Dodge (1933: 419) . ( Figure 1A ) ≡ Leptogium cyanescens var. austroamericanum Malme (1924: 21) . Lectotype (designated in Benatti et al. 2013 ):— BRAZIL . Rio Grande do Sul : Santo Ângelo prope Cachoeira [Agudo municipality], 3 September 1819 , G . O . A . Malme 950 B ( S !); isolectotypes :— Malme 950 A e D ( S !). Description: Benatti et al. (2013) . Notes: Leptogium austroamericanum is an isidiate species with wrinkled upper surface. It has wide distribution ( Hua-Jie et al. 2012 ) but may be more restricted than previously thought. Similar species may have been identified as L. austroamericanum and for this reason a detailed review with specimens from different regions is necessary, along with molecular studies to delimit the real circumscription of the species. Distribution in Brazil : First record to Mato Grosso do Sul state , but previously recorded in Alagoas ( Pereira et al. 2006 ), Bahia ( Marcelli 1992 ), Mato Grosso ( Brako et al. 1985 ), Minas Gerais ( Aptroot 2002 ), Pará ( Brako et al. 1985 ), Rio de Janeiro ( Vainio 1890 ; Marcelli 1992 ), Rio Grande do Sul ( Spielmann 2006 ), Santa Catarina ( Gumboski & Eliasaro 2011 ), and São Paulo ( Benatti et al. 2013 ).
