VOLUME 13 DECEMBER 31, 2007 Notes on ascomycete systematics Nos. 4408 - 4750 H. Thorsten Lumbsch and Sabine M. Huhndorf (eds.) The Field Museum, Department of Botany, Chicago, USA Abstract Lumbsch, H. T. and S.M. Huhndorf (ed.) 2007. Notes on ascomycete systematics. Nos. 4408 – 4750. Myconet 13: 59 – 99. The present paper presents 342 notes on the taxonomy and nomenclature of ascomycetes (Ascomycota) at the generic and higher levels. Introduction The series ”Notes on ascomycete systematics” has been published in Systema Ascomycetum (1986-1998) and in Myconet since 1999 as hard copies and now at its new internet home at URL: http://www.fieldmuseum.org/myconet/. The present paper presents 342 notes on the taxonomy and nomenclature of ascomycetes (Ascomycota) at the generic and higher levels. The date of electronic publication is given within parentheses at the end of each entry. Notes 4476. Acanthotrema A. Frisch that the genera Acarospora, Polysporinopsis, and Sarcogyne are not monophyletic in their current This monotypic genus was described by Frisch circumscription; see also notes under (2006) to accommodate Thelotrema brasilianum; Acarospora (4477) and Polysporinopsis (4543). see note under Thelotremataceae (4561).

(2006) to lichenized species collected twice in lowland dry a monophyletic group of taxa related to the type forests of NW Costa Rica (Aptroot et al. 2006). species A. schleicheri. The A. smaragdula group It is placed in Ramalinaceae based on ascus-type. and A. badiofusca are excluded from the genus Similar genera include Bacidiopsora Kalb and in a strict sense. (2006-10-18) Squamacidia Brako. The latter is said to differ by thallus morphology and unexplained details of apothecia, while the former differs in 4478. Acarosporaceae Zahlbr. morphology, apothecial pigmentation, ascospore The delimitation of genera in this family is morphology and thallus chemistry. The genus studied by Crewe et al. (2006) who demonstrate will be accepted in the forthcoming outline in 59 Ramalinaceae, but additional studies – including Thell et al. 2004) supported its inclusion in molecular data – appear necessary to elucidate Parmeliaceae. Consequently, Anzia will be the placement of the genus. (2006-12-20) included in Parmeliaceae in the next outline. (2006-05-30) 4569. Almbornia Essl. 4450.

This genus was described in Gryzenhout et al. (2005) and will be placed in Cryphonectriaceae This genus was described by Matsushima (2003) following Gryzenhout et al. (2006); see note for a species isolated from palm fronds and under Cryphonectriaceae (4497). (2006-10-18) forming the teleomorph and a Cercosporula anamorph in culture. It is placed in the Sordariomycetidae inc. sed. until its affinities 4480. Ampliotrema Kalb can be established. (2006-10-18) This genus was described by Kalb (2004), but the description lacked a generic type. The name 4616. Aporothielavia Malloch & Cain has been validated by Frisch (2006). However, Frisch (2006) discussed the similarities to Greif and Currah (2007) studied the ascoma Ocellularia and Frisch et al. (2006) showed that development in this monotypic genus and Ampliotrema is nested within a strongly showed that A. leptoderma belongs in supported Ocellularia s.str. Consequently, Chaetomidium. Consequently, Aporothielavia is Ampliotrema will be regarded a synonym of placed into synonymy with that genus.

It was previously believed to belong to sequences (Vijaykrishna et al. 2005) the family Thelenellaceae, but del Prado et al.

It Ophiostomatales and another clade basal to these should be noted that the generic concept in this two groups. (2006-05-30) family requires revision. (2007-06-05) 4409. Annulohypoxylon Y.-M.

(2006) described two new taxa in Based on deviating ascospores this family is this yeast genus using molecular data to support often kept separate from Parmeliaceae (e.g., their decision. The genus was previously Kärnefelt & Thell 1992). However, it agrees included in Saccharomycopsis in the outline, but with the latter family in ascomatal anatomy and previously Naumov et al. (2003) provided molecular studies (Mattsson & Wedin 1999, evidence from a phylogenetic analysis inferred 60 from nu LSU rDNA sequences that Arthroascus contradictive to molecular phylogenies in placing is a distinct lineage.
