Tropical and Subtropical Lichens: Diversity and Floristics Sipman, H.J.M. [1], Elix, J.A. [2], Nash III, Thomas H. [3]. Hypotrachyna in the neotropics. A total of 140 species of Hypotrachyna (Parmeliaceae, lichenized fungi) are recognized from the neotropics. This is well over 50% of the Hypotrachyna species known world-wide in this primarily tropical genus and includes 85 species thus far only known from the neotropics. Compared to the neotropical species treated by Hale in 1976, we have more than doubled the number of recognized species. Keys are provided; synonymy, descriptions, secondary chemistry, distribution maps, habitats, and a selection of herbarium voucher specimens are given for each species.. Many previously described taxa are reduced to synonymy. Although recent molecular work is consistent with an interpretation that Hypotrachyna in Hale’s sense in polyphyletic, no alternative classification is currently well supported. Thus, for the time being we have followed Hale’s circumscription of the genus.
