Gomphillus Morchelloides (Ostropales: Gomphillaceae), A New Lichen Species from Chile and Papua New Guinea

Revision of two collections of Gomphillus from Papua New Guinea and Chile, previously identified as Gomphillus ophiosporus and G. calycioides, respectively, revealed that these represent an undescribed species, G. morchelloides Luecking & Serus. The new species is characterized by short-stipitate, apically much broadened, cerebriform to morchelloid apothecia and ascospores intermediate between those of G. ophiosporus and G. calycioides.
