Phylacteria vialis (Schwein.) Pat.
Thelephora tephroleuca Berk. & M.A. Curtis
Common names: Groundwart, ganba-jun or dried beef mushroom
In 2017, it was considered as a new record for Malaysia (Lee, 2017) and commonly growing on the ground under Pterocarpus indicus. Recently, the Pterocarpus indicus is listed in the IUCN red list as endangered species (Barstow, 2018).
Found in North America (McKnight and McKnight, 1987), New Zealand, Australia, and Japan (Corner, 1968). In Malaysia, it was found on the ground near at Forest Research Institute of Malaysia (FRIM) (Lee, 2017) and at Sungai Yu, Forest Reserve, Pahang (photo as attached). There is Pterocarpus indicus but no information from Indonesia, Phillipines, Myanmar, Thailand and Vietnam.
There is a high rate of deforestation and on average for the Southeast Asia region as a whole, forest loss is 1.2% a year and in 2018, Pterocarpus indicus had been listed as endangered (Barstow, 2018) consequently, effecting the Thelephora vialis Schwein growth.
Population Trend: Decreasing
Well known as medicinal mushroom especially in China and also considered as one of the most favored edible mushrooms (Dai et al., 2004; Onose et al., 2008).
