Butyriboletus roseoflavus

Butyriboletus roseoflavus is a pored mushroom in the genus Butyriboletus found in Asia. It was originally described in 2013 as a species of Boletus, but was transferred the following year to the newly created genus Butyriboletus. It is known as xiaomei niuganjun (Chinese: 小美牛肝菌; lit. 'little pretty bolete') or huamei niuganjun (Chinese: 华美牛肝菌; lit. 'fancy pretty bolete') in Yunnan and huandian niuganjun (Chinese: 黄靛牛肝菌; lit. 'yellow-cyan bolete') in Zhejiang. It was formerly misidentified as Boletus speciosus and Boletus appendiculatus. A mushroom identified as xiaomei niuganjun is implicated in a 2014 poisoning leading to lilliputian hallucinations....read more on Wikipedia.
