Entoloma s.l. (supplemento)
This supplement to Vol 5 is almost as long as the original. Is it a supplement or a new edition? It really is a supplement - it's consecutively numbered and refers back to vol 5 for species already described, so all the information presented is new. This takes the number of species covered from 246 to 342, with 40 new taxa formally described.
Revised keys begin on p806. The structure is slightly changed, but the most welcome improvement is that the difficult characters of encrusting/intracellular pigment and clamp connection at base of basidium are moved much later in the keys.
The species accounts follow the format of Vol 5, but have been renumbered. Species already covered in Vol 5 are reduced to a title line, maybe followed by some additional information, eg new iconographic references.
A major feature is the large number of colour photographs, mostly of good quality. They are numbered with the species numbers. There are some surprising look-alikes: Russula (5), Mycena rosea (160), Resinomycena saccharifera (324), Phaeotellus (337). Some familiar fungi need to be checked more closely!
The index is very sparse, listing only specific epithets. This is much less confusing than Vol 5's two indexes with multiple page references. Both volumes are indexed using bold face for descriptions, italics for colour illustrations.
The photo on the front cover is Machiel's own photograph of Entoloma noordeloosii - a nice touch!

Key 3, p811. This key is only to species with PILEUS NOT BLUE/BLACK (and blue stipe and coloured lamella edge). Blue/black-capped species with coloured gill edge start at key 2.5.
Key 7, p816. Couplet 7. The colours in key and descriptions are at odds with the photographs.
Key 8, p816. Couplet 6, 2nd alternative should go to 22.
Couplet 7, 2nd alternative should go to 16.
Key 8, p817. Couplet 21, E. parkensis is keyed out on the basis of intracellular pigment but the description emphasises encrusting piment.
Key 9, p818. Couplet 5, 1st alternative should go to 6.
Key 9, p818. Couplet 3 states that cheilocystidia are absent in E. rugosum, but the description, (Vol 5, p629) says: "cheilocystidia scattered or in clusters among basidia" and illustrates them (p619). Furthermore the description of E. sericellum (Vol 5, p415) describes the stipe as "sometimes pruinose ... at apex" and the footnote states that it sometimes has only one or two cystidia per lamella! Perhaps these two are better distinguished by spore outline?
Key 10, p822. Couplet 1, 1st alternative should go to 2.
Key 14, p829. Couplet 20, 1st alternative should go to 21.
P831: couplet 47: 1st alternative should read "Pileus horn-brown to red-brown…"
Key 16, p832. Couplet 1, 2nd alternative should go to 2.
E. dysthales often has a fetid smell (?like E. pseudodysthales), but it can be very fleeting. (MWS)
Entoloma lucidum is described as having cap "sepia-horn or dark sepia" (Orton, 1960) but Photo 92 (p1222) shows pale fulvous caps. |
| Coverage |
Descriptions of nearly 100 European species added since Vol 5 was publishd in 1992, plus full keys. |
| Illustrations |
Line drawings accompany text, followed by 200 plates containing 389 colour photographs at the back. |
| Identify |
Under a Compound Microscope. |
| Specimen Prep. |
Microscope slide preps of spores, cystidia, cap cuticle and basidial clamps. |
| Difficulty |
Entoloma is a difficult group, but after a little practice they can, at last, be identified with some confidence. The photos are very helpful, but not all species are illustrated. Because the toadstools are so variable, and distinguishing related species often relies on microscopy, identification from the pictures alone will be misleading. |
