However, the genus Kalbionora , which has been postulated to belong to Malmideaceae (Sodamuk et al 2017), did not cluster with this family in our phylogenetic analyses. Many more lichen-forming genera and species need to be sampled to paint a more complete picture of phylogenetic relationships in Malmideaceae .…”

“…Despite the lacunose sequence coverage, we recovered the Malmideaceae as a well-supported, monophyletic clade including L. albofuscescens as well as Lecidea malmeana , a polysporous species collected in GLBA. Of species that have been previously reported to belong to Malmideaceae , only Kalbionora (Sodamuk et al 2017) was not recovered within this clade, instead grouping in an unsupported relationship with the outgroup Rhizocarpon . We refrain from undertaking any nomenclatural changes because of poor internal support within Malmideaceae , and ongoing studies.…”

Lichens and associated fungi from Glacier Bay National Park, Alaska

Lichens are widely acknowledged to be a key component of high latitude ecosystems. However, the time investment needed for full inventories and the lack of taxonomic identification resources for crustose lichen and lichenicolous fungal diversity have hampered efforts to fully gauge the depth of species richness in these ecosystems. Using a combination of classical field inventory and extensive deployment of chemical and molecular analysis, we assessed the diversity of lichens and associated fungi in Glacier Bay National Park, Alaska (USA), a mixed landscape of coastal boreal rainforest and early successional low elevation habitats deglaciated after the Little Ice Age. We collected nearly 5000 specimens and found a total of 947 taxa, including 831 taxa of lichen-forming and 96 taxa of lichenicolous fungi together with 20 taxa of saprotrophic fungi typically included in lichen studies. A total of 98 species (10.3% of those detected) could not be assigned to known species and of those, two genera and 27 species are described here as new to science: Atrophysma cyanomelanos gen. et sp. nov., Bacidina circumpulla, Biatora marmorea, Carneothele sphagnicola gen. et sp. nov., Cirrenalia lichenicola, Corticifraga nephromatis, Fuscidea muskeg, Fuscopannaria dillmaniae, Halecania athallina, Hydropunctaria alaskana, Lambiella aliphatica, Lecania hydrophobica, Lecanora viridipruinosa, Lecidea griseomarginata, L. streveleri, Miriquidica gyrizans, Niesslia peltigerae, Ochrolechia cooperi, Placynthium glaciale, Porpidia seakensis, Rhizocarpon haidense, Sagiolechia phaeospora, Sclerococcum fissurinae, Spilonema maritimum, Thelocarpon immersum, Toensbergia blastidiata and Xenonectriella nephromatis. An additional 71 ‘known unknown’ species are cursorily described. Four new combinations are made: Lepra subvelata (G. K. Merr.) T. Sprib., Ochrolechia minuta (Degel.) T. Sprib., Steineropsis laceratula (Hue) T. Sprib. & Ekman and Toensbergia geminipara (Th. Fr.) T. Sprib. & Resl. Thirty-eight taxa are new to North America and 93 additional taxa new to Alaska. We use four to eight DNA loci to validate the placement of ten of the new species in the orders Baeomycetales, Ostropales, Lecanorales, Peltigerales, Pertusariales and the broader class Lecanoromycetes with maximum likelihood analyses. We present a total of 280 new fungal DNA sequences. The lichen inventory from Glacier Bay National Park represents the second largest number of lichens and associated fungi documented from an area of comparable size and the largest to date in North America. Coming from almost 60°N, these results again underline the potential for high lichen diversity in high latitude ecosystems.

“…In fact, only recently the genera Crustospathula, Kalbionora , and Sprucidea have been recognized to be part of Malmideaceae (Cáceres et al 2017; Sodamuk et al 2017), in addition to the originally included species of Malmidea, Savonorala , and two taxa of Lecidea s. lat.

Molecular analyses uncover the phylogenetic placement of the lichenized hyphomycetous genusCheiromycina

et al. 2017

View full text Add to dashboard Cite

The genus Cheiromycina is one of the few genera of lichenized hyphomycetes for which no sexual reproductive stages have been observed. The genus includes species from boreal to temperate regions of the Northern Hemisphere where it is found growing on bark or wood. Congeners in Cheiromycina are characterized by a noncorticate thallus, nearly immersed in the substrate and presenting powdery unpigmented sporodochia, and containing chlorococcoid photobionts. The relationships of members of Cheiromycina with other fungi are not known. Here we inferred the phylogenetic placement of Cheiromycina using three loci (nuSSU, nuLSU, and mtSSU) representing C. flabelliformis, the type species for the genus, C. petri, and C. reimeri. Our results revealed that the genus Cheiromycina is found within the family Malmideaceae (Lecanorales) where members formed a monophyletic clade sister to the genera Savoronala and Malmidea. This phylogenetic placement and the relationships of Cheiromycina with other lichenized hyphomycetous taxa are here discussed.

“…However, recent studies on the Malmideaceae have indicated that the ascus and ascospore structures vary between the different genera (Cáceres & al., 2017). The family Malmideaceae has lately been investigated in more detail and several new genera have been described (Cáceres & al., 2017;Muggia & al., 2017;Sodamuk & al., 2017). Further molecular studies with a dataset including sequences of all known Malmideaceae genera are necessary to find out whether all species from clade A belong into this family and whether they form distinct genera.…”

The Ramalinaceae is the fourth-largest family of lichenized ascomycetes with 42 genera and 913 species exhibiting considerable morphological variation. Historically, generic boundaries in the Ramalinaceae were primarily based on morphological characters. However, molecular systematic investigations of subgroups revealed that current taxonomy is at odds with evolutionary relationships. Tropical members of the family remain particularly understudied, including the large genus Phyllopsora. We have generated and collected multilocus sequence data (mtSSU, nrITS, nrLSU, RPB1, RPB2) for 149 species associated with the Ramalinaceae and present the first comprehensive molecular phylogeny of the family. We used ancestral state reconstructions on our molecular family phylogeny to trace the evolution of character states. Our results indicate that the Ramalinaceae have arisen from an ancestor with long, multiseptate ascospores living in humid temperate forests, and that the phyllopsoroid growth form has evolved multiple times within the family. Based on our results using integrative taxonomy, we discuss sister-relations and taxon-delimitation within five well-supported clades: The Bacidia, Biatora-, Ramalina-, Rolfidium-, and Toninia-groups. We reduce six genera into synonymy and make 49 new nomenclatural combinations. The genera Bacidia, Phyllopsora, Physcidia and Toninia are polyphyletic and herein split into segregates. We describe the two genera Bellicidia and Parallopsora and resurrect the genera Bibbya, Kiliasia, Sporacestra, and Thalloidima. According to our new circumscription, which also includes some additional changes, the family Ramalinaceae now comprises 39 genera.
