Abstract. The epiphytic lichen Letharia vulpina has been commonly sampled in-situ for nitrogen (N) deposition biomonitoring studies but has never before been transplanted for this purpose. In the high-elevation wilderness areas of southern California Letharia vulpina is generally uncommon, making in-situ sampling difficult. In this study, we compared thallus N accumulation between in-situ Letharia vulpina reference samples from the relatively low N deposition environment of the northern Sierra Nevada mountains and Letharia vulpina transplants that were deployed at nine plots of varying climatic and N deposition regimes in the southern Sierra Nevada mountains for 12 months. Survival of transplants was low (33%) and only occurred at the plots within the current range of Letharia vulpina. Transplant N concentrations became higher than those of the reference samples, while transplants that died had a net loss of N. Transplants that survived had strong relationships of N concentrations to N deposition and approached N concentrations of in-situ Letharia vulpina at the same plots. At the same time, reference plot N concentrations in a relatively clean environment increased substantially from early summer 2020 to 2021, presumably in response to extended exposure to smoke from huge wildfires in summer and fall of 2020.

Two resinicolous calicioid fungi, Chaenothecopsis hendersonii and C. minganensis, are described as new to science and three calicioid fungi (Chaenothecopsis formosa, Cryptocalicium blascoi and Microcalicium loraasii) and one calicioid lichen (Calicium episcalaris) are reported as new to North America. In addition, Sphaerophorus tuckermanii is reported as new to eastern North America, Mycocalicium victoriae is reported for the first time in the northwestern United States, and Chaenotheca hygrophila, C. longispora, C. selvae, Chaenothecopsis irregularis, C. perforata, Mycocalicium fuscipes, Phaeocalicium compressulum and Stenocybe major are reported with enhanced North American ranges. Finally, we provide evidence that Microcalicium conversum is a synonym of M. disseminatum and Mycocalicium calicioides is a synonym of M. ravenelii.

The Mniaceae is one of the largest families of mosses, with more than 75 species worldwide, and is one of the most studied families with respect to chromosome numbers, pairing, structural features, and early or late disjunction. In the 1940s a pathbreaking cytotaxonomic study of haploid-diploid species pairs set the stage for further research that explored allopolyploidy, m-chromosomes, and karyology. Here we report chromosome numbers, examined in the course of our studies of allopolyploidy in several genera, for five species of Cinclidium, two of Cyrtomnium, eight of Plagiomnium, one of Pseudobryum, and eight of Rhizomnium and compare our results to earlier published reports. In contrast to most previous studies, we made multiple counts from different geographical regions within the ranges of the species. Five of our 24 counts represent firsts for these species: Cinclidium alaskanum (n = 6 + m), C. minutifolium (n = 6 + m), Plagiomnium curvatulum (n = 12), P. tezukae (n = 6) and Rhizomnium appalachianum (n = 6 + m). Because there have been major changes in the taxonomic treatment of species of Mniaceae beginning with an important revision of the family in 1968, it is critical to attach correct names to earlier reports of chromosome numbers. Moreover, a number of reports based on misidentifications have necessitated reexamination of the original specimens. Finally, we attempt to relate our observations of chromosome karyotypes to recent discoveries based on whole genome sequencing of selected moss species and point out why such studies of the Mniaceae may prove particularly insightful.

Abstract. To further understand calicioid communities and their habitat and substrate requirements, we conducted a study on the Colville National Forest of northeastern Washington State, U.S.A. We hypothesized that calicioid composition would vary depending on age and type of substrate, and that species diversity would be higher on older trees and in older stands, as found by previous research. To test these hypotheses, we searched for calicioids on plots established by the USDA Forest Service's Forest Inventory and Analysis (FIA) program. Because individual trees on FIA plots are tagged, we could relate recorded tree species and age to calicioid composition. We investigated calicioid species diversity in relation to host species; live, dead or burnt trees; and dominant forest type. Our analyses show that calicioid abundance and diversity do increase with tree age. Thuja plicata hosted the highest number of calicioid species in our study and also had the highest rate of occupancy with 70% of all investigated boles inhabited. In an analysis of the effect of forest type (series), we found the Thuja plicata series to host the highest number of species while the Pseudotsuga menziesii series had the lowest number of species. Only 3.4% of burnt trees sampled hosted calicioids while 43.6% of unburnt trees did, suggesting that fire does negatively impact calicioid communities. Three species, Chaenotheca obscura, Chaenothecopsis haematopus, and C. nigra and were found only on snags. Of the 17 species of shrubs sampled, only Alnus, Amelanchier, Salix, and Holodiscus hosted calicioid lichen or fungi. Species that have rarely been reported from Washington include Chaenothecopsis haematopus and C. ochroleuca.
