Chaetomium ascospores with their characteristic football shape. Chaetomium is a genus of fungi in the Chaetomiaceae family. It is a dematiaceous (dark-walled) mold normally found in soil, air, cellulose and plant debris.
Ascus of Saccharomyces cerevisiae containing a tetrad of four spores. A bitunicate ascus is enclosed in a double wall. This consists of a thin, brittle outer shell and a thick elastic inner wall. When the spores are mature, the shell splits open so that the inner wall can take up water.
Pier Andrea Saccardo (23 April 1845 in Treviso, Treviso – 12 February 1920 in Padua) was an Italian botanist and mycologist.His multi-volume Sylloge Fungorum was one of the first attempts to produce a comprehensive list of identified fungi, using their spore-bearing structures for classification.
A cluster of conidiophore s bearing the spore mass, like a cushion. [363] statismospore A spore that is not forcibly discharged, unlike a ballistospore. Seen in the basidiospores of Gastromycetes. From Gr. statis, immobility. [364] stellate Like a star in form, especially spores. [365] sterigma. pl. sterigmata
In trilete spores, each spore shows three narrow lines radiating from a center pole. [8] This shows that four spores shared a common origin and were initially in contact with each other forming a tetrahedron. [3] A wider aperture in the shape of a groove may be termed a colpus. [8] The number of colpi distinguishes major groups of plants.
Mold is a dangerous library pest because of the damage it causes to the collections. Mold thrives off of paper and books; these objects provide the fungi a source of nutrition, namely the sugar and starches present in the cellulose materials. [6] Mold feeds on cloth, leather, glues, adhesives, cellulose starch and starches in the sizing.
The body of mold consists of a thread-like root that invades the food, a stalk that rises above the food and may not be visible to the naked eye, and spores that form at the end of the stalks ...
A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcefully expelled at full growth. The word basidium literally means "little pedestal". This is the way the ...
