Mushrooms


If you find mushrooms disturbing, here is your warning to not read on! If you find them intriguing like myself, let's dive in. The study of fungi is called Mycology, and this branch of science is often housed in university botany departments. As recently as the 1970s mushrooms were actually classified as plants. There are possibly millions of species; many exist under the soil surface out of sight. Many species help support plant life through symbiotic relationships and enhance plant to plant communication. The mushrooms of culinary interest are just a fraction of species. With all the recent rain, many mushrooms have been “fruiting” and we have received many client calls curious of what types they are seeing. Today, I will show a few examples of recent requests and discuss various identification techniques. 

Disclosure: Unknown mushrooms should never be consumed, including those presented today. It can be a deadly mistake. Instead, snap a picture or bring us a sample. Samples identified by our office can be confirmed for safe eating (or not!). Species cannot be confirmed by pictures but educated guesses are provided. If you need support identifying a specimen please email me photo(s) and or call our office at 910 576 6011, I’d be happy to assist!

Our first mushroom is the blusher, Aminata rubescens. This mushroom grows in association with tree roots, a symbiotic relationship. It is a gilled mushroom appearing white to gray, with pale flecks on the top of the cap. One characteristic that can be helpful in identifying mushrooms is how they stain or bruise. For instance, the blusher turns slowly red upon handling or bruising.

Our second species is a stunning beautiful clavaria, or yellow tipped coral, Ramaria formosa. Pictured below it appears salmon to white, which is characteristic of this species. It is found throughout North America. Not much is known about this mushroom, but it may form associations with trees. Notably it lacks gills seen in other mushrooms. This is another identification characteristic - some mushroom undersides have gills, others have pores, scales, are smooth, are spongy, or even have teeth like structures.

One great way to identify mushrooms at home is to do a spore print. These prints can even be artistic, as spore prints are often colorful and abstract. However, these colors and shapes often tell you about the specific mushroom. To do a spore print, remove the cap from a mushroom and place it gill side down on a dark sheet of paper. Set in a warm dry location for 48 hours. After this time, remove the cap and observe the result. See below for some examples. Spore colors can be any color, ranging from brown to bright pink.

Our third species of the day is the smooth chanterelle, Cantharellus lateritius. Chanterelles look like they have gills, but these are actually characteristic false gills called rugae. There are many different chanterelle species and they are highly valued fresh and dried. Remember - never consume without properly identifying the species by calling our office.

Finally, not all mushrooms are identifiable by morphology and require laboratory testing. Mycology is a growing field and new species are identified constantly. The bright orange mushrooms below are part of the bitter bolete family, genus Tylopilus. The species is uncertain. All boletes lack gills, and many bruise a distinctive color when cut or bruised.
