In Cunnamulla, a police officer told us it had been more than a year since the last rainfall!

Caesius The Day: A Colorful New Australian Mushroom

Posted in New Plant Discoveries on December 26, 2013 by Roy Halling

Roy Halling, Ph.D., is Curator of Mycology in The New York Botanical Garden‘s Institute of Systematic Botany. Among his primary research interests is the bolete (or porcini) family of mushrooms, especially those found in Southeast Asia and Australia.


"Greenish Naked Foot"

Thirty years ago, I published a book, based on my Ph.D. thesis, describing collybioid mushrooms as they occur in the northeastern United States. These mushrooms, which have no real culinary value, are ecologically important because they decompose leaves and other plant litter in natural habitats. One of the common species in the northeast is called Gymnopus subnudus.

While exploring for bolete mushrooms (porcini family) on the Atherton Tableland in Queensland, Australia, I’ve often encountered over the last 20 years this unnamed collybioid mushroom with bluish green pigments. Even the cells at the edge of the gills are filled with the pigment.
