Material collections, greenhouse planting experiment, fungal
strains, media and culture conditions
The records on the geographical distributions and substrate information
of A . vulgare and S . stephanocystis were
extracted from data deposited in the Global Biodiversity Information
Facility (GBIF; https://www.gbif.org/). The information on substrates
and distributions of the following four species A .orientale , A . microsporum , S .luchuensis and S . pachycystidiatus was primarily
from the published literature and our own observations during field
investigations in China. In order to directly observe the
characteristics of pinecone decomposition by Auriscalpium andStrobilurus , a planting experiment was conducted in the
greenhouse using the cones of P . armandii fully colonized
by A . microsporum collected in the forest in which bothAuriscalpium and Strobilurus existed.
All seven strains used for de novo sequencing were dikaryotic strains
isolated directly from the fruiting bodies from wild mushrooms. Among
these, the following five species and strains were collected in Yunnan
Province, China: A .microsporum(strain AU-H-210),A .orientale (strain AU-Y-A),S .luchuensis (strain Y-Y-2D),S .pachycystidiatus (strain Y-H-6C) andS .orientalis (strain K-1-1). The remaining two A .vulgare (CBS 236.39) andS .stephanocystis (CBS 113577) were obtained from the Westerdijk
Fungal Biodiversity Institute (CBS, Fungal Biodiversity Centre in
Netherlands). The strains were stored
at 4 °C on MEA solid medium (1 % malt extract, 0.1 % peptone and 1.5
% agar). Vegetative mycelia of those strains were cultivated in MEA
liquid medium (1 % malt extract and 0.1 % peptone) in the dark at 23
°C for 7–25 days, and then the mycelia were collected for DNA
extraction and whole genome sequencing (Mayjonade et al., 2016).
