The "nested graft" is an innovative and well-defined surgical technique used for chronic wound healing that induces the de-senescence of fibroblasts in the wound bed. We report a case of a 76-year-old man affected by plantar chronic wounds because of acral lichen sclerosus and atrophicus localized at both feet and treated for many years successfully with immunosuppressive agents. For cardiologi...

Lichen nitidus (LN) is a rare chronic inflammatory disease of unknown etiology. It predominantly affects children and young adults. Its clinical manifestation typically corresponds to erythematous or flesh-colored, asymptomatic or little pruritic mini papules, often located in the trunk, genitalia, and extremities. The linear arrangement of this dermatosis seems rare. To our knowledge, only 2 c...

Four interesting lichens belonging to Catapyrenium, Placidium and Placopyrenium genera (Verrucariaceae) were collected for the first time in Argentina. Catapyrenium exaratum was only reported from Chile and Perú. Placidium acarosporoides was previously known from North America, Chile and South Africa. Placidium pilosellum, a widespread and common species, but little known in South America. Fina...

The loss of biological soil crusts represents a challenge for the restoration of disturbed environments, specifically in particular substrates hosting unique lichen communities. However, the recovery of lichen species affected by mining is rarely addressed in restoration projects. Here, we evaluate the translocation of Diploschistes diacapsis, a representative species of gypsum lichen communiti...

Leptogium (Ach.) Gray is distributed throughout South Korea; however, for nearly two decades no detailed taxonomic or revisionary research on this lichen genus has been conducted. This study examined the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and samples were identified using descriptions recently published in the scientific literature. In this revi...

The phylogenetic relationships of 16 species of Parmelia s. str. are presented based on sequences of nuITS rDNA from 56 specimens, and -tubulin gene sequences from 29 collections. Parmelia serrana sp. nov. a Mediterranean species morphologically very close to P. saxatilis is described. Parmelia ernstiae is the sister-group to P. saxatilis s. str., and a further undescribed North American specie...

Spanish holm oak (Quercus ilex subsp. ballota) open woodlands (dehesas) maintain a high diversity of plants and animals compared to other forested Mediterranean habits, but little is known about the responses of epiphytic lichens to different management regimes that are applied to this woodland type. The present study was carried out in central-southern Spain and included four management regime...

The Mars Desert Research Station is a Mars analog research site located in the desert outside of Hanksville, Utah, U.S.A. Here we present a preliminary checklist of the vascular plant and lichen flora for the station, based on collections made primarily during a two-week simulated Mars mission in November, 2014. Additionally, we present notes on the endolithic chlorophytes and cyanobacteria, an...

Ultrasonic mating signals in moths are argued to have evolved via exploitation of the receivers' sensory bias towards bat echolocation calls. We have demonstrated that female moths of the Asian corn borer are unable to distinguish between the male courtship song and bat calls. Females react to both the male song and bat calls by "freezing", which males take advantage of in mating (deceptive cou...

Lichen planus (LP) of the eyelid is an under-reportedmanifestation of a common inflammatory condition.To the best of our knowledge fewer than 20 cases ofeyelid LP have been described in the English literature.We report a case of a 29-year-old woman whopresented with 3-month history of bilateral eyelidpruritic violaceous papules and similar lesions on herchest and lower extremity. Histology exam...
