Only eight taxa of Chaetotyphula have been described worldwide. In 2001, Flegel and Ruksawong introduced the genus Chaetotyphula to Thailand; however, the specimen of Chaetotyphula has not yet been formally classified as a species. The present research postulates a novel record of Chaetotyphula columbiana from Thailand. The specimen was discovered amidst leaf litter in the dipterocarp forest located in Khao Yai National Park in 1999. This mushroom is small, 10–20 mm long, 1-2 mm wide, typhuloid in shape, white with a translucent appearance, smooth on the head, but velvety from the stalk surface to the basal of the basidiocaps. The basidiocarps were raised directly from the leaf litter. The aforementioned species exhibits a notable dichotomy in the morphology of its metuloid dermato-cystidia, which can be classified into two distinct categories: encrusted and non-encrusted, yet diverticulate.
