FIGURE 1 in Eight new species of lichenized Basidiomycota in the genera Acantholichen, Cyphellostereum and Dictyonema s.str. (Agaricales, Hygrophoraceae) from northern South America

FIGURE 1. Details on the anatomy of Dictyonema s.lat. species from northern South America. Cyanobacterial cells (Rhizonema) involved in fungal sheath formed by jigsaw puzzle-shaped cells seen in Dictyonema andinum (scale A = 20 μm, B = 22 μm), D. laurae (scale C = 13 μm, D = 14 μm), D. umbricola (scale E = 14 μm, F = 15 μm), D. subsericeum (scale G = 30 μm). In Cyphellostereum mucuyense the cyanobacterial filaments are covered by thin elongated fungal cells, not forming jigsaw-puzzle-shaped cells (scale H = 15 μm). Photos by V. Marcano.
