The Calicioids of Forillon National Park, Quebec, Canada.

The calicioid lichens are lichenized fungi with ephemeral asci that break down before the spores have matured to form a mazaedium. This group of lichens is often referred to as ‘pin or stubble lichens’ due to their minute, though not exclusively, hair-like fruiting bodies. Non-lichenized fungi that share this distinctive form (calicioid fungi) are traditionally treated with their lichenized counterparts, despite lacking a mazaedium, and the two groups are collectively known as calicioids. The distribution of calicioids is poorly understood in many areas of North America. For example, there were no previously known collections from Forillon National Park in Quebec, Canada. Therefore, we conducted a survey of the calicioid species in this unexplored area and discovered 30 species in 9 genera. One species, Chaenothecopsis oregana, is new to eastern North America; two species, Calicium denigratum and Sclerophora coniophaea, are new to Quebec; and one species, Sclerophora peronella, is listed under Schedule 1 of the Canadian Species at Risk Act. We summarized our results in an annotated checklist and developed a key to the calicioid species of Forillon National Park.
