Crous et al. Fig. 12. Penidiella rigidophora (type material). A–F. Micronematous conidiophores giving rise to chains of conidia. G–H. Macronematous conidiophores (note base in G, and apex in H). I. Conidia. Scale bars = 10 µm. Specimen examined: Cuba, isolated from leaf litter of Smilax sp. (Smilacaceae), 6. Nov. 1994, R.F. Castañeda, holotype CBS H-19938, culture ex-type CBS 314.95. Notes: Cladosporium rigidophorum is a herbarium name, which was never validly published. The ex-type strain, however, represents a new species of Penidiella, for which a valid name with Latin diagnosis is herewith provided. This species is easily distinguishable from all other taxa of Penidiella by forming distinct constrictions at hyphal and conidial septa as well as micronematous conidiophores (except for P. venezuelensis in which a few micronematous conidiophores have been observed). It is also phylogenetically distinct from the other taxa of Penidiella (see Fig. 1 in Crous et al. 2007a – this volume). 22
Phylogenetic lineages in the Capnodiales Penidiella strumelloidea (Milko & Dunaev) Crous & U. Braun, comb. nov. MycoBank MB504514. Figs 14–15. Basionym: Cladosporium strumelloideum Milko & Dunaev, Novosti Sist. Nizsh. Rast. 23: 134. 1986. Mycelium consisting of branched, septate, smooth, hyaline to pale olivaceous, 1–4 µm wide hyphae, sometimes constricted at somewhat darker septa. Conidiophores solitary, erect, arising from superficial mycelium, micronematous, i.e., reduced to conidiogenous cells, or macronematous, subcylindrical, straight to slightly curved, subcylindrical throughout or often somewhat attenuated towards the apex, 12–80 × (2–)2.5–4 µm, 0–6-septate, medium brown, smooth, wall ≤ 0.75 µm, penicillate apex formed by a terminal conidiogenous cell giving rise to a single set of ramoconidia. Conidiogenous cells terminal, integrated, subcylindrical, straight, 8–12 × 1.5–2(–2.5) µm, pale brown, thin-walled, smooth, apex obtusely rounded to somewhat clavate; loci terminal, occasionally subterminal or lateral, unthickened or almost so to slightly thickened and darkened, not refractive, 1–1.5 µm wide. Conidia in branched chains; ramoconidia subcylindrical, with 1–3 terminal loci, olivaceous-brown, smooth; secondary conidia ellipsoidal, with one side frequently straight and the other convex, straight to slightly curved, (8–)10–12(–20) × 2(– 3) µm, subhyaline to olivaceous-brown, smooth, thin-walled; hila unthickened or almost so to somewhat thickened and darkened, not refractive, 1 µm wide. Cultural characteristics: Colonies on PDA erumpent, spreading, with abundant, dense to woolly aerial mycelium, and uneven, feathery margins; surface pale olivaceous grey, reverse iron-grey. Colonies reaching 25 mm diam after 1 mo at 25 °C in the dark; colonies fertile. Fig. 13. Penidiella rigidophora (type material). A. Hyphae. B. Conidiophores. C. Ramoconidia. D. Secondary conidia. Scale bar = 10 µm. U. Braun del. Specimen examined: Russia, Yaroslavl Region, Rybinsk Reservoir, mouth of Sutka River, isolated from leaf of Carex sp. (Cyperaceae), from stagnant water, S. Ozerskaya, holotype BKMF-2534, culture ex-type CBS 114484. Fig. 14. Penidiella strumelloidea (type material). A–B. Micronematous conidiophores. C–D. Macronematous conidiophores. E–G. Conidia. Scale bars = 10 µm. www.studiesinmycology.org 23
