Germ pore
Encyclopedia
A germ pore is a small pore in the outer wall of a fungal spore
through which the germ tube exits upon germination. It can be apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall.
Apical germ pore is a term applied to mushroom spores which have a pore at one end. Some spores have a hole in the cell wall where the first strand of germinating mycelium
emerges. If the cell wall is divided from one end to the other, this is called a germ slit. Commonly the germ pore is at one end of the mushroom spore and is called an apical pore.
Mushroom genera with apical germ pores include Agrocybe
, Panaeolus
, Psilocybe
, and Pholiota

Spore
In biology, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of many bacteria, plants, algae, fungi and some protozoa. According to scientist Dr...
