Chrysotrichaceae

Chrysotrichaceae is a family of lichenized fungi in the order Arthoniales. Member of this family have a widespread distribution, but are especially prevalent in tropical areas. "Chrysothrichaceae" and "Chrysothricaceae" are alternative spellings that have been used in some older publications; the latter was used by Alexander Zahlbruckner in the protologue publication. Both of these spellings are considered incorrect, and the current spelling has been formalised following a proposal for conservation of Chrysotrichaceae against Pulverariaceae (an earlier synonym).
