Sorry Chris, they were only small and I don,t like risking breaking the stem to get a better photo. They were growing on a path made from wood chips, on peat.

Never mind, we will just admire the photograph.

Interesting, what would be the explanation for this? - translation, please.

Gabriela,

Knivkjuke has been used in many ways due to its rubber like consistency. It has been used as pincushion and for keeping other steel tools in place, but also as medicine. If it really hinder rust I do not know. Can't find any scientific article about it and I have not tried myself. Maybe the dense consistency hinder O₂ and/or water to react with the steel or chemicals like triterpenes do the same.

[Gabriela]

Thanks Trond. I thought the article linked was given explanations. Interesting anyway.

Rather brilliantly, 'kniv' means 'knife', and 'kjuke' means 'southeastern inland counties'. At least that's what it say on Google translate, so it must be true!

These photos were taken in beech forest on the Kiwi Burn loop track ( near Lake Te Anau) on Dec 10th.

Pseudocyphellaria billardierei (or at least that's the provisional identification of my lichen guru). This spectacular foliose lichen was growing on a tree trunk.

Thanks for showing these David, lovely images.

The beauty of the lichens in all their complexity never ceases to amaze me!

-------- Very well said, Gabriela!

[Paul Cumbleton]

Their complexity just got more so - for the past 150 years we have believed lichens have a dual nature,  a combination of fungi with either algae or cyanobacteria. Just this year research was published showing that for many lichens a third organism is also involved - another fungus. So many are a combination of three organisms, not the two we had thought. There is a good concise account of this here: http://theconversation.com/lichens-may-be-a-symbiosis-of-three-organisms-a-new-order-of-fungus-named-63334

Thanks Paul - this is very exciting news.
The lichens keep giving us good lessons for long-term, peaceful coexistence
