The earliest of the dye mushrooms, its colour varies from grey to green to a rich brown.

And some more rich colours

Rich colours from Velvet PaxWe used some fresh Velvet Pax (Tapinella atrotomentosa or Paxillus atrotomentosus) for the workshop (see the second image below), then what I had left sat in the freezer for a few weeks. I ended up with a strong concentration of mushrooms, resulting in one of the best browns ever to come out of my dyepots (there’s a hint of purple in that brown – I swear it!). The two brown skeins were mordanted in copper, while the green were mordanted in iron. The small grey skein was mordanted in alum.

After these skeins came out, I put the mushrooms back into the pot and they’ve been brewing on top of the woodstove for a few days. I have high hopes for the second exhaust, but first I need to do some more mordanting.

The small skeins from the workshop obviously came from a weaker dyebath; the mordants are alum, iron and copper.

Velvet pax – despite the heat

We went into the forest on the weekend, not expecting to find anything in the way of fungus (given our current long spell of hot, very, very dry weather), so I was thrilled to find one mossy stump with four of these beauties – Paxillus atrotomentosus, aka Tapinella atrotomentosa) growing out of the wood. I’d found a couple on this same stump last year and expected to find some later in the month, after our usual August rains.

These were clearly drying out – note the cracks on the cap – so I picked them, but left the other button-sized speciments to flesh out a bit.

The other little mushroom I referred to in my last post came out of the freezer this week and is currently sitting in a jar of water in the full sun, and the liquid has turned brown.  I’ll let it cook there until our next rain (please let that be soon!), then see what colour results.

Mushrooms are popping!

Velvet pax1 Aug11_08I’ve found a couple of small Velvet Pax (Paxillus atrotomentosus or Tapinella atrotomentosa) in the forest behind us, one on a mossy stump and one at the base of a dead tree (on which are also growing some varnished conk). I was surprised to find them so early, but apparently the June rains brought them out. They weren’t as large as those in the image here, but they were still unmistakeable, with the brown velvet on their stems and the purplish discoloration where the bugs or squirrels had nibbled at them.

This is the mushroom that has been known to give a purple colour, but here the alum-mordanted sample (top) has a definite greenish cast, while the iron-mordanted sample below is a nice army-blanket green.

The second mushroom I found is currently sitting in the freezer; I’m wondering if that might make a difference to the colour.
