Formal Instatement of Allographa (Graphidaceae): How to Deal with a Hyperdiverse Genus Complex with Cryptic Differentiation and Paucity of Molecular Data

Lichens from the Colombian Amazon: 666 Taxa Including 28 new Species and 157 New Country Records Document an Extraordinary Diversity

“…Allographa sitiana (Vain.) Lücking & Kalb agrees with the new species in morphology and anatomy and in the small, (3–)5-septate ascospores, but lacks secondary substances (Lücking et al 2009; Lücking & Kalb 2018).…”

“…Based on the prominent lirellae with heavily carbonized excipulum, the general appearance resembling the Allographa nuda (H.Magn.) Lücking & Kalb morph, and the inspersion rapidly dissolving in K, this new taxon is placed in the recently reinstated genus Allographa (Lücking & Kalb 2018). Given the striate labia, the completely carbonized excipulum, the inspersed hymenium, and the muriform ascospores, the species would key out in group 20 in Lücking et al (2009) and group 21 in Kalb et al (2018).…”

“…The partially carbonized excipulum in Allographa labiata is reminiscent of a few other species now placed in Allographa , namely A. gregmuelleri (Sipman & Lücking) Lücking & Kalb, A. immersa (Müll.Arg.) Lücking & Kalb, and A. mirabilis (Lücking, Sipman, Umana ̴ & Chaves) Lücking & Kalb (Lücking & Kalb 2018). All three have lirellae with an apically thin complete thalline margin (labia not exposed), finely striate labia, a clear hymenium and also differ in morphology, ascospore type, and lack of secondary substances (Lücking et al 2009).…”

“…Lücking & Kalb, which differs in the transversely septate ascospores and the more densely striate labia. Among species with striate labia, completely carbonized excipulum, clear hymenium, and muriform ascospores, all have ascomata with distinct lateral to complete thalline margin (Lücking et al 2009; Lücking & Kalb 2018).…”

“…Arg.) Lücking (Lücking y Kalb, 2018). En un sentido ecológico, los representantes de este género habitan ecosistemas tropicales y subtropicales, algunos como Glyphis cicatricosa son conocidos de todo el globo mientras que otros como Glyphis dictyospora Staiger solo han sido registrados en sus localidades tipo (Staiger, 2002).…”
