Mushrooms in the Desert? I Have Pictures!

Living in the Sonoran Desert, I don’t often see mushrooms.  Sometimes, fungus appears on the trunks of dying trees, but that’s not often. This year, Tucson has had a very wet monsoon season, which is wonderful after years of severe drought.

Along with the greening of the vegetation, the abundance of rain has brought forth some interesting mushrooms.

These interesting mushrooms are Podaxis pistillaris, the Desert Shaggy Mane mushroom. Possibly the most common mushroom in the Sonoran Desert, this genus of fungus, possibly this species, is found in deserts worldwide. The above ground portion, the fruiting body, appears after a soaking rain. The fibrous texture and closed cap are believed to protect the gills and spores from desiccation.

The mushroom starts out whitish, turns brown, eventually ends up as black powder.

Being unfamiliar with this type of mushroom, I was curious to see what happened to these specimens. Would they be consumed by rodents, rabbits or coyotes? Would the horses be interested in eating them?  No, these mushrooms were undisturbed. This made me think this fungus is toxic.  However, P. pistillaris, is eaten in many areas of the world and has high nutritional value.

In addition, this mushroom is used extensively in traditional medicines and cosmeceuticals throughout the world. Now, I’m intrigued to try this mushroom, but I’ll await instruction by an experienced mushroom hunter.

I’m always delighted when I discover new and different aspects of the Sonoran Desert.

Ergot: A Fungus and a Tissue Protuberance–Geez!

My favorite bread flavor is rye. Given a choice, I will always choose rye.  So, growing up, I wondered why rye hadn’t been more popular historically. After all, rye is easier to grow than wheat and, in my humble opinion, much tastier.

The reason is Ergot.  Ergot is a fungal disease that killed and disabled people throughout Europe. Symptoms produced by the fungus Claviceps purpurea include gangrene, convulsions, headaches and hallucinations. Healthy grains are replaced with dark, hard ergots and get mixed into the flour during harvesting and milling.

Once the source of the ergot was identified, the infections were able to be controlled. An interesting story in history.

photo ergot protuberance on horse fetlockI love learning about words and, as a new horse owner, I got a word-surprise one day. I get lots of advice from more experienced horse people. One of the recommendations I’ve gotten is to keep the tissue protuberances on the legs trimmed. These natural calluses are made of keratin that can flake off. They are hidden in the long hairs just above a horse’s hooves. My gelding’s flake off nicely by themselves, but I need to soften the tissue on my mare so I can pull them off.

Why am I telling you this? Because these protuberances on the horse’s fetlocks are also called Ergots. (Their purpose is not known.) The fetlock is sort of the ankle of a horse. Ergot is derived from the French word for a rooster’s spur, which makes sense, since that is what it looks like.

Ergot: one word, two very different meanings: A fungal disease or a protuberance on a horse’s fetlock.

Bonus Word: Higher up the horse leg is a round callus that also flakes off or can be trimmed flat. This is called a chestnut. That’s a word with three meanings:

A tree that produces an edible nut;
A reddish-brown colored horse with a brown mane and tail;
A callus on the inner side of a horse’s leg.

Book Note: I’ve recently released a new book, Squirrels of the Sonoran Desert. Did you know that every squirrel in this desert is a ground squirrel? Neither did I until I did my research. There are lots of fun science facts in this book, written in rhyme. You can see it on the Sonoran Desert books page.

book cover for Squirrels of the Sonoran Desert
Despite their different appearances, all the squirrels native to the Sonoran Desert are ground squirrels! Burrow into this book to learn about their shared and unique features. This is a great family read for ages 5 and up. If your little ones are curious about those borrowing, furry squirrels in your backyard or at your favorite park this book is a great introduction. It’s full of insightful information and wonderful illustrations. Even if younger children won’t remember all of the scientific knowledge contained in this book, it’s important to start imprinting their brains with positive, educational, interesting information about the world around them.
