Subgenus Nolanea

Subgenus Nolanea is very rich, both in number of species and in appearance. The typical habit is that of a Mycena species, more rarely it reminds of a Collybia or Omphalia. Microscopically Nolanea is characterized by a trama which is build up of fusiform elements, up to 200-300 µm long. Clamps usually are scarce, and to be found in greater numbers only in the hymenium, and more rarely also in the covering layer of the pileus. The spores are never cuboid or cruciform (see section Staurospora in subgenus Inocephalus).

sect. Nolanea

Habit slender, usually with a relatively long stem. The lamella edge usually is sterile with abundant clavate to (sub)capitate cheilocystidia. Pigment intracellular and incrusting. Clamps present.

Species: E. hirtipes (Schum.: Fr.) Mos.; E. hebes (Romagn.) Trimbach; E. kuehnerianum (Kühner) Noordel.

sect. Papillata

Habit slender. Pigment in pileipellis incrusting, sometimes in combination with intracellular pigment. Cystidia usually absent. Clamps usually present.

sect. Endochromonema

The name of this section refers to the predominantly intracellular pigment in the pileipellis. This section, which is rich in species, is divided in a number of subsections:

• pileus smooth; pileipellis a cutis
  • with green-yellow tinges
    • subsect. Icterina
  • with cheilocystidia
    • subsect. Cheilocystidiati
  • without cheilocystidia; stipe fibrillose-striate
    • subsect. Endochromonemaa
  • without cheilocystidia; stipe polished
    • subsect. Infularia
• Pileus finely fibrillose-woolly, particularly at centre; pileipellis a transition to a trichoderm
  • subsect. Tristia

Species:

• Subsect. Endochromonema: (Fr.: Fr.) Mos.; E. farinogustus Arnolds & Noordel.; E. calthionis Arnolds & Noordel.; E. ventricosum Arnolds & Noordel.; E. cuneatum (Bres.) Mos.; E. pallescens (Karsten) Noordel.; E. lanuginosipes Noordel.; E. occultopigmentatum Arnolds & Noordel.; E. testaceum (Bres.) Noordel.; E. dolorosum Noordel. & Wölfel
• Subsect. Cheilocystidiata: E. velenovskyi Noordel.; E. pratulense Noordel.;E. langei Noordel. & Borgen; E. magnaltitidinis Noordel. & Senn- Irlet ; E. cryptocystidiatum Arnolds & Noordel.; E. inutile (Britz.) Noordel.; E. globuliferum Noordel.
• Subsect. Infularia: E. infula (Fr.: Fr.) Noordel.; var. infula; var. chlorinosum (Arnolds & Noordel.) Noordel.; E. solstitiale (Fr.) Noordel.; E. verecundum (Fr.: Fr.) Noordel.
  
• Subsect. Icterina: E. pleopodium (Bull. ex DC: Fr.) Noordel.; E. chlorophyllum Noordel.; E. ambrosium (Quél.) Noordel.
  
• Subsect. Tristia: E. triste (Velen) Noordel.; E. undulatosporum Arnolds & Noordel.; E. winterhofii Wölfel & Noordel.

sect. Fernandae

Section Fernandae is formed by a small group of rather similar species, characterized by a pileipellis which is a cutis or a transition to a trichoderm, made up of slightly to distinctly inflated terminal elements with a rather characteristic pigmentation of incrusted walls ánd dark intracellular pigment clots in the hyphae. Clamps are always absent. They usually grow on rather poor, acid soils in grasslands, heaths, and coniferous forests. They are considered to form a bridge to subgenus Pouzarella

Species: E. fernandae (Romagn) Noordel.; E. defibulatum Arnolds & Noordel.; E. xanthocaulon Arnolds & Noordel.; E. cuniculorum Arnolds & Noordel.; E. acidophilum Arnolds & Noordel. E. argenteostriatum Arnolds & Noordel.; E. kristiansenii Noordel

sect. Canosericei

Also this section seems to form a bridge to subgenus Pouzarella in particular to sect. Versatilia with its differnetiated cutis with intracelluar and incrusting pigment, and voluminous, fusiform cheilocystidia. Contrary to sect. Versatilia clamps usually are present.

Species: E. canosericeum (J.Lange) Noordel.; E. amicorum Noordel.
