Orientierende Untersuchungen zur Wirkung der Staubimprägnierung von Borken auf epiphytische Flechten
(2009)
Staubimprägnierung wird als wesentlicher Faktor für die Beeinflussung des Borkensubstrates von epiphytischen Flechten erachtet, da er das Nährstoffangebot und den pH-Wertes der Baumoberfläche beeinflusst. Es gibt jedoch bislang keine Untersuchungen und Daten über Art und Weise dieser Wirkung. Daher wurden im Stadtgebiet von Bonn die Leitfähigkeit (als Referenz für die Staubmenge) und der pH-Wert von Borken in verschiedenen verkehrsbeeinflussten Gebieten gemessen. Es zeigte sich, dass die Staubmenge verkehrsabhängig ist und der pH-Wert bei steigendem Staubeinfluss sinkt. Da der Staub bei Regenfällen jedoch immer wieder abgespült wird, wird der Staubeinfluss auf das Substrat insgesamt für gering erachtet. Hingegen wird der osmotische Effekt von löslichen Stäuben für wichtig gehalten.

The species, Bactrospora lamprospora (Nyl.) Lendemer is treated as a synonym of B. metabola (Nyl.) Egea & Torrente. The comparission of characters of all accessible materials and type specimens confirmed that B. lamprospora is conspecific with B. metabola. The distinguishing characters of B. metabola from other species in this group are initially a Homalotropa-type ascospores becomes muriform at maturity, with up to 24–30 transverse septa and ascospore size of 48–105 × 7–14 μm.

Eight new lichen species are described from South America, Malaysia and Thailand, viz. Chapsa canaimae from Venezuela, which differs from C. alborosella in having distictly smaller ascospores with less septa, Dirinaria hypoleuca from Thailand, which differs from the isidiate D. papillulifera in having a whitish lower surface, Myriotrema robertianum from Brazil, which differs from M. viride in having an inspersed hymenium, Myriotrema subzollingeri from Brazil, which differs from M. glauculum in having brown ascospores, Ocellularia jutaratiae from Brazil, which differs from O. crocea in having ascomata with a fissured margin, Ocellularia subnatashae from Brazil, which differs from O. natashae in lacking hirtifructic and conhirtifructic acids and in having smaller and less sepatate ascospores, Redingeria uniseptata from Brazil, which differs from R. vulcani in having smaller and 1-septate ascospores, Thalloloma intermedium from Brazil, which differs from T. anguiniforme in having smaller ascospores. Chapsa pulchella from Malaysia is a new record for Borneo and the first finding after its description, and Redonographa parvispora from Brasil is a new addition to the lichen biota of this country. All species mentioned are described and illustrated with close-up photographs.

New or otherwise interesting lichens. VII, including a world key to the lichen genus Heiomasia
(2020)
Eight species new to science are described, Allographa grandis from Cameroon which is distinguished by its very large ascomata, richly muriform, large ascospores and an inspersed hymenium (type B); Bapalmuia microspora from Malaysia which differs from B. consanguinea in having shorter and broader ascospores and a granular thallus; Diorygma cameroonense from Cameroon which differs from D. sticticum in having larger ascospores with more septa; Glyphis frischiana which is similar to G. atrofusca but differs in producing secondary lichen compounds, the first species in Glyphis in doing so. Two new species are added to the genus Heiomasia, viz. H. annamariae from Malaysia, which differs from H. sipmanii in producing the stictic acid aggr. and H. siamensis from Thailand, distinguished from H. sipmanii in containing hypoprotocetraric acid as a major metabolite. The published chemistry of several species of Heiomasia is revised and a new substance, heiomaseic acid, with relative Rf-values 5/19/8, is demonstrated for H. seaveyorum, H. siamensis and H. sipmanii. A world-wide key to the known species of Heiomasia is presented. Myriotrema squamiferum, a fertile species from Malaysia, is distinguished from M. frondosolucens by lacking lichexanthone. As there are conflicting literature data concerning Ocellularia crocea, the type specimen was investigated and the results are reported. Ocellularia macrocrocea, a related species from Malaysia, differs from O. rubropolydiscus in lacking the red pigment covering the disc of the ascomata and in having a broad stump-shaped columella. A revised chemistry for Ocellularia tanii, a new record for Sarawak, is also given. A table of Rfvalues and scans of relevant TLC runs facilitate the interpretation of the spots occurring on TLC plates of Graphidaceae.

Ten species of the lichen family Graphidaceae are treated in the ninth contribution to this series. Four species are new to science: Allographa cameroonensis Kalb & Schumm from Cameroon differs from A. grandis in having larger ascospores and in the lack of secondary lichen products. Allographa kuetchangiana Kalb & Schumm from Thailand differs from A. mexicana in having a permanent thalline cover of the ascomata and in having a whitish pruina on their top. Cruentotrema siamense Lücking & Kalb from Thailand differs from C. amazonum in having smaller ascomata and smaller ascospores. Ocellularia striata Kalb & Schumm from Thailand differs from O. jutaratiae in having smaller ascospores and in lacking the purplish, K+ greenish pigment which covers the remnants of the split proper exciple. Rhabdodiscus exutus (Hale) Kalb & Schumm is a new combination (Bas.: Ocellularia exuta Hale). Photographs of Allographa mexicana (Hale) Lücking & Kalb (including an isotype) show the variation of the ascomata and the differences to A. kuetchangiana. Allographa isidiata (Hale) Lücking & Kalb is reported from Ecuador, which is a new addition to the lichenobiota of this country and the second finding of this species after its description. Allographa plagiocarpa (Fée) Lücking & Kalb, before misidentified as A. mexicana, from Cartago Province is the second report of this species from Costa Rica. The chemistry of Ocellularia kohphanganensis Papong, Mangold & Lücking and the exact spelling of the specific epithet are corrected. Ocellularia macrocrocea Kalb is a new addition to the lichenobiota of Thailand where it is sometimes growing together with O. striata. The intraspecific variation of Ocellularia thelotremoides (Leight.) Hale ist discussed and the name is put on the correct place of the amended key to Thai Ocellularia species. Cochromatography of some Ocellularia species with a deep orange-yellow pigment together with a pure sample of skyrin in solvents A, B' and C showed identical Rf-values in all three solvent systems.

In a continuation of my investigation of tropical lichenized fungi, a treatment of new or otherwise interesting lichens mainly from Brazil and Venezuela is presented. A total of 34 species are reported here, most of them new discoveries for at least one the two countries or a new discovery for a state, including 11 species new to science. These are Malmidea albomarginata Kalb & Hernández from Venezuela, differing from M. granifera by the thin, white apothecial margins and a white to yellowish medulla, M. allobakeri Kalb & M. Cáceres from Brazil, differing from M. bakeri in lacking atranorin and in having smaller ascospores, M. allopapillosa Kalb from Venezuela, differing from M. papillosa in having atranorin as a major metabolite, M. atlanticoides Kalb & M. Cáceres from Brazil, differing from M. atlantica in containing atranorin and an unknown anthraquinone as major metabolites, M. hechicerae from Venezuela, differing from M. coralliformis by the K+ lemon-yellow medulla of the thallus, M. hernandeziana Kalb from Venezuela, differing from M. fellhaneroides in having a chocolate-brown hypothecium, larger apothecia and larger ascospores, M. isidiifera Kalb from Brazil and Venezuela, differing from M. piperis in having granular to coralloid isidia and atranorin as a major metabolite, M. leucopiperis Kalb from Brazil and Venezuela, differing from M. piperis in the pale-colored hypothecium, M. rhodopisoides Kalb from Brazil, differing from M. rhodopis in having granular isidia, M. subcinerea Kalb from Venezuela, differing from M. cinerea in producing no lichen substances, and M. volcaniana Kalb & Hernández from Venezuela and Brazil, differing from M. sulphureosorediata in having an alternative anthraquinone-chemistry. In addition, the new combination Stigmatochroma glaucothecum (Fée) Kalb is proposed. New reports for Venezuela include Bacidiopsora microphylla Kalb, B. silvicola (Malme) Kalb (new also for Guatemala), Buellia albula (Nyl.) Müll. Arg., Coenogonium pyrophthalmum (Mont.) Lücking, Aptroot & Sipman, Dirinaria rhodocladonica Kalb, Schumm & Elix, Malmidea badimioides (M. Cáceres & Lücking) M. Cáceres & Kalb (new also for Mexico), M. leptoloma (Müll. Arg.) Kalb & Lücking, M. nigromarginata (Malme) Lücking & Breuss, M. perplexa Kalb, M. polycampia (Tuck.) Kalb & Lücking, M. rhodopis (Tuck.) Kalb, Rivas Plata & Lumbsch, M. sulphureosorediata M. Cáceres, D. A. Mota & Aptroot, M. vinosa (Eschw.) Kalb, Rivas Plata & Lumbsch, Psilolechia lucida (Ach.) Choisy, Rhizocarpon sipmanianum Kalb & Aptroot, Sipmaniella sulfureofusca (Fée) Kalb, Stigmatochroma glaucothecum (Fée) Kalb and Vainionora aemulans (Vain.) Kalb. A collection of Pyxine caesiopruinosa (Nyl.) Imsh. from Venezuela is mentioned and its differentiation from P. albovirens (G. Mey.) Aptroot is discussed. New reports for Brazil include Malmidea atlantica (M. Cáceres & Lücking) M. Cáceres & Kalb (for Bahia state) and M. sulphureosorediata (for São Paulo state). A morphological, anatomical and chemical comparison of type material of Malmidea polycampia (Tuck.) Kalb & Lücking and M. flavopustulosa (M. Cáceres & Lücking) M. Cáceres & Kalb revealed that both names are synonym, the first one having priority. For many species revised descriptions and revised chemistry are presented based on South American material. To facilitate the identification of anthraquinones occurring in Malmidea species a table of relative Rfvalues in solvents A, B' and C is presented.

The Pantanal is a wetland biome in the interior of Brazil. It is known for its rich macrofauna. Botanically, it is relatively species poor, although the marshes have trees and shrubs throughout and there are occasional forested, even somewhat rocky hills. Lichens have received only scant attention so far, but the area is not very species rich (Canêz et al. 2020). We visited the Pantanal several times and collected in different areas. Here we describe four new species, one of which is locally the most common macrolichen, which was found on places elsewhere in the state and in the bordering state of Mato Grosso as well.

Eleven species of lichens are described as new from the Serra do Bodoquena in Mato Grosso do Sul (Brazil): Alyxoria cyanea, Astrothelium ochraceum, Chiodecton xanthonosorediatum, Gyalecta perithecioidea, Gyalecta uniseptata, Pyrenula rubroacutispora, Ramonia xylophila, Synarthonia xanthosarcographoides, Trypethelium aureornatum, Trypethelium endoflavum, and Trypethelium xanthostiolornatum. Around 400 further species are reported, of which 27 are first records for Brazil and 265 are first records for the state.
23
Six species of lichens are described as new from Santa Catarina and Rio Grande do Sul (Brazil): Astrothelium aureoirregulare Aptroot & Gumboski, Bogoriella xantholateralis Aptroot, Lecanora umbilicatimmersa Aptroot & Spielmann, Lepra lichexanthonorstictica Aptroot, Megalaria flavosorediata Aptroot and Vainionora sorediata Aptroot. Moreover, 28 further species are reported which are first records for Brazil; and a further 166 are first records for Santa Catarina and 104 for Rio Grande do Sul.

Based on recent records, 89 lichen species are reported as new to Brazil. For the genera Ancistrosporella, Jamesiella, Lambiella, Paulia, Polyblastia, Porocyphus, and Trimmatothele, it is the first time they are reported from Brazil. Many more, in total 523 species, are newly reported from individual states.
16
Nine species of Graphidaceae are described as new to science from South and Central Brazil, in 7 different genera: Acanthothecis normuralis, A. psoromica, Acanthotrema minus, Aggregatorygma submuriforme, Allographa medioinspersa, Diorygma isidiolichexanthonicum, Fissurina excavatisorediosa, Graphis norsorediata, and Graphis tricolor.
