Cheiromycina ananas is a synonym of Dictyocatenulata alba, a widespread, lichenized, synnematous hyphomycete herewith reported as new for Europe
Abstract and Figures
A relatively common and widespread lichenized, synnematous hyphomycete
collected mainly on the smooth bark of different trees in Central
and Eastern Europe proved to belong to Dictyocatenulata alba. The species
was known from Central and North America and Asia, and is herewith
newly reported from Europe. Cheiromycina ananas, previously known
only from the type collection in the U.S.A., is considered as a new synonym
of D. alba. A description and illustrations are provided to show the
morphological variability of the species.

... For example, Nigropuncta rugulosa was originally described as a lichenized hyphomycete (Hawksworth and Poelt 1986) but subsequently considered to be a lichenicolous fungus specialized on Bellemerea cinereorufescens, on which its infection strongly suppresses the formation of the host apothecia (Hafellner 2012). Alternatively, species believed to be saprotrophic on wood are now recognized to be lichenized, such as Dictyocatenulata alba (Diederich et al. 2008). At the time of its original description (Morris and Finley 1967), D. alba was poorly understood due to the unclear illustrations and was generally considered to be a bark-inhabiting hyphomycete (Seifert et al. 1987). ...
... Both Blarneya hibernica ) and the type species of the genus Sporodochiolichen, S. lecanorinus (Aptroot and Sipman 2011), have been recognized as one anamorph of Tylophoron species . Sporodochia of the taxon Cheiromycina ananas (Aptroot and Schiefelbein 2003) were reinterpreted as representing sessile synnemata corresponding to the widely distributed and polymorphic species Dictyocatenulata alba and therefore synonymized with it (Diederich et al. 2008). The generic concept of Reichlingia was further enlarged by Frisch et al. (2014) incorporating three additional species with ascocarps and with concordant chemistry (perlatolic acid derivatives). ...
... Printzen (2007), studying further the type material, emphasized that an indistinctly enlarged conidiogenous cell is the main diagnostic character for C. petri. In the previous decade, three other species of Cheiromycina have been described: C. globosa from Germany (Aptroot and Schiefelbein 2003), C. ananas from USA (Aptroot and Schiefelbein 2003), later synonymized under Dictyocatenulata alba (Diederich et al. 2008), and C. reimeri from Turkey and Russian Far East (Printzen 2007). However, the most rarely recorded taxon, C. globosa, does not fit the description of the genus and most likely does not belong to Cheiromycina s. str. ...
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.
... The species is found in Korea up to 1250 m elevation. The species is widely distributed in the northern hemisphere(Diederich et al. 2008, Harris & Lendemer 2006, Lendemer & Harris 2004, Morris & Finley 1967, Seifert et al. 1987.Kondratyuk et al. (2017) recently reported the species from Jeju Island. The nearest known localities in East Asia are in Japan(Seifert et al. 1987) and eastern Russia(Diederich et al. 2008). ...

... Formerly known only from one location in Böhmerwald in northern Upper Austria (Diederich et al. 2008), this tiny lichen is easily overlooked. It prefers sheltered trunk bases and roots of old beeches in old-growth forests. ...
The “Fourth checklist of lichen-forming and lichenicolous fungi of Ukraine”, including 2150 accepted scientific names based on published records as well as analysis of current additions are provided. Current additions include 439 taxa newly recorded for Ukraine after the third checklist of lichens of Ukraine by Kondratyuk et al. (2010) and 262 nomenclatural novelties. Annotations to each taxon of 318 newly recorded to Ukraine are provided in the style of the second checklist by Kondratyuk et al . (1998), i.e. data on phytogeographical regions and administrative districts (oblasts) of Ukraine as well as references to published papers are provided. Among current additions 99 taxa were annotated in the Checklist of lichenicolous fungi of Ukraine by Darmostuk and Khodosovtsev (2017) and consequent references to the latter are provided.
The conclusion confirms the earlier recommendation that national checklists of lichens are to be re-published more often than once a decade.
The inventory of lichens, allied fungi, and their parasites in the Ottawa region has grown from 391 in 1988 to 543 today, almost entirely because of the discovery of species overlooked in previous years and the inclusion of fungal parasites. In addition, almost 140 names have changed with reclassifications and re-identifications. These changes are presented here together with a list of synonyms updating the 1988 list. Vouchers are cited for all new records, and notes are presented for many species neither described nor keyed out in easily accessible literature. Reference is made to the new, complete list of lichens and lichenicolous fungi available online. The new checklist includes one species new for North America (Tremella christiansenii); five species and one variety new for Canada (Caloplaca parvula, Caloplaca reptans, Cladonia petrophila, Enchylium tenax var. ceranoides, Leprocaulon adhaerens, and Merismatium peregrinum); four new for Ontario (Caloplaca reptans, Kiliasia tristis, Lempholemma chalazanum, and Rinodina fimbriata); and nine new for Quebec (Arthonia helvola, Arthonia hypobela, Caloplaca parvula, Cladonia petrophila, Lempholemma chalazanum, Leprocaulon adhaerens, Merismatium peregrinum, Rimularia badioatra, and Tremella christiansenii). Although the climate of the region is warming, especially with higher minimum temperatures in winter, the lichen biota has not increased as a result but, in fact, may be threatened by the effects of climate change on the health of the forests and the trees that support lichens. Air quality has improved in recent decades, allowing numerous lichens to again become established in urban areas. Local areas of especially rich lichen diversity can be found on both the Ontario and Quebec sides of the region, and some of these “hot-spots” are mentioned. Other factors influencing the decrease or increase of lichen cover are also discussed.
New data on the lichen flora of the Kologriv Forest Nature Reserve from the cluster Kologrivskiy are provided. The specimens of lichens, lichenicolous fungi and non-lichenized saprophytic fungi were collected from 9 localities mainly in the Sekha River valley in cluster Kologrivskiy in September 2018. Altogether 110 lichen species, 9 non-lichenized saprobic fungi and 2 lichenicolous fungi are recorded for the first time for the nature reserve, including 69 species and 21 genera new for the Kostroma Region. The genus Leptosillia with species L. wienkampii and lichenicolous fungus Opegrapha phaeophysciae are published for the first time for European Russia. Altogether over 20 indicator species and habitat specialists of biologically valuable forests are known from the study area. Moreover 4 species (Leptogium burnetiae, Lobaria pulmonaria, Menegazzia terebrata, Nephromopsis laureri) are included in the Red Data Book of Russia.
New data on the lichen flora of the North Ossetia Nature Reserve from cluster “Shubi” are provided. This cluster is located in Skalistyy and Pastbishchnyy ranges. The specimens of lichens, lichenicolous fungi and non-lichenized saprophytic fungi were collected from 8 localities in cluster “Shubi” in June 2016. In total, 273 lichen species, 4 non-lichenized saprobic fungi and 17 lichenicolous fungi were recorded. Among them 254 species are new for North Ossetia Nature Reserve, 214 species are new for Republic of North Ossetia — Alania, 130 species are new for the Central Caucasus, and 14 species are new for the Caucasus. Bacidina mendax, B. sulphurella, Candelariella boleana, Cryptodiscus tabularum, Halecania elaeiza, H. viridescens, Leptorhaphis maggiana, Verrucaria hegetschweileri were not previously reported from Asia. Nine species are reported for the first time for Russia: Bacidina mendax, Bagliettoa steineri, Candelariella boleana, C. xanthostigmoides, Chaenothecopsis trassii, Halecania elaeiza, H. viridescens, Leptorhaphis maggiana, Verrucaria hegetschweileri.
29 species of lichens, 3 non-lichenized calicioid fungi and 3 lichenicolous fungi are reported for the frst time from the Kostroma Region. Among them, 15 species are new for the Central Federal District, including Myrionora albidula – a rare species with widely scattered locations, previously known only from the Southern Urals Mts in European Russia. The most important discoveries are confined to old-growth coniferous Picea sp. and Abies sibirica forests in the Kologriv Forest Nature Reserve. Two species (Leptogium burnetiae and Menegazzia terebrata) are included in the Red Data Book of Russian Federation. Te distribution, ecology, taxonomic characters and conservation status of rare species and of those new for the Central Federal District are provided.
Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10–15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of ‘Ainsworth & Bisby’s Dictionary of the Fungi’ in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the “Without prejudice list of generic names of Fungi” published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell & Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. & De Not. (Art. 59).
An account of the lichens collected by the participants of the 30th A. Leroy Andrews Foray to
the Delaware Water Gap National Recreation Area is provided. This contribution supplements the report of Water Gap lichens previously compiled by the authors. Bacidia phyllopsoropsis is described as new to science.
Two new synnematous genera of the Fungi Imperfecti are described. Dictyocatenulata, with the type species D. alba, is proposed for the Dictyosporae group and Hyalotrocophora, with the type species H. lignitalis, is proposed for the Helicosporae group of the Stilbellaceae.
A fifth species of Cheiromycina, C. reimeri sp. nov., is described from humid mixed spruce forests of eastern Turkey and on the island of Sakhalin in the Russian Far East. Cheiromycina flabelliformis is reported as new to Turkey, C. petri as new to Russia, Turkey and North America, and a revised key to the species is provided.
A second species of the lichen-forming hyphomycete genus Cheiromycina B. Sutton, C. petri D. Hawksw. & Poelt sp.nov., is described from old Betula bark in Steiermark, Austria. It differs from C. flabelliformis B. Sutton in thallus colour, the more compact blue-grey non-eroding sporodochia, the very tightly dichotomously branched conidia, and in having much shorter terminal branches.
The new genus Cheiromycina, based on the new species C. flabelliformis is described and illustrated from Picea wood in Sweden. It is characterized by eustromatic sporochial conidiomata, a thick-walled branched conidiogenous system and holobastic flabelliform to palmate, hyaline to pale brown, distoseptate conidia. It is compared and contrasted with several similar deuteromycetes, especially on coniferous substrates.
Three remarkable new genera of conidial lichen-forming fungi, with pycnidial or acervular conidiomata are described and illustrated.Hastifera tenuispora gen. et spec. nov. from the South-Tyrol, Italy, is characterized by very long and narrow hyaline conidia produced in pycnidial conidiomata immersed in thalline warts.Lichingoldia gyalectiformis gen. et spec. nov. from rocks subject to inundation by freshwater in Norway has long sigmoidly curved conidia which appear to be adapted to dispersal in water.Woessia fusarioides gen. et spec. nov. from aQuercus stump in the Burgenland, Austria, has a finely granular thallus and disc-like conidiomata producing falcate conidia; this species is also of interest in that it hasChlorella as the photobiont. The recently described hyphomyceteCheiromycina flabelliformis
B. Sutton is reported from Austria for the first time, and is also lichenized. Recent collections ofNigropuncta rugulosa
D. Hawksw. from Austria and Italy also show that this species is lichenized rather than parasymbiotic. In all five cases the fungal hyphae of the conidiogenous structures are continuous with those in intimate contact with cells of the algal partners and the biological relationship appears to be mutualistic giving rise to stable crustose lichen thalli.
Cheiromycina globosa and C. ananas spp. nov. are described in the lichenized hyphomycete genus Cheiromycina, one from Germany and one from the USA. A key is provided to all four species now known in genus, and all other lichenized hyphomycetes are briefly mentioned. All are corticolous and rarely recorded, so far only from temperate regions in Europe and North America.
