Bactrospora myriadea Egea & Torrente 1993
No full textBactrospora myriadea (Fée) Egea & Torrente In the Paleotropics Bactrospora myriadea was previously known from India (Egea & Torrente 1993), China, the Seychelles and Singapore (Aptroot & Sipman 2001, Sipman 2010). It is a new addition to the Thai lichen biota. Specimen examined:— THAILAND. Rayong Province: Muang District; Pagoda Klang Nam near Paknam, in an old but very polluted mangrove forest on Rhizophora apiculata, ± 5m, 12°40’06’’ N, 101°14’27’’ E, 27 February 2011, K. Kalb & P.

Orcularia elixii Kalb & Giralt 2011, sp. nov.
No full textOrcularia elixii Kalb & Giralt, sp. nov. Mycobank MB 563559 Sicut O. insperata, sed ascosporis minoribus differt. Type:— Australia, New South Wales, Patonga, eastern side of Patonga Creek, ca. 40 km N of Sydney, on Avicennia marina at the edge of a mangrove forest; 33°33’S, 151°16’E, K. & A. Kalb 26226 & A. & P. Archer (CANB — holotype; hb. Kalb—isotype). Etymology:—The new species is named after our good friend and colleague John (Jack) Elix (Canberra) in honour of his many contributions to Austral lichenology. Thallus corticolous, grey to dark-brownish grey because of a brown lichenicolous fungus growing on it, very thin, up to 80 µm thick, smooth to slightly warty. Prothallus absent. Algae chloroccoid 8–13 µm diam. Apothecia 0.15–0.25(–0.3) mm diam., lecideine, adnate to sessile, dark brown to black; disc dark brown or black, epruinose, concave to flat; proper margin thin, persistent. Proper exciple poorly developed, 25–40 µm thick, inner part colourless, outer part brown. Hypothecium 30–50(–70) µm high, brown. Hymenium 60–70 µm high, not inspersed. Epihymenium brown. Apical cells of the paraphyses 2–4 µm broad, brown. Asci 8- spored, Bacidia- type. Ascospores 1-septate, (10–)12–15(–16.5) × (5–)6–7.5(–8.5) µm, Orcularia - type, olive, later pale brown, spore wall smooth, young ascospores with lumina connected by a long isthmus; mature ascospores with a short isthmus or without isthmus connecting the lumina. Pycnidia and conidia not seen. Chemistry: Spot tests all negative, no lichen substances detected by TLC. Notes:—The species is mainly characterized by the small apothecia and the small uni-septate ascospores. It is morphologically very close to O. insperata but differs by the smaller ascospores which further when mature have larger lumina (lateral inner walls less thickened).Published as part of Kalb, Klaus & Giralt, Mireia, 2011, Orcularia, a segregate from the lichen genera Buellia and Rinodina (Lecanoromycetes, Caliciaceae), pp. 53-60 in Phytotaxa 38 on page 56, DOI: 10.11646/phytotaxa.38.1.8, http://zenodo.org/record/489464
Eschatogonia dissecta Timdal & R. Sant.
No full textEschatogonia dissecta Timdal & R. Sant. This lichen was recently described by Timdal and reported from Peru, French Guiana and Venezuela (Timdal 2008). The material cited below matches the description by Timdal (2008) in all respects. We found homosekikaic acid and hyperhomosekikaic acid as major substances and sekikaic acid as a trace substance (TLC). The latter was not mentioned by Timdal. Eschatogonia dissecta is a new addition to the Brazilian lichen biota. Specimen examined:— BRAZIL. Mato Grosso: Serra dos Coroados; Chapada dos Guimarães, trail down to the waterfall ‘ Véu de Noiva’ of Rio Coxipó, in a dark tropical rainforest, 575 m, 15°30’ S, 55°40’ W, 7 July 1980, K. Kalb & M.

Coenogonium pineti Lucking & Lumbsch 2004
No full textCoenogonium pineti (Schrad. ex Ach.) Lücking & Lumbsch A careful comparison of the specimen cited below and European material of this cosmopolitan species revealed them to be identical. It is probably not rare in Thailand, but due to its very small, pale apothecia it is easily overlooked. Coenogonium pineti is a new addition to the Thai lichen biota. Specimens examined:— THAILAND. Trat Province: Laem Ngob District; Black sand beach near Tumbol Laem Ngob, in an old ± disturbed mangrove forest with dominant Rhizophora apiculata, Rh. mucronata, Lumnitzera racemosa and Avicennia marina, ± 3 m, 12°10’11’’ N, 102°24’27’’ E, 25 February 2011, K.
