About This Reference
This page consolidates all clinical terminology used across every regional mushroom toxicology guide in the Spore & Scout library. The Master Clinical Glossary defines key toxins, clinical syndromes, and anatomical terms used in physician-facing documentation. The Universal ICU Discharge Criteria apply across all mushroom toxidrome types and represent the minimum threshold before a patient may be safely stepped down from the ICU or discharged. The Toxidrome Quick Reference Table provides a rapid cross-reference of onset windows and antidotes.
Data-only reference — no photographs. Species identification for clinical management must be confirmed by a toxicologist, mycologist, or poison control specialist, not from this text alone.

📖 Section 1 — Master Clinical Glossary
Amatoxins
A subset of highly destructive, cyclic octapeptides found in several mushroom genera (e.g., Amanita, Galerina, Lepiota). They are heat-stable, survival-resistant toxins that stop cellular transcription by selectively binding to RNA polymerase II, driving direct liver and kidney failure.
Atropinization
The clinical process of titrating intravenous Atropine doses until post-ganglionic parasympathetic overstimulation is successfully neutralized. Verified at the bedside by the drying of excess bronchial secretions, clearing of lung wheezing, and reversal of severe bradycardia.
Enterohepatic Recirculation
A physiological transport cycle where drugs or toxins are processed by the liver, excreted into the intestinal tract via bile, and then reabsorbed back through the intestinal walls into the portal bloodstream. This loop repeatedly exposes the liver to the toxin unless blocked with therapies like multi-dose activated charcoal.
Gyromitrin
A thermolabile hydrazine compound found in Gyromitra species (False Morels). Metabolized in vivo to monomethylhydrazine (MMH), which inhibits pyridoxine-dependent enzyme systems, causing hemolytic anemia, methemoglobinemia, and hepatotoxicity. Specific antidote: IV Pyridoxine (Vitamin B6).
Methemoglobinemia
A condition in which the iron in hemoglobin is oxidized from ferrous (Fe²⁺) to ferric (Fe³⁺) state, rendering it unable to carry oxygen. A complication of MMH toxicity. Treated with IV Methylene Blue 1–2 mg/kg.
Molybdophyllysin
A toxic metalloendopeptidase enzyme found inside the tissues of Chlorophyllum molybdites. It acts as a direct gastrointestinal cytotoxin, breaking down mucosal cell boundaries and triggering sudden projectile vomiting and secretory diarrhea.
Monomethylhydrazine (MMH)
The primary toxic metabolite of gyromitrin. Inhibits pyridoxal phosphate (Vitamin B6)-dependent enzymes, disrupting GABA synthesis and heme production, resulting in seizures, hemolysis, and hepatic injury.
Muscarine
A natural alkaloid compound that mimics acetylcholine by selectively binding to muscarinic acetylcholine receptors. It causes immediate, profound overstimulation of the parasympathetic nervous system (the SLUDGE toxidrome).
OATP1B3 (Organic Anion Transporting Polypeptide 1B3)
A key transporter protein located on the cellular membranes of human hepatocytes. It acts as the primary gate through which amatoxins enter liver cells; blocking this transporter with drugs like Silibinin helps prevent liver injury.
Orellanine
A bipyridyl nephrotoxin found in Cortinarius species (Webcaps). Causes delayed progressive tubular nephrotoxicity with onset 2 to 21 days post-ingestion — the longest latency window of any mushroom toxin. No specific antidote; management is supportive with nephrology and dialysis/transplant pathway.
Perforatorium
The distinct, hardened, or thickened center peak located on the top center of a mushroom cap. This feature is a classic anatomical marker used to identify certain native African edible species like Termitomyces.
Pseudorhiza
A long, root-like extension of a mushroom stem that burrows deep underground. It connects the visible mushroom fruiting body to an underground food source, such as a termite nest.
SLUDGE Syndrome
A clinical acronym used to describe systemic parasympathetic nervous system toxidromes: Salivation, Lacrimation, Urination, Defecation, Gastrointestinal cramping, and Emesis.
Trichothecene Mycotoxicosis
A severe, systemic poisoning caused by absorbing macrocyclic trichothecene compounds. These toxins bind to ribosomal subunits to halt protein synthesis, triggering tissue death, skin blistering, hair loss, and profound bone marrow failure.
🏥 Section 2 — Universal ICU Step-Down and Discharge Criteria
Applicable across all mushroom toxidrome types
Before a patient can be safely stepped down from the ICU or discharged following a toxic mushroom ingestion, they must meet ALL of the following clinical and laboratory criteria:
- 1 Hemodynamic Stability: The patient has maintained stable vital signs for a minimum of 24 consecutive hours without needing IV fluid boluses or blood pressure supports (vasopressors).
- 2 Gastrointestinal Resolution: Projectile vomiting and severe diarrhea have completely resolved; the patient can tolerate oral fluids and light meals for at least 18 hours without cramping or distress.
- 3 Liver Function Stabilization: Serial lab draws taken 6 hours apart show that serum transaminases (AST/ALT) have peaked and are steadily decreasing.
- 4 Clotting Function Normalization: Coagulation panels confirm that the PT/INR has stabilized below 1.5 without the use of fresh frozen plasma or clotting factor transfusions.
- 5 Renal Function Preservation: Serum creatinine and Blood Urea Nitrogen (BUN) levels have returned to normal baseline values, and spontaneous urine output remains above 1 mL/kg/hour without diuretic support.
- 6 Neurological Integrity: The patient matches baseline mental status with a Glasgow Coma Scale (GCS) score of 15. No signs of asterixis, confusion, or hepatic encephalopathy.
- 7 Confirmed Follow-Up Network: A mandatory outpatient lab appointment is booked for 48 to 72 hours post-discharge to check liver and kidney function panels, and the bilingual discharge template is fully signed, stamped, and handed to the patient.
