A bit of coral, a bit of purple

This extremely dry season yielded me a handful, literally, of coral mushrooms—a clump of Clavulina coralloides (a white coral) and two of an orange coral, Ramaria (R.carnata, I believe). With nothing to lose and a desire to dye with something other than Phaeolus, I decided to put the two clumps together and see what happened.

The corals went into a fine-mesh bag, then into the dyepot with a silk chiffon scarf previously mordanted with iron (and tied with a few loose knots for mottled colour). I initiated my new induction burner, which I found to be perfect for heating the dyebath slowly. Determined not to lose any chance of obtaining the fragile purple (in the natural dye world, purple is known to lose its colour if cooked above 160 degrees F), I hovered over the dyepot as any good witch would, monitoring the temperature carefully.

To my surprise, the silk began to darken at 110 degrees. and I let it heat to 130 before pulling it. You can see, a bit off centre, the little bundle of yarn samples I also threw into the pot. These are mordant samples—a strand each with no mordant, alum, iron, and copper—that I put into every dyepot to monitor its progress. With these, the iron strand was also developing a purple cast, while the other mordants were pretty much doing nothing.

Here’s how the iron yarn sample turned out, though perhaps not as obviously purple in real life. Below is the scarf.

I tried an exhaust dyepot with a piece of silk roving, but the corals had been truly exhausted. I got no further colour.

I have every hope that next year the forest will produce mountains of coral, and I plan to have all manner of silk mordanted and waiting to be transformed by this royal colour.

Time lapse Phaeolus

I  feel blessed to be living with a rainforest just outside my door, never more so than during mushroom season. Even though this year has been terribly dry and the season late, with few mushrooms to be seen so far, the  Phaeolus schweinitzii, or Dyer’s Polypore, have proved the exception, guaranteeing  some golden dyepots this year, at least.

I can always count on one old, mossy stump near a swampy area to come through with a beautiful specimen, and this year it surprised me with twins on its top surface. This provided the perfect opportunity to photograph how their growth progressed over the three weeks after I spotted them, by which time they were in prime condition and fairly begged to be harvested.

Amazing what they accomplished in three short weeks!

Baby blue promises future green

I went back to a spot where I’ve found Hydnellum caeruleum in previous years, but since I didn’t see any last year or the year before, I wasn’t expecting to find anything, especially with  the extremely dry weather this year. So imagine my delight when I found five of these little beauties!

I normally find these earlier in the season—late August/early September. This little cluster clearly started earlier, probably after the day of heavy rain we had in mid-August, and have been sitting and waiting ever since. Now, following another day of rain a couple of weeks ago, they’re sending out new, pastel blue growth, which will soon age to brown as the caps open up. (A measure of the severity of this drought: we can remember every day of rain since June—two by my count, plus a few inconsequential showers.)

Last year I left a growth of Hydnellum aurantiacum to mature in place, and when I got back to them they were a slimy, black mass. I put them through the dyepot anyway and got the usual lovely green, so I plan to leave these for a while before I harvest. Except for one specimen that will go to the Sunshine Coast Mushroom Festival October 14, where any and all specimens will be welcome.

Waiting for the rain

Summer singles yarn

This was one of the driest summers ever on the Sunshine Coast (I’m so grateful it wasn’t like this last year, leading up to the Fungi & Fibre Symposium!). The long-range weather forecasts keep teasing us with promises of good, long rains, then amend their predictions downward until, as is happening today, we end up with a few sporadic showers.

So I’ve been biding my time by spinning from what’s left of last year’s dyeing. These colours came from Cortinarius semisanguineus (Dermocybes—the pink), Phaeolus schweinitzii (Dyer’s polypore—the green, premordanted with iron), and Gymnopilus luteofolius (the pale yellow), which I carded together, then spun into a singles lace-weight. It contains a fair bit of silk and should knit up beautifully. (This skein just went home this morning with an avid knitter from Edmonton—Kyle, if you’re reading this, could you send me a photo of what you decide to do with it?)

Summer spinning

Mushroom season won’t be long now—I’ve found a few early Tapinella already, although most will appear later—so I’ve been playing on my spinning wheel with some of the colours I got last year. This batt contained Phaeolus gold and green, Pycnoporellus peach, and a bit of Sarcodon blue.

With quite a lot of the blue already in my stash, I decided to ply the single, spun from the batt, with a blue single, resulting in this pleasant combination:

The yarn

As usual, I’m ending up with more yarn than I have time to do something with; perhaps this yarn will end up in someone else’s stash, someone who can put it to good use.

Rethinking Ramaria

Ramaria largentii

My freezer has been home to masses of frozen Ramaria collected for the Fungi and Fibre Symposium dyepots, but I wanted to be sure it would give some good colour after being frozen for nine months. My earlier experiments with the frozen version of this mushroom resulted in a decent purple, but I didn’t want to take a chance on seeing a dozen international visitors hovering over a dyepot, watching and waiting for purple. And ending up with a blah beige.

So this lovely orange coral appeared in my Back Forty at the perfect time, when plans for the event are ticking along nicely and when my hands really needed to get into some dyepots. The coral came home with me and went straight into my sample dyepot along with a few strands of iron-mordanted yarn.

The results amounted to a revelation. I recant my previous musings about frozen Ramaria and about keeping the dyepot temperature on the low side. Here’s what happened (laid out on grey cardstock—the colours are true, at least on my screen) :

Ramaria samples, fresh and frozen

First, it doesn’t appear that the purple from Ramaria is quite so finicky as the other purple-bestowing mushrooms when it comes to temperatures (specifically Tapinella atrotomentosa and Omphalotus olivascens, which need to be watched carefully and pulled at ~160° F). Clearly the dyebath shouldn’t be allowed to reach boiling, but 170° F was the optimum for the first two sets of samples.

My second discovery: freezing Ramaria works if done for a short time but not for the nine months I subjected my stash to. So I returned the Symposium orange coral to the forest floor, and now I’m hoping for an outstanding harvest this year so our registrants won’t be disappointed.

At the same time as I found the Ramaria, I also found Clavulina coralloides in various stages of infection with Helminthosphaeria clavariarum, a fungus that routinely parasitizes this little coral.

Since I was planning on doing some sampling anyway, I decided to try this one too—with the darkest of the infected coral—on the off chance the deep purple of the parasite might translate into the dyepot, again with an iron-mordanted test strand.

Clavulina samples

More grey than purple, but clearly darker with more heat. Worth playing with some more? I don’t think so.

If it seems like it’s been a while since I last posted . . . it has. Despite the dry summer, the mushrooms are coming out now, so most days we’re out scouting our favourite spots.

We discovered one particular patch of Lobsters (Hypomyces lactifluorum) two years ago and hadn’t been back since, but we decided to check it out this morning. Strangely enough, there were very few other mushrooms around, but our patch didn’t disappoint; we came home with a good ten pounds of the beauties, most of them already breaking apart. But that doesn’t matter to me—I’ll strip the coloured bits no matter how fragile or smelly their hosts might be.

And it was interesting to see the various stages of progression: from an uninfected Russula brevipes to one starting to show a bit of colour, to one in the full stages of orange.

My evening work is cut out for me—paring mushrooms! Now we’re certain to have a strong Lobster dyepot for next year’s Fungi & Fibre Symposium. (Have you marked your calendars yet? October 17-22, 2016, Madeira Park, BC.)
