Myco-blitz, fruiting bodies

January 19, 2010

Upended and neglected by one animal forager, arranged and shot for identification by another.

In order to secure from landslide the steep incline that cups our house, my father planted it full of trees whose main job in life is to become really large. Something like 30 years ago, he introduced the deodara, pines, redwoods, and then predicting the gaps that come with arboreal maturity he planted the juniper chinensis; limb-rich, majestic, scented and kinetic. An eco-system from top to bottom, a plant wall, a live filtre of foam green sprays catching drifts of pine needles on heaving articulated branches before falling further, to carpet the man-made forest floor.

Suillus luteus or brevipes, ‘Sticky Bun’ or ‘Slippery Jack’ Bolete. 5 kilos from our garden!

This swathe of woodland, where animals live and pass through, whose shade and soft ground make it the ideal spot for wood splitting, and where wood in various states of being split gets stacked to dry. There’s an abundant humus layer that comes from moving all that wood around; prunings, rotten bark, saw dust, chips, all landing on the ground and getting covered up by the ceaseless needle fall. This is how the woodland harvest of one household inadvertently developed into an ideal environment for mushrooms.

Chroogomphus vinicolor / Pine Spike, under the redwoods, edible but not choice.

But these two discoveries were choice.

Culiblog author shows off one afternoon’s haul.

During a recent visit to the ancestral home, a two-day myco-blitz revealed more than 20 sorts of fruiting fungus, most remarkably, an easy 5 kilos of Suillus Luteus, or ‘Slippery Jack’ style boletes.

I’d like to give a shout out to the Mycelium Community for giving us a good show right through the cusp of the changing year, for feeding us and the trees that keep up that hill, well into 2010.

Here’s to a long future of collaboration, abundant fruition in 2010, and best wishes for superb soil fertility for all parties involved.

• The purple mushrooms turned out to be Blewits or Clitocybe nuda.

  More information on the Blewits right here. Next year we’re eating them.

  About the Chroogomphus vinicolor or Pine Spikes: These fungi are members of the family Gomphidiaceae which are agaricoid members of the Boletales (suborder Suillineae). Related to the genus Gomphidius (in which they were once classified), Chroogomphus are distinguished from Gomphidius by their lack of a partial veil. Members of this genus have been thought to be ectomycorrhizal with various species of pine, however, there is now evidence that all members of the Gomphidiaceae are parasitic upon other boletes. Specifically, Chroogomphus species are thought to be parasitic on various pine-associated Suillus species, with this parasitism often being highly species-specific.

  True to the description above, in the garden the chroogomphus vinicolor and the suillus luteus were growing ‘gregariously’ (as they say in mushroom talk) right next to each other.

  Another form, the chroogomphus ochraceus/Pine Spikes

  Lactarius rubrilacteus – We also had around 8 of these growing near the wooden path.

  The boletes in the garden were either suillus brevipes, aka short-stemmed Slippery Jacks or Sticky Buns.

  More on the the short-stemmed Slippery Jack or Suillus Brevipes.

  About the sub-order boletecae on Mykoweb.

  Or were they possibly the Suillus Luteus? Both s.luteus and s.brevipes are edible. Indeed, some of the boletes were more slimy than others. Probably that was the s.luteus growing in the wet areas and the s.brevipes growing in the dryer areas according to Mushroom Expert.com

  At Mushroom Observer participants share photos and descriptions to aid each other in identifying different species.

  About the mycorrhizal relationship:
  A mycorrhiza (Gk.,: fungus roots, pl mycorrhizae, mycorrhizas) is a symbiotic (generally mutualistic, but occasionally weakly pathogenic) association between a fungus and the roots of a plant.

  In a mycorrhizal association, the fungus colonizes the host plants’ roots, either intracellularly as in arbuscular mycorrhizal fungi (AMF), or extracellularly as in ectomycorrhizal fungi. They are an important component of soil life and soil chemistry.

  Mutualist Dynamics:
  Mycorrhizae form a mutualistic relationship with the roots of most plant species (and while only a small proportion of all species has been examined, 95% of these plant families are predominantly mycorrhizal).

  Sugar-Water/Mineral exchange:
  This mutualistic association provides the fungus with relatively constant and direct access to carbohydrates, such as glucose and sucrose supplied by the plant.[4] The carbohydrates are translocated from their source (usually leaves) to root tissue and on to fungal partners. In return, the plant gains the benefits of the mycelium’s higher absorbtive capacity for water and mineral nutrients (due to comparatively large surface area of mycelium:root ratio), thus improving the plant’s mineral absorption capabilities.[5]
  Plant roots alone may be incapable of taking up phosphate ions that are demineralized, for example, in soils with a basic pH. The mycelium of the mycorrhizal fungus can, however, access these phosphorus sources, and make them available to the plants they colonize.[6]
  

  Here’s a superb RANT about mushroom foraging and the exaggerated fear of poisoning

  Toxic Fungi of Western North America: poisoning guide

  PDF Guidelines for pot­hunters
  1. Learn the known toxic fungi first and the genera in which the major poisonings are found: Amanita, Lepiota, Galerina, Conocybe, Inocybe, Clitocybe, Paxillus, Hypholoma, Psilocybe, Cortinarius and Gyromitra.

  2. Eat new edible fungi in small amounts at first.

  3. Be cautious offering wild fungi to guests even if you have had no problems. Idiosyncratic GI reactions are common, although typical allergies such as hay fever, asthma and hives are uncommon. There are no reports to date of mushrooms causing allergic (anaphylactic) shock.

  4. Remember that many mushrooms cause trouble when eaten raw. These are usually GI upsets. Gyromitrin and some other toxins are destroyed, at least in part, by cooking. The Europeans have found that, on rare occasion, a number of common genera including “edible” amanitas are able to provoke red blood cell destruction when eaten raw or partly cooked. This should be true of all western hemisphere ?blushers? and of species referred to by the European name Amanita franchetii (Boud.) Fayod.

  5. Don’t be gluttonous. Small amounts of some toxins may be tolerated.

  6. If a canned mushroom has been ingested, call attention of physicians to botulism if there are pupil dilation, muscular weakness or central nervous system symptoms. There is an anti-serum available, which may keep victims off a respirator.

  7. Heed the advice of Elias Fries in his Observationes mycologicae, “Illustrations appeal to idlers who do not have energy enough to study
  descriptions”. Using a poor photograph of Agaricus augustus, but not reading the description below the colored plate, two California victims
  misidentified what was actually Amanita phalloides. Both required liver transplants.

3. very valuable information, thanks for hare. are the mushrooms can be eat ?

   Comment by yujiinha — January 21, 2010 @ 2:33

4. Hi Yujiinha,

   Yes, there are lots of wild mushrooms that can be eaten. It would be wise to find experienced mushroom foragers/collectors FROM YOUR IMMEDIATE AREA in order to find the edible ones and the spots where you can find them. It\’s really fun to go mushroom hunting with people that know the delicious species of mushroom, like a TREASURE HUNT!

   Until you become experienced, it is important that you find someone who is willing to share knowledge with you, so that you can later pass on this information to others.

   Please DO NOT use the images on this blog to identify edible mushrooms in Indonesia. There are different species all over the world, and with the help of an experienced mushroom forager and an up to date LOCAL field guide, you will quickly learn to discern some of the edible species growing around you.
