Abstract:

AbstractAs part of a revision of the genus Acanthothecis s. lat. (Graphidaceae) in Brazil, an updated world key to the known species of the genus is presented. From Brazil, the following ten new species are described: A. latispora, with single-spored asci, large, muriform ascospores, and norstictic and stictic acids; A. megalospora, with single-spored asci, very large, transversely septate ascospores, and norstictic and protocetraric acids; A. multiseptata, with 8-spored asci, medium-sized and narrow, transversely multiseptate ascospores, and lacking secondary substances except terpenoids; A.

Abstract:

AbstractMost lichen-forming fungi are characterized by the production of secondary metabolites. Differences in metabolite patterns have frequently served to distinguish lichen taxa with subsequent controversies about the rank of chemical variants (chemotype, variety, subspecies or species). Using a model system, we investigate whether production of norstictic acid within a group of lichenized ascomycetes is correlated with phylogenetic patterns, population differentiation or single and multi-locus haplotypes. Our study is based on DNA sequences of three gene loci (ITS, GPD, mtLSU) together wit

Abstract:

In the floristic revision on the lichens of the Andaman and Nicobar Islands three more species in the family Roccellaceae are described as new to science: Chiodecton norsticticum sp. nov., Enterographa nicobarica sp. nov. and Gyrographa nigrofusca sp. nov. Chiodecton norsticticum has 7-septate small ascospores and norstictic acid. Enterographa nicobarica has simple to branched lirelliform ascomata in pseudostromata, 5–7-septate ascospores and lacking lichen substances. Gyrographa nigrofusca has simple to substellate lirelliform ascomata, 7-septate ascospores and lacking lichen substances Chiod

Abstract:A taxonomic investigation of Lethariella smithii and L. zahlbruckneri has established that they are conspecific. Three chemical races are recognized: race 1 containing norstictic acid, race 2 norstictic acid and placodiolic acid, and race 3 placodiolic acid as major medullary substances.

Abstract:

AbstractThe localization of norstictic acid and copper in green, copper-rich specimens of Acarospora smaragdula and Lecidea lactea from cupriferous substrata was studied by optical microscopy, scanning electron microscopy, and electron probe microanalysis. Infrared absorption spectroscopy of lichen material and a synthetic Cu-norstictic acid complex, and the other studies, provide evidence that complexing of copper by norstictic acid occurs within the cortex of these lichens and leads to their unusual surface coloration. Preliminary observations suggest that copper may also form a complex with

Abstract:

AbstractHerpothallon biacidum Frisch et al. is described from Queensland, tropical Australia. The new species is characterized by a thick byssoid thallus that is loosely attached to the substratum, globular to claviform to short cylindrical pseudoisidia, a brown to brownish black hypothallus, and by the presence of gyrophoric and norstictic acids. This is the first reported co-occurrence of gyrophoric and norstictic acids in the genus. The differences between H. biacidum and other species containing either norstictic acid or gyrophoric acid are discussed. Herpothallon biacidum is also compared

Abstract:

Cryptothecia aleurodes was considered to be a widespread, rare tropical lichen having white ascigerous areas and a crustose whitish-grey thallus containing norstictic acid. A revision of its type specimen from Guadeloupe and the study of recent specimens from Martinique proved that the species has been misunderstood. In this paper, Cryptothecia aleurodes is shown to have a K– and C+ red thallus containing notably gyrophoric acid as major secondary metabolite but lacking norstictic acid. A detailed description and illustrations are provided. The species is known with certainty only from the Car
