Pleurotus pulmonarius (Fr.) Quél., Mém. Soc. Émul. Montbéliard, Sér. 2 5:11 (1872)

Remarks: This species is very similar to Pleurotus ostreatus, but the generally smaller, paler and short-stipitate basidiomes differentiate P. pulmonarius from P. ostreatus (Stamets 2011) .Yet, Menolli Jr. et al. (2014) emphasize that morphological and ecological data are not the best choice for the recognition of species in the genus. P. pulmonarius is an edible species, known to have several nutritional and nutraceutical attributes (Khan & Tania 2012) along with a great cultural importance too (Ruán-Soto et al. 2006). Our study provides the first two occurrences of the genus Pleurotus for the state of Tocantins.

Ecology & Distribution: Growing on deciduous wood. Temperate to subtropical regions of the world (Menolli Jr. et al. 2014). In Brazil, it is recorded for the states of Paraná, Rio Grande do Sul, São Paulo (Menolli Jr. et al. 2014), and for the Cerrado region of Mato Grosso do Sul (Bononi et al. 2017). This is the first record for Tocantins.
