Entolomatoid Mushrooms
Late summer and fall may be peak mushroom seasons on PEI, but spring has fungi to find, too! While checking my go-to spots for Morels this week, I found lots of these Entolomatoid Mushrooms (Family Entolomataceae). I often ignore LBMs (little brown mushrooms) as being too hard to identify and above my skill level. However, as I gain experience in mushroom identification, I’ve started looking for clues that point to the Family. If you’ve attended any of my workshops, you’ll

Black Knot Fungus
This is a great time of year to spot a PEI fungust that's best known as a disease of Cherry trees: Black Knot ( Apiosporina morbosa ).

But Lung Lichen is one PEI’s few tripartite lichens: it includes a fungus, a green alga, and a cyanobacter

Sunburst Lichen
The Island’s winter landscape is mostly monochrome, making the occasional burst of colour all that more beautiful. One of my favourite bright spots is the aptly-named Maritime Sunburst Lichen ( Xanthoria parietina ). Lichens are interesting in many ways, including how they survive our coldest months. Most living things go to great lengths to protect themselves from drying out or freezing: two major (and usually lethal) side effects of winter. That’s why PEI’s trees, plants, f
