Northland Nature: Rain causes ‘shroom boom’


Late September is a superb time to see the colourful leaves within the Northland forests. As I stroll on the street, passing the woods, I see lots, even with the dryness this yr. Reds are extra frequent in sunny websites (apparently, the crimson pigment of anthocyanin acts as a “sunscreen” throughout the leaves). I see shiny ones on crimson maples, sumacs, dogwoods, pin cherries, American hazels and younger crimson oaks.

Yellows outnumber the reds and so they shine on birches, aspens, basswoods, sugar maples, beaked hazels and ashes. These black ashes of the swamps aren’t often credited for colours of fall, however immediately their glow abounds.

As I step away from the street and stroll on the paths of the woods, I’m handled to a different delight of September: the range and abundance of mushrooms and different fungi. Until not too long ago, September has been dry, however responding to precipitation has precipitated a little bit of a “‘shroom increase.” The many mushrooms listed here are of two varieties.

Most mushrooms rise up from the substrate (floor or logs) with a stem that holds a cap on prime. Under the cap are many lined buildings known as gills. This is the place the spores are discovered.

Other mushrooms, additionally frequent right now, are with a stem (stalk) with a cap, however as a substitute of gills under the cap, they’ve quite a few tiny holes known as pores that maintain spores. These porous mushrooms are collectively known as boletes. This woods stroll reveals me many gilled and porous mushrooms in addition to non-mushroom fungi.


Among the gilled mushrooms, I discover russula, with caps of crimson, yellow, brown and white. I additionally discover milk mushrooms (Lactarius) and shiny crimson waxy caps (Hygrocybe) on the bottom and tiny mycena and clusters of scaly-caps (Pholiota) on logs. With gills, however with out stems are massive growths of Pleurotus (oysters) scattered on logs and tree trunks.
