Lab 5 Fungi Journal Entry

The Fungi that I chose to focus on from this weeks observations is the False Death-Cap, also known as Amanita Citrina. The False Death-cap is a mycorrhizal mushroom that tends to grow with deciduous or coniferous trees and favors neutral or slightly alkaline soil. The mushrooms begin growing in a sac called the volva or universal veil and dirty white colored fragments of this are visible on the cap of the fruiting body. The rest of the fruiting body is white with a yellow tinge. It is not a species that is used by humans for food or for medicinal purposes but it is important for some fly species, slugs, snails, and some small mammals who use it as food. Although the False Death-Cap is classified as inedible or mildly toxic, it can easily be confused with Death-Caps which are deadly if ingested.

Lab 2 Journal Entry

I chose to look at the phylogeny for the Eastern Hemlock or Tsuga canadensis. It is a species of Hemlock, is part of the family Pinaceae, is an Acrogymnosperm, and more generally a vascular seed plant. One adaptation that the European Raspberry( Rubus Idaeus) has is thorns on its stems. This adaptation helps to prevent herbivores from eating the plant. If the plant is not eaten, the plant can produce berries with seeds and can reproduce/spread faster. Since all of my observed plants are vascular plants, an adaptation they have in common is xylem and phloem cells. These help conduct water and solutes through the plant.
