# Fungi of the _Trichoderma_ Genus: Future Perspectives of Benefits in Sustainable Agriculture
## 3 Occurrence and Abundance of _Trichoderma_ Fungi in Different Environments
koningiopsis_ (18%), and _T. virens_ (18%). [PERSON] et al. [46] isolated a total of 54 fungi from crop soil samples in Brazil. The researchers documented that _T. hamatum_ and _T. koningiopsis_ were present only in garlic fields, whereas _T. afroharzianum, T. asperellum, T. erinaceum_, and _T. lentiforme_ were present only in onion fields. In addition, [PERSON] et al. [45] proved that the species biodiversity of the soil microbiome is related to the season. Their observations showed that during the summer season, the soil was characterized by the greatest diversity of _Trichoderma_ (17 species). During the autumn, only nine species of these microorganisms were isolated from the samples. _Trichoderma_ sp. can also be isolated from soil not previously intended for cultivation, as proved by [PERSON] et al. [47] (Table 1). The authors obtained 13 isolates of these fungi from 65 samples of such soil, among which _T. asperellum, T. harzianum, T. longibrachiatum_, and _T. orientalis_ showed the highest occurrence. Similarly, [PERSON] et al. [48] isolated 19 species of _Trichoderma_ from non-agricultural areas in South Africa. [PERSON] and [PERSON] [49] obtained _T. asperellum, T. citrinoviidae, T. harzianum, and T. lixii_ from lignocellulosic composets. In turn, [PERSON] et al. [50] isolated strains of _T. atroviride, T. citrinoviidae, T. harzianum_, and _T. koningiopsis_ from the walls of mold-covered buildings in Canada. [PERSON] et al. [51] obtained _T. atroviride, T. citrinoviride, T. paravridescens_, and _T. trixiae_ from settled dust, mineral wool, and exhaust air filters found in buildings in different Finnish cities. \begin{table}
