Mycopteris

Mycopteris is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] It is known from the American tropics.

Description

Most members of the genus are epiphytes, although some grow on soil or on rocks.[2]

Taxonomy

The genus was first described by Michael Sundue in 2014 to receive some of the species of the genus Terpsichore. When that genus was described by Alan R. Smith in 1993, he divided it into five informal groups. Subsequent morphological and molecular studies showed that Terpsichore was polyphyletic, but its groups were largely monophyletic and could furnish the basis of new genera. These genera were described over the next several years; Sundue's new genus Mycopteris, encompassing the T. taxifolia group, was the last group to be removed from Terpsichore sensu lato.[2]

The name "Mycopteris" is derived from the Greek roots myco-, "fungus", and -pteris, "fern", referring to the near-universal association of these ferns with the ascomycete fungus Acrospermum. Sundue initially placed seventeen species in the genus, one of which was newly described and another elevated from a variety.[2] He suggested that another five to ten species might be described after the completion of a monograph on the genus.[2] In 2017, he described a new species, Mycopteris martiniana, from Mexico.

Distribution

gollark: I disagree with that, actually.
gollark: It also took something like 10% of the time to write, which is good.
gollark: - unbee python- the osmarkspythonbuildsystem™ functions/variables, to the extent that they exist, constitute an "embedded domain specific language"- Python is more featureful than Dale syntax, however- well, mine does it seminonawfully, if you don't mind its complete lack of job throttling
gollark: Via parser combinators, I can define *exactly* what I want and easily parse it, unless it involves left recursion in which case aææææßæææaæææaaaaæææææææ.
gollark: This is why I combinate all my parsers.
