    地衣型真菌;新疆;分類學(xué)

    The genusFarnoldiaHertel was segregated from the genusMelanoleciaHertel in 1983[1]. Previously only six species have been reported from Europe, North and South America, and Antarctica[2-3]. And has not been found in China. The family Lecideaceae Chevall. contains about 23 genera and 220 species, and 53 taxa of 11 genera in Lecideaceae have been reported in China[4-7]. During our research on the lichens of Lecideaceae in Xinjiang, the genusFarnoldiaand the speciesFarnoldiamicropsisare reported as new to China.

    1 Materials and methods

    The examined specimens are preserved in SDNU (the Lichen Section of Plant Herbarium, Shandong Normal University). Their morphological and anatomical characters were examined under a stereo-microscope (Olympus SZ) and a polarizing microscope (Olympus CX21). Color reactions (spot tests) were made using standard methods. The chemical constituents were identified using thin layer chromatography (TLC)[8]. Photos were taken under Olympus SZX16 and BX61 with DP72.

    2 Results and discussion

    FarnoldiaHertel Mitt. bot. StSamml., Münch. 19: 442 (1983)

    Type species:Farnoldiajurana(Schaerer) Hertel

    Thallus crustose, on or in rocks; upper surface white, sooty white, or yellow-brown; isidia and soredia absent; medulla I+blue. Apothecia adnate or between the areolae; margin present and even; disk black or sometimes pruinose; exciple carbonaceous; hypothecium hyaline or blackish brown; paraphyses coherent, branching and ana-stomosing; asci with an I+dark blue central cylinder in an otherwise I+pale blue tholus; spores simple, ellipsoid, with gelatinous halo, middle-sized, 10-33 μm long. Conidia bacilliform, (5-13)×1 μm.

    Algae:Pseudotrebouxia.

    Habitat: On calcium-bearing rocks.

    Notes: This genus is similar in its characters toPorpidiabut differs in the entirely dark exciple in which hyphe are not distinguishable but which is continuous with the dark hypothecium. It is also similar toClauzeada. However,Clauzeadahas a I-medulla, brown to dark brown exciple. Comparison of characters ofFarnoldiaand similar genera are shown in Table 1. A key toFarnoldiaand related genera is also provided.Farnoldiamicropsis(A. Massal.) Hertel, Mitt. bot. StSamml., Münch. 19: 443 (1983)( Fig.1, A,B )

    Thallus crustose, thin to moderately thick, to 1.5 mm thick, white, sooty white, sometimes stained from substratum, areolate from smooth to bullate in thick material; no hypothallus.

    Apothecia to 1.2 mm broad, adnate or between the areolae, black, with prominent margin; exciple black, 40-60 μm wide; hypothecium pare ochre, sometimes contains green; epihymenium green-black to brown-black, occasionally with light dead overlayer; hymenium (80-120)μm; subhymenium 30-60 μm, pale; paraphyses 2 μm,tips to 3.5 μm, anastomosing; asci clavate; spores ellipsoid or asymmetric, thin-walled, halonate when young, (15-27)× (7-16) μm.

    Key toFarnoldiaand related genera

    This is a preliminary key to the genera of Lecideaceae s. lat. that appear closely related toFarnoldia.

    1 Growing on acidic rock (exceptionally on calciferous siliceous rock)

    Porpidiap.p.

    Growing on limestone (and other rock types very rich in CaCO3)

    2

    2(1) Exciple thick and carbonaceous throughout, clearly separated from the paler hypothecium. Hypothecium hyaline or blackish brown. Apothecia sessile with a black or bluish pruinose disc, never becoming brownish when wet

    Farnoldia

    Excipulum not carbonaceous throughout

    3

    3(2) Hypothecium concolorous with exciple; brown and or olivaceous pigments present internally. High montane to alpine regions

    Porpidiap.p.

    Hypothecium hyaline or paler than exciple; only brown, K-pigments present internally. In lowland to high montane regions

    Clauzadea

    A. Thallus; B. Section of apotheciaFig.1 Morphological and anatomical structures of Farnoldia micropsis(20140906 SDNU)

    Chemistry: Medulla I+, K-, C-, KC-. Chemical constituent: none.

    Notes:Farnoldiamicropsisis similar toF.similigenain having a white, thick and bullate thallus. However,F.similigenahas a smaller apothecia (to 0.7 mm broad), a thiner ascospores [(10-22)×(4-7) μm], and a lower hymenium (60-80 μm). This species grows on calcium-bearing rocks. It is a circumpolar arctic and alpine species. It is known in Colorado, Montana, Utah, Alberta, and Oregon[10]. It is also found in eastern Greenland, Sweden and Slovenia.
