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.

Hydnellum caeruleun

Blue-gray Hydnellum

This image is a bit fuzzy, but it does show the Hydnellum “teeth” clearly. This is the first H. caeruleum I’ve ever found—the distinctive blue-gray border gave it away. It was a real surprise, given how dry it’s been lately, but these were growing in a shady spot near a stream.

These were in the same area as a good number of H. aurantiacum, so I’ll be able to do some comparison dyepots later in the season. For now, I’m mordanting as much fibre as I can, to get ready for the great mushroom pop-out that’s sure to happen soon. (Rain is predicted for later this week, so I have high hopes.)
