Pyrenocarpous lichens are an important component of the forest ecosystem, yet remain understudied. Following the recent field surveys of the lichen biota in Mt. Musuan, four pyrenolichen species previously unreported from the Philippines were collected, namely: Porina exocha, Pyrenula pyrenuloides, P. subsoluta, and Nigrovothelium inspersotropicum. Each species is briefly described with morphology and chemistry, distribution, ecology, notes, and illustrations. These collections underscore the need for expanded research attention to fully catalogue the lichen diversity in the Philippines.

Lichens across Land Use Types of Mt. Musuan, Bukidnon, Southern Philippines
Explorations on the knowledge and biodiversity of Philippine lichen fungi have progressed recently. However, comparatively little attention has been given to the species composition along a lowland secondary forest ecosystem. Thus, the study aimed to provide information on the occurrence of lichen species in relation to various land use types of Mt. Musuan of Mindanao Island, surrounded by forest fragments and cultivated agricultural areas. A series of transect walks and opportunistic sampling revealed a total of 38 lichen species distributed in 26 genera and 14 families. Among the land use types, the mixed species forest harbors the highest recorded species with 22, followed by teak forest and built-up (peak/summit) with 15 and 14 species, respectively. Lichens with the most represented families were revealed to be Graphidaceae with 10 species; Caliciaceae with six species; Physciaceae, Parmeliaceae, and Arthoniaceae with three species each; and Pyrenulaceae, Collemataceae, Letrouitiaceae, and Trypetheliaceae with two species each. Out of these collections, two species – viz. Letrouitia subvulpina (Nyl.) Hafellner and Pyrenula globifera (Eschw.) Aptroot – were new records in the Philippines. The results of this study will provide information to encourage effective management and biodiversity conservation efforts of various land use types, as lichens are sensitive to anthropogenic threats and pressures from environmental conditions.

Abstract. Forty years ago, lichens were identified as extraordinary biological icenucleators (INs) that enable ice formation at temperatures close to0 ∘C. By employing INs, lichens thrive in freezing environmentsthat surpass the physiological limits of other vegetation, thus making themthe majority of vegetative biomass in northern ecosystems. Aerosolizedlichen INs might further impact cloud glaciation and have the potential toalter atmospheric processes in a warming Arctic. Despite the ecologicalimportance and formidable ice nucleation activities, the abundance,diversity, sources, and role of ice nucleation in lichens remain poorlyunderstood. Here, we investigate the ice nucleation capabilities of lichenscollected from various ecosystems across Alaska. We find ice nucleatingactivity in lichen to be widespread, particularly in the coastal rainforestof southeast Alaska. Across 29 investigated lichen, all species show icenucleation temperatures above −15 ∘C, and ∼30 %initiate freezing at temperatures above −6 ∘C. Concentrationseries of lichen ice nucleation assays in combination with statisticalanalysis reveal that the lichens contain two subpopulations of INs, similarto previous observations in bacteria. However, unlike the bacterial INs, thelichen INs appear as independent subpopulations resistant to freeze–thawcycles and against temperature treatment. The ubiquity and high stability ofthe lichen INs suggest that they can impact local atmospheric processes andthat ice nucleation activity is an essential trait for their survival incold environments.more » « less

We assess the identification accuracy of ‘research grade’ observations of lichens posted on the online platform iNaturalist. Our results show that these observations are frequently misidentified or lack the necessary chemical and (or) microscopic information for accurate identification. Lichens are a taxonomically difficult group, but they are ubiquitous and eye-catching and are regularly the subject of observations posted on iNaturalist. Therefore, we provide best practice recommendations for posting lichen observations and commenting on observations. Data from iNaturalist are a valuable tool for understanding and managing biodiversity, particularly at this crucial time when large scale biodiversity decline is occurring globally. However, the data must be accurate for them to effectively support biodiversity conservation efforts. Our recommendations are also applicable to other taxonomically difficult taxa.more » « less

The National Ecological Observatory Network (NEON) is gathering select ecological and taxonomic data across 81 sites in the United States and Puerto Rico. Lichens are one of the organismal groups that NEON has not yet assessed across these sites. Here we sampled lichens at Ordway-Swisher Biological Station (OSBS), a NEON site in north central Florida, to provide a baseline survey of the commonly encountered macrolichens (foliose, fruticose, and squamulose lichens). Macrolichens represent a subset of observable lichens and are more commonly surveyed than crustose lichens. Seventy-four species of macrolichens were collected, including 25 occurrences that constitute new records for Putnam County, Florida. The lichen diversity at OSBS comprised approximately 30% of the macrolichen diversity known from the entire state of Florida. Fifty-four taxa are common in the state of Florida, 12 infrequent across the state, and eight are considered rare. Macrolichens were the seventh most species-rich taxonomic groups at OSBS and more diverse than the NEON focal groups of mammals and fish. Lastly, we suggest a theoretical roadmap for how lichenologists could work together with NEON to include lichens in future datasets. We hope that biologists focused on other key organismal groups will sample in NEON sites so that NEON data can be leveraged appropriately in future cross-taxon studies of biodiversity at the continental scale.more » « less

Herbivory by terrestrial gastropods, particularly Arion sp., can alter lichen communities; however, little is known about this interaction in forests of North America. This data set reports the results of two feeding trials with slugs and snails from Hubbard Brook on seven lichen species. In feeding trials two common lichens, Hypogymnia physodes and Platismatia glauca, were grazed more heavily by both native and non-native slugs than other lichen species.more » « less
