Cobalt Crust. Terana caerulea

This beautiful blue crust fungus is listed in some of the older books (my Michael Jordan's Enc) as Pulcherricium caeruleum.
I haven't seen it for a few years and when I looked it up it is described as "infrequent". The books say most commonly found on Ash or Hazel as was this specimen, however I have found it in the past growing on Bramble. It can be used to produce an antibiotic named cortalcerone that inhibits the growth of Streptococcus pyogenes, a spherical bacterium that is responsible for an abundance of infections, so one of the more useful fungi.

  1. Yesterday, coincidentally (or not), a voluntter at the Botanic Garden came to see me as he had found a small bit of purple fungus on a log (I don't know where he lives but it's Carmarthenshire). Hmm, might be totaly unrealted but it may be that time of year for this to be fruitng. I've never seen it - must keep an eye on local ash and hazels..

  2. A nice picture of this attractive species --- I have seen it called a 'blue lichen'. Found during the winter 1/2 of the year ---- gets dull when dried out and sometimes found when turning fallen branches over as it may be on moist undersurface. Last week I was told by a friend, whose son has a smallholding near Llanarthne, that there were bright blue patches on branches in their hedge.
