Summary
[edit]DescriptionEstrella de tierra - Astraeus hygrometricus (15111581164).jpg |
Español: Se mantiene durante meses, de manera que es fácil encontrarla. En tiempo seco, el exoperidio se contrae, envuelve y tapa el endoperidio.
Por el contrario, en tiempo húmedo y favorable a la dispersión de las esporas, el exoperidio se hidrata, abre y aplana o hasta se incurva hacia el exterior levantando la seta. En este estado hidratado, la estrella de tierra higrométrica puede moverse como el andar de un cangrejo en la arena o ser arrastrada por el viento Se diferencia de la verdadera estrella de tierra (Geastrum ) por la rugosidad de la superficie del exoperidio, por su endoperidio alzado y rasgado irregularmente y por su consistencia variable según la humedad ambiental. Zona , bosque de pinos y robles |
