Pannaria conoplea and P. tavaresii (Ascomycota: Pannariaceae) new to Chile

Abstract

A collection of lichens made in 1998 (by WQ) from the bark of Austrocedrus chilensis at a locality in southern Chile, disclosed two species of Pannaria not hitherto recorded from the Chilean lichen mycobiota (Galloway & Quilhot 1999): (1) the pantemperate taxon Pannaria conoplea (Ach.) Bory, which is widespread in the Northern Hemisphere as well as having rare outliers in East Africa, Venezuela, Ecuador and Australia (see Jørgensen 1978; Swinscow & Krog 1988; Jørgensen & Galloway 1992; Jørgensen & Arvidsson 2004), and (2) Pannaria tavaresii P. M. Jørg., known earlier from North America (including Mexico and Jamaica), Portugal, Macaronesia (Jørgensen 1978), Australia (Jørgensen & Galloway 1992), Sardinia and Italy (Nimis 1993) and previously collected in 1986 from near Valdivia in Chile. The discovery of Pannaria conoplea and P. tavaresii in Chile adds to the known Pannaria mycobiota of Chile (Galloway & Quilhot 1999), bringing the total number of species of this genus in Chile to 23. Eleven taxa formerly placed in Psoroma, are now correctly accommodated in Pannaria (see Jørgensen 2001b; Elvebakk & Galloway 2003; Jørgensen & Sipman 2004; Passo et al. 2004). Both Pannaria conoplea and P. tavaresii are within the currently accepted circumscription of Pannaria (Jørgensen 1994, 2004a, 2004b). Descriptions of the Chilean material are given below.
