Rename values in a list based on a dataframe

I am using the function "ps_venn" to compare taxa present in different samples with a phyloseq object. This function outputs a nested list of each sample(s) and the intersecting taxa:

Because this is metabarcoding data, the taxa have these long complicated names. I have a dataframe of the taxa lineages formatted like this:

I would like to rename the taxa in the list based on the name in the "class" column.

I have no experience with lists in R, so I'd appreciate any guidance. Thanks!

Edit:
Here is the function I used on my phyloseq object:

cvenn.met <- ps_venn(combined_c, group = "method", weight = FALSE, plot = FALSE)

Here is the beginning of the output list:

list(OBB = c("329966c334544d14f9985b98b813f40f",

Here is the beginning of my taxonomy dataframe:

    species = c(NA_character_, NA_character_, NA_character_, 
    NA_character_, NA_character_, NA_character_), Consensus = c(0.625, 
    0.75, 0.714, 0.714, 1, 0.6)), row.names = c(NA, 6L), class = "data.frame")

I would like to rename the strings of text in my list with their corresponding taxonomy in the "class" column.

If your output is called out and the taxonomy data frame tax, using lapply (on a modified dataset for demonstration purposes), with setdiff for the non-matching strings.

out[[3]][2] <- "003ba56d29607b45d8599085b8b69afa"

lapply(out, \(x) c(tax$class[tax$X %in% x], setdiff(x, tax$X)))
