Posts Tagged ‘Bumpy Rim Lichen’

So many more of the smaller things become visible when the leaves fall, like the tongue gall on these  alder cones (strobiles.) These long, tongue like galls are caused by a fungus called Taphrina alni. The fungus chemically deforms part of the ovarian tissue of the developing strobile and causes long, strap shaped galls called languets to grow from them. These galls, like most galls, don’t seem to bring any harm to their host.  I wish I knew how they benefit from growing in such unusual forms.

I didn’t know if this ladybug was dead or alive or maybe frozen, but it wasn’t moving. And where were its spots? The answer is, it doesn’t have spots because it isn’t our native ladybug; it’s a female multicolored Asian ladybug. From what I’ve read it is highly variable in color and was purposely introduced by the U.S. Department of Agriculture as a biological control agent. It is a tree bark dwelling beetle that consumes large amounts of aphids and scale, both of which do large amounts of damage to crops. They’re slightly larger than our native beetles and can drive homeowners crazy by collecting on windowsills, in attics, and even indoors in the spring. They can release a foul smelling defensive chemical which some are said to be allergic to.

We’ve had more snow in parts of the state. It’s very odd to leave my yard at my house that has no snow in it and drive to work where I see snow like this. It’s only a distance of about 25 miles, but it’s enough of an elevation change to cause cooler temperatures. It really drives home what a difference just a few degrees can make.

I thought this beech tree was beautiful, with its Christmas ornament like leaves.

And what was that poking up out of the snow?

It was a fallen limb which was covered by what I think was orange crust fungus (Stereum complicatum,) which is very common here. I see large fallen limbs almost completely covered by it. Though this isn’t a very good shot of it the color is so bright sometimes it’s like a beacon in the snowy landscape. The complicatum part of its scientific name means “folded back on itself”  and that is often just what it does.

Amber jelly fungus (Exidia recisa) grew on the same branch the orange crust fungus grew on. I like holding these up so the light can shine through them because sometimes they look like stained glass. Being in the snow meant these examples had absorbed plenty of water so they were pliable and rubbery, like your ear lobe. I see this fungus everywhere, especially on fallen oak limbs but also on alder and poplar as well.

I decided to visit a grove of witch hazels (Hamamelis virginiana) that I know of to see if they were still blooming. Blooming or not, they were beautiful with all of the newly fallen snow decorating them.

And they were still blooming, even in the snow. This tells me that it must be the air temperature that coaxes them into bloom because it was about 40 degrees this day.

I know it’s far too early to be looking at buds for signs of spring but red elderberry (Sambucus racemosa) buds are so pretty I couldn’t help myself. I’ve known people who thought that buds grew in spring when it warmed up, but most buds actually form in the fall and wait  for warm weather to swell up and break and form leaves and / or flowers. These buds should break in mid-May, if it’s warm enough.

I’ve seen some unusual lichens lately, like this grayish white example which had the same color apothecia (fruiting bodies) as the body (Thallus.)  This made them hard to see and I only saw them by accident when I got close to look at something else.

I wish I knew what caused the colors in a lichen. As far as we know they don’t use color to attract insects but many of them are brightly colored nevertheless. I have seen teeth marks in lichens so I’m fairly sure squirrels eat them and I know for sure that reindeer eat them, but I don’t know if this helps them spread or not. I also don’t know the identity of this lichen. I haven’t been able to find it in any of my lichen books or online.

Here’s another unusual lichen; actually two lichens separated by the nearly horizontal crack between them. The lichen on top might be a bumpy rim lichen (Lecanora hybocarpa,) which gets its name from its bumpy body (Thallus) and the rims around its apothecia.  The lichen below the crack has me baffled. It has a fringe around its perimeter that makes it look like a maple dust lichen but I can’t find any reference to apothecia on a maple dust lichen. It’s another mystery to add to the thousands of others I’ve collected.

Here is a true maple dust lichen (Lecanora thysanophora.) Note the white fringe around its outer edge, much like the lichen in the previous photo.  But unlike the previous lichen it has no visible fruiting bodies.

If you have ever tasted gin then you’ve tasted juniper berries, because that’s where gin’s flavor comes from. The unripe green berries are used for gin and the ripe, deep purple black berries seen here are ground to be used as a spice for game like deer and bear. The berries are actually fleshy seed cones and they appear blue because of a waxy coating that reflects the light in such a way as to make them appear blue. The first recorded usage of juniper berries appears on an Egyptian papyrus from 1500 BC. Egyptians used the fruit of junipers medicinally and Native Americans used them both as food and medicine. Stomach disorders, infections and arthritis were among the ailments treated.

Gray, furry willow pine cone galls appear on the very tips of willow branches, because that’s where a midge called Rabdophaga strobiloides lays its egg. Once the eggs hatch the larvae burrow into the branch tip and the willow reacts by forming a gall around them. These galls are about as big as the tip of your thumb and do not harm the plant.

A woodpecker, chickadee, or other bird started pecking at this goldenrod gall to get at the gall fly larva (Eurosta solidaginis) that is growing inside the gall. These galls have thick walls that discourage parasitic wasps like Eurytoma gigantean from laying its eggs inside the larval chamber. If successful the wasp larva quickly eat the gall fly larva. If the bird is successful then everything inside will be eaten.

We’re certainly having some beautiful sunrises lately, probably because of the low cloud deck we seem to have almost every morning.

And those low clouds can hide things, including mountains. Off to the left in this photo is the huge bulk of Mount Monadnock behind the clouds. It’s too bad it was hidden; the bright morning sunshine on its snowy flanks tells me it probably would have been a beautiful scene.

Seeing, in the finest and broadest sense, means using your senses, your intellect, and your emotions. It means encountering your subject matter with your whole being. It means looking beyond the labels of things and discovering the remarkable world around you. ~Freeman Patterson
