lichens

The stone stairway was covered with lichen.

那石级长满了衣。

Fragments of the thallus containing both phycobiont and mycobiont cells may also grow into new lichens, a from of asexual reproduction.

衣的碎裂片中，如含有藻类和真菌共时，也可长成独立植，这是一种无性的殖式。

The lichen is a typical example of the intergrowth among the microorganism, it is fungi, blue bacterium or homobium of the alga.

衣就是微物间共的典型例子，它是真菌和蓝细菌或藻类的共。

Reproduction in lichens may be asexual by soredia (algal cells enclosed by fungal hyphae) or by sexual fungal spores, which can survive only if some algal cells are also present.

衣可以利用粉芽（真菌菌丝包裹藻类细胞）进行无性殖或利用真菌孢子进行有性殖。
