Ascomycetes from the Qilian Mountains, China – Hypocreales

To investigate fungi from the Qilian Mountains in Gansu Province, ascomycetous specimens were collected and hypocrealean fungi were examined. Eighteen species belonging to six genera in the families Hypocreaceae and Nectriaceae were identified, including 11 species of Hypomyces and Trichoderma in Hypocreaceae and seven species of Nectria, Stylonectria, Thelonectria, and Thyronectria in Nectriaceae. Among them, Stylonectria qilianshanensis and Trichoderma gansuanum are new to science. DNA sequence analyses of combined ACL1, ITS, RPB2, and TEF1 regions confirmed their taxonomic placements. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces tremellicola is reported for the first time in China.

Hericium cirrhatum, a widespread but locally rare tooth fungus is reported for the first time from Pakistan. This species is characterized by white to cream semicircular basidiomata (usually arranged in tiers) with a granular to slightly spiny sterile upper surface, a fertile under surface with 10–15 mm long pointed spines, and ellipsoid to subglobose basidiospores. Morphological characters and DNA sequence analyses inferred from the nuclear ribosomal internal transcribed spacer region (nrITS) confirm the identity of the taxon.

The crab spider genus Tarrocanus Simon, 1895 currently includes two species: T. capra Simon, 1895 and T. viridis Dyal, 1935. Recent field work revealed the presence of a new species, providing an opportunity to review the genus. The new species is described as T. jaffnaensis sp. nov. Furthermore, the male of T. capra is described for the first time, and taxonomic notes on Alcimochthes Simon, 1885 and Domatha Simon, 1895 are given, both presumably being close relatives of Tarrocanus. Tarrocanus viridis Dyal, 1935 is considered as nomen dubium.

During field surveys in central and southwestern China, three new species, Trichoderma acremonioides, T. rugosum and T. subalni were discovered. They are located respectively in the Viride, Longibrachiatum and Harzianum clades. Trichoderma acremonioides from southwest of China forms reddish brown ascomata, hyaline ascospores and very simple conidiophores. Trichoderma rugosum occurring in Hubei and Tibet is specialized by stroma cortical tissue of textura intricata, hyaline ascospores, and trichoderma-like conidiophores. Trichoderma subalni from Tibet is characterized by rufous stromata, green ascospores, trichoderma-like conidiophores, and slow growing on standard media. Detailed morphological distinctions between the new species and their close relatives are discussed. Their phylogenetic positions were determined based on sequence analyses of RPB2 and EF-1α genes.

A New Species

The orchid genus Gastrodia Brown (1810: 330) comprises approximately 50 species with a broad Old World distribution (Pridgeon et al. 2005, Cribb et al. 2010, Kenji 2014). Currently, there are at least 20 accepted species of Gastrodia recorded from China (Chung & Hsu 2006, Chen et al. 2009, Hsu & Kuo 2010, 2011, Yeh et al. 2011, Hsu et al. 2012, Tan et al. 2012, Hu et al. 2014). During our field surveys of Chinese traditional medicine in Huaping National Nature Reserve, Guangxi Zhuangzu Autonomous Region, China, a Gastrodia was spotted setting fruit in the past few years. Finally, we were able to observe it flowering in August 2014. After careful comparison morphological study with its close relatives (Averyanov & Efimov 2006) and three other species of Gastrodia recorded in Guangxi, namely Gastrodia damingshanensis A.Q.Hu & T.C.Hsu (2014: 256), Gastrodia elata Blume (1856: 174) and Gastrodia menghaiensis Z.H.Tsi & S.C.Chen (1994: 559), we confirmed this Gastrodia as a new species and thereby a new member to the flora of Guangxi. A detailed description, illustration and ecological information are presented below. We also discuss the remarkable dimorphic columns of this new species, which are documented in Gastrodia for the first time.

Abstract. To our knowledge, the Qilian Mountains in NW China have been investigated with respect to Recent or sub-Recent ostracods for the first time. The Qilian Mountains (95–103°E/37–40°N) extend along the northeastern margin of the Tibetan Plateau reaching a maximum altitude of 5826 m above sea-level (m asl).In September 2001, surface mud from the bottom of various water bodies including brooks, rivers and small shallow meadow and oxbow pools were sampled at an altitude ranging from 2900 m to 3570 m asl. In addition, surface mud samples and short cores were obtained from the small (c. 1 km2) and shallow (<0.4 m) freshwater Lake Luanhaizi situated at about 3200 m asl.Ostracod valves were usually abundant in all of the 32 samples and comprised the taxa listed in Table 1, some of which are illustrated in Plate 1.The recorded taxa are mainly distributed in the holarctic realm but Fabaeformiscandona danielopoli and Ilyocypris echinata appear to be restricted to the cold mountainous regions in China (Huang, 1985; Wang & Zhu, 1991; Sun et al., 1995; Yin & Martens, 1997).Following the first survey, a 14 m long core was drilled in Lake Luanhaizi in January 2002 which is currently under multidisciplinary investigation to reconstruct the Holocene vegetation and climatic history of the Qilian Mountains.

The Qilian Mountains

Abstract. In this study, we analysed the role of vegetation in the recycling of water in two endorheic watersheds in northwest China, namely within the Shiyang and Hei River watersheds (Gansu Province), along a gradient of elevation zones and within-zone landcover types. Each watershed was subdivided into four elevation zones representative of (i) oasis plains and foothills, and (ii) low-, (iii) mid-, and (iv) high-mountain elevations. By means of monthly summaries of enhanced vegetation index (EVI), DEM-height values, terrain orientation, and a decision-tree classifier, landcover in the study area (consisting of oases, deserts, and adjoining Qilian Mountains) was classified into 11 unique landcover types. Comparison of monthly vegetation phenology with precipitation and snowmelt dynamics within the same watersheds over a ten-year period (2000–2009) suggested that the onset of the precipitation season in the mountains (in May) was triggered by the greening of vegetation and increased production of water vapour at the base of the mountains. Seasonal evolution of in-mountain precipitation correlated fairy well with the temporal variation in oasis-vegetation coverage and phenology (of crops and grasses) characterised by monthly EVI, giving r2 values of 0.65 and 0.85 for the Shiyang and Hei River watersheds, respectively. Generally, comparisons between same-zone monthly precipitation volumes and EVI provided weaker correlations. Start of the growing season in the oases was shown to coincide with the discharge of meltwater from the low- to mid-elevations of the Qilian Mountains in mid-to-late March. Comparison of water volumes associated with in-mountain production of rainfall and snowmelt with that associated with actual evapotranspiration revealed that about 90% of the water flowing downslope to the oases was eventually returned to the Qilian Mountains as water vapour generated in the lowlands.
