Description:
Diagnosis: Gasterocarp globose to pyriform, white with a silky sheen drab gray tinges, bruising brownish gray to dark brown. Gleba enclosed, loculose, vinaceous at first, then soon pale cinnamon to avellaneous, with empty locules. Stipe absent but with a sterile basal pad. Spores reddish purple, longitudinally costate, with 6-10 ribs, dextrinoid. Peridial pellis repent, with fine to coarse encrustations. Clamp connections absent.
Registration number: MB 27635
Type species: Rhodactina himalayensis Pegler & Young, Opera Botanica 100: 201. 1989.
Ectomycorrhizae: In forest of Dipterocarpaceae (Shorea).
Distribution: India, Thailand.
Commentary: Molecular inference from sequences of the atp6 gene placed Rhodactina in the Boletaceae. See Yang et al., 2006. Mycotaxon 96: 133-140. Further work by Vadthanarat et al (2018) using atp6, tef1, and rpb2 infer strong support for placement in subfam. Leccinoideae.
Number of species: 3 - R. himalayensis, R. incarnata, R. rostratispora.
