Table 1: Identification of fungi isolated at the NW and SE study sites of SMFC by rDNA analysis. (a) Morphotypes isolated at the NW site. (b) Morphotypes isolated at the SE site. In the Morphotype column, bold indicates dematiaceous filamentous fungi; italics indicate dematiaceous meristematic fungi and black yeasts. Most of the identified genera (8 out of 11, 72.7% of the genera at NW; 9 out of 13, 69.2% at SE) and species are known as dematiaceous (Table 1). Among these, one strain at NW (M1) and two strains at SE (SM and NT-S-5, the latter based on morphology) were meristematic fungi, while two other strains at SE (SO and SP, both identified as _Aureobasidium pullulans_) showed a yeast-like growth (Supplementary Figure S5).
