An expert has warned against eating poisonous fungi after a hiker spotted what he thought was the world’s deadliest fungi, called poison fire coral, but which turned out to be a less harmful species, Clavulinopsis miyabeana.
A hiker surnamed Lee (李) on Saturday said that he took a photograph of a cluster of red fungi he saw on his way to Gaoyaoshan (高腰山) in New Taipei City’s Wulai District (烏來) last month.
After discussing the picture with a retired science teacher, they concluded that it looked like poison fire coral, also known as Podostroma cornu-damae, which is native to Japan, but has been found as far away as Australia.

Lee became concerned that people might pick the bright red fungus for consumption.
Fungus expert Lin Tzu-chao (林子超), who published a paper on poison fire coral as a new species in Taiwan, said that the fungus in the picture Lee took is likely Clavulinopsis miyabeana, based on its appearance.
Poison fire coral has rodlike, solid, fleshy and reddish orange stromata that point upward and are white inside, Lin said, adding that they are 6cm to 10cm in height and 0.7cm to 1cm in diameter.
Clavulinopsis miyabeana is different in that it is hollow and rodlike, and 3cm to 4cm tall, he said.
Poison fire coral, a type of saprophytic fungus, grows in scattered patterns on the ground beneath broad-leaved trees, and its spores are dispersed by wind, Lin said.
It has been found in China, South Korea, and on Orchid Island (Lanyu, 蘭嶼), but not on Taiwan proper, he said.
While touching poison fire coral is not harmful, it must not be eaten, he said.
There was a case in South Korea of two people drinking water cooked with wild lingzhi mushroom they gathered without knowing that it contained a piece of poison fire coral, Lin said.
One died and the other suffered from desquamation of skin on the palms and soles, severe septicemia and organ failure, he said.
Consuming any type of poisonous fungus can cause vomiting, diarrhea and hallucinations, while poison fire coral additionally causes severe liver damage, he said.
There is no antidote for the poison, so those who have consumed it can only be treated with supportive therapy, he added.
A tropical depression east of the Philippines became a tropical storm early yesterday, the Central Weather Administration (CWA) said, less than a week after a typhoon barreled across the nation. The agency issued an advisory at 3:30am stating that the 22nd tropical storm, named Yinxing, of the Pacific typhoon season formed at 2am. As of 8am, the storm was 1,730km southeast of Oluanpi (鵝鑾鼻), Taiwan’s southernmost point, with a 100km radius. It was moving west-northwest at 32kph, with maximum sustained winds of 83kph and gusts of up to 108kph. Based on its current path, the storm is not expected to hit Taiwan, CWA
Residents have called on the Taipei City Government to reconsider its plan to demolish a four-decades-old pedestrian overpass near Daan Forest Park. The 42-year-old concrete and steel structure that serves as an elevated walkway over the intersection of Heping and Xinsheng roads is to be closed on Tuesday in preparation for demolition slated for completion by the end of the month. However, in recent days some local residents have been protesting the planned destruction of the intersection overpass that is rendered more poetically as “sky bridge” in Chinese. “This bridge carries the community’s collective memory,” said a man surnamed Chuang
FATALITIES: The storm claimed at least two lives — a female passenger in a truck that was struck by a falling tree and a man who was hit by a utility pole Workers cleared fallen trees and shop owners swept up debris yesterday after one of the biggest typhoons to hit the nation in decades claimed at least two lives. Typhoon Kong-rey was packing winds of 184kph when it slammed into eastern Taiwan on Thursday, uprooting trees, triggering floods and landslides, and knocking out power as it swept across the nation. A 56-year-old female foreign national died from her injuries after the small truck she was in was struck by a falling tree on Provincial Highway 14A early on Thursday. The second death was reported at 8pm in Taipei on Thursday after a 48-year-old man
