Description:—Pileus 6–11 mm wide × 4–7 mm long, conchate, digitate; sessile or laterally stipitate ( Figure 4A View FIGURE 4 ); when stipe is present, a strigose zone is observed near the basal area; rigid consistency; pellicle 170 to 174 μm thickness;
grayish white (A 30 M 10 C 20) to light brown (N 30 A 20 M 00); context 315 to 320 μm thick ( Figure 4B View FIGURE 4 ). Hymenium with gills 231 to 299 μm in length, tightly rolled; abhymenial hairs 4 μm diam., hyaline and smooth, apexes slightly wavy or spiraled ( Figure 4C, D View FIGURE 4 ); spores 4.7–5.4 × 2–2.6 μm, hyaline, ellipticals ( Figure 4E View FIGURE 4 ).
Habitat and distribution:—Gregarious in small groups, saprotrophic. This species has been reported on wood of Acacia sp. , Persea americana , Eucalyptus sp. ( Olivo-Aranda & Herrera 1994), Hevea brasiliensis , and Mangifera indica ( Farr & Rossman 2017) . In the present study, it was mainly found in medium-height rainforest in Macuspana, Tabasco. In Mexico, it has been reported in the northern and central regions of the country in the states of Colima, Durango, Michoacán, Jalisco, Nuevo León, Nayarit, Morelos, and the State of Mexico and in the southeastern states of Veracruz, Guerrero, Chiapas, Yucatán, and Quintana Roo ( Olivo-Aranda & Herrera 1994). Worldwide, it is distributed throughout the northern United States, Nicaragua, Cuba, Paris ( Linder 1933), and Argentina ( Robledo et al. 2014) .
Examined material:— Mexico. Tabasco: Macuspana, Parque Estatal Agua Blanca , elev. 100 m, GPS 17 °, 52’ N, 92° 29’ W, 25 March 2012, Gómez-García 250 ; 26 March 2012, Mondragón-Sánchez 106; 05 November 2018, Carreño-Ruiz 708 ( UJAT Herbarium) .
Notes:—This species can be confused with S. leprieurii D.H.L. American Journal of Botany (1933: 561). However, at the macroscopic level, S. umbrinum has a pileus of light brown to light gray color. At the micromorphological level, it has elliptical hyaline spores and smooth abhymenial hairs with wavy endings. In contrast, S. leprieurii has a pileus of dark brown to bright golden brown color, cylindrical yellowish brown or light brown spores and abhymenial hairs light brown with granules or crystals along the apical portion ( Linder 1933, Robledo et al. 2014).
