Medicinal Mushrooms: Tinder Conk

A frequent destination of mine, as of late, is a wooded trail near my home with a generous quantity of tough tree fungi.  One such fungus is Tinder Conk (Fomes fomentarius), a light-colored, hoof-shaped species who I found growing on a Gray Birch (Betula populifolia) tree.

Tinder Conk is a perennial fungus, capable of living for several years if the woody food source allows.  According to Greg Marley*, Tinder Conk tends to be smaller on Gray and Paper Birch (B. papyrifera), species who decay rather quickly, and can be longer-lived (and larger) when growing on Silver Birch (B. alleghaniensis), American Beech (Fagus grandifolia), and Maples (Acer spp.).  That said, Tinder Conk appears best camouflaged when growing on Paper Birch (bottom photo).  To my eyes, the tree and fungus appear meant for each other.

The underside of Tinder Conk is slightly concave and covered with tiny pore openings.  It is from these holes that spores are released during periods of active growth.  For foragers interested in gathering Tinder Conk for medicine, Greg Marley advises collecting "conks only when they are actively growing and producing spores; in the northeast, that is from June through October."  The pore surface, he writes, "should look fresh and evenly buff-tan."  So, get to know where this species grows now and return in the summer for prime collection.

Perhaps the most famous use of this shelf fungus is as... Tinder!  While I can't speak from experience (though I just added it to my to-try list), I've read that Fomes fomentarius is a superb natural material for catching sparks and creating a smouldering coal.

*To learn more about the medicinal and folk uses of Tinder Conk, I'd recommend Greg Marley's book Mushrooms for Health: Medicinal Secrets of Northeastern Fungi (2009, pages 120-124).

Foraging Wild Fruit: Staghorn Sumac

From a distance, today's plant has a definite resemblance to that of Smooth Sumac, who I profiled back in August, when I lived in Massachusetts.  Here in Maine, I more frequently encounter the fuzzy stemmed Staghorn Sumac (Rhus hirta).  As I've described previously, the red fruit clusters of either species can be used to make a pleasant drink.

What I didn't share before is that both shrubs (or small trees) have known medicinal uses (including using branchlets as mouth-cleaning chew sticks), and both have wood that can be used to make friction fire sets.  For more on these uses and others, check out Ancestral Plants by Arthur Haines (2010).

Foraging Wild Fruit: Hawthorn

I enjoy looking closely at details to nail down a positive species-level identification (see my Aster ID post), but sometimes specificity is best left to professional botanists.  According to GoBotany, the Hawthorns (genus Crataegus) comprise "the second largest number of species of any genus of vascular plants in New England" with nearly 50 difficult-to-differentiate kinds. Luckily, sorting them out to the species level is not required to forage them responsibly -- according to Arthur Haines, "their uses are similar (though some species have larger flowers and fruits than others)."*

Prior to this fall, I hadn't encountered many fruit-filled hawthorns, but I happened to notice this planted tree outside the library where I work.  The young leaves, along with the flowers and fruit, are said to be edible and high in antioxidants.  Hawthorns are also well-known heart tonics. The only way I've tried this plant, aside from a few raw fruits, is as an alcohol extraction of purchased dried fruit.  Herbalist Deb Soule of Avena Botanicals shares more about the gifts of Hawthorn in the video below.

Medicinal Weeds: Red Clover

With alternate, divided leaves and clusters of irregularly shaped flowers, using Newcomb's Wildflower Guide, we shouldn't be surprised to find this plant on the same page where we found White Clover two weeks ago. Of the three other Trifoliums listed on page 60, we find the plant that matches: Red Clover (T. pratense) – a plant with flower clusters that appear stalkless and leaves which often show prominent white chevrons.

Red Clover blossoms (or entire tops as pictured above) make an excellent wild tea. Herbalist-author Gregory Tilford says Red Clover is “an herb that helps free the blood of toxins and systematic waste while providing an assortment of nutrients critical to healthy blood” (From Earth to Herbalist, p. 174). In short, he describes the plant as a “medicinal food”.  Only fresh or properly dried material should be used, as wilted Red Clover can mold and contain harmful toxins.  Of course, it is critical to do your own research and come to your own confident conclusion regarding identification, proper preparation and personal health considerations prior to consuming any wild plant.

Gathering Pine Pollen Cones — Part 2

This spring, I've been monitoring a stand of Pitch Pine (Pinus rigida) near my home, and when I checked the trees on mid-day Tuesday, I found nearly all the pollen cones at the perfect stage for gathering -- almost open.  A couple days later and much of the pollen would have literally blown away.

As with the cones I gathered last year*, I've tinctured some and frozen the rest to add to meals in the coming months.  If you've never tasted a pine pollen cone, now just might be your chance.  Look for them on the light-green, growing branch tips, and be sure to sample cones before they open, release their pollen, and dry up.

If you can't wait until the next wild crop, you can order both pine pollen and pine pollen tinctures from SurThrival.

*Those were from Eastern White Pine (Pinus strobus).  The pollen cones of Pitch Pine are larger and therefore quicker to gather in quantity, and (at least this year) P. rigida cones are ready earlier than P. strobus.
