Lanna Mushrooms: Het Thop, Het Lom and Kham Mueang Names
Het (เหัดฯ, Kham Mueang reading het) means mushroom. The dictionary describes it as a large fungus whose threads gather into a fruiting body, and says that some kinds are edible while others are poisonous, and some can kill. The rainy season is mushroom season for the people of Lanna, and the Moradok Lanna dictionary records more than twenty Kham Mueang names for Lanna mushrooms.
This article continues the series on Kham Mueang names for fruit and vegetables. It gathers every mushroom name in the dictionary, sorts them into groups with their Lanna script and real photos, and ends with the names the Khon Mueang gave to poisonous mushrooms so that no one would forget them.
Het thop: the mushroom of the first rains
The mushroom the Khon Mueang wait for most is het thop (เหัดฯถอฯบ, Kham Mueang reading het thop), called het phao in central Thai. The dictionary describes a flattened round ball 1–3 cm across, with no stem and no roots, that likes open woodland with loose soil that has been burnt, and that comes up at the start of the rainy season, in May and June.
When young it is soft and white inside; when old the skin turns dark brown, the inside black, and it splits open into a star. The Khon Mueang boil, stir-fry, curry or dry-fry young het thop, or eat it raw dipped in chilli paste.

Poisonous mushrooms: names meant as warnings
Kham Mueang has a general name for poisonous mushrooms, het buea (เหัดฯเบิอฯอ, Kham Mueang reading het buea). The dictionary describes them as poisonous, some deadly to eat; most have a white net-like veil, and some are brightly and beautifully coloured.
The most memorable name is het pi nong lai (เหัดฯพี่น้อฯงหลฯายฯ, Kham Mueang reading het pi nong lai), literally "many-relatives mushroom". The dictionary explains that it covers several poisonous mushrooms; whoever eats them may die, which brings crowds of relatives to visit, or to the funeral. The name is a dark joke and a warning in one word.
Besides poisonous mushrooms there are mushrooms that simply cannot be eaten, such as het kadang (เหัดฯระฯกด้างฯ, Kham Mueang reading het kadang): a hard, brown, fan-shaped bracket growing on rotten stumps, which the dictionary says is not edible.
