In 2013, Damien Ertz and colleagues showed through molecular analysis that the genus Sporodochiolichen, proposed by André Aptroot and Harrie Sipman in 2011,[5] should be reduced to synonymy with Tylophoron. The type species of Sporodochiolichen (S. lecanoricus) was demonstrated to be conspecific with Tylophoron hibernicum, despite initial descriptions suggesting different photobiont partners. This taxonomic change left three additional species originally described in Sporodochiolichen (S. flavus, S. papillatus, and S. pigmentatus) requiring transfer to other genera, though their precise taxonomic placement remains uncertain. The remaining Sporodochiolichen species differ from Tylophoron in having golden yellow or pink sporodochia that produce simple or distoseptate conidia, compared to Tylophoron's typically pale or brown sporodochia with zero or one septate (non-distoseptate) conidia.[2]
