Zwackhiomyces turcicus sp. nov. ( Ascomycota , Xanthopyreniaceae ) from Turkey

Zwackhiomyces turcicus is described as new from the thallus of Physcia magnussonii from southern Turkey. The new species produces one of the largest ascomata in the genus and is easily differentiated from Z. physciicola (described from Physcia caesia) by its larger verruculose ascospores and thinner interascal filaments.

Henfellra muriformis gen. et sp. nov., a New Dictyosporous Pycnidial Fungus on Candelariella, with a Key to the Lichenicolous Fungi Known from that Genus

Abstract: Hawksworth, D. L., Halıcı, M. G., Kocakaya, Z. & Kocakaya, M. 2016. Henfellra muriformis gen. et sp. nov., a new dictyosporous pycnidial fungus on Candelariella, with a key to the lichenicolous fungi known from that genus. — Herzogia 29: 329–336. The new generic name Henfellra gen. nov. is introduced for a new species of pycnidial fungus with hyaline muriform euseptate conidia, H. muriformis sp. nov., discovered on Candelariella antennaria in Turkey. This is the first lichenicolous fungus with muriform conidia to be recognized, and the separation from non-lichenicolous pycnidial genera with muriform conidia, such as Camarosporium, is discussed. A key to the 16 lichenicolous fungi now known to occur on Candelariella species worldwide is provided, and it is noted that the generic placement of several of those will need to be reassessed as they do not appear to be congeneric with the type species of the genera in which they are currently placed. Interestingly, several rather widespread lichenicolous genera have yet to be encountered on the genus, and few are known from the three other genera of Candelariellaceae; whether this is attributable to antifungal properties of the pulvinic acid derivatives they contain merits exploration.

New or Otherwise Interesting Records of Cladonia Species from Turkey

Abstract: Kocakaya, M., Halıcı, M. G., Ahtı, T. & Kocakaya, Z. 2018. New or otherwise interesting records of Cladonia species from Turkey. – Herzogia 31: 327–331. Six Cladonia species (C. conista, C. graeca, C. magyarica, C. peziziformis, C. scabriuscula and C. subturgida) are reported from Turkey; C. graeca, C. peziziformis and C. subturgida for the first time, for which comments on their habitats, substrates and distribution are provided.
