8. Common inkcap
Gray mushrooms are a common sight in many wooded areas, and one variety that stands out is the Common inkcap. Scientifically known as Coprinopsis atramentaria, this mushroom species belongs to the family Psathyrellaceae.
True to its name, the Common inkcap boasts a distinctive gray coloration on its cap and stem. While it may appear unassuming at first glance, this mushroom holds some fascinating qualities.
One striking characteristic of the common inkcap is its ability to rapidly dissolve into an inky black liquid as it matures. This process is known as deliquescence and occurs when the mushroom produces spores.
As the cap expands and ages, it begins to liquefy from the edges inward, transforming into an inky substance that drips down onto the ground below. These grey mushrooms are edible but avoid alcohol when eating them.
9. Mica Cap (Coprinellus micaceus)
Coprinellus micaceus, also called the mica cap or shiny cap mushroom, is a species of fungus in the family Psathyrellaceae. These mushrooms are characterized by their small to medium size and distinctive appearance.
The caps of Coprinellus micaceus are convex when young but flatten out as they mature, reaching a diameter of 0.5-1 inch. They have a smooth texture and are typically gray or brown in color.
One striking feature of Coprinellus micaceus is the presence of tiny reflective particles on its surface, giving it a shimmering or glistening appearance hence its common name “shiny cap.”
This unique attribute is caused by the accumulation of crystalline substances known as cystidia on the mushroom’s cap.
Another interesting aspect of this species is its rapid growth and decomposition process. The fruit bodies emerge quickly after rainfall and can double in size within just a few days.
Mica caps grow gregariously and are edible.
10. Gem-studded puffball (Lycoperdon perlatum)
Lycoperdon perlatum, commonly known as the gem-studded puffball or warted puffball, is a unique fungus that belongs to the family Agaricaceae. It is characterized by its unique appearance and distinctive features.
The fruiting body starts off round and smooth but gradually becomes covered in spiny projections or warts as it matures. These warts are often brownish or grayish in color and give the mushroom a striking aesthetic appeal.
When it comes to spore dispersal, this puffball releases clouds of powdery brown spores through a small opening at the top, called an ostiole. This process occurs when the outer layer of the mushroom ruptures due to changes in internal pressure caused by raindrops or physical disturbances
As these tiny spores are dispersed into the air, they can be carried over long distances by wind currents, allowing for effective reproduction and colonization.
The gem-studded puffball can typically be found growing on forest floors or open grasslands from late summer to autumn.
They are generally considered edible when young and still white inside.
11. Field’s Bird Nest (cyathus olla)
Field’s bird nests are a type of unique gray fungi found all over Europe and North America. What sets this mushroom apart from others is its unique reproductive strategy.
Instead of producing spores directly on its surface like most mushrooms, this bird nest species has evolved small cup-shaped structures resembling miniature bird nests. These tiny cups contain even tinier eggs – the spore capsules that will eventually be dispersed by passing raindrops or animals brushing against the fungus.
The bird’s nest fungi serve as nature’s clever tricksters, luring insects and other small creatures to their nests with a tantalizing scent reminiscent of decaying organic matter. Once inside, these unwitting visitors become potential carriers for the fungal spores, as they inadvertently pick up and transport them to new locations.
This complex relationship between the bird’s nest fungi and their unsuspecting guests showcases nature’s ingenuity in coevolutionary adaptations.
12. Gray Shag (Coprinopsis cinerea)
Coprinopsis cinerea, colloquial name gray shag, is a unique species that offers both beauty and mystery. Found in abundance throughout North America and Europe, these mushrooms are often seen emerging from decaying organic matter such as rotting logs or compost heaps.
With their distinct gray cap and slender white stem, they might appear like any other common mushroom at first glance. However, their true fascination lies in their biology and life cycle.
One fascinating aspect of Coprinopsis cinerea is its rapid growth rate. These mushrooms can emerge overnight and reach maturity within hours.
This process is so swift that you could almost watch it happen before your eyes! It starts with small button-like structures that expand rapidly into larger buttons before unfurling their cap to release spores – an essential mechanism for reproduction and dispersion.
Furthermore, the lifecycle of Coprinopsis cinerea has an intriguing twist known as autodigestion or self-digestion.
As the gills beneath its cap mature in preparation for releasing spores, they gradually break down into a black liquid containing enzymes that aid in spore dispersal. This highly efficient process ensures maximum chances of success for this remarkable species.
13. Mossy Maze Polypore
The mossy maze polypore is a fascinating species that often goes unnoticed in our forests. With its striking grey color and intricate maze-like pattern on its cap, it adds a touch of mystery to any woodland setting.
This unique fungus can be found growing sugar maples and some species of birch trees, causing rot and decay.
What makes the mossy maze polypore truly intriguing is its survival strategy. Unlike many other mushrooms that rely on spores for reproduction, this species can also reproduce asexually through fragmentation of its mycelium network.
As portions of the fungus break off and spread throughout the forest floor, new colonies of grey mushrooms can quickly form. This adaptive ability ensures their presence in various habitats and contributes to their reputation as one of nature’s resilient organisms.
14. Clouded Agaric (clitocybe nebularis)
Clitocybe nebularis, also known as the Clouded Funnel or clouded agaric, is a captivating species of mushroom found in deciduous forests.
