Etymology. Derived from the Latin catenulatus (catenulate, arranged in series of chains) and pilus (hair), referring to the hairs, which are composed of cells that are mostly arranged in chains.
Remarks. C. catenipila is rendered a rather peculiar species by the catenulate shape of the hairs. However, some hairs are articulate-septate and closely resemble hairs of C. magnifica. The new species probably indicates a further link to the genus Pseudombrophila Boud., but the absence of a dark brown or violaceous-purple amorphous pigment in the excipulum, in the hairs and paraphyses, as well as the clavate shape of the paraphyses and the loosening ascospore perispore, confirm the classification in Cheilymenia. The shape of the apothecia makes it easily confused with a species of the section Coprobia. However, as mentioned above, all species of the section Coprobia (Boud.) J. Moravec (1990b) differ in having only hyphoid hairs, and ascospore perispore covered with distinct longitudinal rib-like striation.
Thus, like other genera of Pyronemataceae, Cheilymenia also does not appear to be a sharply delimited genus but, obviously, several phylogenetic links are indicated. As already mentioned, the sect. Obtusipilosae is very close to the genus Pseudoaleuria Lusk, which has been revised and is addressed below.
