“…is a subcosmopolitan species ( McDonald et al 2003 ; Hodkinson et al 2014 ; Magain and Sérusiaux 2015 ; Di Meglio and Goward 2023 ; Kaasalainen et al 2023 ) and, in South America, is known only from Brazil ( Magain and Sérusiaux 2015 ; Widhelm et al 2018 ). However, numerous morphodemes of S. fuliginosa are known from the Neotropics ( Moncada et al 2015 ); therefore, it is likely that Bolivian material may have represented one or several of these. It is the same with S. laciniata.…”

“…The presence of propagules in the form of isidia and lobules is also characteristic of S. macrofuliginosa B. Moncada & Lücking from Colombia ( Moncada et al 2015 ) and S. parvilobata Merc.-Díaz from Puerto Rico ( Mercado-Díaz et al 2020 ). However, in S. macrofuliginosa , isidia are cylindrical, whereas in S. parvilobata , they are granular to globular.…”

“…These taxa also differ from S. isidiolobulata in the upper surface of the thallus, which is scrobiculate to foveolate with sparse laminal apothecia in the Colombian species and smooth to scrobiculate without apothecia in the Puerto Rican species. In addition, the primary tomentum is dense to the lobe margins and spongy in S. macrofuliginosa and sparse, but sometimes dense and hirsute to fasciculate in S. parvilobata ( Moncada 2012 ; Moncada et al 2015 ; Mercado-Díaz et al 2020 ).…”

Four species of the genus Sticta are described as new from Bolivia, based on morphological examination and phylogenetic analysis of the fungal ITS barcoding marker. Additionally, two species are reported as new to Bolivia (their identification confirmed by molecular data) and one previously reported species is confirmed by molecular data for the first time. Detailed morphological and anatomical descriptions are provided for all new species. Two of the new species, S. isidiolobulata Ossowska, B. Moncada, Lücking & Kukwa and S. madidiensis Ossowska, B. Moncada, Lücking & Kukwa belong to clade I, as defined in previous studies. In contrast, S. montepunkuensis Ossowska, B. Moncada, Lücking & Kukwa and S. macrolobata Ossowska, B. Moncada, Lücking & Kukwa, also described here as new to science, belong to clade III. Sticta isidiolobulata has an irregular to suborbicular thallus of medium size, with isidia developing into spathulate lobules, cyanobacterial photobiont and apothecia with entire to weakly-crenate margins. The large irregular thallus of the cyanobacteria-associated S. macrolobata has broad lobes, apothecia with verrucous to tomentose margins and cyphellae with raised margins, whereas S. madidiensis has a medium-sized, palmate to irregular thallus with a stipe, but without vegetative propagules and apothecia. Sticta montepunkuensis has large and irregular thalli with green algae as photobiont, apothecia with crenate to verrucous margins and urceolate cyphellae with a wide pore and a scabrid basal membrane. Two species, S. beauvoisii Delise and S. riparia Merc.-Díaz are reported as new to Bolivia (the latter also as new to South America) and belong to clade III. Sticta tomentosa (Sw.) Ach., species confirmed from Bolivia by molecular data, belongs to clade II. Sticta beauvoisii is characterised by a smooth yellowish-brown upper surface with darker apices and abundant, marginal isidia and a brown lower surface with golden-chocolate brown primary tomentum and sparse, golden-brown rhizines. Sticta riparia has a strongly branched thallus, with undulate lobes and abundant, marginal, palmate, grey to dark brown phyllidia and greyish-brown lower surface with the primary tomentum absent towards the margins. Sticta tomentosa has palmate, bluish thalli with white cilia and abundant, submarginal apothecia and creamy-white lower surface with a sparse, white primary tomentum.

“…The name Sticta fuliginosa has traditionally been applied to all forms with more or less broad, rounded lobes with laminal isidia (Joshi & Awasthi 1982; Swinscow & Krog 1988; Galloway 1994 a , 2001, 2007; Galloway et al 1995; Büdel et al 2000; Brodo et al 2001; Farkas 2003; Galloway & Thomas 2004; Jørgensen & Tønsberg 2007; Makryi 2008; Smith et al 2009). Molecular phylogenetic data, however, have demonstrated that this morphodeme corresponds to more than a dozen, mostly unrelated species (Moncada et al 2014 a , 2015, 2020; Magain & Sérusiaux 2015). Surprisingly, even in a narrow sense supported by molecular data, S. fuliginosa s. str.…”

A taxonomic reassessment of the genusSticta(lichenized Ascomycota:Peltigeraceae) in the Hawaiian archipelago

The taxonomy of the genus Sticta in Hawaii is reassessed, based on a separately published molecular phylogeny using the fungal barcoding marker ITS. Based on Magnusson and Zahlbruckner's treatment from 1943 and Magnusson's catalogue from 1955, seven species of Sticta and three infraspecific taxa had been reported from the archipelago, all widespread except the putative endemic S. plumbicolor. Here we provide a taxonomic treatment of 13 taxa, 12 species and one subspecies, distinguished in a previous phylogenetic analysis: S. acyphellata, S. andina, S. antoniana, S. emmanueliana, S. flynnii, S. fuliginosa, S. hawaiiensis, S. limbata, S. plumbicolor, S. scabrosa subsp. hawaiiensis, S. smithii, S. tomentosa and S. waikamoi. All taxa are described, discussed and illustrated and a dichotomous key is presented. The implications of revised species taxonomies for studies in other fields such as ecology, ecophysiology, biogeography, biochemistry, and applications such as environmental monitoring are discussed. We also propose a protocol to use Sticta lichens to monitor the environmental health of Hawaiian ecosystems.

“…Los líquenes son una asociación simbiótica entre un hongo (denominado micobionte, el cual puede ser un ascomiceto o un basidiomiceto) y un organismo fotosintético (fotobionte, el cual frecuentemente es un alga verde o una cianobacteria) (Nash, 2008). También pueden formar simbiosis tripartitas o simbiodemas (hongo, alga verde y cianobacteria), que amplían el espectro de distribución y de crecimiento de los hongos liquenizados (Green & Lange, 1991;Dahlman & Palmqvist, 2003;Henskens, et al, 2012), como sucede en los géneros Lobaria, Pseudocyphellaria y Sticta de la familia Lobariaceae (Moncada, et al, 2013(Moncada, et al, , 2014(Moncada, et al, , 2015. La relación directa entre los líquenes y el ambiente mantiene un flujo constante de agua, carbono, nitrógeno y otros elementos esenciales que permite categorizarlos como bioindicadores, los cuales reaccionan ante los distintos niveles de fragmentación o alteración del medio (Lücking, et al, 2008(Lücking, et al, , 2017, la contaminación y los cambios climáticos (Estrabou, 2007;Lijteroff, et al, 2009;Ardila, et al, 2014), y aportan información sobre los principales factores ambientales como el pH, la disponibilidad de nutrientes, la humedad, la temperatura y la iluminación en sistemas maduros (Hernández et al, 1998;Lücking, 1999;Rosabal, et al, 2012bRosabal, et al, , 2013.…”

El objetivo del estudio fue contribuir al conocimiento de la composición y la diversidad, la especificidad de forófito y las preferencias microambientales de líquenes cortícolas de un bosque subandino en la región Centro de Colombia (Ibagué, Tolima). Se seleccionaron 25 individuos de cinco especies arbóreas; se estimó el porcentaje de cobertura de cada especie de liquen; se determinaron los parámetros del micrositio (pH de la corteza y diámetro a la altura del pecho, DAP) y del microclima (temperatura, humedad y radiación); se calculó la riqueza y la diversidad alfa y se efectuaron análisis multivariados para establecer las relaciones de forófito y líquen y de liquen y condición ambiental. Se registraron 21 especies, agrupadas en ocho familias y 14 géneros; la familia con mayor cobertura fue Arthoniaceae y la de mayor riqueza, Physciaceae; la especie más abundante fue Bacidia spp. El forófito Trichilia pallida presentó la riqueza y la diversidad más altas, en tanto que Cecropia angustifolia fue la especie de liquen más dominante. Las especies de líquenes presentaron preferencia por un solo forófito, excepto Leptogium diaphanum, la cual se registró en dos forófitos. Los parámetros de pH, intensidad lumínica, temperatura y DAP se correlacionaron positivamente con el establecimiento de los líquenes, los cuales registraron una diversidad significativa con el beneficio que ello conlleva para la conservación y el estudio de estos ecosistemas estratégicos de la región andina colombiana.
