The tree

This was growing in a tree stump in the bush. I very much doubt that it was an introduced species. It was most likely a eucalypt but I couldn’t say which one.

Yes … and no.

Tasmania’s climate is more similar to New Zealand’s than Australia. The English penchant for gardening has introduced many non-native trees, plants and fungi (hitchhiking on roots) to both places. Douglas-fir lumber from Oregon became so available in Australia that lumber was called “Oregon” there in the 1850-1930 period. Tremella mesenterica is relatively easy to cultivate, even when not intended. I learned that from innoculating fresh Douglas-fir stumps at Paul Bishop’s tree farm with “Laetiporus sulphureus” obtained from Fungi Perfecti in the early 1990’s (1992?). No L. sulphureus grew on the stumps. Tremella mesenterica fruited abundantly. BTW, by 1995 it was known that L. sulphureus is hardwood-specific. A similar but different species, L. coniferoides grows on Sitka spruce, Douglas-fir, and Western hemlock. My cultivation “failure” apparently proved this.

It’s growing in Australia

unless it’s on a introduced tree (and even then I would hesitate) we shoudn’t be putting northern hemisphere names on stuff from Tasmania.

Dacrymyces palmatus vs. Tremella mesenterica

According to Aurora, this is D. palmatus. It appears to be growing on some kind of oak. T. mesenterica is similar, but is found on conifers, most frequently Douglas-fir in my area. They also differ by basal attachment and by microscopic features. This is growing on a hardwood, so must be D. palmatus.
