  1. What a beautiful gems! This little corner as a whole is amazing. Posted 6 years ago
    1. I've been documenting with specimens and photos the plants, animals, fungi etc on my property for about 25 years. There's always something new. Even when I thought I'd found all the native vascular plants that could be here I found three more species last spring: Solidago flexicaulis, Viola selkirkii, and Polygonatum pubescens. hope to get some good photos of these in May and June. My moth list has grown from just 13 species as of 2016 to at least 400 (some I'm not 100% sure of yet). I added a new springtail (Folsomia candida) last year when I was cleaning out the sump pump well. Posted 6 years ago
      1. That is quite a history, Gary. Hats off to naturalists like you. I'm seeing a handful of people documenting anything they can get their hands on, season after season, in their geographic circle. The sets this produces over time is of incredible value. It's like a long running scientific survey. Not only documenting biodiversity, it's also educational and plain fun. Yet I don't think we have any users going at it as long as you did :)

        Mothing, I can only agree, is and endless source of fun and biodiversity. I wish I had discovered this discipline earlier, but it's never too late. The area I live in is not great for mothing, so I'm not a steady contributor. Where I can, we try to bring the idea on our remote travels. Last year was the first time we did so. Moths are the 2nd most numerous category documented here at JD, after birds. We documented about 1,500...out of 160,000 :)

        Needless to say, don't hold back sharing your archive here.

  2. It is fun for sure. And I learn a lot.

    I came to mothing late also and am amazed at the species diversity here. It isn't like the tropics but they weren't under glaciers for the past 500,000 years or so!

    Once the seasonal glacier recedes (what some people call winter) I'll be out in the woods again. I've got some contracts that will be taking me to some different places in Minnesota so more photos of different things.

Byssonectria terrestris is a species of fungi in the Pyronemataceae family.

Similar to Byssonectria fusispora, but with colonies that tend to be more aggregated, sometimes with a well-developed pale subiculum. Ascomata are often slightly paler, paraphyses have curved rather than straight tips and ascospores are slightly smaller and not or hardly apiculate. Ascospores measure 20.5-23 (mean 21.8) x 8.4-9.1 (mean 8.8) µm in water, 18.2-20.7 (mean 19.6) x 6.4-7.5 (mean 7.1) µm in lactic.. more
