Psilocybe azurescens (Hammond)|

Spores from a print were streaked out onto 2% malt agar and incubated
in the dark at 25 °C. After 7 days, the healthiest looking
rhizomorphic colonies were isolated and transferred to fresh plates, also
cultured on agar slants in universal 1 oz glass bottles, for cold storage
in the fridge (5.0 °C).
Spores germinating on agar media
100 ml of organic rye grain and 80 ml of tap water was put in 1 pint
glass jars, with synthetic filter discs fitted under the caps, and autoclaved
for 20 minutes. Once cooled, 1cm wedges of mycelium were cut from
the agar and transferred, 3 to each jar. Lids were replaced, and
jars incubated at 25 °C for 7 days. Each jar was shaken to disperse
the rapidly spreading mycelium, and then incubated for a further 7 days.
Bulk substrate preparation
Fully colonised grain spawn was then used to inoculate "filter patch
spawn bags" . Each bag contained around 1 pound of mixed hardwood
sawdust and alder wood shavings/chips. Enough boiling water
was added to each bag to fully wet the substrate (approx. 5:4 substrate
: water ratio). These substrate bags were left to soak overnight
then autoclaved for 20 minutes, and allowed to cool. Around
½ pint of spawn was used to inoculate each bag of substrate and
these were left to colonise in a dark cupboard for 2-3 weeks @ about 20
°C. An alternative method for an attempted indoor patch was using
a plastic "washing-up" basin with a cased substrate consisting of wood
shavings and wheat straw (#1). As you can see, the fungus loves this
cellulose rich substrate.
Fully colonised wood/straw substrate
Preparation of outdoor beds
Patches were placed in different areas of the garden, during the summer around
#1. Under Rhododendron bushes, next to grassy lawn
#2. Under a pear tree amongst weeds/shrubbery
#3. Under an ash tree with surrounding gooseberry bushes
#4. In rich woody soil next to a compost heap
Each site was prepared by digging trenches about 6 inches deep, around
2 square feet. The trenches were raked over and lined with a thin
layer of moist, well rotted leaf litter/twigs. The colonised woody
substrate was broken up and spread out (about 1 bag per patch).
The spawn was then covered with another 2 inch layer of rotted leaves/twigs,
and finally covered with a thin (1 inch) layer of soil.
Preparation of an outdoor patch (#1)
Establishment of beds
It has now been about 6 weeks since preparing the patches and they
are all doing very well. Rhizomorphic mycelium can be observed creeping
over leaves, and spreading out into the surrounding leaf litter which comprises
the top 2-3 inches of the soil. The weather is cooling down
now (August) and it's getting wetter.
Rhizomorphic mycelium spreading over leaf litter
Watch out for slugs, which like to eat mycelium. The best
way of getting rid of them is to bait them with bread, and go out at night
with a torch and remove them (wearing gloves!). Wood lice were also present
and probably feasting on the mycelium. The other pests are
squirrels, which discovered the grain and dug a few little holes in the
patch under the pear tree (#2), soon after preparing the beds.
The patches were kept well-watered, mostly by rain, although they did
encounter some dry periods, which implemented the use of a watering can.
There was a light frost at the beginning of October, but the patches were
snug under the leaf litter.
#1 developed pinhead primordia, towards the end of October,
This was mainly in the area which had been covered by a thin layer of moss,
grass and leaves. The mossy turf had recovered and the mycelium could
be seen around the grass roots. Over the following two
weeks the primordia grew into mushrooms. Translucent caramel caps
with whitish stems which have a very strong bluing reaction were bruised;
truly an amazing species! They seem to grow very slowly at first,
but accelerate as they got bigger.
#2 is sparsely colonised at the surface, and not looking very happy.
Partially due to animals digging up the grain spawn, and the soil is very
clay rich with is not much wood content. The soil might be too moist.
#3 under the ash tree, is still looking healthy, and there are plenty
of thick rhizomorphic mycelium creeping out., It has a 2 inch covering
of leaves, and seems to be retaining moisture well, but no sign of fruiting,
#4 also hasn't started to fruit, but the woody ground is very well
colonised. The patch was covered with a thin layer of mossy turf:
this is keeping it moist, and there is a carpet of rhizomorphic mycelium.
The following images show the development
of primordia to "grown-up" mushrooms.
