白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

Clitocybe strigosa is an agaric fungus in the family Tricholomataceae found in temperate and boreal European forests. The specific epithet strigosa refers to a stiff, bristly texture suggesting the cap surface or stipe may bear fine, erect hairs or fibrils distinguishing it from smoother relatives. It inhabits woodland floors, grassy forest margins, and clearings, fruiting in autumn when moisture conditions favor fruiting body development. The general morphology follows the Clitocybe pattern: a depressed to funnel-shaped cap with decurrent gills and a central stipe, in pale to greyish-buff tones. As a saprotrophic fungus, C. strigosa decomposes leaf litter, woody debris, and soil organic matter, contributing to the carbon and nitrogen cycling that sustains forest ecosystems. The genus Clitocybe encompasses dozens of European species, many of which require careful microscopic examination and consideration of substrate, odor, and spore features for reliable identification. Documentation of less common species like C. strigosa contributes to understanding the full scope of European fungal biodiversity.
