[Occurrence of lomasomes in the basidiospore of Hypholoma fasciculare (Huds. ex Fr.) kummer as revealed by freeze-etching].
Lomasomes were shown to be present in mature basidiospores of Hypholoma fasciculare using the freeze-etching technique. Grooves in the plasmalemma were also generally observed. It is suggested that lomasomes are related to the elaboration of the chitinous spore wall and, in accordance with the views of Campbell, plasmalemma grooves are connected with the melanisation of its outer parts.
