Four hours later, sitting in the private room on the top floor of the restaurant in the Tang and Song Dynasties, everyone talked and laughed.

Although Liu Xuzhi wholeheartedly wanted to go back and recall the operation, compared with refusing boss Zheng's invitation, he still came to dinner.

Song Ying sat beside Zheng Ren, chatting simply and gossip.

His speech is neither light nor heavy, nor slow, which makes people feel very comfortable.

"There are some fresh mushrooms these days. They were transported from Yunnan. Please boss Zheng to try them."

When the lobby manager opened the door and the waiter rushed in with dishes, song Yingcai introduced it.

Zheng Ren smiles.

But he obviously felt that the little hand he held seemed a little tight. It seemed that the little Iraqi liked it.

"There are many kinds of mushrooms in Yunnan. It is said that they are very fresh and delicious. Brother song is interested." Zheng Ren felt that Xiao Yi liked it and was naturally happy. It was a rare compliment.

"There are too many kinds of mushrooms in Yunnan. Many people in Yunnan eat poisonous mushrooms and are about to eat them." Song Ying smiled and began to gossip.

"Ah? Can poisonous mushrooms be eaten?" Chang Yue was surprised.

"Look at your inexperience." Su Yun denounced: "the most common poisonous mushroom in Yunnan is called jianshouqing. After eating, you can see hallucinations."

"..." Chang Yue stroked his glasses and felt that the mushrooms in front of him seemed to be toxic.

"Xiao Chang, don't be afraid. The mushrooms we eat must be non-toxic." Song Ying began to invite everyone to dinner and undertook the obligation of explanation.

Because most of the mushrooms eaten in the imperial capital are apricot abalone mushrooms, golden needle mill and Tricholoma. Many varieties of mushrooms come up today, not to mention Chang Yue, even Lin Jiaojiao has never seen them.

What are the origins and how delicious are the light green fungus to the dark green fungus.

How delicious white, yellow and black Boletus is and why it is one of the four bacterial kings.

Why is the black brown and beef jerky dry fungus a local specialty in Yunnan.

Why is the pure wild Dictyophora Zhijin called the queen of fungi.

Song Ying's speech was humorous, knowledgeable and not boring. Everyone listened with interest and ate soundly.

But Chang Yue still remembers the poisonous mushrooms. After drinking a bottle of iron covered Maotai, Chang Yue whispered to Su Yun, "why do Yunnan people eat poisonous mushrooms?"

"Because it's delicious." Su Yun drank the wine in the cup and aftertasted it for a few seconds before he continued: "my classmate worked in Yunnan. He said that 70% of the people who went to the emergency department for gastric lavage that night ate poisonous mushrooms and 25% drank too much."

"Er..." Chang Yue still didn't understand why she had to eat poisonous mushrooms.

"They call eating mushroom poisoning seeing villains. Many of the beds in the digestive department are poisoned by mushrooms. They are not afraid. What is eating mushrooms seeing villains? Just eat some mushrooms later!"

"I remember a kind of hallucinogenic mushroom. Is that it?" Chang Yue asked.

"It should be different. Hallucinogenic mushrooms are prohibited in our country. Seeing green hands is just an ordinary poisonous mushroom, but it is not toxic and difficult to die." Zheng Ren said.

"Isn't that similar?"

"In 2006, a study by Johns Hopkins University found that humans will have ecstatic hallucinations after ingesting the active ingredient of hallucinogenic mushrooms, naked mushroom." Zheng Rendao.

"I haven't studied it carefully, but it should be different." Su Yun added: "hallucinogenic mushrooms contain hallucinogenic substances such as dimethyl-4-hydroxytryptamine phosphate and dimethyl-4-hydroxytryptamine, and occasionally contain some other tryptamine substances with mental effects.

There are many popular names for hallucinogenic mushrooms. The most common is magic mushroom or death mushroom. "

"Jianshouqing" is the general name of a kind of Boletus with the characteristics of indigo color reaction after injury. It has a large number of species and belongs to Boletaceae.

Most of them belong to Boletus, and there are other genera. Boletus flavipectus, Boletus velutipes, Boletus powder, Boletus orange. "

"It's so complicated." Zheng Ren said: "see hand green is just a general term. Some mushrooms are poisonous, and most of them are not poisonous. In short, see hand green usually refers to several Boletus with certain color, characteristics of see hand green and long cooking history in Yunnan Province."

"It's dangerous, too." Chang Yue said.

"If it's dangerous, don't eat it? What is puffer fish? I don't have the spirit to eat goods at all." Su Yun said contemptuously, "look at the little Iraqi. How many mushrooms did she eat when you spoke."

Zheng Ren glanced at Xie Yi.

Face dividends, a few sweat hanging on the tip of the nose, is eating happily.

What's poisonous? It seems that little Yi won't care at all.

"Hallucinogenic mushrooms are legal in the Netherlands. If you have a chance to go to the Netherlands in the future, just be careful. But it's easy to identify. You can know at a glance." Su Yun said, "I tell you, don't be curious about eating that thing. Although it's not addictive, this curiosity is terrible."

"I want you to say." Chang Yue glanced at him and said with disdain.

"The coffee shop or smart shop on Amsterdam street can be bought for ten to twenty euros. It looks a little like cashew nuts, but tastes sour and smelly. It takes 4-6 hours." Su Yun said: "after eating, you will be thirsty and have hallucinations."

"It's like you've eaten." Chang Yue said with disdain.

"Doctor Chang, there's something called a book. Now it's an internet society. Just look at the fragments of knowledge." Su Yun poured the wine for her, picked up the glass and touched it. He drank it himself.

"It's not delicious. Don't eat casually. What you eat is mainly delicious and delicious."

"Mushrooms are all fungi."

"Fungi of mushroom family and mushroom genus." Zheng Ren said with certainty.

"Don't underestimate mushrooms. If they can grow vigorously, they can grow very big." Su yundao.

"How big can it be?"

"In 1998, a strain of Armillaria olgensis was found in mahur National Park, Oregon. Its bacterial cord, like a pipe with a diameter of 2-5mm, has quietly extended underground for 2400 years, and the territory has expanded to 14400 mu." Su Yun explained.

Millions of square meters... Chang Yue thought, some stunned.

"Is it possible? How did you find it?" Chang Yue asked suspiciously, "dig a little?"

"Americans dig and sample in different places, and then conduct genetic testing and Analysis on the hyphae obtained at different sampling points to confirm that the hyphae distributed underground within about 965 hectares belong to the same individual." Zheng Rendao.

After a few mouthfuls, he was full and began to gossip. Zheng Ren also wanted to see the giant mushrooms with his own eyes.

"According to speculation, there should be about 600 tons of this big mushroom, enough for us to eat for a year."
