新疆拟橙衣属地衣研究

报道新疆拟橙衣属地衣的6个分类单位。其中南方拟橙衣Fulgensia australis,荒漠拟橙衣F.desertorum和苔生拟橙衣F.schistidii为中国新记录种。在形态学、解剖学、化学及生态学方面对它们进行了简短的论述。此外,还提供了形态特征和内部解剖特征照片以及新疆种类的分种检索表。研究所用的标本采自托木尔峰、铁力买提达坂、阿尔金山和准葛尔盆地等,保存于新疆大学生命科学与技术学院地衣标本室。     

贵阳地区碳酸盐岩表生地衣调查初报

对贵阳地区碳酸盐岩表生地衣资源进行初步调查,鉴定出4科,4属,共计7个种。其中两个是中国新记录种,即:蓝藻橙衣和石灰瓶口衣。瓶口衣属、黄烛衣属、凹盘衣属以及该文所描述的7个种都是贵州首次报道。对壳状地衣体在碳酸盐岩风化过程中的作用进行了初步分析。

Taxonomic and functional diversity in <Emphasis Type="Italic">Calogaya</Emphasis> (lichenised Ascomycota) in dry continental Asia

The genus Calogaya (Teloschistaceae, Xanthorioideae) was established to accommodate mainly epilithic lichens with lobate thalli, previously regarded as the “Caloplaca saxicola group.” Data supporting the recognition of this new genus came from European lichens, and although the genus is soundly based, we have found in Asia numerous epiphytic lineages and lineages with reduced, non-lobate thallus in dry continental areas. The taxonomic and functional diversity of Calogaya is distinctly higher in steppe and desert areas of Asia than in the less arid regions of Europe. We sampled 238 specimens, mostly from arid regions of north-western China, Iran, southern Siberia and Turkey. Three nuclear DNA loci were analysed separately and jointly by Bayesian inference, maximum likelihood and *BEAST approaches. Delimitations of 28 putative species were tested by BP&P multispecies coalescent model with joint analysis of species delimitation and species-tree estimation. Finally, we recognised 22 taxonomic units: 16 are at species rank, 3 are treated as subspecies and 3 are complexes, treated here as a single entity, but in reality probably including more than one species. Calogaya altynis, C. biatorina subsp. asiatica, C. decipiens subsp. esorediata, C. haloxylonis, C. orientalis, C. xanthoriella and C. xinjiangis are newly described. Caloplaca zoroasteriorum is combined into Calogaya, and Calogaya persica is reduced to a subspecies. The taxonomic status of Calogaya saxicola is unclear, and the name is employed here “sensu lato” for several non-monophyletic epilithic lineages with short-lobed thalli. Calogaya biatorina and C. ferrugineoides are the two other heterogeneous taxonomic units probably including more species.
