Supplement 1. Fungal taxa and their abundances.

File List data.txt (MD5: c59bbc959c1dd3045dd953347a84e439) Description The data.txt file is a tab-separated text file. This file contains a record for each fungal species identified by Sanger Sequencing in this study. For each record, the following information is given: Genus Name = name of fungal genus Species Name = name of fungal species GenBank Nearest Match = GenBank accession number for best match Proportionate Abundance, Field Survey = proportion of mycorrhizal field survey root tips identified as this species Proportionate Abundance, Bioassay = proportion of mycorrhizal bioassay root tips identified as this species Ectomycorrhizal Status = designation as either mycorrhizal or non-mycorrhizal based on Comandini et al. (2012) as described in methods in main text Native Status = designation as either native or non-native based on the NZFungi database, the GenBank reported location of the closest matching sequence, and lists of McKenzie et al. (2000) and Orlovich and Cairney (2004), as described in methods in main text Endemic Status = designation as either endemic or non-endemic based on the NZFungi database, the GenBank reported location of the closest matching sequence, and lists of McKenzie et al. (2000) and Orlovich and Cairney (2004), as described in methods in main text

data.txt 为制表符分隔文本文件。本文件为本研究中通过桑格测序（Sanger Sequencing）鉴定的每一种真菌物种生成一条记录。每条记录包含如下信息：
属名：真菌属的名称
种名：真菌种的名称
GenBank最近匹配序列（GenBank）：最优匹配序列的GenBank登录号
相对丰度（野外调查）：野外调查菌根根尖样本中被鉴定为该物种的占比
相对丰度（生物测定）：生物测定菌根根尖样本中被鉴定为该物种的占比
外生菌根状态：依据正文方法部分中提及的Comandini等（2012）的研究标准，将该物种标注为菌根型或非菌根型
本土状态：依据正文方法部分所述的NZFungi数据库、GenBank所报道的最优匹配序列的来源位置，以及McKenzie等（2000）与Orlovich及Cairney（2004）的名录，将该物种标注为本土型或非本土型
特有状态：依据正文方法部分所述的NZFungi数据库、GenBank所报道的最优匹配序列的来源位置，以及McKenzie等（2000）与Orlovich及Cairney（2004）的名录，将该物种标注为特有型或非特有型
