INTRODUCTION On wooden fences and fence poles, there is often a lush veg- etation of lichens present, mostly a mosaic of crustose species The Serra de Maracaju is situated in Mato Grosso do Sul, at with the occasional foliose and fruticose species overgrowing the margin of the pre-cambrian sandstone plateau that cov- them. Most of the species present on this substratum are also ers most of the state. Here, steep cliffs, created by the Aqui- known from bark, but not all. dauana river and its tributaries, mark the transition to the Among the species that seem to be characteristic for wooden Pantanal. Exposed parts of the cliffs are covered by lichens, fences are two species of Lecanora Ach. that we found in vari- predominantly Xanthoparmelia (Vain.) Hale. Trees and shrubs ous places but that seem to be undescribed so far. Lecanora support additional species, and the wooden poles of fences is in the current wide sense a large genus, the type genus of posts are often full of lichens as well.

The genus Trypethelium Spreng. is common and turns out Cladonia P. Browne, the type genus of the Cladoniaceae to be quite rich in species in southern Brazil. It is the type Zenker, is a large genus of generally fruticose lichens. Most genus of the Trypetheliaceae Eschw., and was monographed by species are dimorphic, composed of a squamulose or crustose Aptroot & Lücking (2016). Recently (Aptroot & Spielmann basal part and a vertically elongated and usually branched part 2020), three new species were described from Mato Grosso called podetium. Observations of such crustose basal thalli are do Sul alone. Here we add another one, the first species in restricted to a small portion of the species assigned to subgenus this genus with muriform ascospores. Cladina Nyl., as most species occur on soil and such crusts are only developed on the rare cases when such species grow in a more stable substratum like decorticated wood. Brazil is the MATERIAL AND METHODS country with the world’s richest Cladonia funga, in species number, number of endemic species and spread in characters During three trips in 2019 and 2020, specimens were collected by (Ahti 2000; Gumboski & Eliasaro 2011; Gumboski et al. the authors, using Opinel knife or hammer and chisel, examined 2013).
