    Remarkable cases of parallel evolution of the placodioid thallus growth form in the Lecanographaceae (Arthoniales) with the description of a new species of Alyxoria from MexicoIn: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135Article in journal (Refereed)
    Abstract [en]

    The new species Alyxoria sierramadrensis is described from Mexico where it inhabits limestone rocks. The lichen developing from this fungus is characterized by a placodioid to subfoliose thallus with a white pruinose surface; rounded to shortly elongated ascomata with a black epruinose margin and a widely exposed, white pruinose hymenial disc; hyaline, 3-septate ascospores,17–25 × 7–9 μm; the presence of anthraquinones rendering the medulla orange. Phylogenetic analyses of nuLSU, mtSSU and RPB2 sequences place this species in the genus Alyxoria (Lecanographaceae). This generic affiliation is surprising because all known Alyxoria species have a crustose thallus. Lecanographaceae mainly includes species without a thallus (lichenicolous taxa) or with a thin crustose thallus, the only exception being Simonyella variegata with a fruticose thallus. The new species belongs to the Alyxoria ochrocheila subgroup, which includes lichens also frequently known to have anthraquinones, white pruinose hymenial discs and 3-septate ascospores. Phylogenetic analyses further determined the systematic position of the monotypic genus Phoebus. This genus, considered as an Arthoniales of uncertain family affiliation, is shown to belong to the Lecanographaceae. With its placodioid thallus, it is another example of a lichenized fungus with a deviating morphology in thallus structure for the family, increasing the number of remarkable cases of parallel evolution of lichen growth forms within the Arthoniales. Phoebus hydrophobius is newly recorded for Mexico.

    Fossilized fungi in subseafloor Eocene basalts.2012In: Geology, ISSN 0091-7613, Vol. 40, no 2, p. 163-166Article in journal (Refereed)
    Abstract [en]

    The deep biosphere of subseafl oor basalts is thought to consist of mainly prokaryotes (bacteria and archaea). Here we report fossilized fi lamentous microorganisms from subseafl oor basalts interpreted as fossilized fungal hyphae, probably Dikarya, rather than fossilized prokaryotes. The basalts were collected during the Ocean Drilling Program Leg 197 at the Emperor Seamounts, North Pacifi c Ocean, and the fossilized fungi are observed in carbonate-fi lled veins and vesicles in samples that represent a depth of ~150 m below the seafl oor. Three-dimensional visualizations using synchrotron-radiation X-ray tomographic microscopy show characteristic fungal morphology of the mycelium-like network, such as frequent branching, anastomosis, and septa. Possible presence of chitin in the hypha walls was detected by staining with Wheat Germ Agglutinin conjugated with Fluorescein Isothiocyanate and examination using fl uorescence microscopy. The presence of fungi in subseafl oor basalts challenges the present understanding of the deep subseafl oor biosphere as being exclusively prokaryotic.

    Zygomycetes in Vesicular Basanites from Vesteris Seamount, Greenland Basin - A New Type of Cryptoendolithic Fungi2015In: PLoS One, Vol. 10, article id e0133368Article in journal (Refereed)
    Abstract [en]

    Fungi have been recognized as a frequent colonizer of subseafloor basalt but a substantial understanding of their abundance, diversity and ecological role in this environment is still lacking. Here we report fossilized cryptoendolithic fungal communities represented by mainly Zygomycetes and minor Ascomycetes in vesicles of dredged volcanic rocks (basa- nites) from the Vesteris Seamount in the Greenland Basin. Zygomycetes had not been reported from subseafloor basalt previously. Different stages in zygospore formation are documented in the studied samples, representing a reproduction cycle. Spore structures of both Zygomycetes and Ascomycetes are mineralized by romanechite-like Mn oxide phases, indicating an involvement in Mn(II) oxidation to form Mn(III,VI) oxides. Zygospores still exhibit a core of carbonaceous matter due to their resistance to degradation. The fungi are closely associated with fossiliferous marine sediments that have been introduced into the vesicles. At the contact to sediment infillings, fungi produced haustoria that penetrated and scavenged on the remains of fragmented marine organisms. It is most likely that such marine debris is the main carbon source for fungi in shallow volcanic rocks, which favored the establishment of vital colonies.

    The strange case of Ocellomma rediuntum (Arthoniales: Roccellaceae) in Australia: a remarkably disjunct lichen2020In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 52, p. 187-195Article in journal (Refereed)
    Abstract [en]

    The new combination Ocellomma rediuntum (Stizenb. ex Hasse) Kantvilas, Gueidan & Tehler is proposed, supported by morphological, anatomical and molecular data. Hitherto known only from the Californian coast, this species is here recorded for Kangaroo Island (South Australia), Victoria and Tasmania. It is described and illustrated from Australian collections. The ecology of the species and its remarkable distribution are discussed.

    Roccella ramitumidula (Roccellaceae), a new species from the tropical dry forest of Mexico2022In: Bryologist, Vol. 125, no 3, p. 477-484Article in journal (Refereed)
    Abstract [en]

    The new species Roccella ramitumidula is described from a tropical dry forest in the Pacific Coast of Mexico. The new species is characterized by fertile thalli, saxicolous habit, irregularly swollen branches and erythrin and lecanoric acid as lichen products. It differs from R. decipiens by its narrower and longer ascospores, irregularly swollen branches, uneven surface, and smaller branches. Sequences of the genetic markers ITS, nuLSU and RPB2 from the new species were added to a phylogenetic tree based on four genetic markers that included all the Roccella species known for the Americas. The biogeography and ecology of the species is discussed. We reported R. gracilis for the first time for the state of Jalisco, Mexico.

    Biatora akompsa is found to be a disjunct North American species of Pentagenella (Opegraphaceae) through Molecular Phylogenetic Analysis2020In: The Bryologist, ISSN 0007-2745, E-ISSN 1938-4378, Vol. 123, no 3, p. 502-516Article in journal (Refereed)
    Abstract [en]

    Historical and recent material of Bacidia akompsa (basionym: Biatora akompsa) was studied to determine the taxonomic position of this crustose lichen, prompted by the appearance of the provisional name ‘‘Lecanactis akompsa (Tuck.) ined.’’ in multiple online lichen databases and checklists. Initial morphological assessment of verified material confirmed B. akompsa as a member of Arthoniales but distinct from Lecanactis by having epruinose ascomata with a thin exciple open below the hymenium; a pale, K/Iþ violet to deep blue hypothecium; and ascospores with a gelatinous sheath. Molecular phylogenetic analysis of specimens recently collected near the type locality revealed B. akompsa to be nested within the genus Pentagenella in Opegraphaceae. The same placement was found using phenotype-based phylogenetic binning with 37 morphological, anatomical and chemical characters. The new combination Pentagenella akompsa is proposed and the species represents the first North American member of this genus, otherwise known only from Chile and Peru. Therefore, our results reveal the genus Pentagenella to have a remarkably disjunct distribution between North and South America. Several specimens previously labeled as Bacidia, Biatora, or Lecanactis akompsa were found to be misidentifications, narrowing the range of P. akompsa to coastal California, where it is found on two coastal conifer species that are (like P. akompsa itself) narrowly endemic and of conservation concern.

    Trimmatostroma rouxii Diederich, Tehler & van den Boom sp. nov. - In: Diederich, Paul (2021) Notes on lichenicolous taxa of the asexual fungal genera Intralichen and Trimmatostroma, with a revised key and descriptions of four new species.2021In: Herzogia, Vol. 34, no 1, p. 111-111Article in journal (Refereed)
    Abstract [en]

    The genus Intralichen comprises several mainly intrahymenial lichenicolous species of unknown phylogenetic affini- ties, each reported from a very large host-spectrum, with many reports obviously representing wrong identifications. We suggest restricting the use of each of these species names to collections growing on the same host genus as the type specimen, i.e., all other reports from different hosts are considered uncertain. Intralichen christiansenii is considered as a synonym of I. lichenicola, a species confined to Candelariella species. Intralichen lichenum s. str. is a poorly known and rarely collected species from Arthoniales hosts, while similar populations on Strangospora are treated as I. aff. lichenum. Intralichen baccisporus has not been revised, as sufficient material from the many Teloschistaceae gen- era was not available. Morphologically similar species growing on the thalli, not in the hymenium, of various lichen hosts are included in the genus Trimmatostroma, although most lichenicolous species do not seem to be related to the generic type. The new species Trimmatostroma acetabuli (on Pleurosticta acetabulum), T. denigrans (on Lecanora horiza), T. rouxii (on Opegrapha durieui and other saxicolous Arthoniales) and T. vandenboomii (on Myriolecis al- bescens) are described. Fertile material of T. arctoparmeliae has been studied, with the result that this species is combined as Sphaerellothecium arctoparmeliae. A revised key to all known lichenicolous species of Intralichen and Trimmatostroma is given.
