Domain Eukarya: The Mycena citricolor has a nucleus and other organelles so it is in the domain Eukarya.

Kingdom Fungi: All Fungi like the Mycena citricolor have a mycelium.

Basidiomycota examples. Wikepedia commonsPhylum Basidiomycota: Basidiomycetes have dikayrotic hyphae which means they have a haploid nucleus from both parents.  Mycena citricolor have dikayrotic hyphae and are therefore placed in this phyla (EOL 2013).  Auricularia auricula-judae is another basidiomycete that has medical research value.

Class Agaricomycota:  The Agaricomycotina are the fungi are the mushroom forming fungi.  The Mycena citricolor forms mushrooms and is therefore is placed in this class (EOL 2013).  Another agarimycete is the Trametes versicolor.  This fungus is called the "Turkey Tail" and is a mushroom in the same class as the Mycena citricolor that is edible and used for medicines unlike the Mycena citricolor.

Order Agaricales: This order holds all of the parasitic fungi.  The Mycena citricolor is a parasitic fungus which is why it is placed the order Agaricales.  These fungi are also all gilled mushroooms. (EOL 2013).  Another example of an agaricales is the Pleurotus streatus, or the "Pearl Oyster Mushroom". This is an edible gilled mushroom that is commonly found on decaying trees and plants.Example of a Fungus from the Mycenaceae family. Wikepedia

Family Mycenaceae: The Mycenaceae fungi are saporbic fungi.  The Mycena citricolor is a saporbic fungus which is why it is in this family (EOL 2013).

Genus Mycena: The Mycena fungi have are only a few centimeters in width and have a small bell shaped cap.  The Mycena citricolor is very small and has this small bell shaped cap which is why it is in this genus (EOL 2013).

Species Mycena citricolor: The Mycena citricolor is the parasite that is responsible for the lesions and premature leaf abscission on the coffee plants (Rodrigues, C.J., Arney, Dean).

Phylogeny of Major Clades. Permission Dr. Sanderfoot

Figure 1. This is a proposed hypothesis of a phylogenetic tree of the order Agaricales.  The tree was hypothesized by the similarities in the fungi's rRNA.  The Mycena citricolor is located in the bottom of this phylogeny in the family Mycenaceae.
