Phialide - Wikipedia
The phialide (/ ˈfaɪəlaɪd / FY-ə-lyde; Greek: phialis, diminutive of phiale, a broad, flat vessel) is a flask-shaped projection from the vesicle (dilated part of the top of conidiophore) of certain fungi. It projects from the mycelium without increasing in length unless a subsequent increase in the formation of conidia occurs. [1]
Phialide - an overview | ScienceDirect Topics
Phialides are generally flask-shaped, comprising a cylindrical basal part and a distinct neck, or lanceolate (with a narrow basal part tapering to a pointed apex). Conidia are produced in long dry chains, divergent, or in columns, are globose, ellipsoidal, cylindrical, or fusiform, hyaline or greenish, smooth or rough-walled.

Three types of phialides occurring on aerial mycelium were identified in Phaeoacremonium (11), i.e., types I, II, and III (Fig. 5). They differ in size and shape (Fig. 6), and the predominance of...

Three types of phialides occurring on aerial mycelium were identified in Phaeoacremonium , i.e., types I, II, and III (Fig. 5). They differ in size and shape (Fig. 6), and the predominance of one or more of the three types is distinctive for certain species. Type I phialides, for which the specialized term adelophialides may also be used, were ...
The term phialide was invented by Vuillemin (1910a), member of a school of French mycologists among whom the use of developmental features in deuteromycete taxonomy can be traced as far back as Costantin (1888).
Penicillium | Mycology | University of Adelaide
Microscopically, chains of single-celled conidia are produced in basipetal succession from a specialised conidiogenous cell called a phialide. The term basocatenate is often used to describe such chains of conidia where the youngest conidium is at the basal or proximal end of the chain.
