| Common Name | Scientific Name | Tier | Toxin | Onset | Primary Risk |
|---|---|---|---|---|---|
| Deadly Webcap | Cortinarius rubellus | Tier 1 | Orellanine | 3–14 days | Acute interstitial nephritis, irreversible renal failure |
| Fool’s Webcap | Cortinarius orellanus | Tier 1 | Orellanine | 3–21 days | Acute interstitial nephritis, progressive renal failure |
| Funeral Bell | Galerina marginata | Tier 1 | Alpha-amanitin | 6–24 hours | Fulminant hepatic necrosis, coagulopathy, multiorgan failure |
Orellanine-Bearing & Amatoxin-Bearing Species
Cortinarius species carry orellanine with a catastrophically delayed onset of 3–21 days, often decoupling the ingestion event from clinical presentation. Galerina marginata carries alpha-amanitin identical to Death Cap. All three species are lethal without prompt specialist intervention.

Orellanine Nephrotoxicity Toxidrome (Cortinarius rubellus / orellanus — combined)
- Initial Phase (0–72 hours): Asymptomatic or mild, transient gastrointestinal distress (nausea, emesis)
- Delayed Renal Phase (3–21 days): Intense, unquenchable thirst (polydipsia), severe flank or lumbar pain, chills, intractable headache, profound fatigue. Progresses from polyuria to progressive oliguria, culminating in complete anuria secondary to acute interstitial nephritis and acute tubular necrosis.
- Antidote Availability: No specific or validated antidote exists
- Decontamination: Activated charcoal is ineffective at clinical presentation due to the extreme delay in symptom onset
- Renal Management: Initiate aggressive fluid resuscitation to maintain renal perfusion during early oliguria
- Track serum creatinine, BUN, and serum electrolytes (specifically potassium) every 12 to 24 hours
- Initiate immediate hemodialysis upon documentation of AKI, persistent anuria, fluid overload, or refractory hyperkalemia
- Long-Term Prognosis: Over 70% of symptomatic patients sustain permanent, irreversible renal damage. Long-term maintenance hemodialysis is highly probable; transition immediately to a kidney transplant evaluation protocol.
Funeral Bell
iNaturalist
Amatoxin Hepatotoxicity Toxidrome (Galerina marginata)
- Gastrointestinal Phase (6–24 hours): Sudden, severe, cholera-like diarrhea (rice-water style), intractable vomiting, severe abdominal cramping, profound dehydration
- Latent / False Recovery Phase (24–48 hours): GI symptoms subside. Patient appears improved but serum transaminases (AST/ALT) and bilirubin begin to rise exponentially
- Hepatic Phase (48–96 hours): Fulminant hepatic necrosis, profound coagulopathy (prolonged PT/INR), encephalopathy, hepato-renal syndrome, multiorgan failure, coma
- Decontamination: If presentation within 12–24 hours, initiate multi-dose Activated Charcoal at 1g/kg PO or via nasogastric tube every 4 hours to interrupt enterohepatic recirculation
- Aggressive IV crystalloid infusion to maximize renal clearance of circulating amatoxins
- Silibinin (Legalon SIL): Loading dose 5mg/kg IV over 1 hour, followed by continuous infusion 20mg/kg/day for 3 to 4 consecutive days
- N-Acetylcysteine (NAC): 150mg/kg IV over 1 hour loading, followed by 50mg/kg IV over 4 hours, then 100mg/kg IV over the subsequent 16 hours
- Transplant Assessment: Monitor PT, INR, AST, ALT, total bilirubin, creatinine, and arterial pH every 6 hours. Calculate King’s College Criteria continuously. Contact regional liver transplant team immediately upon early encephalopathy or progressive INR >2.5
Section 4: Advanced Diagnostic Assays & Biomarker Detection Windows
Amatoxin Assays (Galerina marginata)
- Urinary ELISA: Primary point-of-care rapid screening method. Qualitative or semi-quantitative results within 90 minutes. Optimal clinical detection window: 6 to 36 hours post-ingestion.
- LC-MS/MS: Gold standard for confirmation. Limit of Detection down to 1ng/mL in urine. Can reliably identify intact α-, β-, and γ-amanitins for up to 72 to 96 hours post-exposure.
- Serum Kinetics: Serum testing highly discouraged. Amatoxins clear rapidly from blood — often completely undetectable in serum 4 to 6 hours post-ingestion, typically before the first GI symptoms present. Use urine.
Orellanine Assays (Cortinarius rubellus / orellanus)
- LC-MS/MS: Orellanine quantified using matrix-matched calibration. LOD for fresh tissue: 20ng/g (0.02 ppm).
- Biopsy Confirmed Persistence: Orellanine rapidly concentrates in renal tissue and can be verified from a standard renal needle biopsy for up to 6 months post-ingestion.
- Serum and Urine Screening: Standard hospital labs lack a rapid assay for orellanine. Serum and urine levels are generally undetectable by the time a patient presents with advanced kidney injury. Diagnosis depends heavily on history, renal biopsy pathology, and LC-MS/MS testing of leftover mushrooms.
Section 5: Expanded Baltic Region Lookalikes Table

Section 6: Precise Fluid Resuscitation Protocols
Pediatric Human Fluid Management
- Indication: Signs of severe volume depletion or hypovolemic shock from early GI purging
- Protocol: IV bolus of Isotonic Crystalloid (0.9% Normal Saline or Balanced Salt Solution) at 20mL/kg over 10–20 minutes. Repeat up to 3 times if necessary to restore perfusion, provided no signs of fluid overload or pulmonary edema.
- ≤10 kg: 4mL/kg/hour
- 11–20 kg: 40mL/hour + 2mL/kg/hour for each kg above 10 kg
- >20 kg: 60mL/hour + 1mL/kg/hour for each kg above 20 kg
- Amatoxin Enhancement: Scale final calculated maintenance rate by 1.5× to 2× baseline, maintaining target urine output >2mL/kg/hour. Track serum electrolytes and glucose continuously.
Pediatric / Small-Breed Veterinary Fluid Management
- Canine (<10 kg): Isotonic crystalloids at 10–15mL/kg over 15 minutes. Re-evaluate perfusion markers.
- Feline: Isotonic crystalloids at 5–10mL/kg slowly over 20 minutes. Avoid aggressive volume loading due to high risk of occult cardiomyopathy and rapid volume overload.
- Canine Maintenance Rate (mL/day) = 132 × (Body Weight in kg)0.75
- Feline Maintenance Rate (mL/day) = 80 × (Body Weight in kg)0.75
- Toxin Diuresis: Scale baseline maintenance rate to 2–3× the calculated volume to force continuous renal clearance
- Monitoring: Strict urinary output — must match or exceed 2–4mL/kg/hour. If urine output drops below 1mL/kg/hour despite fluid loading, immediately decrease to maintenance levels to prevent pulmonary edema or cerebral swelling and check for anuric renal failure.
Regional Admissions & Dispatch Reference
Poison Control Centers (Human)
Involutin-Bearing Species
Paxillus involutus carries involutin, which induces immune-mediated hemolytic anemia on repeat exposure. Single ingestion may be asymptomatic; the danger escalates dramatically with repeated consumption over seasons or years.
Brown Roll-Rim
iNaturalist
- Immediate Stabilization & Decontamination
- Airway: Secure immediately if respiratory distress or altered mental status
- Activated Charcoal: 1 g/kg PO once within first hour if airway protective reflexes intact
- First-Line Immunological Interventions
- High-Dose Corticosteroids — initiate immediately to halt antibody-mediated erythrocyte destruction
- Adult: Methylprednisolone 1–2 mg/kg IV every 6 hours OR Dexamethasone 4–8 mg IV every 6 hours
- Pediatric: Methylprednisolone 1–2 mg/kg IV split into two daily doses
- Therapeutic Plasma Exchange (TPE) — mandatory first-line for progressive hemolysis or rapid hematocrit drop. Directly removes circulating immune complexes and free hemolytic antibodies.
- High-Dose Corticosteroids — initiate immediately to halt antibody-mediated erythrocyte destruction
- Fluid and Renal Management
- Euvolemic fluid management — balanced crystalloids (Plasmalyte or Lactated Ringer’s), target urine output 1–2 mL/kg/hour. Do NOT hyper-hydrate or force diuresis.
- Early CRRT — initiate at first sign of: AKI or rising creatinine, oliguria/anuria refractory to fluid titration, hyperkalemia, or metabolic acidosis. CRRT clears free hemoglobin and inflammatory cytokines without worsening volume overload.
Species: Brown Roll-Rim (Paxillus involutus)
- Induce emesis (Apomorphine in dogs, Dexmedetomidine in cats) if within 1–2 hours and asymptomatic
- Activated Charcoal 1–2g/kg PO with osmotic cathartic if neurologically intact
- Euvolemic IV crystalloid management to maintain normovolemia — do not use forced or alkaline diuresis
- Monitor PCV/TS, CBC, bilirubin, creatinine every 6–12 hours
- Blood transfusion if PCV falls below 20% or clinical signs of circulatory compromise
- Dexamethasone 0.1–0.2mg/kg IV for confirmed immune-mediated component
- Therapeutic plasma exchange (TPE) is available at specialist veterinary centers for severe cases
- Do not allow this animal to consume Paxillus again — sensitization is permanent
Ibotenic Acid / Muscimol-Bearing Species
Amanita muscaria and Amanita pantherina carry ibotenic acid and muscimol. These are CNS-active compounds, not muscarine. Supportive care is the primary treatment. Do NOT administer Atropine.
Fly Agaric / Panthercap
iNaturalist
- Supportive care is the mainstay — no specific antidote
- Activated Charcoal 1g/kg PO if presentation within 1–2 hours and airway protected
- Benzodiazepines (Diazepam 5–10mg IV, titrate to effect) for seizure control and agitation
- IV fluids for hydration maintenance
- Monitor airway — respiratory depression possible in severe A. pantherina ingestion
- ⚠️ CRITICAL WARNING: DO NOT administer Atropine — these species do NOT cause muscarine toxidrome. Atropine will worsen the anticholinergic CNS syndrome and can be fatal.
- Physostigmine 0.5–2mg IV slowly may be considered for severe anticholinergic delirium — only under specialist guidance
- Most cases resolve in 6–12 hours with supportive care
Species: Fly Agaric / Panthercap (Amanita muscaria / Amanita pantherina)
- Induce emesis immediately if within 30–60 minutes and animal is alert — use Apomorphine (dogs) or Dexmedetomidine (cats)
- Activated Charcoal 1–2g/kg PO after emesis if neurologically intact
- Diazepam 0.5mg/kg IV to effect for tremors or seizures
- IV crystalloid fluids at maintenance rate — do not over-fluid
- Monitor respiratory rate — intubate if respiratory depression develops
- ⚠️ CRITICAL WARNING: DO NOT administer Atropine — it will severely exacerbate the CNS delirium. This is the opposite of muscarine toxidrome.
- Most mild cases resolve in 6–12 hours. A. pantherina ingestion — monitor minimum 24 hours.
Field Survival & Decontamination Protocols
Standardized Spore Print Protocol
- Sever the fungal pileus (cap) cleanly from the stipe (stem) at the apex
- Place the pileus with the hymenium (gills) facing downward onto a split media substrate — half white, half black non-absorbent cardstock or a clean glass microscope slide
- Invert a clean glass beaker or bowl over the specimen to isolate from ambient airflow and trap natural humidity
- Allow to stand undisturbed for 2–6 hours
- Analyze resulting spore deposition:
- Rusty-Brown to Cinnamon-Brown: Confirms Cortinarius species matrix
- Ochre-Brown to Rusty-Brown: Confirms Galerina species matrix
- White to Pale Cream: Characteristic of Amanita complex species
Cross-Contamination & Handling Rules
- Toxin Transfer Dynamics: Orellanine and α-amanitin are large complex molecules that cannot pass through intact human dermal barriers. Physical touch does not cause systemic toxicity.
- Separation Integrity: If a collection basket contains a single confirmed Tier 1 lethal mushroom (Cortinarius spp. or Galerina marginata), the entire harvest must be destroyed. Washing or cooking will NOT degrade these heat-stable compounds.
- Hygiene Measures: Thoroughly wash hands with soap and water after handling toxic specimens. Mechanically clean all collection tools, knives, and scales.
Species 1 & 2: Deadly Webcap / Fool’s Webcap (Cortinarius rubellus / orellanus)
- If ingestion confirmed within 2–4 hours: gastric lavage and Activated Charcoal 1–2g/kg PO with osmotic cathartic (e.g. sorbitol), provided patient is neurologically intact
- Immediate, continuous IV fluid therapy with isotonic crystalloids at 2–3× maintenance rates to maintain urine output >2mL/kg/hour
- Insert indwelling urinary catheter to quantify output. Measure baseline creatinine, BUN, phosphorus, and potassium daily
- If oliguria progresses to anuria despite fluid loading, discontinue aggressive fluid volumes to prevent fatal pulmonary edema. Transfer immediately to facility capable of veterinary CRRT or hemodialysis.
Species 3: Funeral Bell (Galerina marginata)
- Multi-dose Activated Charcoal (1–2g/kg PO) every 4–6 hours for first 24 hours to trap toxins undergoing biliary recycling
- N-Acetylcysteine (NAC): Loading dose 140mg/kg IV slowly over 20 minutes, then maintenance 70mg/kg IV every 6 hours for minimum 48–72 hours
- Silybin/Silymarin: If injectable silibinin unavailable, administer high-dose standardized oral Silymarin 20–50mg/kg/day split into multiple doses
- Injectable Vitamin K1: 2.5–5mg/kg SQ or PO daily if PT/INR or activated clotting times extend
- Constant IV fluid support supplemented with 2.5–5% Dextrose if hepatic glycogen stores fail and hypoglycemia develops
- Monitor baseline liver panels every 12–24 hours
- Complete Blood Count (CBC)
- Liver Function Tests (ALT/AST, Bilirubin)
- Kidney Panels (Creatinine, BUN)
- Coagulation Panels (PT/APTT)
