### Distribution of Fungal Entries in Different Environments  
The distribution of the sites among the environmental categories revealed a predominance of wall painting recorded in C-NHE, which alone accounted for 54% of the sites. The hypogean environments accounted for 36.5% of the sites, distributed between C-HE (18.9%) and NC-HE (17.6%). The remaining two categories, SC-NHE and O-SPE, were less represented, comprising 4.1% and 5.4% of the sites, respectively. The cluster analysis at the level of different sites resulted in a general dispersion, with no distinct clusters retrieved. Several clusters consisted of one or few sites highly different one to each other (13-11-14-3-15-10-9-7-12). Other clusters (4-5-6) were slightly more similar to each other and contained many entries (Figure 5).

In the blue rectangle Cuba. The contingency table highlighted that the obtained clusters did not have a strong correlation with the suggested environmental categories (Table 2). However, some clusters showed some affinities: cluster 15 with cat. 4 (SC-NHE) (aff. index 17); cluster 6 with cat. 5 (O-SPE) (aff. index 12.8); clusters 2,4,5 with cat. 3 (C-NHE) (aff. indexes 8.1, 9, and 6.2, respectively); cluster 4 with cat. 2 (NC-HE) (aff. index 5.9); cluster 1 with cat. 1 (C-HE) (aff. index 8.2). When the correlation among different entries was analyzed, very scattered results were retrieved (Figure S1). However, some entries or combinations of them showed some affinities (specificity and fidelity above 0.5) with certain clusters such as _Alternaria alternata_ with cluster 2 (Indval Index = 0.75); _Acrothecium_ sp. and _Penicillium_ sp. with cluster 4 (Indval Index = 0.70 and 0.66, respectively); _Parengyodontium album_ and _Rhinocdiaella_-like with cluster 5 (Indval Index = 0.70 and 0.64); _Actinomucor elegans_, _Penicillium pancosinium_, _Acromoniella__ata__ata__, Alternaria__angutivoidea__, Scolecobsidium anomalum__, Scolecobsidium__lascauxensis_, \begin{table}
