Note the gracious preference for regional Michele Piercey-Normore accuracy over jingoistic and vulgar self-promotion: readers were offered a name reflecting our province, Helen Spencer where it was discovered, but opted for a name Marian Wissink meaning laurentian, to reflect its presence elsewhere in the St Lawrence Basin.

OMPHALINA Message from the Editor Happy 98th anniversary of Estonian independence! Here we are, almost two years to the day when we published our morel issue, letting you know that we have three morel species in NL, two of them apparently undescribed. Now, two years later, they are formally described, with names you and everybody else can use. Named by readers of OMPHALINA ! Come May, you should be ready, so go out looking and see whether you can identify them. Everybody eats, so many must also cook, but few send in recipes. Why is that? Thanks to Robin McGrath for her steadfastness in this regard and an appeal to the rest of the cooks—please share your creations or favourites. Boletus betulicola? You may not know the species, but if you were at the last Foray, you ate it. And from comments, apparently it is a species worth knowing. Should you have a bit of scientific curiosity, there is a good project in there to study, figure out. If you have some detective spirit in you, maybe we can find a partner to help with the technical aspect. The same goes for Xeromphalina enigmatica. No more X. campanella. Yes, read the latest: X. enigmatica is the name of our version of the orange pinwheel mushroom. You will learn that enigmatica also has a mystery to be solved: very possibly there are more species than we are prepared to recognize now. If you are curious, have the resources to collect a week or two in a few places on the mainland as well as here, we might be able to find a partner with the high tech toys to finish a good project. Just call. Happy mushrooming! andrus 2 OMPHALINA 8 7 Update: 6 5 4 Our 3 2 morels 1 0 are ecogaia named! eselensis mari3ma enelensis eohespera la1ren3ana sophis3cata cosmopolita transoceana Andrus Voitk, Kerry O’Donnell, Michael tricon3nentalis semperaeadem Beug, Michael Burzynski, Henry Mann Photo: Claudia Hanel Preliminary investigations revealed Laurentian to indicate that its distri- vol. 5, issue 2 for examples of how that at least three morel species bution is limited to the St Lawrence dramatically location, climate or grow in Newfoundland and Labra- River Basin.5 Formal description of maturity influence these characters. dor: Morchella importuna, the mulch these two species has now been ef- Because averages seem reliable but morel, and two undescribed species, fectively published, and we are glad individuals vary (for example, see Mel-19 and Mel-36.1 M. importuna is to report that the names favoured the fruiting time graph, Figure 4), do known from Europe, Asia and North by our readers were used.7 not focus on a single specimen, but 2,3 America.
