str. on Eucalyptus. Furthermore, single ascospore isolates of a diaporthalean fungus produced

colonies typical of C. eucalypti in culture. Phylogenetic analyses of sequence data showed that this collection represents a previously undescribed genus and family, which are treated below. Cryptosporiopsis californiae Cheewangkoon, Denman & Crous, Trichostatin A mouse sp. nov. Fig. 3 Fig. 3 Cryptosporiopsis californiae. a. Colony on MEA. b. Conidiomata on MEA. c–k. Conidia and phialidic conidiogenous cells. l. Conidia. Scale bars: b = 150 µm, c–k = 15 µm, l = 10 µm; d applies to d–k MycoBank MB516493. Etymology: Named for the state of California, USA where the fungus was collected. Maculae amphigenae, subcirculares ad irregulares, brunneae. Conidiomata pycnidialia ad acervularia, superficialia vel pro parte immersa, brunnea ad atrobrunnea,

discreta vel confluentia, 80–130 µm diam, 45–70 µm alta. Conidiophora nulla vel ad 1–2 cellulis brevibus reducta sunt. Cellulae conidiogenae discretae, phialidicae, incrassatae, cylindricae, plerumque infra apice leniter inflatae, hyalinae, (4–)8–11(–16) × 2.5–3.5 µm. Conidia elongate ellipsoidea, recta vel leniter curvata, nonnulla inaequilateralia, apex obtusus vel late acutus, basi abrupte angustata hilo leniter protrudente, 1.5–2 µm lato, aseptata, Ku-0059436 molecular weight hyalina, crassitunicata, guttulis 5–30 minutis, (12.5–)15–18(–27.5) × (4.2–)4.5–5.2(–5.8) µm. Leaf spots amphigenous, subcircular to irregular, medium brown. On PNA: mycelium immersed, see more consisting of branched, hyaline to very pale brown, 2.5–3.5 µm wide hyphae. Conidiomata pycnidial to acervular, superficial or partly isometheptene immersed, medium to dark brown, with cream conidial masses; separate or confluent, 80–130 µm diam, 45–70 µm high; wall dark brown, pseudoparenchymatous, thick, composed

of irregular, medium brown cells that become pale brown towards the inner region, 8–15 µm thick; stroma weakly developed, 5–10 µm thick, paler in non-pycnidial conidiomata, consisting of numerous sterile hyphae. Conidiophores absent, or reduced to 1–2 short supporting cells. Conidiogenous cells arise from the inner cells of the cavity, discrete, phialidic, thickened, cylindrical, mostly slightly enlarged below the apex, hyaline, (4–)8–11(–16) × 2.5–3.5 µm. Conidia elongate ellipsoidal, straight or slightly curved, some inaequilateral, apex obtuse or broadly acute, tapering abruptly to a slightly protruding scar at the base, 1.5–2 µm wide; aseptate, hyaline, thick-walled, with 5–30 min guttules per conidium, (12.5–)15–18(–27.5) × (4.2–)4.5–5.2(–5.8) µm. Culture characteristics: Colonies reaching 4 cm diam on MEA after 1 wk at 25°C, slightly raised, olivaceous-grey to buff (surface), with white margin, and dense white aerial mycelium; yellow-brown (reverse).
