NADENE REPLIES: we’ve run information on this pesky invader on a couple of occasions and we’re happy to keep sharing what we know.
‘Nostoc’ (or blue-green algae) is technically a cyanobacteria and it is very difficult to eradicate. It can thrive in dry valleys in the coldest parts of Antarctica right through to tropical habitats, and has been resurrected after 100 years in a dried state. It is particularly good at coping with water stress – it can lose 70% of its weight in water before cell metabolism is affected, which is why it seems
to dry off and die on your driveway gravel or concrete areas in summer, then reappear in winter.
Nostoc is a single-celled organism so it is easily dispersed on the wind and can be spread on people’s shoes and vehicles. It’s unlikely we’ll ever be rid of it, so it’s best to think of it like you would gorse: strike when the affected area is small, and then keep up the effort over time. On small areas, try boiling water – nostoc, like all bacteria, isn’t adapted to high temperatures – but if it’s over a larger area, you can try a herbicide like glysophate. However, as noted, it will return, and you will need to keep up your efforts to stop it spreading.
ALIEN INVADER 2
I wonder if someone can identify what this blob is? We have had this fungal (?) ‘creature’ appear here maybe two or three times over recent years, lasting several days.
These photos were taken in February when I was irrigating. We live in a subalpine area where the growing seasons are short but hot, the winters wet with hard frosts and sometimes snow. The natural soil is sandy riverbed and acidic, but the vege gardens where this has grown are beautiful, loamy, mature, no-dig gardens in low container beds.
My neighbour has an extensive garden but hasn’t seen anything like it before.
When touched it feels just as it looks!

The Legend of Mt White Station
By Gerald Sandrey Mary Egan Publishing, hardback, 168 pages $60 The diverse and desolate country that makes up Mt White Station has held an irresistible allure for decades. Many have committed themselves to the extreme weather and isolation of the place only to finally admit defeat, while others have endured, raising families and forming bonds with their fellow station workers and the land itself. This book pays homage to the colourful characters and high country legends who have lived and worked at Mt White station, and to its rugged and beautiful landscape. Enjoy totally tasty barbecue food, cooked and eaten anywhere you happen to be. Chris Fortune offers practical, reliable advice on essential equipment, preparation, ingredients, and simple do’s and don’ts to ensure safe and successful results. He also answers key questions on basting, marinating and brining; why some things fail; cooking for a crowd; best cuts of meat to barbecue and why; and how to use cheaper cuts with success.
