Glowing wood and foxfire

I recently had an enquiry from someone who noticed during the middle of the night that their pile of split firewood was emitting a faint glow. What could cause this?!

Apparently there are fungi that grow in rotting wood that can emit light through luminescence. The phenomenon is sometimes called “foxfire”. I’ve never noticed this myself, but a colleague who is a mycologist (expert on fungi) assures me it does occur in New Zealand. Apparently the light is very faint, and your eyes have to be well-adjusted to the dark.

More on foxfire luminescence.

If anyone has seen foxfire themselves, I’m interested to know more, particularly within a New Zealand setting; for instance, what kind of conditions and what kinds of wood are particularly conducive?

Winter Fungi

I know little about fungi, but I can still see that there are plenty around at present. Perhaps they’ve been enjoying the mild start to winter.

The following caught my eye during a recent Manawatu Botanical Society field-trip to the Branch Road track in the Pohangina Valley north of Palmerston North.

Geastrum – earthstar. I’ve never seen anything like this before, but very striking. © Leon Perrie.

Favolaschia calocera – bolete (= fleshy fungus with pores). This distinctive species is not native to New Zealand, but it is now amazingly widespread (including my garden). It turns up in even little-modified forests, and is evidently quite invasive, but I don’t know if it has negative effects on indigenous biodiversity. Apparently there are native species. One looks similar, but is white, and occurs on decaying tree-fern fronds. I’ve never seen it. © Leon Perrie.

For fungal novices like me, Landcare Research has a good online, picture-based identification key, which is how I identified the Geastrum and Inonotus above. Give it a go next time you happen upon an interesting fungus.

Te Papa has no* specimens of fungi in its collections.

So what is in Te Papa’s botany collection?

New Zealand’s main fungal herbarium is at Landcare Research in Auckland. Scion also maintains a fungal collection.

* actually, there is at least one – a vegetable caterpillar which is where a fungus parasitises a caterpillar. I’ll post a blog and picture of it at some stage. And, I’m not counting the fungal components of lichens, of which Te Papa has c. 7500 specimens, or ‘contaminants’ on plant (or animal) specimens.
