Are the Species of Penicillium as Imperfect as We Think?
Brefeld (1874) was the first to report the development of a Penicillium teleomorph, giving detailed descriptions of the formation of sclerotioid ascomata and their maturation from the centre outwards. Later studies on Penicillium teleomorphs were carried out by Emmons (1935), Benjamin (1955), Stolk and Scott (1967) and Scott (1968). Malloch and Cain (1972) proposed the family Trichocomaceae Fischer as the appropiate one for species of cleistothecial Ascomycetes with Aspergillus, Paecilomyces, and Penicillium anamorphs. Udagawa and Horie (1973) suggested the division of the genus Eupenicillium on the basis of ascospore ornamentation, as viewed with the scanning electron microscope, without including the anamorphs in their considerations.
