摘要

Placopsis antarctica是一种拟鸟地衣，长期以来一直与P. contortuplicata I. M. Lamb混淆。在本研究中，我们着重研究了南极拟南芥的形态特征。我们报道了南极p.a nterum菌体的优势形态结构:头状体、边缘裂片、单胞坑和soralia的生物统计学数据。在南极乔治国王岛采集南极p.a nantarctica菌体，并在实验室采用数码显微镜方法对其进行分析。头中央呈椭圆形，后呈圆形。平均长/宽为2.424/1.720 mm。边缘裂片在先端(1.415 mm)比基部(0.495 mm)宽。侧头头较小，平均长/宽为1.034/0.610 mm。

Biometrical analysis and thallus morphology characteristics of Placopsis antarctica from King George Island, Antarctica ( Short Communication )

Placopsis antarctica is an ornithocoprophilous lichen that has been for a long time confused with P. contortuplicata I. M. Lamb. In our study, we focused on morphological characteristics of P. antarctica thalli. We report biometrical data on dominant morphological structures of P. antarctica thallus: cephalodia, marginal lobes, sorediate pits and soralia. Thalli of P. antarctica were collected at the King George Island, Antarctica and analyzed in a laboratory using a digital microscopy approach. Central cephalodium was found rather elliptic then round-shaped. Mean length/width was found 2.424/1.720 mm. Marginal lobes were found wider at the apex (1.415 mm) than basal part (0.495 mm). Side cephalodia were smaller, their mean length/width was found 1.034/0.610 mm.
