茶 (chá) is the Chinese character for tea. As well as being used for tea itself, it also appears on menus as 茶樹菇 (chá shà gū) [...].

The English name for 茶沙菇 is a direct translation of the Chinese — "tea tree mushrooms".

In the first paragraph, you have 樹 (tree) but read it "shà" instead of "shù"... and in the second paragraph, you have 沙 (shā/shà) but call it "tree" instead of "sand".

Now I'm confused whether both characters are possible, or one of the two (which one?) is wrong, or what happened.
