Paraconiothyrium maculicutis Verkley & Gruyter, sp. nov.<br />
MycoBank MB564796. Fig. 6.<br />
Etymology: Lat<strong>in</strong>, cutis = sk<strong>in</strong>; maculae = spots.<br />
Pycnidia <strong>in</strong> vitro 50–125 μm diam, globose to subglobose,<br />
glabrous or with mycelial outgrowth, scattered, non-ostiolate<br />
or ostiolate, pycnidial wall made up <strong>of</strong> 5–7 layers <strong>of</strong> cells.<br />
Conidiogenous cells 1.5–3 × 0.5–2.5 μm, <strong>in</strong>determ<strong>in</strong>ate or<br />
ampulliform to filiform <strong>in</strong> a later state, up to 10 μm <strong>in</strong> length.<br />
Conidia 1.5–2.5 × 0.5–1.5 μm, ellipsoidal, <strong>in</strong>itially hyal<strong>in</strong>e, then<br />
discolour<strong>in</strong>g to olivaceous.<br />
Description <strong>in</strong> vitro: Colonies on OA 50–52 mm diam after 7 d,<br />
marg<strong>in</strong> entire; colony olivaceous buff to greenish olivaceous/grey<br />
olivaceous, with greenish olivaceous to pale olivaceous grey,<br />
f<strong>in</strong>ely floccose to woolly aerial mycelium; reverse smoke-grey to<br />
greenish olivaceous, with olivaceous patches. Colonies on MEA<br />
43–44 mm diam after 7 d, marg<strong>in</strong> entire; colony pale olivaceous<br />
grey to greenish olivaceous, with isabell<strong>in</strong>e to c<strong>in</strong>namon at centre,<br />
with compact pale olivaceous grey, f<strong>in</strong>ely floccose to woolly aerial<br />
mycelium; reverse buff to honey, isabell<strong>in</strong>e to olivaceous near<br />
marg<strong>in</strong>. Pycnidia globose to subglobose, olivaceous to brick, f<strong>in</strong>ally<br />
olivaceous black, scattered, ma<strong>in</strong>ly on the agar, 50–125 μm diam,<br />
glabrous or with mycelial outgrowth, non-ostiolate or ostiolate,<br />
pycnidial wall made up <strong>of</strong> 5–7 layers <strong>of</strong> cells. Conidiogenous cells<br />
1.5–3 × 0.5–2.5 μm, ampulliform to filiform <strong>in</strong> a later state, up to 10<br />
μm <strong>in</strong> length. Conidia 1.5–2.5 × 0.5–1.5 μm, av. 1 × 2 μm, length/<br />
width ratio = 1.5–3.2, av. 2.2, ellipsoidal, <strong>in</strong>itially hyal<strong>in</strong>e, then<br />
discolour<strong>in</strong>g to olivaceous. Chlamydospores absent. NaOH spot<br />
test: negative. Crystals absent.<br />
Specimen exam<strong>in</strong>ed: USA, Texas; San Antonio, Fort Sam Houston, from human,<br />
cutaneous lesions, 1989, D.P. Dooley, holotype <strong>CBS</strong> H-20824, culture ex-holotype<br />
<strong>CBS</strong> 101461 = IMI 320754 = UTHSC 87-144.<br />
Notes: Isolate <strong>CBS</strong> 101461 was identified as Pleurophoma<br />
pleurospora (Dooly et al. 1989). However, <strong>in</strong> vitro data and the<br />
molecular phylogeny demonstrate that this isolate does not belong<br />
to Pleurophoma pleurospora, see below, and therefore is described<br />
as a new species <strong>in</strong> the genus Paraconiothyrium.<br />
