New data on Sculptolumina japonica (Physciaceae)

Sculptolumina japonica (Tuck.) Marbach, a species growing on lignum, bark or decaying plants and hitherto known from subtropical and tropical areas and one locality in North America, is now reported from Europe (northern Portugal) and the Canary Islands (La Gomera). This species has been found to possess filiform conidia. As a consequence we propose to amend the genus Sculptolumina to accommodate species that have long filiform conidia in addition to hymenial oil droplets and ascospores with internal wall thickenings. New chemical data are reported for S. japonica, the world distribution of this species is mapped and illustrations of the ascospores and conidia are provided

A first approach to the lichen flora of Guinea-Bissau

Twenty lichen taxa are reported as new from Guinea-Bissau; one is new to continental Africa, seven are reported for the first time from western Africa and one is described here as new to science, namely Pertusaria guineabissauensis, which has eight hyaline, smooth-walled ascospore per ascus and contains stictic acid
