One of the three species in the genus Rhodactina, which was described from a community forest in Chiang Mai Provine, northern Thailand, in 2006. This species is differentiated from the other species by its basidiospores bearing (7)8–9(10) longitudinal ridges, without a markedly prominent hilar appendage.
Why suggested for a Global Red List Assessment?
In 2006, Rhodactina incarnata was described from a community forest, Chiang Mai Province, Thailand, based on a single collection. After that, the species has not been found and reported again.
Population and Trends
Only a single collection containing one basidioma, was found in the community forest in Chiang Mai Province, Thailand. It has never been found again in the forest and other forests. The population and current trend remaining uncertain.
Population Trend: Uncertain
Habitat and Ecology
The species was only found once on sandy soil, in dry dipterocarp forest dominated by Dipterocaparus tuberculatus, D. obtusifolius, Shorea siamensis, S. obtusa with scattered of a few Eucalyptus sp, elevation about 350-400m.
Subtropical/Tropical Dry Forest
The type locality where the species was found, is one of the places where a number of local people go for collecting mushrooms especially the Astraeus sp. As the Astreus form its basidiomata in the sub-underground, (similar to R. incarnata) to find the Astraeus the soil surface around the host trees is terribly dug and removed. Therefore, this might be one of the human activities that disturbing R. incarnata habitat.
