2. Neither paper samples the Western US or Mexico. Species assertions for observations in those regions are suspect for the same reasons as those mentioned in the last comment.
Alan, in your dozens of C. chrysopepla proposals does not support the notion that all western hemispheric C. asprata complex members are C. chrysopepla. On the contrary, both Qin and Yang and Moreau et al, 2015 refer to a (sequenced) collection of C. asprata s.s. from the Caribbean (Martinique). If it exists there, it could exist elsewhere in the Neotropics.
Surely, present-day concepts on not just this species complex but the genus at large are handicapped by sampling biases which hardly take Neotropics into account at all, despite the group’s widespread distribution in this region. This is a kingdom-wide trend. Asserting species-level IDs for Neotropical fungi on the basis of papers whose analyses don’t include Neotropical matierial is problematic, to say the least.
