Fungi: Asomycota: Sordariomycetes: Xylariales: Xylariaceae: Xylaria: Xylaria polymorpha (Greville, 1824)

Contrary to its creepy common name, Dead man’s fingers, Xylaria polymorpha is an important fungus in the forest ecosystem with a black outer layer and white inside. This fungus is a saprotroph meaning they obtain energy from decaying matter and are seen from May to November. They break down dead material making nutrients accessible for other organisms consume. The name, Dead man’s fingers come from their odd, un-uniformly shaped fruiting bodies which resemble fingers poking out of the ground. They are widely distributed in deciduous forests of North America and Europe preferring to grow on apple, maple, locust and elm trees. Their scientific name literally means grows on trees (Xylaria) and many shapes (Polymorpha). They have an uncommonly long spore distribution period, allowing the fruiting bodies to persist for months and even years and spread very successfully. There is 1 representative on BOLD with barcode records. #Canada150 #Biodiversity150

Plantae: Spermatophyta: Angiospermae: Dicotyledonae: Gentianales: Asclepiadaceae: Asclepias: Asclepias syriaca (Blanco, 1837)

Asclepias syriaca or Common Milkweed is native to eastern North America and receives its name from the milky sap excreted from the stem and leaves when damaged. This full sun, drought tolerant plant blooms in early to mid-summer attracting a variety of insects including bumblebees, monarch butterflies and hummingbird moths.

Animalia: Mollusca: Bivalvia: Unionoida: Unionidae: Ambleminae: Quadrula: Quadrula quadrula (Rafinesque, 1820)

The Mapleleaf mussel is a freshwater mussel found in North America. Mapleleaf mussels are a threatened species in Ontario since 2008 and have completely disappeared from Lake Erie, Detroit and Niagara rivers. The main threats to this species are habitat destruction, invasive Zebra mussels from Europe and any conditions which threaten their host fish, the Channel Catfish.

62/150: I can live in the dirt or in your home, I hitch-hike on insects and mammals alike, and have venomous pincers. What am I?

Animalia: Arthropoda: Arachnida: Pseudoscorpiones: Neobisiidae: Microbisium: Microbisium parvulum (Banks,1895)

Pseudoscorpions are rarely seen but are common arachnids that resemble tiny scorpions with their two large pincers and 8 legs. Unlike scorpions, they are 3 mm in size with no stinger. Using venom glands located on the mobile finger of their pincers they prey upon booklice, ants, mites and small flies.
