Los Géneros Coccocarpia (Ascomycota: Peltigerales) Y Dictyonema En El Valle Del Cauca (Colombia)

In the Valle del Cauca, few studies have been devoted to the biology of lichens and the knowledge of the lichen diversity in the region is scarce. Lichens of the genera Coccocarpia and Dictyonema have been little studied and there are only very recent reports of four species (Coccocarpia erythroxyli, C. palmicola, Dictyonema glabratum, D. sericeum). In order to address the general lack of information regarding lichen diversity on a local scale, this study aimed at an inventory of the genera Coccocarpia and Dictyonema for the region. As a result, twelve new records for the Valle del Cauca are presented, two of which are also new records for Colombia. Ten species of Coccocarpia were found, seven of which are new records for the department (C. dissecta, C. domingensis, C. epiphylla, C. filiformis, C. pellita, C. prostrata and C. tenuissima) and one for Colombia (C. microphyllina). We found seven species of Dictyonema (D. glabratum, D. hernandezii, D. membranaceum, D. melvinii, D. phyllophilum, D. schenkianum, D. sericeum). We propose D. phyllophilum (Parmasto) Soto, Lucking & Bolanos as new combination. Dictyonema hernandezii is reported for Colombia for the first time, while D. membranaceum, D. melvinii, D. phyllophilum and D. sericeum f. schenckianum are new reports for Valle del Cauca.
