“…These four orders contain most reads of the data set; together they account for 79% of the ITS1 data set and a 36% of the unfiltered data set, which in turn contains a 23% of unidentified sequences vs. the 6.6% of the ITS1 data set. The fact that most known lichenicolous species (Lawrey & Diederich, 2017;Prillinger et al, 1997) also belongs in these orders suggests that many unidentified MOTUs may reflect the presence of asymptomatic lichenicolous fungi other than those targeted in our survey.…”

As self-supporting and long-living symbiotic structures, lichens provide a habitat for many other organisms beside the traditionally considered lichen symbionts-the myco- and the photobionts. The lichen-inhabiting fungi either develop diagnostic phenotypes or occur asymptomatically. Because the degree of specificity towards the lichen host is poorly known, we studied the diversity of these fungi among neighbouring lichens on rocks in an alpine habitat. Using a sequencing metabarcoding approach, we show that lichen mycobiomes clearly reflect the overlap of multiple ecological sets of taxa, which differ in their trophic association with lichen thalli. The lack of specificity to the lichen mycobiome is further supported by the lack of community structure observed using clustering and ordination methods. The communities encountered across samples largely result from the subsampling of a shared species pool, in which we identify three major ecological components: (i) a generalist environmental pool, (ii) a lichenicolous/endolichenic pool and (iii) a pool of transient species. These taxa majorly belong to the fungal classes Dothideomycetes, Eurotiomycetes and Tremellomycetes with close relatives in adjacent ecological niches. We found no significant evidence that the phenotypically recognized lichenicolous fungi influence the occurrence of the other asymptomatic fungi in the host thalli. We claim that lichens work as suboptimal habitats or as a complex spore and mycelium bank, which modulate and allow the regeneration of local fungal communities. By performing an approach that minimizes ambiguities in the taxonomic assignments of fungi, we present how lichen mycobiomes are also suitable targets for improving bioinformatic analyses of fungal metabarcoding.

“…It has been suggested that secondary metabolites prevent degradation of lichen thalli by fungal, bacterial or other organisms. Nevertheless, lichens host diverse other fungi, both phenotypically conspicuous as well as poorly classified epi-and endobionts (e.g., Lawrey and Diederich, 2003;Petrini et al, 1990;Prillinger et al, 1997).…”

“…1). The result showed that five isolates were in a cluster and closely related with Fellomyces chinensis (Prillinger et al, 1997), F. distylii (Hamamoto et al, 1998), F. lichenicola, F. sichuanensis (Prillinger et al, 1997, and Kockovaella schimae.…”
