December 2015. A fungus from the forest floor of Palau. It is about 10-15 cm (4-6 inches) tall. They appeared after rain, which is another reason I suspect fungus. Can anyone tell me what this is

It was said to be a species of Ramaria, the coral fungus.

Some Australian examples are given here on the Queensland Mycological Society website: NonPests/Fungi/Coralfungus,Ramaria/tabid/6941/ctl/Edit/mid/10875/Some%20Australian%20examples%20are%20on%20the%20Society%20website:%20%20http://qldfungi.org.au/resources-2/foq-main-page/foq-species-list/icicles.

A member from Jamaica said that it was like the yellow tuning fork, Calocera viscosa.
