A. niger_ and _A. flavus_, with the diameters of the inhibition zones of 10 mm and 15 mm, respectively, which were higher than those obtained in this study. However, according to [PERSON] et al. [32], the methanolic extracts of _C. vulgaris_ did not suppress the growth of _A. niger_ and _A. flavus_. [PERSON] et al. [15] found that the supernatant of _C. vulgaris_ 025 and _C. vulgaris_ 012 inhibited the growth of _A. niger_, with the diameters of the inhibition zones of 11 mm and 14 mm, respectively, which are consistent with this experiment. However, the supernatant of another strain of this species (_C. vulgaris_ 030) did not inhibit _A. niger_, thereby showing strain-specific activity. Some authors described a time- and concentration-dependent inhibitory activity of the _C. vulgaris_ supernatant on the mycelial growths of _A. niger_ and _F. oxysporum_. _C. vulgaris_ supernatant inhibited the growth of _Alt. alternata_ as well, but with a less pronounced time- and concentration-dependent effect [17; 33]. [PERSON] et al. [34] also found antifungal activity of the aqueous extract of _C. vulgaris_ biomass on _A. niger_ with a very large diameter of the inhibition zone--51 mm. There are no literature data about the activity of _C. vulgaris_ extracts against _P. chrysogenum_, _A. carbamarius_ and _A. parasiticus_. The above-mentioned methods of measuring the antifungal activity of _C. vulgaris_ are very diverse, which could explain the differences found with this experiment. Methanolic extracts of _S. dimorplus_ were inhibitory only against _A. niger_ and _P. chrysogenum_, with small zones of inhibition--8.2 \(\pm\) 0.6 mm and 8 \(\pm\) 0 mm, respectively. The differences with negative control (methanol) values were not statistically significant (Table 1). [PERSON] et al. [15] also reported that the supernatant of _Scenedensmus obliquus_ 019 was active against _A. niger_, with a zone of inhibition of 8 mm. [PERSON] et al. [35] found that the ethanolic and hexane extracts of _Scenedensmus_ sp. showed a large difference between their antifungal activity against _F. oxysporum_ and _A. niger_, although both extracts were inhibitory towards these fungi. Contrary to the aforementioned results, [PERSON] and [PERSON] [31] established a lack of activity of 5% methanolic extracts of _Scenedensmus quadricauda_ against _A. niger_, as well as a good effect against _A. flavus_ with a large inhibition zone diameter--20 mm. [PERSON] et al. [16] found the antifungal activity of _Scenedensmus obliquus_ methanolic extracts against _A. flavus_ and _A. parasiticus_ to exhibit inhibition zone diameters of 9.7 and 10.7 mm, respectively, as well as a lack of effect on _A. ochracus_ and _A. carbamarius_. There are some discrepancies regarding the antifungal potential of _S. dimorplus_ and the literature data, probably due to the different species of _Scenedensmus_ examined, as well as the various methods used for measuring antifungal activity. The methanolic extracts of _L. minuta_ showed minimal activity against _A. ochracus_, _P. chrysogenum_ and _Alt.
