The popular white ones with peanut and coconut filling are usually sold out first, they are similar to mochi but not dusted with flour.
After reading the reviews on OpenRice, I found out they were called 雞屎籐 teacakes, made from a herb called 雞屎籐 (Paederia scandens).
For me, they tasted Ok, slightly chewy, and sweet, the size was bite-sized.
It costs $4 for 4.
Apart from looking like Chinese mushrooms, they reminded me of Beadlet Anemones found in rocky shores around all coasts of the UK
