An updated checklist of the lichens of St. Eustatius, Netherlands Antilles

Abstract

In the course of a multi-taxon biodiversity inventory for the island of St. Eustatius, lichens were collected from 11 plots representing different vegetation types. From these collections, 126 lichen species are reported, 54 of which are new reports for St. Eustatius. Most species could be identified to species level based on morphological and chemical characters. In a few cases, mtSSU DNA sequences were generated for a preliminary molecular identification and future phylogenetic studies. In total, 263 identified lichen species are currently known from St. Eustatius, as well as some additional genera with yet unidentified species and lichenicolous fungi.

Hongos asociados al mangle rojo Rhizophora mangle (Rhizophoraceae) en la Reserva de la Biosfera Isla Cozumel, Quintana Roo, México

“…(Lythraceae) en Sri Lanka (Maduranga et al, 2018). Los últimos registros a nivel mundial se encuentran en Puerto Rico (Mercado-Díaz y Sur, 2009), Florida (Lucking et al, 2011), noroeste de la India (Das et al, 2013), Bermuda (Berger y LaGreca, 2014), noroeste de Brasil (Leite et al, 2015), norte de Estados Unidos de América (Esslinger, 2016) y Antillas Holandesas (Aptroot y Stech, 2018). En México se ha registrado en Jalisco (Herrera-Campos et al, 2017).…”

“…El registro presentado en este estudio constituye el primero para el estado de Quintana Roo. (Minter et al, 2001), Venezuela (Neuwirth, 2008), Puerto Rico (Mercado-Díaz y Sur, 2009), norte de Estados Unidos de América (Esslinger, 2016), el archipiélago Seychelles (Neuwirth y Stocker-Wörgötter, 2017) y las Antillas Holandesas (Aptroot y Stech, 2018). Se cita por primera vez para México.…”

The Lichen Genus Sticta (Lobariaceae, Peltigerales) in East African Montane Ecosystems

“…However, our results indicate that none of the East African species with flattened isidia actually represent S. xanthotropa : Sticta andina has a strong K+ yellow color reaction, while S. xanthotropa is K− [ 32 ]; Sticta afromontana has a robust thallus, while S. xanthotropa is described as “papery thin”, and the spores of S. afromontana are larger than those of S. xanthotropa [ 32 ]; Sticta cyanocaperata has a very dark lower surface, while it is pale in S. xanthotropa [ 32 ]. Furthermore, all the aforementioned species are mainly epiphytic, while S. xanthotropa has been reported to mainly grow on rocks and soil [ 32 , 70 ].…”

Gone with the wind: sequencing its type species supports inclusion of Cryptolechia in Gyalecta (Ostropales: Gyalectaceae)

“…2009; Seaward 2010; Roux 2012; Balaji & Hariharan 2013; Ait Hammou et al . 2014; Aptroot & Stech 2018). Gyalecta canariensis from the Canary Islands (see above) has been considered to be another synonym (van den Boom 2010), but the orange-brown apothecial disc of the type material suggests it could represent a different taxon.…”

“…Cryptolechia carneolutea is a rare but possibly widespread species, occurring in Ireland, England, France, Portugal (including the original material of its synonym, Pachyphiale lecanorina J. Steiner 1918), Italy, Macaronesia and Algeria, with scattered and perhaps doubtful records from Canada, the Caribbean, India and New Zealand (Watson et al 1988;Wong & Brodo 1990;Purvis et al 1992;Hafellner 1995;Coppins & Coppins 2002;Sparrius et al 2002;Boom et al 2009;Seaward 2010;Roux 2012;Balaji & Hariharan 2013;Ait Hammou et al 2014;Aptroot & Stech 2018).
