AbstractThe taxonomy of the foliicolous members of Arthoniaceae (Anhonia, Arthothelium, Cryptothecia, Eremothecella) in Costa Rica is revised. Cryptothecia farkasiae sp. nov. is described, being closely related to Stirtonia sprucei, and bearing pycnidia reminiscent of Eremothecella. Anhonia lividofusca is placed in synonymy with A. aciniformis. Pycnidia and pycnospores are further described for Anhonialeptosperma, A. cyanea, A. palmulacea, A. trilocularis, Anhothelium cingulatum, Stinonia sprucei and S. macrocephala, and campylidia were found on thalli of Anhonia aciniformis. Anhonia nigratula and Cryptothecia Candida are reported for the first time from Costa Rica, and new localities are given for previously reported species. Ecological data are provided, and the relationships between foliicolous members of the Arthoniaceae are discussed.

AbstractThis paper provides a revision of the foliicolous representatives of the Gyalectaceae in Costa Rica. Five species of Coenogonium and 13 of Dimerella are distinguished. Coenogonium interplexum, C. interpositum, C. leprieurii, C. linkii and Dimerella vezdana are ubiquitous as to the choice of their substratum, whereas C. moniliforme and Dimerella lutea are facultatively foliicolous. The remainder are typically foliicolous taxa but may occasionally be found on bark. The following species are for the first time reported as foliicolous from Costa Rica: Coenogonium interplexum, C. interpositum, C. leprieurii, C. moniliforme, Dimerella fallaciosa, D lisowskii, and D. aff. pilifera. Three new species are described: Dimerella isidiifera sp. nov. with disciform isidia, D. subzonatasp. nov. with small, bright yellow, dentate apothecia and a whitish prothallus, and D. siquirrensis sp. nov. with large, orange apothecia and a thin whitish prothallus. A key is presented for neotropical foliicolous Gyalectaceae, and notes on the distribution and ecology of the species are given.

This further contribution to the knowledge of the foliicolous lichen flora of Costa Rica provides a detailed account on the genus Fellhanera. In total, 25 species and five undescribed taxa are treated. Ten species are described as new: Fellhanera angustispora sp.n., F. dictyospora sp.n., F. dispersa sp.n., F. emarginata sp.n., F. pilomarginata sp.n., F. longispora sp.n., F. muhlei sp.n., F. montana sp.n., F. verrucifera sp.n., and F. viridis sp.n. New combinations are F. pauciseptata (R. Sant.) R. Lücking comb.n. [Bas.: Bacidia pauciseptata R. Sant.] and F. rubida (Müll. Arg.) R. Lücking comb.n. [Bas.: Patellaria rubida Müll. Arg.]. F. dominicana (Vain.) Vezda is placed into synonymy with F. fuscatula (Müll. Arg.) Vezda, whose type has 7-septate ascospores, and the name F. subfuscatula R. Lücking sp.n. is introduced for the taxon with 5-septate ascospores formerly known as F. fuscatula. F. misionensis Ferraro & R. Lücking ined. and F. sublecanorina (Nyl.) Vezda are reported for the first time from Costa Rica. The formerly invalidly published names F. farinosa nom. nud. and F. pilosa nom. nud. are considered to be synonyms of F. fuscatula (Müll. Arg.) Vezda and F. rhapidophylli (Rehm) Vezda, respectively. Specimens identified as F. tuckeri nom. nud. belong to F. rhapidophylli as well. F. buxi is excluded from the foliicolous lichen flora of Costa Rica. A keys is provided to the complex group of species of Fellhanera with brownish apothecia and 3-septate ascospores. Infrageneric relationships within Fellhanera are briefly discussed, and notes on the ecology of the species are provided.

Long Time

Marine mammals such as whales and dolphins have been known for a long time to host a very specific epizoic community on their skin. Less known however is the presence of a similar community on the carapaces of sea turtles. The present study is the first describing new taxa inhabiting sea turtle carapaces. Samples, collected from nesting olive ridley sea turtles (Lepidochelys olivacea) on Ostional Beach (Costa Rica), were studied using light and scanning electron microscopy. Two unknown small-celled gomphonemoid taxa were analysed in more detail and are described as two new genera, closely related to other gomphonemoid genera with septate girdle bands, such as Tripterion, Cuneolus and Gomphoseptatum. Chelonicola Majewska, De Stefano & Van de Vijver gen. nov. has a flat valve face, uniseriate striae composed of more than three areolae, simple external raphe endings, internally a siliceous flap over the proximal raphe endings and lives on mucilaginous stalks. Poulinea Majewska, De Stefano & Van de Vijver gen. nov. has at least one concave valve, uniseriate striae composed of only two elongated areolae, external distal raphe endings covered by thickened siliceous flaps and lives attached to the substrate by a mucilaginous pad. Chelonicola costaricensis Majewska, De Stefano & Van de Vijver sp. nov. and Poulinea lepidochelicola Majewska, De Stefano & Van de Vijver sp. nov. can be separated based on stria structure, girdle structure composed of more than 10 copulae, raphe structure and general valve outline. A cladistics analysis of putative members of the Rhoicospheniaceae indicates that the family is polyphyletic. Chelonicola and Poulinea are sister taxa, and form a monophyletic group with Cuneolus and Tripterion, but are not closely related to Rhoicosphenia, or other genera previously assigned to this family. Features used to help diagnose the family such as symmetry and presence of septa and pseudosepta are homoplastic across the raphid diatom tree of life.

Abstract A description is provided for Meliola mangiferae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Meliola mangiferae, as with the family Meliolaceae in general, is found on living leaves parasitizing the epidermis and sometimes deeper tissues, but without production of obvious disease symptoms. HOSTS: Mangifera indica, M. rigida and Mangifera sp. (Hansford, 1961). GEOGRAPHICAL DISTRIBUTION: Brazil, British Guiana, Costa Rica, Cuba, India, Indonesia (Java), Jamaica, Malaysia, Panama, Philippines, Puerto Rico, Surinam, Trinidad & Tobago, Venezuela. Meliola mangiferae is found in practically all areas of mango cultivation, with the exception of Africa and Australia (Hansford, 1961). TRANSMISSION: By air-borne ascospores.
