The fine structure and selected cytochemistry of ungerminated basidiospores of Pluteus

The fine structure and selected cytochemistry of ungerminated basidiospores of Pluteus

Journal of the Pennsylvania Academy of Science 70(1): 15-21

The fine structure of the basidiospores of Pluteus cervinus is described using TEM and light microscopy. The basidiospore wall is composed of two distinct and continuous layers. No surface ornamentation or germ pore is present. The protoplasm is surrounded by a typical membrane which lacks distinct invaginations. Basidiospores contain much stored lipid which is centrally located. Basidiospores are uninucleate with the nucleus closely appressed to the cell membrane located at the base of the basidiospore near the hilar appendage. Mitochondria are present with few, well-delineated plate-like cristae. Endoplasmic reticulum is scant. Ribosomes occur regularly attached to the ER and outer mitochondrial membrane and are also densely packed throughout the cytoplasm. Variously sized, single membrane-bound vacuoles containing an electron dense material are present and exhibit acid phosphatase activity. Assays of malate synthase, a marker enzyme of the glyoxylate cycle, are positive, suggesting that microbody-like organelles are probably glyoxysomes.
