FIGURE 16 in Lecanoroid lichens in the Galapagos Islands: the genera Lecanora, Protoparmeliopsis, and Vainionora (Lecanoraceae, Lecanoromycetes)

FIGURE 16. Species in the L. varia-group. A–G. Lecanora confusoides. A–B. Thallus variation on different substrates. A. Thick, rimoseareolate thallus with ±adnate apothecia, disc brown, in parts with a dark grayish tinge, distinctly pruinose, on fibrous bark of Cordia (Bungartz, F. 8833, CDS 45651–holotype). B. Thin, endosubstratal to rimose, abundantly blastidiate-sorediate thallus with ±immersed apothecia, the apothecial margin blastidiate-sorediate (Bungartz, F. 7207, CDS 37691). C. Filiform conidia (Bungartz, F. 8833, CDS 45651). D. Asci with narrowly oblong ascospores (Bungartz, F. 8833, CDS 45651). E–G. Apothecial sections (in water, DIC). E. Proper exciple well developed, abundantly inspersed with small, orange granules, thalline exciple below reduced (Bungartz, F. 6044, CDS 33723). F. Proper exciple well developed, sparsely interspersed with small, orange granules, thalline exciple below moderately developed (Bungartz, F. 8833, CDS 45651). G. Proper exciple well developed, sparsely interspersed with small, orange granules, thalline exciple along the outside well developed, but ±disintegrating (Bungartz, F. 8833, CDS 45651). Scales: A & B = 5 mm; C = 20 µm; D = 10 µm; E, F & G = 100 µm.
