Polymorphism of vegetative propagules in Punctelia punctilla (Parmeliaceae, Lecanorales) and the delimitation of the species

The ontogeny and polymorphism of the vegetative propagules of Punctelia punctilla (Hale) Krog, which have previously been misinterpreted, are described with detail. A similar propagule polymorphism was observed in specimens which fit in the diagnosis of P. missouriensis G. Wilh. & Ladd. Conseque...

Sumario:The ontogeny and polymorphism of the vegetative propagules of Punctelia punctilla (Hale) Krog, which have previously been misinterpreted, are described with detail. A similar propagule polymorphism was observed in specimens which fit in the diagnosis of P. missouriensis G. Wilh. & Ladd. Consequently, a wide concept of P. punctilla is proposed, considering the name P. missouriensis as a synonym, and its distribution is extended.
