“…The measurements under field conditions showed a pronounced diurnal pattern in the coarse mode with the highest concentrations during nighttime, which has already been reported for other fungal species (Fernando et al, 2000;Gilbert and Reynolds, 2005;Stensvand et al, 1998). Aerosol and trace gas concentrations frequently have been shown to also display diurnal and seasonal patterns (Gadoury et al, 1998;Huffman et al, 2012a;Moran-Zuloaga et al, 2018;Pöhlker et al, 2012;20 Yáñez-Serrano et al, 2015).…”

“…2). Combined with micro-morphological details of the 5 hymenium and basidiospores, the species was identified as Rigidoporus microporus (Polyporales, Basidiomycota), which has already been reported for the Amazon area (Gomes-Silva et al, 2014). In the results section, the exemplary measurements made with the model species are presented.…”

“…In earlier studies, a vertical structure of aerosols within the canopy was shown in the tropics (Gilbert and Reynolds, 2005), which could be investigated by utilizing this method to monitor the organisms at varying canopy heights. If the results of spore emission experiments are coupled with an inventory of cryptogams, very promising insights might be achieved.…”

“…They can influence the water cycle by acting as cloud condensation or ice nuclei, thereby triggering precipitation (Möhler et al, 2007;Pöschl et al, 2010) and they can affect the radiative budget of the atmosphere, by the absorption and scattering of radiation, on a local and global scale (Cox, 1995). 25 Although the general knowledge on PBAP is still sparse, there are several studies on the sampling and sizing of PBAP in the Amazon (Elbert et al, 2007;Gilbert and Reynolds, 2005;Graham et al, 2003;Huffman et al, 2012b;Moran-Zuloaga et al, 2018;Pöschl et al, 2010;Whitehead et al, 2016;Womack, 2015). However, a large variety of techniques has been utilized in these aerosol sampling studies, which handicaps their direct comparability.…”

Bioaerosols are considered to play a relevant role in atmospheric processes, but their sources, properties and spatiotemporal distribution in the atmosphere are not yet well characterized. In the Amazon Basin, primary biological aerosol particles (PBAP) account for a large fraction of coarse particulate matter, and fungal spores are among the most abundant PBAP there as well as in other vegetated continental regions. Furthermore, PBAP could also be important ice nuclei in Amazonia. Measurement data on the release of fungal spores under natural conditions, however, are sparse. Here we present 5 an experimental approach to analyze and quantify the spore release from fungi and other spore producing organisms under natural and laboratory conditions. For measurements under natural conditions, the samples were kept in their natural environment and a setup was developed to estimate the spore release numbers and sizes together with the microclimatic factors temperature and air humidity, as well as the mesoclimatic parameters net radiation, rain, and fog occurrence. For experiments in the laboratory, we developed a cuvette to assess the particle size and number of newly released fungal spores under 10 controlled conditions, simultaneously measuring temperature and relative humidity inside the cuvette. Both approaches were combined with bioaerosol sampling techniques to characterize the released particles by microscopic methods. For fruiting bodies of the basidiomycetous species, Rigidoporus microporus, the model species for which these techniques were tested, the highest frequency of spore release occurred in the range of 62 and 96 % relative humidity. The results obtained for this model species reveal characteristic spore release patterns linked to environmental or experimental conditions, indicating that the 15 moisture status of the sample may be a regulating factor, while temperature and light seem to play a minor role for this species.The presented approach enables systematic studies aimed at the quantification and validation of spore emission rates and inventories, which can be applied to a regional mapping of cryptogamic organisms under given environmental conditions. 1 of bioaerosol emissions, which is roughly 23 % of total primary organic aerosol emission (Fröhlich-Nowoisky et al., 2016; Graham et al., 2003; Heald and Spracklen, 2009; Jacobson and Streets, 2009;Sesartic et al., 2013).Species of Polyporales (Basidiomycota), the order of the model species of the present study, mostly colonize dead wood, 30where they form vegetative hyphae degrading the wood. On the surface of dead wood they form fruiting bodies with pores located at their lower side. The surface of these pores is covered by a hymenium, where basidiospores are produced on basidia.Each basidium externally forms mostly four asymmetrical basidiospores on little curved, tapering stalks, called sterigmata.The spores are fixed to the sterigmata at the hilum, which thus forms a characteristic feature of basidiospores.

The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406–430 Mya, classes are 211–383 Mya, and orders are 99–323 Mya, which are largely consistent with previous studies. In this study, all phylogenetically supported families were dated, with the families of Agaricomycotina diverging from 27–178 Mya, Pucciniomycotina from 85–222 Mya, and Ustilaginomycotina from 79–177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of their phylogeny and evolution.
