To the Editor.—  The recently reported unfortunate experience of two physicians with a species of mushroom frequently identified as nonpoisonous, Tricholomopsis platyphylla, sometimes known as the "Platterful Mushroom," emphasizes the unknown toxicity of many species of mushrooms.1 This was also noted earlier in The Journal in a review of mushroom poisoning.2 Since many cases of mushroom poisoning may be handled on the telephone, in the physician's office, or even informally in consultation along the trail, they remain unreported, and potentially useful information is lost. The North American Mycological Association has established a Mushroom Poisoning Case Registry, and we invite reports of all instances of mushroom poisoning of any degree.
