Three new species, new combinations and a key to known species of<i>Lobothallia</i>(<i>Megasporaceae</i>)

A new species in the genus Lobothallia (Megasporaceae, lichenized ascomycetes), from Margalla Hills, Pakistan, is described and illustrated here under the name Lobothallia densipruinosa. It is characterized by contiguous, clustered, densely pruinose dark olive apothecia, conidia 6-10 µm long, and large areoles and lobes. Phylogenetic analysis based on ITS-nrDNA sequencing placed our species relative to L. pruinosa. Descriptions and images of the new species are provided, as well as a key for the 21 species of Lobothallia known to the world.

Records of new and overlooked lichens from the Saïda province (Western Algeria). – Herzogia 36: 72–83.Eighty five lichens are reported for the first time from Doui-Thabet forest, Saïda province, Algeria, four of them (Acarospora aeginaica, Acarospora calcivora, Acarospora pitardii, Acarospora xanthophana) are new to Algeria. Of them Acarospora aeginaica is reported for the first time to north Africa. Ten of the recorded species are protected under the Algerian endangered species legislation. For all newly recorded species descriptions of morphology, anatomy, ecology and distribution are provided.

This work summarizes the results of the exploration of freshwater lichen biota on the island of Sardinia associated with the regional flagship species Lobothallia hydrocharis, a large-sized crustose lichen from the splash zone along mountain streams, so far known from Sardinia only. Molecular data were used to confirm its distinctiveness from other taxa and its systematic placement and to identify critical taxa among its associated lichen biota. We found 25 species of lichenized fungi, including three species new to science in the genera Verrucaria, Placopyrenium, and Circinaria, and seven species new to Sardinia (Hydropunctaria rheithrophila, Ionaspis chrysophana, I. odora, Verrucaria aquatilis, V. collematodes, V. pseudovirescens), or new to Southern Europe (V. devensis). Specific traits for the freshwater lichen biota of Sardinia were identified and compared to those reported from freshwater sites in the Alps and Carpathian mountains, e.g., a relative scarcity of subgelatinous lichens. Parasitic or epilichenic interactions were found frequently but only in the splash zone and not in the permanently submerged zone, i.e., two parasitic Placopyrenium species, and clearly lichenicolous thalli of Kuettlingeria atroflava and Lobothallia hydrocharis. Due to its specific trait profile and the great potential for the discovery of new species, we recommend the inclusion of Sardinian and further Mediterranean sites in continental-scale monitoring programs for freshwater lichens.
