With temperatures rising and the sun (kind of) shining, it would seem that spring has finally sprung!

There are many “ologies” in the world that relate to living organisms. Entomology, ornithology, mammalogy; the list goes on. One lesser-known discipline is mycology: the study of fungi.

On February 2, Punxsutawney Phil emerged from his burrow in a sunny Pennsylvania town. His prediction: six more weeks of cold fronts and snow flurries. Three weeks later and a thousand miles from Pennsylvania, groundhogs in the arboretum are at the tail end of a long winter spent below ground. …
