Snow lichen

Description:

When this lichen fruits it presents a delicate net-like fungal body consisting of tubes, leaves and arms all with holes of about 3-5mm diameter.
En masse it can resemble a light sprinkling of snow. This display covered many hundreds of square metres.

Habitat:

In a national park on a cleared fire track with very sandy soil. Decent rain had fallen about 4 days previously.

Notes:

Pulchrocladia retipora was the first Australian lichen to be described in a scientific publication.
