Stubble Rosegill Journal entry

Volvopluteus gloiocephalus is a species of mushroom in the family Pluteaceae. The mushroom is more commonly known as stubble rosegill. The Stubble Rosegill is fairly common in Ireland and Britain, and often seen in fields that have been harvested of a grain crop. The mushroom is safe to be consumed, however, it is not recommended since it can be confused with deadly Amanita species which have similar appearance as the Stubble Rosegill.

Journal of fungi Xylaria polymorpha

Xylaria polymorpha, which is commonly known as dead man ‘fingers is a saprobic fungus. It appears in palmate bunches, finger-like stromata. The asci in the black coating flask are used to produce its spores, therefor also known as ‘flask fungi’. It is a common species in Britain and Ireland, also in Europe and parts on North America. It usually lives in moist woods habitat, growing from the rotten trees’ stumps or woods. Dead Man’s fingers is not usually considered to be edible. Ethanolic extracts from the Xylaria polymorpha can have antimicrobial potential against the bacteria and yeast structures by inhibiting the cells growth of bacteria.

Michael Yang - Journal entry

Maple trees have a number of adaptations to ensure their survival. Maples trees have broad leaves so they could capture the maximum amount of sunlight for photosynthesis. They lose these leaves in winter to cut down on the water loss. Their leaves also contain many nutrients like calcium, potassium, phosphorus, and nitrogen that can be reabsorbed later for the tree to use again.

Peng Min--Observation of Spruce

One of the significant features of spruce is their needle leaves. This is an adaptation for them to have a better fitness in the northern temperate and boreal climate in order to survive. Evergreen needle reducing the surface area prevents them from further water-loss by transpiration. By genetic analysis, genus Picea originated from North America.
Trees I observed share in common that they all have well-developed root system. This also helps them to gain more water and nutrients.

Meg's Journal Entry

Birch trees have numerous adaptations to help them survive in different environments. One such adaptation is that they loose their leaves in the winter in order to minimize water loss. An adaptation shared by all the trees I observe is that they have adapted to the irregular drainage conditions of Montréal which come as a result of varying soil textures, types, and structures. The Quercus Robur is placed far down on the phylogeny tree. Its most recent common ancestors are the Bur Oak, Oregon White Oak, and Blue Oak. This makes sense because the Quercus Robur is a type of oak tree.
