A cryptic species that can be reliably distinguished from T. subuliformis only using molecular methods. The only Czech record of the thamnolic-acid chemotype typical of T. vermicularis comes from the Hrubý Jeseník Mountains, Mt Keprník (Grünwaldová 1970), but the original population is most likely extinct. Therefore, the occurrence of T. vermicularis sensu stricto in the Czech Republic can neither be confirmed nor definitively excluded, as T. subuliformis also produces thamnolic acid (Onut-Brännström et al. 2018).
