Stratiolaelaps scimitus and the similar species, S. aculiefer are soil-dwelling, predatory mites. Stratiolaelaps mites feed on fungus gnats, springtails, thrips pupae, and other small insects in the soil. The mite is 0.5 mm (1 ⁄ 50 in) long and light-brown in color. It inhabits the top 1 ⁄ 2 inch (13 mm) layer of soil. Both nymphs and ...
Colonies of Madurella grisea are slow growing, dark, leathery, and folded with radial grooves and with a light brown to greyish surface mycelium. With age, colonies become dark- to reddish-brown and acquire a brownish-black reverse.
The fungus can infect seedlings and typically colonizes under the bark of the trees. [1] Since the fungus infects under the bark, the signs of the pathogen aren't visible until the bark sheds off in response to the physical pressure imposed by the growthing pathogen; this typically happens in the transition between spring and summer.

Wood decay caused by Serpula lacrymans (called true dry rot, a type of brown-rot). Fomes fomentarius is a stem decay plant pathogen Dry rot and water damage. A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot.
The blight initially presents as dark or light brown spots or lesions on leaves. The leaves typically turn brown or straw color, then fall off. [10] The stems develop dark brown or black lesions. [11] The disease is often fatal to young plants.
Reddish lesions at first then enlarges and becomes white to light brown in the centre. Circular and varying in size. Can appear concentric with red margins. Leaf spot on most cereals and grasses, field crops, vegetables, ornamentals, and trees. Myrothecium roridum: Target-like spots with light brown centres and dark circumference on Gardenia ...
Infected areas are clearly delineated and light brown, and soft decaying tissue can be easily "scooped" out of the surrounding healthy tissue., [4] [1] Spore masses later appear on the surfaces of infected fruit, initially appearing as white mycelium, then turning blue to blue-green in color as the asexual spores mature.

Peziza phyllogena, commonly known as the common brown cup or the pig-ear cup, is a species of fungus in the family Pezizaceae. A saprobic species, the fungus produces brownish, cup-shaped fruit bodies that grow singly or in clusters on either soil or well-rotted wood. It is found in Europe, North America, and Iceland, where it fruits in the spring.
