Ceratiomyxa fruticulosa var poroides

Fruitbodies of the variety porioides   as shown in picture above are dome-shaped, white, honeycombed, and up to a centimetre across.    Fruitbodies of the variety fruticulosa form tiny white columns only a few millimetres tall. Under a hand lens, they have a fuzzy appearance due to production of spores on the surface. The fruitbodies are very delicate and, as for many slime moulds, can be obliterated by the touch of a finger.  Widespread and common, this slime mould fruits in scattered clusters over well-rotted logs. Both varieties are common after prolonged rainy periods.
