Acarospora crozalsii (Lichenized Ascomycetes, Acarosporaceae), to be reinstated in the Italian lichen flora Abstract Knudsen, K., Kocourková J. & Nimis, P. L.: Acarospora crozalsii (Lichenized Ascomycetes, Acarosporaceae), to be reinstated in the Italian lichen flora.-Borziana 5: 41-45. 2024.-ISSN: 2724-5020 online. Some samples collected in Liguria by Camillo Sbarbaro and identified as Acarospora crozalsii, a species which in the past was often synonymised with A. complanata, were analysed. The species, for which a description is provided, is a Mediterranean silicicolous lichen, known from North Africa (Algeria), southern France and Italy. It differs from the similar A. helvetica in the euamyloid hymenial gel and the thinner parathecium, and should be reinstated in the list of lichens known from Italy.

... Environmental modifications have been over-emphasized by some authors (e.g. Weber 1968, Clauzade & Roux 1981, leading to lumping and underestimating diversity. While some species are especially polymorphic (such as A. fuscata and A. glaucocarpa), phylogenetic analysis has generally vindicated the detailed morphological and anatomical analyses pioneered by Magnusson (Knudsen et al. 2020). ...
... Schaereria cinereorufa has similar squamules that could be mistaken for those of an Acarospora, but is readily identified by the open discs of the apothecia and the larger, subglobose ascospores; the C+ pink thallus reaction is variable, even within individual specimens of Schaereria.

... Citation of the former name clearly linked it to the latter and strongly suggests that they intended to treat Magnusson's infraspecific taxon at the species level using Harmand's original unpublished manuscript name. Although Clauzade and Roux (1981) likely did not intend to introduce a nomenclatural novelity in their treatment, their publication must be treated as an attempt at a combination and status novum. This change was however, invalid under Art. ...
... Later, Roux et al. (2014) attempted to combine the epithet into the genus Myriospora, but in doing so only cited "Acarospora fulvoviridula Harm. in sched." rather than the basionym published by Magnusson (1929) or the invalid treatment at the species level by Clauzade and Roux (1981). The new combination Myriospora is also invalid under Art. ...
... However, those authors were probably referring to specimens identified by H. Magnusson as A. smaragdula var. lesdainii forma fulvoviridula (Magnusson 1929) and a suite of specimens collected by Hans Ulrich in Germany that were annotated by Roux in 1982(cited in Wirth et al. 2013. ...
Acarospora smaragdula var. lesdainii forma fulvoviridula is lectotypified and synonymized with Myriospora scabrida. The use of the epithet at the species level as A. flavoviridula is shown to be illegitimate, as is the combination into Myriospora.
... Nonetheless due to the poor quality of Magnusson's keys and many of his descriptions, many taxa of Acarosporaceae are hard or impossible to identify. In Europe, the taxonomy of Clauzade and Roux compounded the problems of identification of specimens in Europe through the introduction of many broad artificial species concepts subdivided by subspecies, varieties and forms, combined with minimal descriptions (Clauzade et al. 1981;Knudsen et al. 2014;Roux 2007). We are currently working on the revision of Acarosporaceae in central Europe to produce better illustrated keys for the region. ...
... Besides the above three species, three other species treated as either synonyms or varieties of Acarospora nitrophila were confused with A. nitrophila by Clauzade and Roux in their keys (Clauzade et al. 1981;Roux 2007). We are working on revisions of these species, but all three can be easily distinguished from the small, squamulose thalli of A. nitrophila with a simple observation. ...

Acarospora nitrophila is lectotypified and a new description is supplied with photographs. It is currently considered a rare saxicolous species only positively known from Norway and Sweden. A key is supplied for some European species commonly confused with A. nitrophila.
... This revision went unnoticed. Clauzade & Roux (1981) included the species in A. versicolor and at the Italian lichen website A. cinerascens is still considered a synonym of A. versicolor (Nimis & Martellos 2008). Only recently did Roux (2008) include it in his keys for European Acarospora taxa. ...
A. cinerascens is accepted as distinct from A. versicolor based on larger spores and areoles as well as apothecia with a higher hymenium. Acarospora cinerascens is lectotypified. Acarospora alboatra is accepted as a synonym of A. cinerascens.
... lat. range in colour from dull-grey, brown to yellow-green (Clauzade et al., 1981;Clauzade et al., 1982) (Figure 3). Although lichen colour is often due to the presence of lichen products of fungal origin (Huneck and Yoshimura, 1996;Elix and Stocker-Wörgötter, 2008), it has long been suspected that it may be affected by the chemical composition of the substrate itself (Hawksworth, 1973). ...
... lat. in different geological settings with reference to photographic quadrat monitoring carried out to monitor Acarospora sinopica over the period 1993-2013 at Parys Copper Mountain, south of Amlwch on Anglesey, North Wales. Crustose lichenized fungi in the Acarosporaceae include splendid examples of organisms tolerating extreme conditions, such as stressful pH conditions (Wirth, 1972), high nutrient concentrations around bird colonies (Clauzade et al., 1981;Øvstedal and Smith, 2001). Others tolerate both natural pollution e.g. ...
One of the most successful mechanisms enabling fungi to survive in extreme subaerial environments is by formation of mutualistic symbioses with algae and/or cyanobacteria as lichens. Collections, field and mineral weathering studies and developments in modern instrumental and analytical techniques have considerably advanced knowledge in understanding tolerance mechanisms to stress, environmental adaptation, species concepts and evolutionary processes in lichens colonising metalliferous habitats. This review focuses on the predominantly saxicolous, crustose, taxonomically notoriously challenging Acarospora sens. lat. Pioneering studies investigating element and substance localization in Acarospora sens. lat. in different geological terrains led to the discovery of novel fixation mechanisms, new minerals and substances associated with lichens, and new taxa and evolutionary lineages. Acarospora sens. lat. are generally under-represented in collections. Systematic sampling of Acarospora sens. lat. and other saxicolous lichens, in different mineralogical environments is now required, a priority being those occurring in extreme habitats at risk from climatic and other environmental changes. The potential for the discovery of new lichen and mineral species associated with Acarospora and other saxicolous crustose lichens, is high. These may represent special mechanisms to tolerate metal toxicity and other forms of environmental stress, including photoprotection.

... Acarospora charidema is a pioneer species described from south-east Spain that was later found in Morocco (EGEA & ROWE 1987), formed by robust, moderately convex squamules, up to 5(-6) mm wide; with numerous apothecia up to 0.5 mm wide (CLAUZADE & al. 1981). Acarospora charidema is usually distinguished from A. epi- thallina H. MAGN., a juvenile parasite of A. hilaris (DUFOUR) ARNOLD, on the basis of life habit, ecology and shape of spores, which are globose in A. epithallina and ovoid in A. charidema (CLAUZADE & al. 1981) but bears a possible resemblance to free- living squamules of A. epithallina (CRESPO & al. 1976). ...

... En effet, ce caractère est souvent inconstant et d'utilisation difficile chez les Acarospora et chez les lichens crustacés en général car son expression dépend du milieu, en particulier du substrat. Dans le groupe de A. smarag dula, Magnusson (1929 Magnusson ( , 1935) et Westberg et al. (2011) indiquent que les flancs et la face inférieure des squamules sont pâles, mais G. Clauzade † et C.

... En cohérence avec la diagnose originale de Smith (1918 : « thallus K+ yellow then red »), Westberg et al. (2011) ont lectotypifié A. lesdainii par un spécimen appartenant à A. smaragdula. En conséquence les spécimens à cortex dépourvu de microcristaux et d'acide norstictique et à couche algale inter rompue et fortement irrégulière (« en dentelle » selon Clauzade et Roux, 1982) sont à rapporter à T. hassei (voir plus haut et Leg.

A detailed and illustrated morphological and anatomical comparison between Polysporina subfuscescens and Trimmatothelopsis versipellis clearly shows that the latter species is not an unidentified lichen parasitized by Polysporina subfuscescens as suggested by Westberg et al. (2011). Instead, this species corresponds to an Acarospora gr. smaragdula, more specifically Acarospora rhagadhiza (syn. A. scyphulifera) as already noted by Roux and Navarro–Rosinés (2002). As a result, Silobia M. Westb. et Wedin (2011) is considered as a synonym of Trimmatothelopsis Zsch. (1934) and the following new combinations are proposed : Trimmatothelopsis dilatata (M. Westb. et Wedin) Cl. Roux et Nav.–Ros. comb. nov., Trimmatothelopsis hassei (Herre) Cl. Roux et Nav.–Ros. comb. nov., Trimmatothelopsis myochroa (M. Westb.) Cl.

The number of undescribed species of lichenized fungi has been estimated at roughly 10,000. Describing and cataloging these would take the existing number of taxonomists several decades; however, the support for taxonomy is in decline worldwide. In this paper we emphasize the dire need for taxonomic expertise in lichenology. We bring together 103 colleagues from institutions worldwide to describe a total of 100 new species of lichenized fungi, representing a wide taxonomic and geographic range. The newly described species are: Acarospora flavisparsa, A. janae, Aderkomyces thailandicus, Amandinea maritima, Ampliotrema cocosense, Anomomorpha lecanorina, A. tuberculata, Aspicilia mansourii, Bacidina sorediata, Badimia multiseptata, B. vezdana, Biatora epirotica, Buellia sulphurica, Bunodophoron pinnatum, Byssoloma spinulosum, Calopadia cinereopruinosa, C. editae, Caloplaca brownlieae, C. decipioides, C. digitaurea, C. magnussoniana, C. mereschkowskiana, C. yorkensis, Calvitimela uniseptata, Chapsa microspora, C. psoromica, C. rubropulveracea, C. thallotrema, Chiodecton pustuliferum, Cladonia mongkolsukii, Clypeopyrenis porinoides, Coccocarpia delicatula, Coenogonium flammeum, Cresponea ancistrosporelloides, Crocynia microphyllina, Dictyonema hernandezii, D. hirsutum, Diorygma microsporum, D. sticticum, Echinoplaca pernambucensis, E. schizidiifera, Eremithallus marusae, Everniastrum constictovexans, Fellhanera borbonica, Fibrillithecis sprucei, Fissurina astroisidiata, F. nigrolabiata, F. subcomparimuralis, Graphis caribica, G. cerradensis, G. itatiaiensis, G. marusa, Gyalideopsis chicaque, Gyrotrema papillatum, Harpidium gavilaniae, Hypogymnia amplexa, Hypotrachyna guatemalensis, H. indica, H. lueckingii, H. paracitrella, H. paraphyscioides, H. parasinuosa, Icmadophila eucalypti, Krogia microphylla, Lecanora mugambii, L. printzenii, L. xanthoplumosella, Lecidea lygommella, Lecidella greenii, Lempholemma corticola, Lepraria sekikaica, Lobariella sipmanii, Megalospora austropacifica, M. galapagoensis, Menegazzia endocrocea, Myriotrema endoflavescens, Ocellularia albobullata, O. vizcayensis, Ochrolechia insularis, Opegrapha viridipruinosa, Pannaria phyllidiata, Parmelia asiatica, Pertusaria conspersa, Phlyctis psoromica, Placopsis imshaugii, Platismatia wheeleri, Porina huainamdungensis, Ramalina hyrcana, R. stoffersii, Relicina colombiana, Rhizocarpon diploschistidina, Sticta venosa, Sagenidiopsis isidiata, Tapellaria albomarginata, Thelotrema fijiense, Tricharia nigriuncinata, Usnea galapagona, U. pallidocarpa, Verrucaria rhizicola, and Xanthomendoza rosmarieae.
