Later, perithecia will form around the dead spot, which is another sign of the disease. [1] [2] Symptoms of beech bark disease can be observed in the foliage and on the bole of the tree. Foliage may ...
The trees infected with virus-treated fungus responded immediately and began to heal over their cankers. However, the virus was so efficient at attenuating fungal growth that it prevented the spreading of the virus from an infected fungus growing on one tree to that growing on another tree. Only the virus-treated trees recovered.
Patients present with flat, slightly scaly, red-brown macules on the face, neck, and body, recurring especially around the penial area, or verruca-like papillomatous lesions, seborrheic keratosis-like lesions, and pinkish-red plane papules on the hands, upper and lower extremities, and face.

There's a tree in your backyard that produces spiked round balls, and you have no idea what it is. We can help you identify it, and explain the purpose of those odd seed pods it drops.
Wildlife and people harvest most of them; those remaining produce seedling trees readily. The wood is hard, heavy, strong, and very flexible, making it a favored wood for tool handles. A specimen tree has been reported in Missouri with 117 cm (46 in) diameter at breast height, 36.9 m (121 ft 1 in) tall, and a spread of 22.6 m (74 ft 2 in).
It is a small to medium-sized deciduous tree growing to 20 m tall, with a spreading crown. The bark is smooth and thin, and bleeds latex if cut. The leaves are alternate, simple, 4.5–25 cm long and 3.5–22 cm broad, heart-shaped or with three shallow, maple -like lobes, green above and below, red conspicuous glands at the base of the leaf ...
The fruit is a nut sometimes called "Turkish nuts" about 1–2 cm long, surrounded by a thick, softly spiny and bristly involucre (husk) 3 cm diameter, [1] which encloses all but the tip of the nut; the nuts are borne in tight clusters of 3–8 together, with the involucres fused at the base.
