Three New Species in the Biatoropsis usnearum Complex

Abstract

Three new species of Biatoropsis are formally described based on our previous molecular studies, and on additional molecular, morphological, and ecological data. Biatoropsis protousneae sp. nov. is confined to Protousnea dusenii. Biatoropsis minuta sp. nov. is characterized by the small and brown to black basidiomatal galls, and by growing on Usnea barbata and U. lapponica. Biatoropsis hafellneri sp. nov. is distinguished by 2-celled basidia with cells that elongate laterally at maturity, and by growing on species of the Usnea fragilescens aggregate. A fourth Biatoropsis species is left unnamed, and two other lineages are not described, all waiting for the study of additional material.

First checklist of lichens and lichenicolous fungi from Mauritius, with phylogenetic analyses and description of new taxa

“…PCR amplifications were performed using Illustra™ Hot Start PCR beads according to the manufacturer's instructions, with the primer combinations and settings described in Millanes et al (2011). Sequencing followed Millanes et al (2016).…”

“…squamosa, mainly from Arup et al (2013). In addition to 24 Biatoropsis specimens representing all known species in the genus and the seven clades studied in Millanes et al (2014Millanes et al ( , 2016, seven additional specimens from the Indian Ocean were included in the molecular study (Table 1).…”

“…Notes. Millanes et al (2014; Millanes et al (2016) are not considered here, owing to the deviating morphology of basidiomatal galls (broad, almost disk-like, concolorous to the host thallus), and will be treated elsewhere. The available nice and richly fertile material from Mauritius and Rodrigues pemits us to describe the species formally here.…”

New records of lichens and lichenicolous fungi from Latvia, with a list of lichenicolous fungi reported from Latvia

“…str.) given by Millanes et al (2016), so it is assumed that only one species of Biatoropsis is known from Latvia.…”

Four new species of Tremella (Tremellales, Basidiomycota) based on morphology and DNA sequence data

“…Tremella sensu lato includes approximately 90 species, more than half of which are known to exclusively parasitize specific lichenized fungal hosts (Diederich and Marson 1988; Diederich and Christiansen 1994; Diederich 1996, 2003, 2007, Sérusiaux et al 2003; Kirk et al 2008; Zamora 2009, Zamora et al 2011, 2016; Millanes et al 2012, 2014, 2015, 2016; Diederich et al 2014; Kout et al 2015; Lindgren et al 2015; Westberg et al 2015; Spirin et al 2017). This genus splits into eight monophyletic groups in combination with several isolated species in Tremellales.…”
