intricata of hyphae (2.5–)3.0–10.5(–18.5) μm (n = 45) wide, thin-walled, hyaline to dilute olive-yellow, with stronger

pigmentation close to the surface; hyphae in part submoniliform with distinctly see more inflated cells. Asci (89–)93–114(–127) × (4.5–)5.0–5.7(–6.5) μm (n = 30), stipe (7–)10–27(–42) μm (n = 30) long; no croziers seen. Ascospores hyaline, smooth to finely verruculose, cells Adriamycin solubility dmso dimorphic; distal cell (3.5–)3.8–4.5(–5.0) × (3.3–)3.5–3.7(–4.0) μm, l/w (1–)1.1–1.3(–1.5) (n = 30), (sub)globose to ellipsoidal, less commonly wedge-shaped; proximal cell (3.7–)4.4–5.6(–6.2) × (2.7–)2.8–3.0(–3.2) μm, l/w (1.3–)1.5–1.9(–2.2) (n = 30), oblong (to ellipsoidal or subglobose). Habitat: on a Piloderma or Amauroderma sp. on forest debris Distribution: Europe (Estonia) and USA (Delaware). Holotype: Estonia, on a Piloderma (?Amauroderma) sp., 13 Sep. 2000, U. Kõljalg, BPI 843638, ex-type culture TFC 2000-36). Notes: This is one of the few species in Hypocrea that exhibit an entirely prosenchymatous stroma. In addition, it differs from PU-H71 price all other species of the genus in its olive colour. Hypocrea alcalifuscescens is probably fungicolous. In the holotype the corticiaceous host (pale yellow loose mycelium without clamps) grew apparently on bark of Picea or Pinus and saw dust. Whether

the specimen reported by Overton et al. (2006b) from bark of Liriodendron in Delaware, USA represents the same species is unclear, because no gene

sequences from this specimen are available. Hypocrea austriaca Jaklitsch & Voglmayr, sp. nov. Fig. 54 Fig. 54 Teleomorph of Hypocrea austriaca. a–d. Fresh stromata. e–i.
