FIGURE 1 in Evaluation of diagnostic chemical and morphological characters in five Parmelia species (Parmeliaceae, lichenized Ascomycota) with special emphasis on the thallus pruinosity

FIGURE 1. Morphology of Parmelia species showing different categories of pruina intensity. A, epruinose thallus (category 0) of P. saxatilis (Ossowska 175, UGDA L-25124); B, partially pruinose thallus (category 1) of P. ernstiae (Kukwa 10867, UGDA L-24540; arrows show patches of pruina); C, pruinose thallus (category 2) of P. serrana with almost entire lobe with pruina (Ossowska s.n., UGDA L-21228); D, strongly pruinose thallus (category 3) of P. sulcata (Kukwa LV12960, UGDA L-19860; arrows show epruinose fragments of lobes). Scale bars = 1 mm.
