“…The remainder of Ericaceae mycorrhizal types are char acterized by a fungal mantle on the root (although this is vari able), a Hartig net that surrounds only the epidermal cells, and hyphae that penetrate epidermal cells (MacDougal & Lloyd, 1900;Henderson, 1919;Christoph, 1921;Zak, 1974;Robertson & Robertson, 1982, 1985Fusconi & BonfanteFasolo, 1984;Massicotte & al., 1993Massicotte & al., , 2005bMassicotte & al., , 2007Massicotte & al., , 2008Massicotte & al., , 2010Young & al., 2002;Osmundson & al., 2007;Kühdorf & al., 2014Kühdorf & al., , 2015; Table 1). These types are similar to typical ECM in having a Hartig net and mantle, but differ in that they penetrate cells; Molina & Trappe (1982) and Brundrett (2004) viewed them as types of ectomycorrhiza (a view also supported by Read, 2008 and and they are sometimes referred to as ectendomycorrhiza (Harley & Harley, 1987).…”

The relationships among pyroloids, monotropoids, arbutoids and the remainder of Ericaceae continue to be unresolved even though significant progress has been made in understanding the phylogenetic structure of the family. This means that, in addition to uncertainty in classification, evolutionary patterns in vegetative structure and mycorrhizal diversity in the family have also been uncertain. This study analyzes nuclear, plastid and mitochondrial sequence data in order to provide a basis for classification and character analysis. Parsimony and maximum likelihood analyses of partitioned and combined data are largely in agreement; organellar data differ from nuclear data with respect to the position of pyroloids. Based on nuclear, plastid and combined data analyses, monotropoids are sister to arbutoids, and these are together sister to pyroloids, and thence to a core Ericaceae and finally to Enkianthus. This suggests that a reduction in woodiness and increased mycotrophy has occurred in parallel in pyroloids and monotropoids and that the arbutoid and ericoid mycorrhizal types were each derived from the arbuscular type in Ericaceae.

“…These include arbutoid (Richard et al 2005;Kühdorf et al 2014), cavendishioid (Setaro et al 2006), ericoid (see below), jungermannoid (Kottke et al 2003;Newsham and Bridge 2010), orchid (e.g., Warcup and Talbot 1967;Dearnaley et al 2009;Wright et al 2010), and pyroloid (e.g., Tedersoo et al 2007;Vincenot et al 2008;Hashimoto et al 2012) mycorrhizae, as well as ectomycorrhizae (e.g., Selosse et al 2002;Urban et al 2003;Wei and Agerer 2011). Sebacinales are phylogenetically divided into two families, namely, Sebacinaceae (formerly Group or Clade A) and Serendipitaceae (Group/Clade B), which also differ in ecology (including mycorrhizal potential) and cultivability (Weiss et al 2004;Oberwinkler et al 2013;Oberwinkler et al 2014;Weiss et al 2016).…”

Experimental evidence of ericoid mycorrhizal potential within Serendipitaceae (Sebacinales)

et al. 2016

The Sebacinales are a monophyletic group of ubiquitous hymenomycetous mycobionts which form ericoid and orchid mycorrhizae, ecto- and ectendomycorrhizae, and nonspecific root endophytic associations with a wide spectrum of plants. However, due to the complete lack of fungal isolates derived from Ericaceae roots, the Sebacinales ericoid mycorrhizal (ErM) potential has not yet been tested experimentally. Here, we report for the first time isolation of a serendipitoid (formerly Sebacinales Group B) mycobiont from Ericaceae which survived in pure culture for several years. This allowed us to test its ability to form ericoid mycorrhizae with an Ericaceae host in vitro, to describe its development and colonization pattern in host roots over time, and to compare its performance with typical ErM fungi and other serendipitoids derived from non-Ericaceae hosts. Out of ten serendipitoid isolates tested, eight intracellularly colonized Vaccinium hair roots, but only the Ericaceae-derived isolate repeatedly formed typical ericoid mycorrhiza morphologically identical to ericoid mycorrhiza commonly found in naturally colonized Ericaceae, but yet different from ericoid mycorrhiza formed in vitro by the prominent ascomycetous ErM fungus Rhizoscyphus ericae. One Orchidaceae-derived isolate repeatedly formed abundant hyaline intracellular microsclerotia morphologically identical to those occasionally found in naturally colonized Ericaceae, and an isolate of Serendipita (= Piriformospora) indica produced abundant intracellular chlamydospores typical of this species. Our results confirm for the first time experimentally that some Sebacinales can form ericoid mycorrhiza, point to their broad endophytic potential in Ericaceae hosts, and suggest possible ericoid mycorrhizal specificity in Serendipitaceae.

“…and Leotia cf. lubrica have been described so far (Osmundson et al 2007; Kühdorf et al 2014, 2015). However, typical as well as presumable ectomycorrhizal forming species of the genera Cortinarius , Hysterangium , Laccaria , Tricholoma and Phaeocollybia , have also been mentioned from the páramo by Halling and Mueller (1999).…”

Arbutoid mycorrhizas of Comarostaphylis arbutoides (Arbutoidea, Ericaceae) from neotropical montane forests are rarely described. To date, only mycorrhizal associations with the fungal species Leccinum monticola, Leotia lubrica and Sebacina sp. are known from literature. The genus Cortinarius is one of the most species-rich ectomycorrhizal taxa with over 2000 assumed species. In this study, two sites in the Cordillera de Talamanca of Costa Rica were sampled, where Com. arbutoides is endemic and grows together with Quercus costaricensis. Using a combined method of rDNA sequence analysis and morphotyping, 33 sampled mycorrhizal systems of Cortinarius were assigned to the subgenera Dermocybe, Phlegmacium and Telamonia. Specific plant primers were used to identify the host plant. Here, we present the phylogenetic data of all found Cortinarii and describe four of the arbutoid mycorrhizal systems morphologically and anatomically.
