安徽皇埔山大型真菌区系地理成分分析

Geographical components of macrofungal flora in Huangpushan Nature Reserve,Anhui Province of East China

为了解安徽皇埔山自然保护区大型真菌区系多样性,对该地区的大型真菌区系地理成分进行了分析。结果表明:该地区共有大型真菌103种,分属于24科48属,其中优势科为Tricholomataceae(14种,占13.59%)、Russulaceae(11种,占10.68%)、Cortinariaceae(10种,占9.71%)和Polyporaceae(10种,占9.71%);优势属为Lactarius(8种,占7.77%)、Psathyrella(6种,占5.83%)、Cortinarius(5种,占4.85%)和Marasmius(5种,占4.85%);从属的区系地理成分上初步划分为世界广布成分(58.33%)、泛热带成分(29.17%)、北温带成分(10.42%)和热带-亚热带成分(2.08%);从种的地理成分上划分为:世界广布种(45种,占43.69%)、热带-亚热带分布种(31种,30.1%)、北温带分布种(24种,23.3%)及欧亚-北美-澳大利亚分布种(3种,2.91%)等分布型;皇埔山大型真菌的区系地理成分主要是以世界广布种为主,其次是热带-亚热带成分和北温带成分。

To understand the diversity of macrofungal flora in Huangpushan Nature Reserve of Anhui Province, an investigation was conducted on the geographical components of the flora. A total of 103 macrofungal species were identified, belonging to 48 genera of 24 families. The dominant families were Tricholomataceae （14 species, 13.59%）, Russulaceae （11 species, 10.68%）, Cortinariaceae （10 species, 9.71%）, and Polyporaceae （10 species, 9.71%）, and the dominant genera were Lactarius （8 species, 7.77%）, Psathyrella （6 species, 5.83%）, Cortinarius （5 species, 4.85%）, and Marasmius （5 species, 4.85%）. Geographically, the genera could be divided into four components, i.e., cosmopolitan （58.33%）, pantropical （29.17%）, north temperate （10.42%）, and tropical or subtropical （2.08%）, and the species could be grouped into four components, i.e., cosmopolitan （45 species, 43.69%）, tropical or subtropical （31 species, 30.1%）, temperate （24 species, 23.3%）, and Eurasia North America Australia （3 species, 2.91%）. It was suggested that the geographical components of macrofungal flora in Huangpushan Nature Reserve were largely cosmopolitan, followed by tropical or subtropical and by north temperate.
