Pereira [136,947,626,653] Sordariomycetes Xylariaceae Cladosporium Fungi Xylariales 18 19 Ascomycota species brigadeirensis sp. nov.   MycoBank: MB824726   Systematic position: Fungi, Ascomycota, Pezizomycotina, Dothideomycetes, Dothideomycetidae, Cladosporiales, Cladosporiaceae   Etymology:—Name refers to the place from where the species was collected, “Parque Estadual da Serra do Brigadeiro”.   Colonieson PDA attaining 57 mmdiam after 14 days, at 25 ºC, under near-ultraviolet light, smoke grey, greenish glaucous, velvety, furrowed; reverse dark bluish-green. Colonies on MEA attaining 53 mmdiam, grey olivaceous, white at the margin, pale olivaceous grey to greenish glaucous aerial mycelium; reverse greenish-black. Colonies on OA attaining 58 mmdiam, grey olivaceous, glaucous grey to greenish glaucous at the margin; reverse greenish-grey. Colonies on SNA attaining 54 mmdiam, olivaceous to olivaceous buff; reverse similar to surface. Myceliumdiffuse, branched, hypha ranging from very thin to swollen 1.39–4.92 µm wide, septate, sometimes swollen and slightly constricted at the septum, subhyaline, pale brown to brown, irregularly rough-walled to verrucose. Conidiophoressolitary, macronematous, 25.07–222.22 × 2.51–4.80 µm, arising lateral or occasionally terminal from hypha, erect or flexuous, cylindrical-oblong, sometimes attenuated towards the apex, occasionally filiform, pale brown to brown, sometimes subhyaline, commonly 2–12 septate, some reaching a larger number, some branched several times towards the apex, occasionally geniculate, irregularly rough-walled, micronematous, laterally, 14.0–22.58 × 1.90–3.11, pale brown to subhyaline, cylindrical or cylindrical attenuated to apex 1–2 apical loci. Conidiogenous cellsintegrated, mostly terminal, sometimes intercalary, some geniculate-sinuous with secondary ramoconidia arising from small lateral shoulders, occasionally continuing growth to up, cylindrical or cylindrical attenuated to apex, 9.32–25.16 × 1.73–3.65 µm, brown, sometimes subhyaline 1–6 loci at apex, rarely arranged like a garland round about the stalk, with many loci crowed the intercalary cell, conidiogenous loci non-protuberant or only slightly so, often thickened and refractive or darkened. Ramoconidiaabsent. Secondary ramoconidiacylindrical, ellipsoid, rarely obovoid, three to various distal hila, 4.48–13.52 × 2.21–3.51 µm, aseptate, pale brown to subhyaline. C onidianumerous form clustersin the cell that originated them, short sometimes long chains, ellipsoid, globose to subglobose, aseptate, subhyaline to dark brown, 3.02–6.81 × 2.18–3.60 µm, hilum inconspicuous, terminal conidia ellipsoid, globose to subglobose, 3.01–4.50 × 2.10–4.42 µm. Occurrence of microcyclic conidiogenesis.   Type:—  Brazil. Minas Gerais: Araponga, at “ Parque Estadual Serra do Brigadeiro”, isolated from decayed leaf of  Chusquea urelytra(Poaceae),  March 15, 2016( holotype VIC 44238, ex-type culture COAD 2257).  GenBank: MT373127( ACT), MT680206( TEF1-α), MZ318435(rDNA-ITS)   Notes:—  Cladosporium brigadeirensisclusters as a sister clade to  C. puris,but is morphologically distinguishable.  Cladosporium purishas secondary ramoconidia with two to three hila, while  C. brigadeirensishas three to various hila crowding the apex of the conidiophores.The new species sometimes forms a prolongation of the secondary ramoconidia at the apex, giving rise to stems that resemble formations of new conidiophores. Its swollen hyphae can also be much wider (up to 4.92 µm) compared to  C. puris(up to 2 µ) ( Freitas et al.2021). The microcyclic conidiogenesis that occurs in  C. brigadeirensishas not been reported in  C. Puris. 3897141302 2016-03-15 VIC Brazil Parque Estadual Serra do Brigadeiro Araponga 18 19 VIC 44238 1 Minas Gerais holotype
