Importance and distribution
Racoleus comprises only one species known on trunk of a large tree in dense shade in a rainforest, overgrowing Dichosporidium brunnthaleri (Roccellaceae) in Africa (Ivory Coast). It grows on whitish crustose lichens such as Dichosporidium brunnthaleri, D. nigrocinctum, Pyrgillus indicus. Racoleus overgrows the crustose lichens and has no close interaction with them and is easily detached. Racoleus is considered as a sampling artefact, because it is more easily noticeable alongside a white background (Hawksworth et al. 2011).
