Amanita franchetii, also known as Franchet's amanita,[1] is a species of fungus in the family Amanitaceae.

Taxonomy

It was given its current name by Swiss mycologist Victor Fayod in 1889 in honor of French botanist Adrien René Franchet.[2]

As A. aspera var. franchetii, it had the name yellow-veiled amanita.[3]

There exists a variety known as A. franchetii var. lactella that is entirely white except for the bright yellow universal veil remnants.[4]

Description

The cap is 5–12 centimetres (2–4+12 inches) wide, and is yellow-brown to brown in color. The flesh is white or pale yellow and has a mild odor.[5] The closely spaced gills are the same color as the flesh. The stipe is thick and larger at the base, also white to yellowish; loose areas of yellow veil form on the base. A thick ring is left by the partial veil.[6]

Similar species

A similar fungus in western North America was also referred to as A. franchetii, but was long suspected of being a separate, undescribed species,[7] and in 2013 was formally described under the name A. augusta.[8]

Distribution and habitat

A. franchetii occurs in Europe and North Africa with oaks (Quercus ssp.), chestnuts (Castanea ssp.), and pines (Pinus ssp.).[7]

A. franchetii var. lactella is found in the western Mediterranean region, associated with several species of oak (Quercus suber and Q. robur) and hornbeam (Carpinus betulus),[4] and is also reported from Serbia.[9]

Edibility

A. franchetii is considered inedible,[10][3] and is reported as being toxic when raw or undercooked.[6] Although the species was implicated in the 2005 deaths of ten people in China who displayed symptoms similar to those caused by alpha-Amanitin poisoning,[11] this case report has been called into question for possible misidentification of the mushrooms involved.[12]
