Abstract: Capitotricha attenuans is reported on twigs of the type substrate Rumex suffruticosus in a subalpine area near the type locality in the Cantabrian Mountains about 175 years after it was distributed as an exsiccatum by M.C. Durieu under the name Peziza bicolor (≡ Capitotricha bicolor). In the 19th century the species was given two different names, Peziza attenuans and Lachnella hispanica, and in the 20th century R.W.G. Dennis referred it to synonymy of C. bicolor. We here transfer its oldest legitimate name to Capitotricha because the species is sufficiently distinct from C. bicolor in having asci arising from croziers and larger ascospores, besides deviating ITS and LSU rDNA data. An epitype is designated based on the recent sample with a sequence

In 1835, the French soldier and botanist Michel Charles Durieu de Maisonneuve (1796-1878) made a journey of botanical exploration throughout the Cantabrian territories of the Iberian Peninsula, focusing particularly on Asturias. What is known about this trip is based on the account written by Gay (1836), whose Spanish translation was published […]
