    The striking red pigments in the apothecia of species of Haematomma are concentrated mostly in the epihymenium above the tips of the asci. In this Haematomma persoonii the pigment is a tetracyclic anthraquinone called russulone. The compound has been found in the epihymenia of eight of Australia’s 13 known species of the genus. Haematomma persoonii colonizes bark in the woodlands and forests of eastern Queensland and New South Wales in Australia. Elsewhere in the world it occurs in all of the Americas, plus several sites in Africa and the Pacific. 1 mm CONTENTS ARTICLES Elix, JA; Mayrhofer, H; Rodriguez, JM—Two new species, a new combination and four new records of saxicolous buellioid lichens (Ascomycota, Caliciaceae) from southern South America ............................................................................................... 3 McCarthy, PM; Elix, JA—Sclerophyton puncticulatum sp. nov.

Nelsen, [email protected] Abstract: We present a revised phylogeny of lichenised Dothideomyceta (Arthoniomycetes and Dothideomycetes) based on a combined data set of nuclear large subunit (nuLSU) and mitochondrial small subunit (mtSSU) rDNA data. Dothideomyceta is supported as monophyletic with monophyletic classes Arthoniomycetes and Dothideomycetes; the latter, however, lacking support in this study. The phylogeny of lichenised Arthoniomycetes supports the current division into three families: Chrysothrichaceae (Chrysothrix), Arthoniaceae (Arthonia s. l., Cryptothecia, Herpothallon), and Roccellaceae (Chiodecton, Combea, Dendrographa, Dichosporidium, Enterographa, Erythrodecton, Lecanactis, Opegrapha, Roccella, Roccellographa, Schismatomma, Simonyella). The widespread and common Arthonia caesia is strongly supported as a (non-pigmented) member of Chrysothrix. Monoblastiaceae, Strigulaceae, and Trypetheliaceae are recovered as unrelated, monophyletic clades within Dothideomycetes. Also, the genera Arthopyrenia (Arthopyreniaceae) and Cystocoleus and Racodium (Capnodiales) are confirmed asDothideomycetes but unrelated to each other.

Lavallée 1, BE-1080 Bruxelles, Belgium *Author for correspondence: [email protected] Background and aims – The Arthoniaceae form a species-rich family of lichenized, lichenicolous and saprophytic fungi in the order Arthoniales. As part of taxonomic revisions of the African Arthoniaceae, a number of species assignable to the genus Synarthonia were collected and sequenced. The present study aims at placing the genus in a phylogeny for the first time and at clarifying its circumscription. Methods – Nuclear (RPB2) and mitochondrial (mtSSU) DNA sequences from freshly collected specimens were obtained and analysed with phylogenetic Bayesian and maximum likelihood (ML) methods. Key results – Synarthonia is closely related to the genera Reichlingia and Coniocarpon in the Arthoniaceae. Six Synarthonia species are described as new to science and ten new combinations into this genus are made. A worldwide identification key to the genus Synarthonia is provided. Lectotypes are chosen for Arthonia elegans, A.
