<strong>Cladosporium</strong> herbarum species complex<br />
Fig. 17. <strong>Cladosporium</strong> herbarum (CPC 11600). Macro- <strong>and</strong> micronematous conidiophores <strong>and</strong> conidia. Scale bar = 10 µm. K. Schubert del.<br />
Literature: de Vries (1952: 71), Hughes (1958: 750), Ellis (1971:<br />
313), Domsch et al. (1980: 204), Sivanesan (1984: 225), Ellis &<br />

Notes: De Vries (1952) incorrectly selected a specimen of Link’s<br />
herbarium at herb. B as lectotype. Prasil & de Hoog (1988) discussed<br />
this typification <strong>and</strong> designated one of Persoon’s original specimens<br />
as lectotype in which C. herbarum could be recognised. <strong>The</strong> latter<br />
material, which is in poor condition, could be re-examined within<br />
the course of these investigations <strong>and</strong> showed conidia agreeing<br />
with the current species concept of C. herbarum being (6–)9.5–<br />
14.5(–21) × (5–)6–7(–8) µm. Since the identity of the strain <strong>CBS</strong><br />
177.71 chosen by Prasil & de Hoog (1988) as representative living<br />
strain of C. herbarum could not be corroborated, an epitype with<br />
a living ex-epitype culture is designated. <strong>The</strong> holotype specimen<br />
of D. tassiana (RO) is morphologically <strong>similar</strong> to that observed on<br />
the epitype of C. herbarum, having ascospores which are (17–)21–<br />
www.studiesinmycology.org<br />
23(–25) × (6–)7–8(–8.5) µm, turning brown <strong>and</strong> verruculose in asci<br />
with age. However, no hamathecial remnants were observed in<br />
ascomata in vivo.<br />
<strong>The</strong> connection to the teleomorph D. tassiana could be<br />
confirmed, which is in agreement with the findings of von Arx (1950)<br />
<strong>and</strong> Barr (1958). Ascospore isolates formed the typical C. herbarum<br />
anamorph in culture, <strong>and</strong> these anamorph cultures developed<br />
some immature fruiting bodies within the agar. When inoculated<br />
onto water agar plates with nettle stems, numerous ascomata with<br />
viable ascospores were formed in culture.<br />
