Description
Trichaptum sprucei (Berk.) Rajchenb. & Bianchin., Mycol. Res. 96(11):957 (1992)
Remarks: This species is characterized by effused-reflexed to resupinate basidiomes with a violaceusbrown growing margin (turning brown with age), hymenophore varying from poroid to irpicoid, apically incrusted hymenial cystidia and the presence of thick-walled, globose to pyriform, brown chlamydospores (Gibertoni et al. 2011; Herrera Figueroa & Decock 2007; Rajchenberg & Bianchinotti 1992). These abundant and large chlamydospores (8.3-14.4 x 7.9-11.7 µm), commonly mistaken for spores, led to the reclassification of T. sprucei into the Amazonian tropical genus Phaeodaedalea (Fidalgo 1961), which was latter synonymized with Trichaptum Murril (Herrera Figueroa & Decock 2007). Currently, some authors consider it a synonymy of Trametes incerta (Curr.) Cooke, a species originally described in Myanmar. Even so, molecular data shows that these species form two distinct clades, with T. sprucei s.s. probably having a distribution restricted to the Neotropics, while Trametes incerta has an Asian distribution (Herrera Figueroa & Decock 2007). So, we decided to keep the name Trichaptum sprucei due to its Neotropical holotype, the presence of cystidia (very similar to those found in other species of the genus) and molecular data corroborating its circumscription in Trichaptum. Still, we endorse the need for further studies in this clade, along with all Neotropical specimens identified as Asian Trichaptum species.
Ecology & Distribution: Growing on deciduous wood. Neotropical, with few records from Asia and Africa (Gilbertoni et al. 2011). In Brazil, it is recorded from Amazonas, Bahia, Mato Grosso, Pará, Paraíba, Paraná, Rio Grande do Sul, Rondônia and São Paulo (Flora do Brasil 2020 as Trametes incerta (Curr.) Cooke. New record for the state of Goiás.
Specimen Examined: BRAZIL, GOIÁS,Alto Paraíso de Goiás, Raizama, 14°12’08.9” S, 47°50’14.4” W, 17.IX.2018, M. Palacio 335 (ICN202052).
