WAYNEA-ADSCENDENS RICO (LICHENES, LECANOR ALES, BACIDIACEAE) IN FRANCE

Waynea adscendens Rico, previously known in only four places in SE Spa in, exists also in SE France, but represented only by sterile specimen s. Theses are easily differentiated from W. stoechadiana (Abbassi Maaf et Roux) Roux et Clerc by their morphology (non geotropic squamules a nd forciniform or cupuliform soralia), anatomy (cortex distinctly pros oplectenchymatous, thicker medullary hyphae), chemistry (no lichen sub stance) and ecology (less thermophilous). They differ from W. californ ica Moberg by their clearly prosoplectenchymatous cortex and their thi cker medullary hyphae.
