Flavopunctelia flaventior
A wander in wintery, snowy woods when most plants lie dormant is an opportunity to focus on the beauty and diversity of lichens! Speckled greenshield or green speckleback (Flavopunctelia flaventior) is a "welcome splash of colour" that "will certainly catch your eye on your winter cross-country ski or snowshoe rambles" (Johnson et al. 1995, Vitt et al. 1988).
It's yellow-green colour, and large, circular patches (thalli) with surface soredia (powdery propagules) and pseudocyphellae (white spots) make it "unlikely to be confused with any other tree-dwelling lichen". It grows on the tree trunks and branches of aspen, poplar, birch, willow and conifers, especially spruce. It's ranked S4 (common) by ACIMS and is widespread across the southern Boreal Forest and northern Parkland; in fact the range map in Vitt et al. (1988) includes the entire province. The Genus name comes from the Latin flavens (yellow) and punctum (a point), referring to the yellowish lobes bearing many tiny pores.

This year, Botany AB will take place on August 2nd-5th, 2013 in the stunning mountains near Lake Louise. There will be a number of hikes including longer and shorter options, and we even may have access to some normally ‘off-trail’ areas! Along the way, there will be sightings of whitebark pine, limber pine, numerous other rare plants, bryophytes and lichens, and of course… incredible mountain views. Preliminary reservations have been made at the reasonably-priced Lake Louise hostel, a beautiful large log building with good amenities including a restaurant, meeting room and a large, comfortable lounge with a great view. We may also make a reservation at the campground, depending on interest. We've booked the meeting room at the hostel Saturday night from 6th-12th and will have a speaker presenting on whitebark pine. A registration form will be posted here soon. If you’d like additional information, please contact Mari Decker.
Bonus Botanizing! There is also an opportunity to extend your trip and enjoy two botany weekends in a row. Botany BC is planning their annual get-together for the weekend after Botany AB: August 8th-11th in the Columbia Mountains near Revelstoke, BC. For costs and more information about this event, check the Botany BC website or contact Elizabeth Easton. The main headquarters for Botany BC will be in the Revelstoke Senior's Centre. There are many options for accommodations nearby (including camping suggestions at the above website), but it is a popular place in the summer, so you will need to book a spot early.
