<strong>Cladosporium</strong> <strong>and</strong> morphologically <strong>similar</strong> genera<br />

Fig. 11. Ochrocladosporium frigidarii (type material). A. Macro- <strong>and</strong> microconidiophores. B. Foot cell of macroconidiophore. C–D. Microconidiophore. E–J. Macroconidiophores.<br />

K. Conidia. Scale bars = 10 µm.<br />

are distinct from <strong>Cladosporium</strong> s. str. <strong>The</strong> phylogenetic analysis of<br />

its LSU sequence places it in the Pleosporales, together with O.<br />

elatum.<br />

<strong>The</strong> dimorphic conidiophores seen in O. frigidarii (<strong>CBS</strong> 103.81)<br />

are less obvious in O. elatum (<strong>CBS</strong> 146.33), but the scars <strong>and</strong> hila<br />

are <strong>similar</strong>. <strong>The</strong> macronematous conidiophores of O. frigidarii are<br />

much longer <strong>and</strong> wider <strong>and</strong> the conidia are shorter <strong>and</strong> slightly<br />

wider, (6–)7–8(–10) × (4–)4.5–5(–6) µm, than those of O. elatum<br />

which are (7–)8–10(–14) × (3–)4(–4.5) µm.<br />
