Populus tremuloides/Leccinum insigne [2]

 

She’d wet the tendrils of a foundling thirst

and pattern-knit each phantom synapse dimmed

to dirt, to darks of dreamless Mastodon,

— Mammut americanum

as, purling up the rot-swept sockets, she,

now eldest of a thousand sisters, split,

twinning out her virid tresses—past grief

grieving at the Pleistocene’s mouth. The Age

of Winter wasted toward an ocean,

a black vastness after landscape, a drum.

A comely aspen wood meanwhile began.

Selfsame sprung sister, sister, and sister.

At each insistent rise,

white-tongued fungus:

fibrillose, broad-capped, dullish and gill-girt,

– (10-15cm), convex to planoconvex

wide stipe blushing like a wine-bruised carpet.

– (2-2.5 cm at apex), clavate, solid

Mars to Prout’s brown in youth, velutinous;

late life, pileus tawny to russet.

Spores of like hue. Few to gregarious

– amber, ochraceous in Melzer’s reagent

in litterfall, aspen trash. Mild to taste

and tender-fleshed. Twining mycorrhizal:

– read: ecto

an easy, mutual thing—root music.

 

Down centuries of sisters, sweetly, she

struck fast and sang, the bubbling boletes come,

loosed of winter’s anchorage, a-bob, both

born of water, blessed of rot—shriveled soon

to soul-stuff, death-tethered specimens pruned

in a formaldehyde of borrowed words:

 

old codes swimming yet the cell’s soft cosmos

 

for all the rainfall’s sweet religion, gone.

 

She will go, too, the sisterhood in tow—

and I, with springtime and the mammoth, I

— Mammuthus columbi

who rummaged for a touch of lasting life,

prized of her native continuity,

of the bone-quiet communion of things;

divined in the glass-eyed microscope, I,

who inked this offering—who tongued the skull

for sheltering thought, sciences for sake of faith.


[2] In the arid American West, where climatic conditions have remained hostile to the establishment of aspen seedlings since the last glaciation, aspen often propagate by suckering—a process by which new trees are generated asexually from a network of buried roots; because an entire stand of aspen may comprise a single genetic individual, as old stems perish and new stems spring, the organism may enjoy a longevity of thousands of years. Aspen benefit from a host of mycorrhizal fungi species (among these, leccinum insigne). As the mycelium of an ectomycorrhizal fungus extends through the soil, it forms a mutualistic, extracellular association with the root systems of nearby trees, facilitating the trees’ uptake of phosphorous and nitrogen while feeding on plant carbohydrates, which it converts to fungal sugars.
