Could this be Cheilymenia granulata var. elaphorum?
Jan Knuiman, 01-07-2018 16:33
Hello,

These discs (max.diameter 1 mm) were found on excrements of Galloway cattle. No hairs on margin or flanks. Spores showed no ornamentation in cotton blue / lactic acid. Free spores mounted in tap water measured 15.0-18.0 x 7.4-8.9 µm. Paraphyses with yellow guttuli and maximum width at the top of 5 µm. Textura of the excipulum consisting of large more or less globose to angular cells. 

Could this be Cheilymenia granulata var. elaphorum?

Herweith I add an extra picture showing some linear striation on the spores.

Hi Jan,

in my opinion the paraphyses for Ch. elaphorum are too slim. I think, one can look at Ch. theleboloides. At some collections of Cheilymenia the hairs are very difficult to find.

Greetings Peter.

Re : Could this be Cheilymenia granulata var. elaphorum?
Hello Peter, 

Thanks for your reply! I made five extra preparations and found four hairs in total! Very difficult to find indeed! The hairs varied in length between 65 and 305 µm. 

Does this confirm C. theleboloides?

Hi Jan,

after hairs of Cheilymenia don't look in my opinion. Do you have the world monograph of MORAVEC (2005) about this genus ?

Greetings Peter.

Re : Could this be Cheilymenia granulata var. elaphorum?
Hello Peter,

Unfortunately, I don't have the 2005 monograph, but do have access to the Mycotaxon 38, 1990 paper of Moravec. In that paper Moravec describes the hairs of C. theleboloides as: "although the latter possesses not only hyaline hyphoid hairs with a bulbous base, but also yellowish acuminate hairs with "germs" of roots. The latter consist usually of a bifurcate base of bulbous "primitive germs of roots". However, apothecia of many collections of C. theleboloides possess only hyphoid hairs and lack the acuminate yellowish hairs, or these hairs occur very rarely."

I've have searched the material once more and found two hairs of about 60 µm and similar to the ones already found, and one longer hairlike structure of about 300 µm (see pictures).

I agree with you that the illustrations on p. 463 of Moravec's paper suggest that the hairs should be septate and have a furcate base. These aspects are not visible in the hairs I've found. Could it be that the hairs do not belong to the specimen found? Or are there other options for the combination of characteristics of this specimen?

Kind regards,
Jan

Hi Jan,
the hair do not belong in my opinion to the mushroom, likely of vegetable origin.

I try to send you the monograph.

Greetings Peter.

Re : Could this be Cheilymenia granulata var. elaphorum?
Hi Peter,

It would be fine, if you could send me the monograph! So, you still think C. theleboloides is the best option for this mushroom?

Kind regards,
Jan
