The image depicts the bark of an oak tree covered with two types of fungi: Biscogniauxia atropunctata and a tan resupinate polypore fungus.

Biscogniauxia atropunctata is characterized by its dark brown or black fruiting bodies, which can grow up to 4 cm in diameter. The fungus has a distinctive pattern of small, rounded spots on the surface of the caps, giving it a mottled appearance. It typically grows on dead or dying trees, particularly oak and other hardwoods.

The tan resupinate polypore fungus is a type of bracket fungus that grows on the underside of tree bark. It has a fan-shaped or semicircular cap with a smooth, wavy, or lobed edge. The cap is usually 2-6 cm wide and ranges in color from light brown to dark reddish-brown. The fungus grows in clusters on the bark of dead or dying trees.

Both fungi are saprotrophic, meaning they obtain their nutrients by breaking down organic matter in the environment. They play an important role in decomposing dead plant material and recycling nutrients back into the ecosystem.

The image also shows a close-up view of the oak tree's bark, which is rough and textured with deep grooves and ridges. The bark is likely from a white oak (Quercus alba) or another species of oak that has similar characteristics. – AI vision

🇪🇸 Descripción en español / Spanish Description

Biscogniauxia atropunctata (Hypoxylon atropunctatum) y un hongo poliporo resupinado de color tostado en la corteza de un roble en Hensel Park. College Station, Texas, 2 de diciembre de 2017. La imagen muestra la corteza de un roble cubierta por dos tipos de hongos: Biscogniauxia atropunctata y un hongo poliporo resupinado de color tostado. Biscogniauxia atropunctata se caracteriza por sus cuerpos fructíferos marrones oscuros o negros, que pueden crecer hasta 4 cm de diámetro. El hongo tiene un patrón distintivo de pequeñas manchas redondeadas en la superficie del sombrero, lo que le da un aspecto moteado. Este hongo crece en árboles muertos o moribundos, particularmente robles y otras especies de madera dura. El hongo poliporo resupinado de color tostado es un tipo de hongo con soporte que crece en la parte inferior de la corteza de los árboles. Tiene un sombrero en forma de abanico o semicircular con un borde ondulado, liso o lobulado. El sombrero mide normalmente entre 2-6 cm de ancho y suele tener un color que oscila entre marrón claro y pardo rojizo oscuro. Este hongo crece en grupos en la corteza de los árboles muertos o moribundos. Ambos hongos son saprotrofos, lo que significa que obtienen nutrientes descomponiendo materia orgánica del entorno. Desempeñan un papel importante al descomponer material vegetal muerto y reciclar los nutrientes de nuevo en el ecosistema. La imagen también muestra una vista detallada de la corteza del roble, que es áspera y texturizada con surcos y arrugas profundos. Es probable que se trate de un roble blanco (Quercus alba) u otra especie de roble que presente características similares. – Spanish translation
