FIGURE 1 in Enterographa confusa sp. nov. (Roccellaceae, Arthoniales) discovered by chance in type material of its host lichen Arthonia ochraceella, described more than a century ago
FIGURE 1. Enterographa confusa (A–E, holotype, G). A. E. confusa (black arrows point to ascomata of the lichenicolous fungi) forming a paler, whitish area in the thallus of its host, Arthonia ochraceella (white arrows point to ascomata of the host lichen). B. Ascomata of E. confusa. C. Asci in water. D. asci in KI showing the KI+ blue apical ring. E. Ascospores in water. Scale in A = 500 μm, in B = 100 μm, in C–D = 10 μm, in E = 5 μm. (Photos D. Ertz).

FIGURE 1. Ancistrosporella. a–b A. leucophila. c–f A. onchospora. a Lectotype of A. leucophila. b Thallus and ascomata (lectotype of A. leucophila). c Lectotype of A. onchospora. d Thallus, prothallus and ascomata (lectotype of A. onchospora). e Ascus (isolectotype of A. onchospora). f Ascospore having one typical hooked end (isolectotype of A. onchospora). Scale bars: b, d=500 μm, e=15 μm, f=5 μm. (Photos D. Ertz)
FIGURE 2. A in New species and new records in Roccellaceae (Arthoniales) from the Andaman Islands, India
FIGURE 2. A. Bactrospora littoralis (holotype), V.S. of ascoma. B. B. medians (holotype), V.S. of ascoma. C–D. Sagenidiopsis atroalba (holotype), V.S. of ascoma in K. E–F. Bactrospora littoralis (holotype). E. Ascus in IKI. F. Ascospores. G–H. B. medians (holotype). G. Asci in IKI. H. Ascospores. I. Chiodecton andamanicum (holotype), ascospores. J. Sagenidiopsis atroalba (holotype), ascospores. Scales: A–D=50 µm, E–J=10 µm.
FIGURE 2 in Enterographa ducouretiana sp. nov. (lichenized Ascomycota, Roccellaceae), a new foliicolous species from New Caledonia
FIGURE 2. Enterographa ducouretiana sp. nov. (three months old herbarium specimen). A, B & E. Cross-sections of ascomata showing the purple tinge of the hypothecium and the thallus layer covering the surface of the pseudostromata (in water). C. Cross-section of an ascoma in K (note the color of the hypothecium that became black and the dissolution of the crystals in the margin that became more transparent). F. Thallus with trentepohlioid photobiont in irregular plates (in water). D. Ascus with spores (in water). G. Ascospores (in water). Scales: A–C, E–F = 20 μm, D & G = 5 μm.
