Fungal Word Friday: Sporangium


Spores are formed and spread a variety of ways. an enclosure in which they are formed is called a sporangium.... Its greek origin literally means Spore vessel.
A sporangium can be just a single cell or it can be made up of multiple cells. In some species of fungi can even be one of the most noticeable parts of its fruiting body.

Fungal Word Friday: Spore

So here we are, about a year and a half since the first fungal word Friday and I have not thought to one of the most well known fungal words; spore. I rectify that today!

A spore is the reproductive cell of fungi. It can be unicellular or multicellular and formed through either meiosis or mitosis. Spores in fungi are so diverse that they can be used as an identifier of fungi for several groupings in the Kingdom.

Fusarium spores

Amanita muscaria spores

 As you can see from just these four randomly selected fungal spore pictures, they come in a vast array of sizes, shapes, colors, and packaging. Spores, while used for reproduction and dispersal are a complex part of what we all know is the complex life of a fungus.

Fungal Word Friday: Phialide

A phialide is an elongated and flask shaped (where it gets its name) projection rising from the vesicle in certain fungal groups, such as Aspergillus.

Phialides extend out of the mycelium and serve as the basal cell for increasing chains of conidia

First Mushroom Monday: Parrot Waxcap

The parrot waxcap, Hygrocybe psittacina, is a small and colorful mycorrhizal mushroom found in northern latitudes. It fruits in late summer and into autumn with a green umbonate cap that gains a yellow or pink tinge as it ages. The stipe of the parrot waxcap is a greenish yellow and the gills are green with yellow trim. The mushroom is only about 1-2 inches tall with a cap that only gets up to about 1 inch in diameter.

Despite it's small size and coating of a mucus-like substance, it is still considered by many as edible.
