These are pictures of Lentinus sajor-caju. Let's look first at "sajor-caju". This scientific name certainly comes from the Malay language. "Sajor" means vegetables and "caju" is wood; meaning: vegetables on wood. Then, Lentinus is a genus name of fungi in the family Polyporaceae. Lentinus is derived from the Latin lent, meaning "pliable", and inus, meaning "resembling". (source).
I think, about its pliability and beauty, it has been witnessed. While about edible, and some other information, these are some that I quoted from Peter E Mortimer et al.,Mushrooms for Trees and People: A field guide to useful mushrooms of the Mekong region, World Agroforestry Centre, 2014, p. 65.
Use: An excellent edible mushroom because of its high protein content and excellent taste.
Time of fruiting: This species normally appears in the middle of the rainy season. In Thailand, Laos, Sri Lanka and China, June and July are the best time for this species.
(That was when I found it in Aceh, Sumatra)
Habitat: Found in clusters on old stumps and fallen trunks in the forests of south east Asia, but not extending to Australasia. The caespitose habitat (caespitose: growing in clusters or tufts) often results in distorted basidiomes (see: Basidiomycota) with excentric or lateral stipes. It is normally a saprobe but according to Bagchree (1960), causes a white rot of both the sap wood and heart wood of many trees, including the economically important crops Hevea sp. and Shorea sp.
