FRAGNER P. (1980): Pityrosporum ovale and its cultivation from the scalp.  Česká Mykologie 34(1): 29-34   (published: 1980)
  abstract   The introduction reviews the possible pathogenicity of Pityrosporum ovale (Bizzozero 1884) Castellani et Chalmers and its differentiation from Pityrosporum orbiculare Gordon. Methods and results are presented, including descriptions of microscopic and macroscopic features of cultures grown from pathological manifestations on the scalp. P. ovale is a lipophilic yeast known for more than 100 years, but its cultivation and diagnosis remain challenging. Although once considered a saprophyte, P. ovale is now seen as the causative agent of pityriasis simplex capillitii due to its response to treatment with econazole nitrate.

OTČENÁŠEK M., DVOŘÁK J. (1985): Fungi infecting man. Taxonomy of agents of human mycoses in an alphabetical survey.  Česká Mykologie 39(3): 155-164   (published: 1985)
  abstract   An orientational survey of taxonomy of fungi which have been described as agents of human mycoses is given. An alphabetical list of 163 agents contains data on synonyms of the individual species and organs afflicted by them. The literature citation of the earliest paper calling attention to pathogenicity is provided. Current nomenclature of anamorph and teleomorph stages and their mutual relation is discussed.

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.

FRAGNER P. (1971): Pityrosporum orbiculare und seine Züchtung.  Česká Mykologie 25(4): 219-230   (published: 1971)
  abstract   Microscopic findings in skin scales from pityriasis versicolor were studied. Various methods for cultivating Pityrosporum orbiculare were tested. The organism showed both yeast and filamentous forms depending on environmental conditions and steroid levels, resembling Malassezia furfur.
