“…This organization is markedly distinct from the cystidial cytology reported throughout the Agaricomycetes, particularly in ER morphology and the condition of secretory or storage products (Clémençon 1972, 1975, Thielke 1972, Gull and Newsam 1975, Thaler and Gailhofer 1981, Thielke 1983). The cytoplasmic organization characteristic of cystidia from these Suillus species includes a loose endomembrane system, which is more tubular rather than cisternally organized.…”

“…These characters include descriptions of secretory products, wall differentiation, nuclear condition and the differentiation of specific cytoplasmic organelles such as Golgi and ER. The marked degree of ER differentiation among cystidia of species of Agaricomycetes has been stressed by many investigators (Setliff et al 1972, Thielke 1972, Thaler and Gailhofer 1981, Clémençon 2004. Because the number of taxa entered in the Database is small, full delineation of cystidial character states is far from resolved.…”

Cystidia of Suillus americanus and S. granulatus (Boletales) were examined cytochemically and ultrastructurally with cells prepared by freeze substitution. We present the first study showing ultrastructural details and cytological functions of the cystidium to be conserved in two closely related species. The results are presented for inclusion in the AFTOL Structural and Biochemical Database to aid in the application of morphological characters to phylogenetic studies. The cystidia of these Suillus species appear to be united by a series of conserved characters, including specialized secretion mechanisms, smooth tubular endoplasmic reticulum and abundant free ribosomes. The conservation of these subcellular traits among members of this genus suggests that ultrastructural details of cystidia may provide a suite of phylogenetically informative characters. Inclusion of such characters in phylogenetic analyses might resolve or provide support for monophyletic groups at the level of family or genus.

Ultrastructure of the cystidia of Psathyrella aff. nolitangere (Fr.) A. Pearson & Dennis and Psathyrella rhodospora Weaver & Smith (Agaricales) was examined primarily using freeze substitution, with the goal of evaluating whether these cells could provide phylogenetically informative characters with which to study morphological evolution. Within the Agaricales, the diversity of cystidial form coupled with the limited number of studies makes accurate character coding for use in phylogenetic analyses problematic. This study revealed many common cystidial characteristics between the two closely related species examined, including well-formed apical crystals, abundant free ribosomes, and scattered smooth endoplasmic reticulum. Transmission electron microscopy was used for the first time to examine calcium oxalate crystals in cystidia, and demonstrated the formation of a pre-crystalline matrix at the apex of each cell that possibly disrupts the wall as the crystals form. The shared subcellular traits suggest that ultrastructural details of cystidia may provide additional characters for and signal in phylogenetic analyses.
