“…Our analyses support previous studies Wiklund & Wedin, 2003;Myllys & al., 2005) that Heterodea belongs to Cladoniaceae and is closely related to Cladia. Interestingly, a close relationship between Cladia and Heterodea has not been raised in the literature, with the notable exception of Poelt (1974), who wrote "The foliose Heterodea … may be related to Cladia."…”

Phylogenetic relationships of the genera Cladia and Heterodea were reconstructed using a combined dataset of nuclear ITS, nuclear LSU and mitochondrial SSU rDNA sequences. Based on different analyses (Bayesian approach, maximum parsimony, maximum likelihood), the ingroup (Cladia + Heterodea) is strongly supported as monophyletic. Pilophorus strumaticus has a well supported sister–group relationship to the ingroup and together they form a sister group with a well–supported clade, which includes Metus conglomeratus and Pycnothelia papillaria. The Shimodaira–Hasegawa test and the ELW test significantly rejected monophyly of Cladia excluding Heterodea. Within Cladia three main clades can be distinguished which share morphological and chemical characters. The position of the foliose genus Heterodea within the fruticose Cladia is supported by anatomical and chemical characters. The species of clade II that includes two Cladia species and Heterodea share a similar type of upper cortex and two–layered medulla with an inner or lower medulla consisting of dark pigmented, thick–walled hyphae. Our phylogenetic estimate and the anatomical studies indicate that the foliose thallus of Heterodea originated from pseudopodetia of Cladia. It is discussed that the species currently classified in Cladia and Heterodea need to be placed in the same genus.

“…These results are in accordance with a previous analysis based on nuSSU sequences showing that Solorina is located in the Hydrothyria-Peltigera clade and is a sister-clade to Peltigera with 100% bootstrap support [23]. Also, when using mtSSU and nuLSU sequences, S. crocea and Massalongia calrosa were closely related to Peltigera with very high support values [33].…”

23An algific talus slope is composed of broken rocks with vents connected to an ice cave, 24 releasing cool air in summer and relatively warmer air in winter to maintain a more stable 25 microclimate all year round. Such geological features create a very unusual and delicate 26 ecosystem. Although there are around 25 algific talus slopes in Korea, lichen ecology of these 27 areas had not been investigated to date. In this study, we report the first exploration of lichen 28 ecology at an algific talus slope, Jangyeol-ri, in Korea. A total of 37 specimens were collected 29 over 2017-2018. Morphological and sequencing analysis revealed 27 species belonging to 18 30 genera present in the area. Of particular interest among these species was Solorina saccata, as 31 it has previously not been reported in Korea and most members of genus Solorina are known 32 to inhabit alpine regions of the Northern Hemisphere. We provide here a taxonomic key for S. 33 saccata alongside molecular phylogenetic analyses and prediction of potential habitats in South 34 Korea. Sequences were generated from all S. saccata specimens collected in this study, 35 together with three S. saccata specimens from China for comparison. Phylogenetic analysis 36 based on nuclear small subunit (nuSSU) showed that all the S. saccata specimens are tightly 37 grouped into one clade with high support values (P=0.99) and showed close relatedness to S. 38 spongiosa than S. crocea. Additional analyses were carried out using concatenated sequences: 39 65 sequences of mitochondrial small subunit (mtSSU) combined with nuLSU and 66 sequences 40 of RPB1 with nuLSU. In these analyses, genus Peltigera was found to be the closest genus to 41 S. saccata. Furthermore, regions in South Korea potentially suitable for Solorina spp. were 42 predicted based on climatic features of known habitats around the globe. Our results showed 43 that the suitable areas are mostly at high altitudes in mountainous areas where the annual 44 temperature range doesn't exceed 26.6˚C. Further survey of other environmental conditions Park et al. 3 45 determining the suitability of Solorina spp. should lead to a more precise prediction of suitable 46 habitats and trace the origin of Solorina spp. in Korea. 47

“…(2002b), closely related to Heterodea and Ramalea. It should be noted, however, that in the combined analysis of mt SSU rDNA and LSU rDNA sequences, Pilophorus grouped together with Stereocaulon and Cladoniaceae was not resolved as monophyletic (Wiklund & Wedin, 2003). This conflicting result can perhaps be explained by the more limited taxon sampling of Wiklund & Wedin (2003).…”

“…The reclassification of Stereocaulaceae was further supported by mitochondrial SSU rDNA data, which placed Pilophorus as a sistergroup to Cladonia and Metus. However, in the combined analysis of mitochondrial SSU rDNA and nuclear LSU rDNA data, Pilophorus and Stereocaulon formed a mono-phyletic group (Wiklund & Wedin, 2003).…”

The phylogenetic relationships of the lichenised ascomycete family Stereocaulaceae were investigated with partial beta‐tubulin, partial glyceraldehyde 3‐phosphate dehydrogenase (GAPDH) and SSU rDNA sequence data. Due to the marked length variation in the SSU rDNA sequences, the analyses were performed with direct optimization. The combined analysis of the beta‐tubulin, GAPDH and SSU rDNA sequences as well as the separate analyses of beta‐tubulin and GAPDH data recognized the monophyletic group comprising Lepraria, Muhria and Stereocaulon. In the combined analysis Stereocaulon tornense appears as a basal taxon in the Stereocaulon clade, suggesting that the crustose growth form and the absence of cephalodia are primitive features within the genus. Muhria is nested in Stereocaulon and groups with the crustose S. cumulatum and S. leucophaeopsis. The genus Lepraria is monophyletic if Leproloma is included, but species that were represented by several specimens in our study, i.e., Lepraria jackii and Leproloma membranaceum, do not appear as monophyletic entities. The genus Pilophorus is included in Cladoniaceae. Combined analysis of the three datasets clearly led to an increase in support values compared to the separate analyses, showing high support for the monophyly of families Cladoniaceae and Stereocaulaceae and for the sistergroup relation for the two families. The relationships between higher groupings did not reach high support values probably due to the incongruencies among the three datasets.
