Spores: medium sized, subglobose, 4-6 × 4-5 µm in diameter and minutely roughened. Spore-print: white, not blueing in solutions of iodine. _General Information_: _T. atrata_ also grows on burnt soil and is very closely related, but differs in its spores being broadly ellipsoid and smooth. _Mycena leucogala_ also grows on burnt soil (see p. 88). _Illustrations_: _T. anthracophila_--LH 83. _T. atrata_--WD 4^{b}. ~Psathyrella pennata~ (Fries) Pearson & Dennis Bonfire brittle-cap _Cap_: width 10-30 mm. _Stem_: width 1-3 mm; length 30-40 mm. _Description_: Cap: conical or bell-shaped then expanding and slightly umbonate, whitish because of a coating of dense fibrils, but soon becoming brownish as these are lost. Stem: short, stout, white and densely floccose. Gills: slightly adnate, pale brownish grey with pink tinge, then dark-brown. Spore-print: purplish brown. Spores: medium sized, oval, ellipsoid with an obvious germ-pore, purplish brown under the microscope and 8-9 × 4-5 µm in size. Marginal & facial cystidia: flask-shaped, hyaline with either a short or long neck. The brown-spored _Hebeloma anthracophila_ Maire is similar. ~Coprinus angulatus~ Peck Bonfire ink-cap _Cap_: width 4-25 mm. _Stem_: 1-3 mm; length 15-30 mm. _Description_: Cap: dark red-brown at first, then orange-brown, especially at the margin and appearing as if frosted all over, conical at first but rapidly expanding at the margin and becoming grey-brown, strongly striate and deliquescent, leaving finally only a central red-brown umbo. Stem: white and minutely hairy. Gills: free, dirty whitish then black. Spore-print: black-brown. Spores: medium sized, dark brown under the microscope, lobed like the hat of a bishop and 8-11 × 6-8 × 5-7 µm in size. Marginal cystidia: bottle-shaped, very variable. Facial cystidia: similar to marginal cystidia. _General Information_: It must be noted that this fungus has spores which require three quite different measurements to describe the dimension. Another species of _Coprinus_ found on burnt soil is _C. lagopides_ Karsten which resembles _C. cinereus_ (Fries) S. F. Gray (p. 211); it is typified, however, by the rounded spores. [Illustration: Plate 73. Fungi of bonfire-sites] General notes on fungi of burnt sites Several common fungi found at the sites of bonfires have their closest relatives amongst various groups of microscopic fungi more than amongst the large forms already discussed. Keeping a close watch at the site of a former bonfire day by day, week by week and month by month is very rewarding and shows a further example, like the dung habitat, of a tightly knit community of various groups of fungi.
