TL;DR: The following four new corticolous Lecanorales are described from Rondônia: Calopadia granulosa with a granular, corticate thallus and ascospores 1 per ascus, 33–38×10·5–13·0 µm; Crustospathula amazonica with irregularly capitate to nearly globose, 0·2–0·4 mm diam.
Abstract: A key is given to the foliose and squamulose lichens known so far from Rondonia, including also corticolous crustose lichens with a chlorococcoid alga. The foliicolous Lecanorales found are also listed. The following four new corticolous Lecanorales are described from Rondonia: Calopadia gran- ulosa with a granular, corticate thallus and ascospores 1 per ascus, 33-38 � 10� 5-13� 0 mm; Crustospa- thula amazonica with irregularly capitate to nearly globose, c. 0� 2-0� 4 mm diam. soralia on cartilagi- nous stalks; Flavoparmelia plicata with a thallus containing usnic and protocetraric acids, with laminal, irregular, globose to cylindrical isidia which are often easily abraded and showing the whitish medulla, but not sorediate or postulate; Physcidia striata with ascending squamules, without hypo- thallus, often with laminal isidia in defined areas towards lobe tips of some, usually sterile lobes, and often with biatorine apothecia with ascospores simple to 1-septate, (6� 2-)7� 5-10� 0 � (2� 5-)3� 0-3� 5 mm. In the whole lichen flora of the lowland rainforest region of Rondonia, the following traits can be discerned: foliose lichens amount to only 17 species (2� 7% of nearly 600), 33 (5� 5%) are squamulose, while the vast majority (91� 8%) are crustose. Cyanobacteria are present in only 6 (1%) species. A chlorococcoid alga present in c. 100 (16%), 12 of which (2%) have a myrmecioid alga. The re- mainder of the species, a staggering 83%, have trentepohlioid alga, including 6 (1%) with Phycopeltis. In neotropical lowland rainforest, the vast majority of the lichens are crustose and contain a trente- pohlioid alga, and the Arthoniales, Graphidaceae and pyrenocarpous lichens are the main groups, each accounting for roughly a quarter of the lichen biodiversity.

TL;DR: Here 13species of the nonfoliicolous species of the lichen family EctolechiaceaeZahlbr.Haf.
Abstract: Here 13 species of the nonfoliicolous species of the lichen familyEctolechiaceae
Zahlbr. em.Haf. are reported, which were found in a collection from Brazil. Six species are described as new:Badimia corticola (sp.n.),Calopadia isidiosa (sp.n.),C. psoromoides (sp.n.),C. subfusca (sp.n.),Tapellaria corticola (sp.n.), andT. schindleri (sp.n.). Seven species have been identified with earlier described species:Calopadia chacoensis (Malme) comb. n. (=Lopadium chacoense
Malme),C. foliicola
(Fee) Vězda,C. fusca
(Mull. Arg.) Vězda,C. lecanorella (Nyl.) comb. n.,C. perpallida
(Nyl.) Věda,C. phyllogena
(Mull. Arg.) Vězda, andTapellaria epiphylla
(Mull. Arg.) Sant. A key and illustrations for all studied species are provided, and the nomenclatural problem of the correct generic name of thePyrenotrichum
Mont. (anamorph) forCalopadia
Vězda orTapellaria Sant. (teleomorphs) are discussed.

TL;DR: Two new species belonging to the lichen families Pilocarpaceae and Ectolechiaceae are described from tropical Africa, differing from the related F.rhapidophylli by the sorediate thallus and from other sorediates taxa by the combination of pale soralia, dark brown apothecia, and the ellipsoid-bacillar conidia.
Abstract: :
Two new species belonging to the lichen families Pilocarpaceae andEctolechiaceae are described from tropical Africa: Calopadia lucida sp. nov. (Ectolechiaceae) from Tanzania, being similar to C. puiggarii but differing in the UV fluorescent thallus and the pruinose apothecia, andFellhanera ivoriensis sp. nov. (Pilocarpaceae) from the Ivory Coast, differing from the related F. rhapidophylli by the sorediate thallus and from other sorediate taxa by the combination of pale soralia, dark brown apothecia, and the ellipsoid-bacillar conidia. A key to the nine sorediate species of Fellhanera is provided.

TL;DR: A revision of the lichen genus Gomphillus Nyl reveals that G. caribaeus W. R. Buck does not belong in that genus, but is a member of the Pilocarpaceae in the Lecanorales, and the new genus Bryogomphus is established for it.
Abstract: A revision of the lichen genus Gomphillus Nyl. in the Americas reveals that G. caribaeus W. R. Buck does not belong in that genus, but is a member of the Pilocarpaceae in the Lecanorales. Because of its distinctive features, the species cannot be accommodated in any of the known genera of that family, and the new genus Bryogomphus Lucking, W. R. Buck, Serus. & L. I. Ferraro is established for it. Bryogomphus is characterized by turbinate, vertically elongate, obconical apothecia with a disc-shaped top, anastomosing paraphyses forming a reticulum around individual asci, amyloid asci of the Sporopodium-type, and filiform, multiseptate ascospores. Most similar within the Pilocarpaceae is Bapalmuia marginalis, but that species differs in having unbranched, strongly coherent paraphyses and Byssoloma-type asci with a darker tubular structure in the tholus. Calopadia turbinata (Tuck.) Serus. & Lucking comb. nov. is also related but has a paraplectenchymatous excipulum, largely unbranched paraphyses, and oblong-ellipsoid, muriform ascospores. Bryogomphus shows a remarkable convergence with Gomphillus in the Gomphillaceae (Ostropales), being extremely similar even in many details, except for the amyloid asci, slightly thicker and irregularly bent paraphyses, externally thinly byssoid excipulum with labyrinthical structure, and disc-shaped top of the apothecia.

TL;DR: In this article, a new species of Lasioloma antillarum has been identified, which is characterized by a corticolous growth habit, apothecia with shortly tomentose margins, and rather small (35-50 × 12-16 µm), muriform ascospores in numbers of 2(−4) per ascus.
Abstract: We describe the new lichenized fungus Lasioloma antillarum Lucking, Hognabba & Sipman from the Netherlands Antilles. The new species is characterized by a corticolous growth habit, apothecia with shortly tomentose margins, and rather small (35–50 × 12–16 µm), muriform ascospores in numbers of 2(–4) per ascus. The material had originally been identified as Calopadia phyllogena (Mull. Arg.) Vězda, with associated sequence data, but in phylogenetic analyses consistently fell outside the latter genus. Its revised identification as a species of Lasioloma is consistent with its phylogenetic position and underlines the necessity of posterior annotations in public sequence repositories, in order to correct previous identifications.

M. 2021: Lasioloma antillarum (Ascomycota: Pilocarpaceae), a new lichenized fungus from the Antilles, and the importance of posterior annotations of sequence data in public repositories. – Willdenowia 51: 83–89.
