Key characteristics and habitat

Symptoms of toxicity, such as abdominal pain, vomiting, and nausea, usually appear around 6-12 hours after consumption, which makes it even more dangerous. When not treated quickly and properly, amanitin toxin can cause death.

Mushroom poisoning first aid kit

As we have discussed with Amanita species, there is no antidote for amanitin toxin. However, you can take first aid measures by washing your mouth to remove the remaining mushrooms. 

In addition, keeping the body hydrated, especially when symptoms of diarrhea and vomiting appear, is vital. Meanwhile, you must immediately contact medical assistance or go to the emergency room when you realize you have consumed toxic mushrooms or when the early symptoms appear.

The Danger of Misidentification

After you broaden your insight about Texas forest mushroom varieties in the previous section with each toxicity, let’s move on to the consequences of missing identifying these fungi.

We understand that it can sometimes be challenging to differentiate edible vs poisonous mushrooms in Texas due to their resemblance. Take False Morels as an example.

Many people think False Morels are delicious edibles, yet that’s not the case. Instead, True Morels are one of the edible mushrooms in Texas that you can find on forest floors. People often mistakenly think the two are the same because their shape, size, and physical appearance are similar.

The Danger of Misidentification
The Danger of Misidentification

One case of False Morel poisoning was reported in an Asian couple who experienced vomiting and stomach upset after consuming the fungus. They also developed mild hepatotoxicity, but luckily, they recovered.

Another case of mushroom poisoning occurred in Australia. This case ended with unfortunate events where 3 people died, and one needed a liver transplant.

This happened after they had lunch together at the house of one of the family members who apparently cooked wild mushrooms he picked. The shocking news is that mushrooms turned out to be Death Caps, one of the amanita species found commonly in Texas.

As with False Morels, there is a possibility that the woman who cooked Death Caps thought these mushrooms were puffballs or paddy-straw fungi, which are edible ones. However, this case is still under investigation.

Seeing this news, toxic mushroom prevention and safety have become increasingly crucial. If you are not sure about the mushrooms in Texas forests you have found, you are better off leaving them and looking for a field guide to Texas fungi from the mycology community. 

Poisonous Mushroom Cases in Texas

As we briefly mentioned before, Eastern Texas is home to local Texas mushrooms, with over 200 wild Texas mushroom species spread across the region.

Despite the abundance of wild fungi in Texas, only a few cases of poisoning have been reported. According to a 2006 study, the most common toxic fungus exposure in Texas comes from Psilocybin, and only a small number of poisonings occur due to Amanita mushrooms in Texas.

Poisonous Mushroom Cases in Texas

Luckily, we managed to find an example of a case mentioned in a 2012 journal. A 64-year-old woman of Chinese descent showed symptoms of mushroom poisoning by complaining of nausea and vomiting 10-12 times.

The woman also experienced abdominal pain and 6-8 episodes of non-bloody, watery diarrhea. Apparently, it was discovered later that the woman and her husband picked wild mushrooms from a sidewalk near Houston, Texas. Because the symptoms were getting worse, they were admitted to the hospital.

With the help of the poison control and mushrooms organization in Texas, medical staff can find out that the mushrooms consumed by the patient were Amanita species. After further examination and treatment, it turned out that his liver had suffered acute damage due to Amanita’s toxins. Fortunately, the woman and her husband survived because of fast treatment.

Considering the extent of toxic mushroom effects, it is crucial to step your feet into

Seasons That Poisonous Mushrooms Commonly Found

Like fruits and vegetables, both edible and poisonous mushrooms in Texas also have specific conditions for them to flourish. They like moist, wet, but cool conditions to thrive and spread their spores.

Hence, spring and fall are the two main seasons that are preferable because they meet their growing conditions. In spring, mushroom hunting in Texas starts the game. Generally, the foragers will start exploring city forests, national parks, or nearby parks to harvest edible wild mushrooms.

While the edibles are ready to pick, deadly mushrooms in Texas, such as Amanita phalloides (Death Cap), are also ripe. This is where the dangers of Texas foraging lurk, especially if you have no knowledge about mycotoxins in Texas.

Since Death Cap has a similar appearance to Paddy Stray and Puffball mushrooms, the awareness of how to identify the seasonal toxic mushrooms is critical. Mushroom enthusiasts must stay alert in foraging and practicing mushroom safety in Texas.

Besides spring, fall is another long-awaited season for mushroom foray in Texas. True Morel and Chaterells are two examples of edible mushrooms in Texas forests that are favorites for foragers to pick. Unfortunately, they have a look-alike to one of the most dangerous mushrooms in Texas, the False Morel.

FAQ (Frequently Asked Questions)

Do all poisonous mushrooms in Texas have a distinct look or taste?

Unfortunately, not all poisonous mushrooms in Texas boast similar appearance or flavor to distinguish themselves from edible ones. Some of them, like False Morel and Amanita species, closely resemble True Morel and Puffball mushrooms, respectively. Besides, they also feature pleasant taste. No wonder they are among the common ones that cause mushroom poisoning. 

How long does it take to know if you ate a poisonous mushroom?

It’s hard to tell at a specific time to tell whether you ate a poisonous mushroom since each one shows different symptoms in a diverse range. But generally speaking, you will notice poisoning signs around a few hours to 12 hours after ingesting the toxic mushroom. When you notice symptoms like nausea, vomiting, diarrhea, or gastrointestinal distress, seek immediate help from medical professionals. 

Are there specific regions in Texas known for a higher prevalence of toxic mushrooms?

Considering the diverse Texas climate, certain regions in Texas, such as Eastern and Northeastern, have wet and cool conditions that are preferable for mushrooms to grow, including the Texas toxic fungi. These areas have a high prevalence of rainfall, thus aiding in higher humidity. 

If you live within the region, you may expect common backyard poisonous mushrooms in Texas, for example, False Morel or Death Cap, around your outdoor space. And suppose you have pets. In that case, protecting pets from toxic mushrooms is vital. You can remove those fungi and ditch them before your beloved dogs or cats curiously devour those culprits. 

Has there been a recent increase in mushroom poisoning cases in Texas?

We can say that, fortunately, there’s a lack of sudden increase in mushroom poisoning cases within Texas. It’s because only Eastern and Northeastern regions are suitable for toxic fungi to grow. We also assume that the cases may not be reported to the authorities. Contrarily, the states that commonly report issues regarding poisonous mushroom exposure are California and Oregon.

Are animals, like dogs or cattle, also at risk of poisoning from Texas mushrooms?

Not only humans but animals like dogs or cattle are also at risk of mushroom poisoning in Texas. For dogs, they may be curiously devouring toxic mushrooms that grow in your backyard. Meanwhile, cattle will likely get the exposure from grazing or exploring the grass. Therefore, it’s extremely important to take care of your pets and animals to prevent access to wild mushrooms that can potentially put their lives at risk.
