Abstract A novel species in the genus Squamulea, S. chikarensis, is described from Himalayan moist temperate forest in Pakistan. The morphology, chemistry and ITS sequences support its distinction from other species of this genus. The taxon is characterized by a pale green to yellow thallus, large apothecia up to 0.8–1.8 mm wide, pale yellow to yellow-orange apothecial discs, a hymenium 70–110 μm high, large ascospores (12–20 × 5–11 μm) and a narrow ascospore septum (1.5–3 μm). In addition, S. flakusii is reported as new to Pakistan and Eurasia.

Lichenized fungi are a major component of coastal marine ecosystems. Their distributions transition through a range of distinct environmental pressures that span from daily immersion in sea water to fully terrestrial ecosystems, sometimes within the space of only a few metres (Hawksworth 2000). Natural environmental gradients such as these are important for investigating ecological and evolutionary mechanisms due to their ability to drive shifts in species assemblage, niche differentiation, and local adaptation

Abstract Hair lichens are distinctive for their capillary growth and typically arboreal occurrence, especially in temperate and boreal forests. They consist of two morphogroups based on cortical pigments: a brown-black group with fungal melanin and a pale yellow-green group with usnic acid. Here we test the hypothesis that these morphogroups are ecologically distinct and thus appropriately regarded as functional groups. We examine their respective horizontal occurrence in the lower canopy of 60-year-old conifer forests on a 250 m tall volcanic cone in south-central British Columbia. Trees on open south-facing slopes and near the summit were found to support mainly melanic hair lichens (Bryoria and Nodobryoria), whereas more densely spaced trees on north-facing slopes and at the base had higher cover values of usnic lichens (especially Alectoria sarmentosa and Ramalina thrausta). The cover of melanic hair lichens was strongly correlated with canopy openness but not for their usnic counterparts. We suggest that investment in light-absorbing melanic pigments is an extreme form of specialization for high light, favouring persistence in dry, sun-exposed canopies of otherwise cool forests. By contrast, the cortex of pendent usnic hair lichens appears to facilitate optimum light transmission to underlying photobionts in shaded sites, though at the cost of sensitivity to light in open habitats, especially in rather dry regions.

Abstract Three new species of Arthoniales are described from Cape Verde: Ingaderia dendritica, with ascomata formed of richly branched-dendroid lirellae and containing erythrin; Sparria caboverdensis, with small stroma-like ascomata and ascospores with 3–7 transverse septa; and Syncesia miesii, with an I− thallus, a tomentose hymenial disc, and a chemistry with fatty acids only. Phylogenetic analyses using nuLSU and RPB2 sequences reveal the placement of Fulvophyton sorediatum, Llimonaea occulta, L. sorediata and Sparria caboverdensis in the family Opegraphaceae. The genus Llimonaea is recovered as paraphyletic, with L. flexuosa being placed as sister species to a lineage including the genera Ingaderia and Paraingaderia. In consequence, an enlarged concept of the genus Ingaderia is proposed, resulting in the transfer of F. sorediatum, L. flexuosa, L. occulta, L. sorediata and Paraingaderia placodioidea to Ingaderia.

Abstract Two new species of the lichenized genus Lasioloma are described from Asia: Lasioloma longiramosum W. C. Wang & A. Abas (collected from Malaysia), is characterized by a distinct woolly prothallus between dispersed thallus patches, comparatively small, muriform ascospores, long filiform conidia (main branch 22–28 μm in length, the other three branches 65–80 μm) and a foliicolous habitat; L. verrucosum W. C. Wang & X. L. Wei (collected from China), is characterized by a warted thallus, filiform conidia (main branch 22–32 μm in length, the other three branches 50–65 μm) and a corticolous habitat. The placement of both new species was confirmed by a molecular phylogenetic approach based on combined ITS, mtSSU and mtLSU sequences, and both are compared in detail to other similar species of the genus. Our study also revealed that the length of the conidial branches, which has not been explored in previous studies, should be regarded as an important feature for species delimitation in Lasioloma.

Abstract Clypeococcum wedinii, a pyrenocarpous ascomycete growing on the lichen genus Bunodophoron in Chile and New Zealand, is described as new to science. It differs from other Clypeococcum species in the combination of the following characteristics: a conspicuous gall formation, scattered, loose to dense stromatic growths sometimes looking like a clypeus, an ascomatal wall composed of both textura intricata and angularis in surface view, a non-amyloid hymenium, an absence of ostiolar filaments, 8-spored asci, and 1-septate ascospores arranged biseriately in the ascus. An updated key to the species of the lichenicolous genus Clypeococcum is provided.
