Licea rufocuprea Nann. -Bremek. & Y. Yamam., Proc. Kon. Ned. Akad. Wetensch., C. 90(3): 325 (1987) Figs. 18A–K Sporophores sporocarpic, scattered, sessile. Sporocarps subglosose to conical, up to 0.1 mm diam., red-coppery brown with a shiny circumcissile line near the base. Peridium double, the outer layer gelatinous, inner layer smooth with a minutely warted marginal area; dehiscence into irregularly sized lobes or platelets with a row of larger warts on the margins. Spores free, dark brown in mass, rosy brown by TL, globose, 9–11 µm diam., palely roughened. By SEM the inner peridium is minutely warted all over, with larger warts at the platelet margins; the epispore is densely covered with flat verrucae. FIGURE 17. Licea pygmaea .

Habitat: on the bark of living and dead trees Distribution: Japan , Singapore (?), La Réunion (?), Madagascar , USA , Puerto Rico , Brazil , Paraguay , Australia . Icon.: Nannenga-Bremekamp & Y. Yamamoto (1987: 325, Figs. 10A–D ), Yamamoto (1998: 134, Figs. A–B; 2021: 149, Figs. A–B), Wrigley de Basanta et al. (2013: 68, Figs. 31–36), Lima & Cavalcanti (2017: 284 , Fig. 4E ). Notes. The species is easily recognisable by its coppery, conical sporocarps with a basal circumcissile ring. The whole peridium sometimes dehisces along this ring (Wrigley de Basanta et al. 2013, Figs. 26–32), but then it breaks up into irregular smaller platelets ( Fig. 18H ). For this reason Nannenga-Bremekamp & Yamamoto (1987) assigned the species to the subgenus Licea . Although apparently quite rare, the species has a wide distribution, since it is known from Japan ( Nannenga-Bremekamp & Yamamoto 1987 ), Madagascar (Wrigley de Basanta et al. 2013), USA , Puerto Rico and Australia (GBIF), and Paraguay (as Licea sp. , see McHugh 2009 ). There are also unconfirmed reports from La Réunion ( Adamonyte et al. 2011 ) and Singapore (Rosing et al. 2011).
