Ashraf A., Habib K. & Khalid A.N. (2022): A new pruinose lichen species in genus Lobothallia (Megasporaceae, lichen forming Ascomycota) from Pakistan - Acta Botanica Brasilica, 36: e2021abb0225 [8 p.]

A new species in the genus Lobothallia (Megasporaceae, lichenized ascomycetes), from Margalla Hills, Pakistan, is described and illustrated here under the name Lobothallia densipruinosa. It is characterized by contiguous, clustered, densely pruinose dark olive apothecia, conidia 6-10 µm long, and large areoles and lobes. Phylogenetic analysis based on ITS-nrDNA sequencing placed our species relative to L. pruinosa. Descriptions and images of the new species are provided, as well as a key for the … Read more...

Thell A. (1995): A new position of the Cetraria commixta group in Melanelia (Ascomycotina, Parmeliaceae) - Nova Hedwigia, 60(3-4): 407-422

The Cetraria commixta group, including four species, is transferred to Melanelia Essl., and the following new combinations are made: Melanelia agnata (Nyl.) Thell comb. nov., Melanelia commixta (Nyl.) Thell comb. nov., Melanelia culbersonii (Hale) Thell comb. nov. and Melanelia hepatizon (Ach.) Thell comb. nov. These new combinations in Melanelia could be supported by similarities in the reproductive structures and other anatomical characters. Typical Melanelia-asci with a small tholus and a … Read more...

Awasthi D.D. (1987): A new position for Platysma thomsonii Stirton - Journal of the Hattori Botanical Laboratory, 63: 367-372

The taxon Platysma thomsotiii Stirton is transferred to the new genus Parmelaria Awas., and a new species Parmelaria subthomsonii Awas. is described. Platysma thomsonii Stirton was apparently named by Stirton (1879) after J. A. Thomson as is clear from the remark after the protologue, “The two preceding spe cies are from a fine collection of foliaceous lichens in the possession of Mr. J. A. Thomson of this city, who secured them several years ago from the Himalayas near Darjeeling”, the two preceding … Read more...

Hopf H., Jones P.G., Goclik E., Aust P. & Rödiger J. (2012): A new polymorph of physcion - Acta Crystallographica Section C, 68(8): o317–o319

The structure of the title compound, 7-methoxy-2-methyl-4,5-dihydroxyanthracene-9,10-dione, C16H12O5, was originally reported by Ulickýet al. [Acta Cryst. (1991). C47, 1879–1881] in the space group P212121 [polymorph (Io)]. The new polymorph, (Im), crystallizes in the space group P21/c. The molecular structures are closely similar, with both –OH groups forming intramolecular hydrogen bonds to one of the neighbouring quinone O atoms, thus slightly lengthening this C=O bond; the pattern of C—C … Read more...

Breuss O. & Haji Moniri M. (2017): A new Placopyrenium species (Ascomycota: Verrucariaceae) from Iran - Herzogia, 30: 177–181

Placopyrenium ariyanense from northeastern Iran is described as new to science. It is characterized by a small, areolate thallus, grey pruinose, black-rimmed areoles, a granule-inspersed, but not chalky medulla, and simple ascospores, which are broader than those in P. iranicum. It is probably a juvenile parasite on crustose lichens. Key words: Pyrenocarpous lichens, fungi, taxonomy. Read more...

Aptroot A. & Yazici K. (2012): A new Placopyrenium (Verrucariaceae) from Turkey - Lichenologist, 44(6): 739–741

The new species Placopyrenium bullatum is described from limestone in Turkey. It is characterized by the immersed ascomata, the areolate and bullate thallus, the often blackened exciple and the 1-septate ascospores. It resembles P. iranicum, but differs by the 1-septate ascospores, the dark exciple and the black mottled medulla. Ig˘dır, lichen, new species, Placidiopsis, taxonomy Read more...

Zheng K.-X., Jiang Y., Jiang J.-X., Huang R., He J. & Wu S.-H. (2019): A new phthalazinone derivative and a new isoflavonoid glycoside from lichen-associated Amycolatopsis sp. - Fitoterapia, 135: 85–89

A new phthalazinone derivative, named amycophthalazinone A (1), and a new isoflavonoid glycoside, 7-Omethyl- 5-O-α-L-rhamnopyranosylgenestein (2), along with an isoflavonoid glycoside, 7-O-α-D-arabinofuranosyl daidzein (3) firstly found from natural sources, and eight known compounds (4–11), were isolated from the culture broth of the lichen-associated Amycolatopsis sp. YIM 130642. The structures of new compounds were elucidated on the basis of spectroscopic analysis. Compound 1 was the first … Read more...

Huynh B.L.C., Bui V.M., Nguyen T.H.T. & Nguyen K.P.P. (2021): A new phenolic compound from the lichen Parmotrema praesorediosum (Nyl.) Hale - Vietnam Journal of Chemistry, 59(1): 47–51

Chemical investigation of the lichen Parmotrema praesorediosum (Nyl.) Hale led to isolate six phenolic compounds including praesorediosic (1), orcinol (2), orselinic acid (3), lecanorin (4), isolecanoric acid (5) and virensic acid (6). Among them, compound 1 appeared to be found for the first time in the nature. The structure of these compounds was elucidated by spectroscopic analyses of HRESIMS and NMR as well as the comparison of their NMR data with those in the literature. These compounds were … Read more...
