### The Cultured Microbiome of A. fliculoides  
The isolation yielded in 58 microbial isolates, among which 15 were obtained from the interior of the plant. We noticed differences in the morphology of the colonies, which suggests affiliation of the isolates to different taxonomic groups. The morphology of the obtained isolates is summarized in Table 2. \begin{table}

Table 2: Morphological traits of the isolates. The isolates displayed a wide range of colony sizes ranging from \(<\)1 mm to ca. 0.5 mm. More than 40% were both punctiform and small, above 20% were moderate in size, and the largest colonies constituted approximately 14%. The epiphytes showed the same pattern, whilst 46% of the endophytes were the smallest, 20% were small, 27% were moderate, and only ca. 7% had a large size. The circular shape was dominant in the studied pool of microorganisms (60%), with substantially higher counts recorded for the endophytes (87%) than the epiphytes (51%). Oval and irregular shapes accounted for 19% of each of these shapes. Only one epiphytic isolate formed filamentous colonies (2%). The epiphytic microorganisms formed oval and irregular shapes in 26% and 21% cases as well. The endophytes did not form oval and filamentous colonies and an irregular form was recorded in 14% of these microorganisms. In the case of surfaces, we distinguished dull-glistering and rough-smooth combinations. The glistering/smooth surface accounting for 50% of all isolates was the most abundant (35% and 93% of the epiphytes and endophytes, respectively). The next two abundant surfaces were glistering-rough (22%, 28%, and 6% for the total microbiome, epiphytes, and endophytes, respectively) and dull/smooth (19% of all microbes).
