Mossy tufts on a lichenious branch 📍Small Dole #iseemoss

A textured tree branch coated in dense green moss and scattered lichens, shown in sharp focus against a softly blurred backdrop of leaves and bright sky.

Loving this moss and lichen ensemble #iseemoss 🔬💚

What happens when you take moss, microscopes and curiosity to a nature festival? At the Storrington White Stork and Nature Festival, Moss Safari had its first proper “field” event. Read the blog: mosssafari.com/2026/05/27/r... #iseemoss #MossSafari #Microscopy #Tardigrades #Nature

Since Mastodon loves moss, you probably enjoy those very mossy rocks at River Waldnaab #mosstodon #microadventure

Spotted this delicate Wood Sorrel tucked in the moss. 🌸 With those heart-shaped leaves and fresh dewdrops, it’s Irish spring magic. Some even say this is the original shamrock! #photography #EastCoastKin #TeamPixel #WoodSorrel #IrishNature #SpringWatch #Macro #Woodland #Wildflowers #Ireland

A detailed macro photograph of a Wood Sorrel flower blooming from a lush, vibrant green mossy bank. The flower has delicate white petals with fine lilac-purple veins and tiny dewdrops clinging to its surface. Surrounding the bloom are several bright green, heart-shaped leaves characteristic of the species. The background is a soft, warm-toned blur of forest brown and amber, creating a shallow depth of field that emphasises the fragile, fresh atmosphere of a damp Irish woodland in spring.

Water drops on sporophytes #moss

A bed of well soaked green moss with thin sporophytes emerging. On the end most capsules have a blob of rain water held in place by surface tension. The rain blobs are extremely clear and act as magnifiers

Mossy masses. Sun-kissed green. 💚🔬 #iseemoss

A close-up of a tree branch thickly carpeted in bright green moss, glowing where sunlight catches its tiny fronds. The background is softly blurred woodland—bare branches, muted foliage—making the sunlit moss the clear focal point.

This is the latest book review of Moss Safari, this time in the Association for Science Education's - School Science Review. Quote 'After reading this book and observing the Big Five for themselves, readers are unlikely to take their environment for granted again.' www.ase.org.uk/resources/sc...

Copy of a snippet of the Association for Science Educations School Science Review Journal book review of Moss Safari: Exploring the Secret Life in Moss by Andrew Chandler‑Grevatt, showing the book cover with bright green moss and illustrations of microscopic organisms such as a tardigrade. Text beside the cover lists publication details, price, and ISBN, and a short description explains that the book introduces five remarkable moss‑dwelling organisms, designed for KS3 and KS4 biology teaching.

Mossy islands on a willow branch 🔬💚 #iseemoss

Close‑up of a willow trunk seen from below, its bark dotted with rounded, cushiony mounds of bright green moss. The soft clumps sit among patches of pale lichen, creating a quilt of textures as the trunk rises toward thin branches and a clear blue sky.

Becoming Moss
I lie on the ground.
I open my mouth.
I suck on a spoon.
I embrace a stone.
A beetle crawls by.
I empty my mind I stuff it with grass I'm green, I repeat.
The sun is a drink the yellowest squash
I can't get enough I can't get enough I can't get enough I can't get enough I can't get enough I can't get enough

Today in the Nagasaki Peace Gardens in Japan Moss is always a symbol of a resilience to me. So very apt in this place for the recovery and hope from the horrors of 1945 🔬💚 #iseemoss

I was in Taipei, Taiwan There was moss Here it is! 🔬💚 #iseemoss

According to my sources, I met this moss in Penang, Malaysia a year ago today 💚🔬 #iseemoss

A close, ground‑level view of bright green moss spreading across a weathered reddish brick. The moss forms a dense, cushiony carpet of tiny leaves, with several thin brown stalks rising above it, each tipped with a small capsule. The brick beneath shows rough texture and patches of pale lichen, giving a sense of age, moisture, and a miniature forest thriving on stone.

Moss collecting water from the air 🔬💚 #iseemoss

A close, intimate view of bright green moss on a dark, rough surface, each slender sporophyte tipped with a clear water droplet. The droplets catch and bend the light, acting like tiny lenses that magnify the moss beneath them. The foreground is crisp and detailed, while the background softens into a blurred wash of greens, giving the whole scene a sense of quiet, miniature abundance.
