(A) Optical microscopy observation and schematic representation of the cross section highlighting Rivularia-rich laminations with encrusted Rivularia-like cells. The localization of areas of interest analyzed by S-DUV fluorescence imaging is given. (B) Composite RGB images of 4 areas of interest were reconstructed using the fluorescence signal collected with filters between 327 and 353 nm (Blue), 370 and 410 nm (Green) and 420 and 480 nm (Red). They were surimposed on the optical image. An intense fluorescence signal was observed using the blue filter between 327 and 353 nm (black arrows) in Rivularia-rich laminations (underlined by dot lines in B,C) while the rest of the matrix is marked by a mixed fluorescence collected using the green and red filters. (C) The fluorescence emission signal associated with Rivularia-rich laminations was recorded and showed two bands at 316 and 341 cm−1. The fluorescence ranges covered by the three filters are indicated with respective colors and the precise localization where the spectrum was collected is given by a black star on the associated full-field RGB fluorescence image.
