Cora undulata L. Vargas, Moncada & Lücking

Cora undulata L. Vargas, Moncada & Lücking View in CoL , The Bryologist 117 (4): 374 (2014)

Description.

For the characteristic of the species, see Vargas et al. (2014).

Habitat and distribution.

Until now Cora undulata was only known from the type locality in Colombia growing on rocks and associated with bryophytes in more or less exposed microhabitats ( Vargas et al. 2014). The record of C. undulata given here is the first from Bolivia. Specimens were found at an elevation of 544 m in the Sub-Andean Yungas forest.

Specimens examined.

Bolivia • Dept. Cochabamba; Prov. Chapare, Parque Nacional Carrasco, Camino de las Nubes near Guacharos , 17°05'06"S, 65°29'12"W, elev. 544 m, Sub-Andean Yungas forest, July 2009, P. Rodriguez 3621 ( KRAM; LPB) GoogleMaps .

Notes.

The examined specimen of Cora undulata has foliose thallus smaller (up to 7.5 cm diam.) than specimens from Colombia (up to 9 cm diam.). Upper surface is dark olive-green when fresh, but when dried greyish white, with fine but distinct concentric ridges, glabrous. The species is morphologically close to C. ciferrii (Tomas.) Lücking, A. Grall & Thüs. It is characterised by an undulated surface and the hymenophore forming larger, more irregular patches that often become confluent ( Lücking et al. 2014 a). In comparison, C. undulata forms smaller lobes with dark olive-green colour when fresh and is saxicolous ( Vargas et al. 2014).
