Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.[2]
Taxonomy
The fungus was first formally described by Carlo Luigi Spegazzini in 1898 as a member of genus Nectria. Spegazzini collected the type specimen from South America, where it was growing on Punctelia constantimontium.[3] In 1984, Rolf Santesson proposed to transfer the taxon to genus Nectriella.[4] Rosalind Lowen transferred it and several other lichenicolous species to Pronectria in 1990.[5] Finally, Javier Etayo transferred the species to the genus Xenonectriella in 2017, giving it the binomial name by which it is currently known.[6]
Hosts
One of its hosts is the common foliose lichen species Punctelia borreri. Infection by X. subimperspicua creates discoloured or bleached areas on the thallus of the host;[7] the perithecia of the fungus then become more readily visible.[2] Two varieties of Xenonectriella subimperspicua have been defined: var. subimperspicua mostly parasitizes Parmelia and Punctelia but has also been recorded on Physcia, while var. degenerans parasitizes Parmotrema.[8]
